Was Grice a logical corpuscularian? It seems so. After all, he wrote an essay, "Definite descriptions in Russell and in the vernacular", by vernacular meaning Strawson; and while Grice agrees that both Russell and Strawson make a 'common mistake', Grice feels he has a foot on each camp
(Russell's and Strawson's).
Grice's manoeuvre is to re-interpret what
Russell saw as an entailment (and Strawson ignored) as an
implicature.
When Myro published (rather posthumously published) his
"Logic" he makes much of the atomic-molecular distinction as applied to
propositions, and it's noteworthy that Grice's claim to fame (among
logicians) was his implicatural analysis of two-place operators, that
make up for MOLECULAR propositions.
So a purist could say that Grice was
the greatest molecularist of all.
But surely a molecule is composed of corpuscules, too.
Why did Russell describe his philosophy as a kind of
"logical atomism" and not the more correct 'corpuscularism'?
After all,
Russell just meant to endorse both a metaphysical view and a certain
methodology for doing philosophy.
The metaphysical view amounts to the
claim that the world consists of a plurality of independently existing
things exhibiting qualities and standing in relations.
But as Grice says,
every school boy (at least at Clifton, which he attended) knows that.
"There must be more to Russell's logical atomism."
According to logical
atomism, all truths are ultimately dependent upon a layer of atomic
facts, which consist either of a simple particular exhibiting a quality,
or multiple simple particulars standing in a relation.
The
methodological view recommends a process of conceptual analysis, whereby
one attempts to define or reconstruct more complex notions or vocabularies in terms of simpler ones.
According to Russell, at least early on during his logical atomist phase, such an analysis could
eventually result in a language containing only words representing
simple particulars, the simple properties and relations thereof, and
logical constants, which, despite this limited vocabulary,
could
adequately capture all truths. Russell's logical atomism had a profound
influence on analytic philosophy, including Grice, if only to criticise
it.
Ideed, it is arguable that the very name “analytic
philosophy” derives from Russell's defense of the method of analysis.
And while Austin used to say
i. Some like Witters, but Moore's MY
man.
Grice could have said:
ii. Some like Witters, but Russell's
MY man.
Trust Ayer, who was an 'enfant terrible' to attempt to trump
both:
iii. Some like Witters, but Moore and Russell are MY
men.
(vide Ayer: Russell and Moore: the anaytical heritage").
Russell introduced the phrase “logical atomism” to describe his philosophy in
1911.
Russell's logical atomism is perhaps best described as partly a
methodological viewpoint, and partly a metaphysical theory.
Methodologically, logical atomism can be seen as endorsement of
conceptual analysis, understood as a two-step process in which one
attempts to identify, for a given domain of inquiry, set of beliefs or
scientific theory, the minimum and most basic concepts and vocabulary in
which the other concepts and vocabulary of that domain can be defined or
recast, and the most general and basic principles from which the
remainder of the truths of the domain can be derived or reconstructed.
Metaphysically, logical atomism is the view that the world consists in a
plurality of independent and discrete entities, which by coming
together form facts.
According to Russell, a fact is a kind of complex,
and depends for its existence on the simpler entities making it up.
The
simplest sort of complex, an atomic fact, was thought to consist either
of a single individual
exhibiting a simple quality, or of multiple
individuals standing in a simple relation.
The methodological and
metaphysical elements of logical atomism come together in postulating the
theoretical, if not the practical, realizability of a fully analyzed
language, in which all truths could in principle be expressed in a
perspicuous manner.
Such a “logically ideal language”, as Russell at times
called it, would, besides logical constants,
consist only of words
representing the constituents of atomic facts.
And Grice says Russell is
"okay" only he misses to even THINK such a logically ideal language should
invite this or that implicature.
Russell impertinently responded:
"Implicature happens, so?"
In such a language, the simplest sort
of complete sentence would be what Russell called an “atomic
proposition”, containing a single predicate or verb representing a
quality or relation along with the appropriate number of proper
names, each representing an individual.
The truth or falsity of an atomic proposition would depend entirely on a corresponding atomic fact.
The other sentences of such a language would be derived either by combining atomic propositions using truth-functional connectives, yielding molecular propositions, or by replacing constituents of a
simpler proposition by variables, and prefixing a universal or
existential quantifier, resulting
in general and existential
propositions. According to the stronger form of logical atomism Russell
at times adopted, he held that in such a language, "g]iven all true
atomic propositions, together with the fact that they are all, every
other true proposition can theoretically be deduced by logical
methods".
This puts the truth or falsity of atomic propositions at the
core of
Russell's theory of truth, and hence, puts atomic facts at the
center of
Russell's metaphysics.
Russell himself dated his first
acceptance of logical atomism to the
vintage year of 1899 (what Grice
called "that year of Grice") when he and
Moore
rejected the main
tenets of the dominant school of philosophy in Oxford
at the time --
oddly, since both were at Cambridge -- (and to which both
had previously
been adherents), the tradition of neo-Hegelian Idealism
exemplified in
works of F.H. Bradley, and adopted instead a fairly
strong form
of
realism. Of their break with idealism, Russell wrote that "Moore led
the
way, but I followed closely in his footsteps".
**************** WHY
NEITHER RUSSELL NOR GRICE LIKED BRADLEY -- "MUCH"
------
Moore
published an essay entitled “The Nature of Judgment”, in which he
outlined his main reasons for accepting the new realism. It begins
with
a
discussion of a distinction made by Bradley between different
notions of
idea. According to Bradley, the notion of idea understood as a
mental
state or mental occurrence is not the notion of “idea” relevant to
logic or
to truth understood as a relationship between our ideas and
reality.
Instead, the relevant notion of idea is that of a sign or symbol
representing
something other than itself, or an idea understood as
possessing
meaning.
Bradley understood meaning in terms of "a part
of the content of an idea
cut
off, fixed by the mind, and considered
apart from the existence of the
sign". Moore agreed with Bradley that it
is not the mental occurrence
that
is important to logic. However,
with regard to Bradley's second notion
of “
idea”, Moore accused
Bradley of conflating the symbol with the
symbolized, and rejected
Bradley's view that what is symbolized is itself
a part of
the idea
and dependent upon it.
Moore introduces the term "concept" for the
meaning of a symbol; for
Moore, what it is for different ideas to have a
common content is for
them to
represent the same concept. However,
the concept itself is independent of
the ideas. When we make a judgment,
typically, it is not our ideas, or
parts of our ideas, which our judgment
is about. According to Moore, if
I
make an assertion, what I assert
is nothing about my ideas or my mental
states, but a certain "connexion
of concepts". Moore went on to
introduce the
term “proposition” for
complexes of concepts such as that which would
be
involved in a belief
or judgment. While propositions represent the
content
of judgments,
according to Moore,
they and their constituents are entirely independent
from the judging
mind. Some propositions are true, some are not.
For Moore, however, truth is not a correspondence relationship
between
propositions and reality, as there is no difference between a
proposition —
understood as a mind-independent complex — and that
which would make it
true. The facts of the world then consist of true
propositions,
themselves
understood as complexes of concepts.
According to Moore, something
"becomes intelligible first when it is
analyzed into its constituent
concepts".
Moore's "The Nature of
Judgment" had a profound influence on Russell,
who
later heralded it
as the first account of the “new philosophy” to which
he
and Moore
subscribed. For his own part, Russell often described his
dissatisfaction
with the dominant Idealist (and largely monist)
tradition as
primarily having to do with the nature and existence of relations.
In particular, Russell took issue with the claim found in Bradley and
others, that the notion of a fundamental relation between two distinct
entities is incoherent. Russell diagnosed this belief as stemming from
a
widespread logical doctrine to the effect that every proposition
is
logically
of subject-predicate form. Russell was an ardent
opponent of a position
known as the “doctrine of internal relations”,
which Russell stated as
the
view that "every relation is grounded
in the natures of the related
terms". Perhaps most charitably
interpreted, this amounts to the claim
that a's
bearing relation R to
b is always reducible to properties held by a and
b
individually, or
to a property held by the complex formed of a and b. In
the period
leading up to his own abandonment of idealism, Russell was
already
pursuing a research program involving the foundations of
arithmetic.
This work, along with his earlier work on the foundations of geometry,
had
convinced him of the importance of relations for mathematics.
However,
Russell found that one category of relations, viz., asymmetrical
transitive
relations, resisted any such reduction to the properties
of the relata
or
the whole formed of them. These relations are
especially important in
mathematics, as they are the
sort that
generates series.
Consider the relation of being taller than, and
consider the fact that
iv. Shaquille O'Neal is taller than Michael
Jordan.
It might be thought that this relation between O'Neal and
Jordan can be
reduced to properties of each. O'Neal has the property of
being 7'2''
tall,
and Jordan has the property of being 6'6'' tall,
and the taller than
relation in this case is reducible to their
possession of these
properties.
The problem, according to Russell, is
that for this reduction to hold,
there
must be a certain relation
between the properties themselves. This
relation would account for the
ordering of the various height
properties, putting the property of
being-6'8''-tall in between that of
being-7'2''-tall and that of
being-6'6''-tall. This relation among the
properties would itself be an
asymmetrical and transitive relation, and
so the
analysis has not rid
us of the need for taking relations as ultimate.
Another hypothesis would
be that there is such an entity as the whole
composed of O'Neal and
Jordan, and that the relation between the two men
is
reducible to some
property of this whole. Russell's complaint was that
since
the whole
composed of O'Neal and Jordan is the same as the whole
composed of
Jordan and O'Neal, this approach has no way to explain what the
difference would be between O'Neal's being taller than Jordan and
Jordan's being
taller than O'Neal, as both would seem to be reduced to
the same
composite
entity bearing the same quality. Russell's
rejection of the doctrine of
internal relations is very important for
understanding the development
of
his atomistic doctrines in more than
one respect.
Certain advocates of the claim that a relation must
always be grounded
in
the nature of its relata hold that in virtue of
a relating to b, a must
have a complex nature that includes its
relatedness to b. Since every
entity presumably bears some relation to
any other, the nature of any
entity
could arguably be described as
having the same complexity as the universe
as
a whole (if indeed, it
even makes sense on such a picture to divide the
world into distinct
entities at all, as many denied). Moreover,
according
to some within
this tradition, when we consider a, obviously we do not
consider all its
relations to every entity, and hence grasp a in a way
that
falsifies
the whole of what a is. This led some to the claim that “
analysis
is
falsification”, and even to hold that when we judge that a is the
father
of b, and judge that a is the son of c, the a in the first
judgment is
not strictly speaking the same a as involved in the second judgment;
instead, in the first we deal only with a-quâ-father-of-b in the first,
and
a-quâ-son-of-c in the second. In contradistinction to these
views,
Russell
adopted what he called “the doctrine of external
relations”, which he
claimed “may be expressed by
saying that
A) relatedness does not imply any corresponding complexity in the
relata.
B) any given entity is a constituent of many different
complexes.
This position on relations allowed Russell to adopt a
pluralism in which
the world is conceived as composed of many distinct,
independent
entities,
each of which can be considered in isolation
from its relations to other
things, or its relation to the mind.
Russell claimed that this doctrine
was the fundamental doctrine of his
realistic position, and it represents
perhaps the most important turning
point in the development of his
logical
atomism. Russell's first
published account of his newfound realism came
in
the classic The
Principles of Mathematics. Part I is dedicated largely
to a
philosophical inquiry into the nature of propositions. Russell took
over from Moore the conception of propositions as mind-independent
complexes; a true proposition was then simply identified by Russell
with a fact.
However, Moore's characterization of a proposition as a
complex of
concepts was largely in keeping with traditional Aristotelian
logic in
which all
judgments were thought to involve a subject
concept, copula and
predicate
concept. Russell, owing in part to his
own views on relations, and in
part from his adopting certain doctrines
stemming from Peano's symbolic
logic, sought to refine and improve upon
this characterization. In the
terminology introduced by Russell,
constituents of a proposition occur
either as
term or as concept. An
entity occurs as term when it can be replaced by
any other entity and
the result would still be a proposition, and when
it
is one of the
subjects of the proposition, i.e., something the
proposition is about.
An entity occurs as concept when it occurs
predicatively,
i.e., only
as part of the assertion made about the things occurring as
term.
In
the proposition
v. Russell is human (versus "Russell is
humane"?)
the person Russell (the man himself) occurs as term, but
humanity occurs
as concept. In the proposition
vi. Strawson
orbits Grice.
Strawson and Grice occur as term, and the relation of
orbiting occurs as
concept. Russell used "concept" for all those entities
capable of
occurring as concept — chiefly relations and other universals
— and
"thing" for
those entities such as Socrates, Callisto and
Jupiter, that can only
occur
as term. While Russell thought that only
certain entities were capable
of
occurring as concept, at the time,
he believed that every entity was
capable of occurring as term in a
proposition. In the proposition
vii. Gluttony is a big
vice.
the concept gluttony occurs as term. His argument that this held
generally
was that if there were some entity, E, that could not occur
as term,
there would have to be a fact, i.e., a true proposition, to
this
effect.
However, in the proposition E cannot occur as term in a
proposition, E
occurs
as term. Russell's account of propositions as
complexes of entities was
in
many ways in keeping with his views as
the nature of complexes and facts
during the core logical atomist
period. In particular, at both stages he
would regard the simple truth
that an individual a stands in the simple
relation R to an individual b
as a complex consisting of the individuals
a
and b and the relation
R. However, there are a number of positions
Russell
held in 1903
that were
abandoned in this later period; some of the more important were
these.
He
is committed to a special kind of propositional constituent
called a “
denoting concept”, involved in descriptive and quantified
propositions.
He
believes that there was such a complex, i.e., a
proposition, consisting
of
a, b and R even when it is not true that a
bears relation R to b. He
also
believes in the reality of classes,
understood as aggregate objects,
which could be constituents of
propositions. In each case, it is worth,
at least briefly, discussing
Russell's change of heart. Russell
expressed
the view that grammar is
a useful guide in understanding the make-up of
a proposition, and even
that in many cases, the make-up of a
proposition
corresponding to a
sentence can be understood by determining, for each
word of the
sentence, what entity in the proposition is meant by the
word.
Perhaps
in part because such phrases as "all dogs", "some numbers" and
"the
queen"appear as a grammatical unit, Russell came to the conclusion
that
they made a unified contribution to the corresponding proposition.
B
ecause Russell believed it impossible for a finite mind to grasp a
proposition of infinite complexity, however, Russell rejected a view
according to
which the (false) proposition designated by
viii.
All numbers are odd.
actually contains all numbers. Similarly,
although Russell admitted that
such a proposition as that is equivalent
to a formal implication, i.e.,
a
quantified conditional of the
form:
ix. (x)(x is a number ⊃ x is odd)
Russell held that
they are nevertheless distinct propositions. This was
perhaps in part due
to the difference in grammatical structure, and
perhaps also because the
former appears only to be about numbers,
whereas the
latter is about
all things, whether numbers or not. Instead, Russell
thought that the
proposition corresponding to the above contains as a
constituent the
denoting concept all numbers. Russell explained denoting
concepts
as
entities which, whenever they occur
in a proposition, the proposition is
not about them but about other
entities to which they bear a special
relation. So when the denoting
concept
all numbers occurs in a
proposition, the proposition is not about the
denoting concept, but
instead about 1 and 2 and 3, etc. Russell
abandons this
theory in
favour of his celebrated theory of definite and indefinite
descriptions.
What precisely lead Russell to become dissatisfied with
his
earlier
theory, and the precise nature of the argument he gave against
denoting
concepts (and similar entities such as Frege's senses), are a
matter
of great controversy, and have given rise to a large body of secondary
literature. It can merely be noted that Russell professed an inability
to
understand the logical form of propositions about denoting
concepts
themselves, as in the claim that "The present King of France is
a
denoting
concept". According to the new theory adopted, the
proposition expressed
by the
above was now identified with that
expressed by a quantified conditional
such as the formalised version.
Similarly, the proposition designated by
x. Some number is
odd.
was identified with the existentially quantified conjunction
represented
by
xi. (∃x)(x is a number & x is
odd)
Perhaps most notoriously, Russell argued that a proposition
involving a
definite description, e.g.,
xii. The King of France is
not bald.
was to be understood as having the structure of a certain
kind of
existential statement, in this case:
xiii. (∃x)(x is King
of France & (y)(y is King of France ⊃ x = y) & x
is
not
bald)
Russell cited in favor of these theories that they provided an
elegant
solution to certain philosophical puzzles. One involves how it is
that a
proposition can be meaningful even if it involves a description or
other
denoting phrase that does not denote anything. Given the above
account of
the
structure of the proposition expressed by "the King of
France is bald",
while France and the relation of being King of are
constituents, there
is no
constituent directly corresponding to the
whole phrase "the King of
France". The proposition in question is
false, since there is no value
of x
which would make it true. One is
not committed to a nonexistent entity
such as the King of France simply
in order to understand the make-up of
the
proposition. Russell's
theory provides an answer to how it is that
certain identity statements
can be both true and informative. On the
above
theory, the
proposition corresponding to:
xiv. The author of Waverly =
Scott
would be understood as having the following
structure:
xv. (∃x)(x authored Waverly & (y)(y authored Waverly ⊃ x
= y) & x =
Scott)
If instead, the proposition corresponding to
the above was simply a
complex consisting of the relation of identity,
Scott, and the author of
Waverly himself, since the author of Waverly
simply is Scott, the
proposition
would be the same as the
uninformative proposition
xvi. Scott = Scott.
(but, as Grice
said, "What conversational POINT could THAT have?") By
showing that the
actual structure of the proposition is quite a bit
different
from
what it appears from the grammar of the sentence
xiv. The author of
Waverly = Scott.
Russell believed he had shown how it might be more
informative (or
'stronger' as Grice prefers -- The Causal Theory of
Perception, 1961,
repr. in
WoW, Way of Words) than a trivial
instance of the law of identity, which
intelligent people like Grice
or Russell are supposed to KNOW already.
The
theory did away with
Russell's temptation to regard grammar as a very
reliable guide towards
understanding the structure or make-up of a
proposition. Especially
important in this regard is the notion of an “
incomplete
symbol”, by
which Russell understood an expression that can be
meaningful
in the
context of its use within a sentence, but does not by itself
correspond
to a constituent or unified part of the corresponding
proposition.
According to Russell's theory, phrases such as "the King of France," or
"the
author of the Waverly novels" were to be understood as incomplete
symbols
in this way. The general notion of an incomplete symbol was
applied by
Russell in ways beyond the theory of descriptions, and
perhaps most
importantly, to his understanding of classes. Russell
postulates two
types of
composite entities: unities and aggregates.
By a unity Russell meant a
complex entity in which the constituent parts
are arranged with a
definite
structure. A proposition was understood
to be a unity in this sense. By
an
aggregate, Russell means an
entity such as a class whose identity
conditions
are governed
entirely by what members or parts it has, and not by any
relationships
between the parts. By the time of the publication, with
Whitehead, of
Principia Mathematica Russell's views about both types of
composite
entities had changed drastically.Russell fundamentally
conceived of a
class as the extension of a concept, or as the extension of a
propositional function. Indeed, in The Principles of Mathematics he
claims that a
class may be defined as all the terms satisfying some
propositional
function.
However, Russell was aware already at the
time of POM that the
supposition there is always a class, understood as
an individual
entity, as the
extension of every propositional
function, leads to certain logical
paradoxes. Perhaps the most famous,
now called Russell's paradox, derived
from
consideration of the
class, w, of all classes not members of themselves.
The class w would
be a member of itself if it satisfied its defining
condition, i.e., if
it were not a member of itself. (Grice was to joke
on this
calling
Austin's Play Group, to which he belonged, as "the class of
tutors that
have no other class"). Similarly, w would not be a member of
itself
if it did not satisfy its defining condition, i.e., if it were a member
of itself. Hence, both the assumption that it is a member of itself, and
the assumption that it is not, are impossible. Another related paradox
Russell often discussed in this regard has since come to be called
Cantor's
paradox. Cantor had proven that if a class had n members,
that the
number
of sub-classes that can be taken from that class is
2n, and also that
2n >
n, even
when n is infinite. It follows
from this that the number of subclasses
of
the class of all
individuals, i.e., the number of different classes of
individuals, is
greater than the number of individuals.
Russell took this as strong
evidence that a class of individuals could
not itself be considered an
individual. Likewise, the number of
subclasses
of the class of all
classes is greater than the number of members in
the
class of all
classes. This Russell took to be evidence that there is
some
ambiguity in the notion of a class so that the subclasses of the class
of
all classes would not themselves be among its members, as it
would
seem.
Russell spent some time searching for a philosophically
motivated
solution
to such paradoxes. He tried solutions of various
sorts. However, after
the discovery of the theory of descriptions,
Russell becomes convinced
that
an expression for a class is an
incomplete symbol, i.e., that while
such
an expression can occur as
part of a meaningful sentence, it should not
be regarded as representing
a single entity in the corresponding
proposition. Russell dubbed this
approach the no-classes theory of
classes
because, while it allows
discourse about classes to be meaningful, it
does not
posit classes
as among the fundamental ontological furniture of the
world.
The
precise nature of Russell's no-classes theory underwent significant
changes.
However, in the version adopted in the first edition
of Principia
Mathematica, Whitehead and Russell believed that a
statement apparently
about a
class could always be reconstructed,
using higher-order quantification,
in terms of a statement involving its
defining propositional function.
Russell believed that whenever a class
term of the form
xv. {z|ψz}
appeared in some sentence, the
sentence as a whole could be regarded as
defined as follows:
xvi.
f({z|ψz}) =df (∃φ)((x)(φ!x ≡ ψx) & f(φ))
The above view can
be paraphrased, somewhat crudely, as the claim that
any truth seemingly
about a class can be reduced to a claim about some
or
all of its
members. It follows from this contextual definition of class
terms that
the statement to the effect that one class A is a subset of
another
class B is equivalent to the claim that whatever satisfies the
defining
propositional function of A also satisfies the defining
propositional
function of B. Russell also sometimes described this as the view that
classes are logical constructions, not part of the real world, but only
the
world of logic (This irritated Grice -- and Hart, "A logician's
fairy
tale"). Another way Russell expressed himself is by saying that a
class
is a
logical FICTION, an expression he borrowed from Bentham,
but never
returned. While it may seem that a class term is representative
of an
entity,
according to Russell, class terms are meaningful in a
different way.
Classes are not among the basic stuff of the world; yet
it is possible
to
make use of class terms in significant speech, as if
there were such
things as classes.
A class is thus portrayed by
Russell as a mere façon de parler, or
convenient way of speaking about
all or some of the entities satisfying
some
propositional function.
During the period in which Russell was working
on
Principia
Mathematica,
Russell also radically revised his former realism about
propositions
understood as mind independent complexes. The motivations
for the change
are
a matter of some controversy, but there are at
least two possible
sources. The first is that in addition to the logical
paradoxes
concerning the
existence of classes, Russell was aware of
certain paradoxes stemming
from
the assumption that propositions
could be understood as individual
entities. By Cantor's theorem, there
must be more classes of
propositions than
propositions. However, for
every class of propositions, m, it is
possible to generate a distinct
proposition, such as the proposition
that every
proposition in m is
true, in violation of Cantor's theorem.
Unlike the other paradoxes
mentioned above, a version of this paradox
can
be reformulated even if
talk of classes is replaced by talk of their
defining propositional
functions.
Russell was also aware of certain contingent paradoxes
involving
propositions, such as the Liar paradox formulated involving a
person S,
whose only
assertion at time t is the proposition All
propositions asserted by S at
time t are false. Given the success of the
rejection of classes as
ultimate
entities in resolving the paradoxes
of classes, Russell was motivated to
see if a similar solution to these
paradoxes could be had by rejecting
propositions as singular entities.
Another set of considerations pushing
Russell towards the rejection of
his former view of propositions is more
straightforwardly
metaphysical. According to his earlier view, and that
of
Moore, a
proposition was understood as a mind independent complex.
The
constituents of the complex are the actual entities involved, and
hence,
as we have seen, when a proposition is true, it is the same entity
as a
fact or state of affairs. However, because some propositions are false,
this view of propositions posits objective falsehoods. The false
proposition that
xvii. Venus orbits Neptune.
is thought to
be a complex containing Venus and Neptune the planets, as
well as the
relation of orbiting, with the relation occurring as a
relation,
i.e.,
as relating Venus to Neptune. However, it seems natural to suppose
that
the relation of orbiting could only unite Venus and Neptune into a
complex, if in fact, Venus orbits Neptune.
Hence, the presence of
such falsehoods is itself out of sorts with
common
sense.
Worse, as Russell explained, positing the existence of objective
falsehoods in addition to objective truths makes the difference between
truth and
falsehood inexplicable, as both become irreducible
properties of
propositions, and we are left without an explanation for
the privileged
metaphysical
status of truth over falsehood. Whatever
his primary motivation, Russell
abandons any commitment to objective
falsehoods, and restructured his
ontology of facts, and adopted a new
Tarski-type correspondence theory
of
truth (also endorsed by Grice
just to oppose Strawson's naive
performative
'ditto' theory of
'true').
In the terminology of the new theory, "proposition" was used
not for an
objective metaphysical complex, but simply for an interpreted
declarative
sentence, an item of language. Propositions are thought to
be true or
false
depending on their correspondence, or lack thereof,
with facts. In the
Introduction to Principia Mathematica, as part of his
explanation of
ramified
type-theory, Whitehead Russell described
various notions of truth
applicable to different types of propositions of
different complexity.
Grice made fun of this when he used the
example
xviii. My neighbour's three-year-old child understands
Russell's Theory
of
Types.
("Unbelievable, but hardly
logically contradictory" -- the implicature
was that only Russell
understood his own theory of types). The simplest
propositions in the
language of Principia Mathematica are what Russell
there
called
“elementary propositions”, which take forms such as “a has
quality
q”
, “a has relation [in intension] R to b”, or “a and b and c stand in
relation S”. Such propositions consist of a simple predicate,
representing
either a quality or a relation, and a number of proper
names.
According to Russell, such a proposition is true when there is
a
corresponding fact or complex, composed of the entities named by the
predicate and
proper names related to each other in the appropriate
way. E.g.,
xix. a has relation R to b.
is true if there exists
a corresponding complex in which the entity a is
related by the relation R
to the entity b. If there is no corresponding
complex, then the
proposition is false. Russell dubbed the notion of
truth
applicable
to elementary propositions
first truth. This notion of truth serves as
the ground for a hierarchy of
different notions of truth applicable to
different types of propositions
depending on their complexity. A
proposition such as
xx. (x)(x has quality q).
which involves a
first-order quantifier, has (or lacks) second truth
depending on whether
its instances have first truth.
In this case
xx. (x)(x has
quality q)
would be true if every proposition got by replacing the "x"
in "x has
quality q" with the proper name of an individual has first
truth.
A proposition involving the simplest kind of second-order
quantifier,
i.e., a quantifier using a variable for predicative
propositional
functions of
the lowest type, would have or lack third
truth depending on whether its
allowable substitution instances have
second or lower truth.
Because any statement apparently about a class
of individuals involves
this
sort of higher-order quantification, the
truth or falsity of such a
proposition will ultimately depend on the
truth or falsity of various
elementary
propositions about its
members.
Although Russell did not use "logical atomism" in the
Introduction to
Principia Mathematica, in many ways it represents the
first work of
Whitehead's
and Russell's atomist period.
Whitehead and Russell there explicitly endorsed the view that the
universe
consists of objects having various qualities and standing
in various
relations.
Propositions that assert that an object has
a quality, or that multiple
objects stand in a certain relation, were
given a privileged place in
the
theory, and explanation was given as
to how more complicated truths,
including
truths about classes,
depend on the truth of such simple propositions.
Russell's work over
the next two decades consisted largely in refining
and
expanding
upon this picture of the world.
Although Russell changed his mind on
a great number of philosophical
issues throughout his career, one of the
most stable elements in his
views is
the endorsement of a certain
methodology for approaching philosophy.
Indeed, it could be argued to
be the most continuous and unifying feature
of Russell's
philosophical work.
Russell employed the methodology self-consciously,
and gave only slightly
differing descriptions of this methodology in
works throughout his
career.
Understanding this methodology is
particularly important for
understanding
his logical atomism, as well
as what he meant by “analysis”.
The methodology consists of a two
phase process.
The first phase is dubbed the analytic phase
(although it should be
noted
that sometimes Russell used "analysis”
for the whole procedure.
One begins with a certain theory, doctrine or
collection of beliefs which
is taken to be more or less correct, but
is taken to be in certain
regards
vague, imprecise, disunified,
overly complex or in some other way
confused
or puzzling.
The
aim in the first phase is to work backwards from these beliefs, taken
as a kind of data”, to a certain minimal stock of undefined concepts
and
general principles which might be thought to underlie the original
body
of
knowledge.
The second phase, which Russell described
as the constructive or
synthetic
phase, consists in rebuilding or
reconstructing the original body of
knowledge in terms of the results of
the first phase.
More specifically, in the synthetic phase, one
defines those elements of
the original conceptual framework and
vocabulary of the discipline in
terms of
the minimum vocabulary
identified in the first phrase, and derives or
deduces the main tenets of
the original theory from the basic principles
or
general truths one
arrives at after analysis.
As a result of such a process, the system
of beliefs with which one
began
takes on a new form in which
connections between various concepts it
uses
are made clear, the
logical interrelations between various theses of the
theory are
clarified, and vague or unclear aspects of the original
terminology
are eliminated.
Moreover, the procedure also provides
opportunities for the application
of
Occam's razor, as it calls
for the elimination of unnecessary or
redundant
aspects of a
theory.
Concepts or assumptions giving rise to paradoxes or conundrums
or other
problems within a theory are often found to be wholly
unnecessary or
capable
of being supplanted by something less
problematic.
Another advantage is that the procedure arranges its
results as a
deductive
system, and hence invites and facilitates the
discovery of new results.
Examples of this general procedure can be
found throughout Russell's
writings, and Russell also credits others with
having achieved similar
successes.
Russell's work in mathematical
logic provides perhaps the most obvious
example of his utilization of
such a procedure. It is also an excellent
example of Russell's contention
that analysis proceeds in stages.
Russell saw his own work as the next
step is a series of successes
beginning with the work of Cantor, Dedekind
and Weierstrass.
Prior to the work of these figures, mathematics
employed a number of
concepts,number, magnitude, series, limit, infinity,
function, continuity,
etc.,
without a full understanding of the
precise definition of each concept,
nor
how they related to one
another.
By introducing precise definitions of such notions, these
thinkers
exposed
ambiguities (e.g., such as with the word
"infinite"), revealed
interrelations between certain of them, and
eliminated dubious notions
that had
previously caused confusion and
paradoxes (such as those involved with
the notion
of an
infinitesimal).
Russell saw the next step forward in the analysis of
mathematics in the
work of Peano and his associates, who not only
attempted to explain how
many
mathematical notions could be
arithmetized, i.e., defined and proven in
terms of arithmetic, but had
also identified, in the case of arithmetic,
three
basic concepts
(zero, successor, and natural number) and five basic
principles (the
Peano axioms), from which the rest of arithmetic was
thought to be
derivable.
Russell described the next advance as taking place in
the work of Frege.
According to the conception of number found in
Frege, a number can be
regarded as an equivalence class consisting of
those classes whose
members can
be put in 1-1 correspondence with any
other member of the class.
According to Russell, this conception
allowed the primitives of Peano's
analysis to be defined fully in terms
of the notion of a class, along
with
other logical notions such as
identity, quantification, negation and the
conditional.
Similarly, Frege's work showed how the basic principles of Peano's
analysis could be derived from logical axioms alone.
However,
Frege's analysis was not in all ways successful, as the notion
of
a class or the extension of a concept which Frege included as a
logically
primitive notion lead to certain contradictions.
In
this regard, Russell saw his own analysis of mathematics (largely
developed independently from Frege) as an improvement, with its more
austere
analysis that eliminates even the notion of a class as a
primitive idea,
and
thereby eliminates the
contradictions.
When Grice delivered his lecture, "Definte descriptions in Russell and in
the vernacular" he was being polemical. He knew that he was regarded as the
'head' (as it were) of Oxford ordinary language philosophy, and Russell was
in the "Antipodes" (metaphorically). So, Grice's point was that even if
you are an Oxford ordinary philosopher (as his tutee Strawson was) you can
be
wrong. And Grice's place in the history of philosophy was, he thought,
to
identify this manoeuvre that simply ignored the distinction (which he
thought crucial) between implication and implicature. This he did via
'analysis'
of the conceptual type.
It was clearly a part of
Russell's view in that in conducting an analysis
of a domain such as
mathematics (for it is clear that definite
descriptions also occur
elsewhere), and reducing its primitive conceptual
apparatus and unproven
premises to a minimum, one is not merely reducing
the
vocabulary of a
certain theory, but also showing a way of reducing the
metaphysical
commitments of the theory.
In first showing that numbers such as 1, 2,
etc., could be defined in
terms
of classes of like cardinality, and
then showing how apparent discourse
about “classes” could be replaced by
higher-order quantification,
Russell
made it possible to see how it
is that there could be truths of
arithmetic
without presupposing that
the numbers constitute a special category of
abstract entity.
Numbers are placed in the category of “logical fictions” or “logical
constructions” along with all other classes.
Russell's work from
the period after the publication with Whitehead of
Principia Mathematica
shows applications of this general philosophical
approach to
non-mathematical domains.
In particular, his work over the next two
decades shows concern with the
attempt to provide analyses of the notions
of knowledge, space, time,
experience, matter and causation.
When
Russell applied his analytic methodology to sciences such as
physics,
again the goal was to arrive at a minimum vocabulary required for the
science in question, as well as a set of basic premises and general
truths from
which the rest of the science can be derived.
However, according to the views developed by Russell in the
mid-1910s,
many of the fundamental notions in physics were thought to be
analyzable
in
terms of particular sensations: i.e., bits of colour
(Russell predates
the
idea of 'fifty shades of grey' -- even though
he implicates that 'grey'
is "no
colour") auditory notes, or other
simple parts of sensation, and their
qualities and relations.
Russell called such sensations, when actually experienced, “sense”.
In
particular, Russell believed that the notion of a physical thing
could be
replaced, or analyzed in terms of, the notion of a series of
classes of
sensible particulars each bearing to one another certain
relations of
continuity,
resemblance, and perhaps certain other
relations relevant to the
formulation of the laws of
physics.
Other physical notions such as that of a point of space, or
an instance
of
time, could be conceived in terms of classes of
sensible particulars and
their spatial and temporal
relations.
Later, after abandoning the view that perception is
fundamentally
relational, and accepting a form of William James's neutral
monism,
Russell
similarly came to believe that the notion of a
conscious mind could be
analyzed in
terms of various percepts,
experiences and sensations related to each
other by psychological
laws.
Hence, Russell came to the view point, matter, instant, mind,
and the
like
could be discarded from the minimum vocabulary needed
for physics or
psychology.
Instead, such words could be
systematically translated into a language
only
containing words
representing certain qualities and relations between
sensible
particulars.
Throughout these analyses, Russell put into practice a
slogan he stated
as
follows.
Wherever possible, logical
constructions are to be substituted for
inferred
entities.
Rival philosophies that postulate an ego or mind as an
entity distinct
from its mental states involve inferring the existence of
an entity that
cannot
directly be found in experience.
Something similar can be said about philosophies that take matter to
be
an
entity distinct from sensible appearances, lying behind them
and inferred
from them.
Combining Russell's suggestions that talk
of minds or physical objects is
to be analyzed in terms of classes of
sensible particulars with his
general
view that classes are logical
fictions, results in the view that minds
and
physical objects too are
logical fictions, or not parts of the basic
building blocks of reality.
Instead, all truths about such purported
entities
turn out instead to
be analyzable as truths about sensible particulars
and
their relations
to one another.
This is in keeping with the general metaphysical
outlook of logical
atomism.
We also have here a fairly severe
application of Occam's razor.
The slogan was applied within his
analyses in mathematics as well.
Noting
that sometimes a series of
rational numbers converges towards a limit
which
is not itself
specifiable as a rational, some philosophers of mathematics
thought
that one should postulate an irrational number as a limit.
Russell
claimed that rather than postulating entities in such a case, an
irrational number should simply be defined as a class of rational
numbers
without a rational upper bound. Russell preferred to
reconstruct talk of
irrationals this way rather than infer or postulate
the existence of a
new
species of mathematical entity not already
known to exist.
Complaining that the method of postulating what we want
has the
advantages
of theft over honest toil.
In conducting
an analysis of mathematics, or indeed, of any other domain
of thought,
Russell was clear that although the results of analysis can
be
regarded as logical premises from which the original body of knowledge
can
in principle be derived, epistemologically speaking, the
pre-analyzed
beliefs are more fundamental.
For example, in
mathematics, a belief such as
xxi. 2 + 2 = 4.
is
epistemologically more certain, and psychologically easier to
understand
and accept, than many of the logical premises from which it is derived.
Indeed, Russell believed that the results obtained through the
process
of
analysis obtain their epistemic warrant inductively from
the evident
truth
of their logical consequences.
The reason
for accepting an axiom, as for accepting any other
proposition,
is
always largely inductive, namely that many propositions which are
nearly
indubitable can be deduced from it, and that no equally plausible
way is
known by which these propositions could be true if the axiom were false,
and
nothing which is plausibly false can be deduced from it.
It
is perhaps for these reasons that Russell believed that the process of
philosophical analysis should always begin with beliefs the truth
of which
are not in question, i.e., which are nearly
indubitable.
When Russell spoke about the general philosophical
methodology described
here, he usually had in mind applying the
process of analysis to an
entire
body of knowledge or set of data
(Cfr. Paul, "Is there a problem about
sense
data" and its attending
implicature: "No, in spite of Russell -- Grice
suggests that the
implicature is "RUSSELL is the problem.").
In fact, Russell advocated
usually to begin with the uncontroversial
doctrine of a certain science,
such as mathematics or physics, largely
because
he held that these
theories are the most likely to be true, or at least
nearly true, and
hence make the most appropriate place to begin the
process of
analysis.
Russell did on occasion also speak of analyzing a
particular proposition
of ordinary life. One example he gave is “There
are a number of people
in
this room at this moment”.
In
this case, the truth or falsity of this statement may seem obvious,
but
exactly what its truth would involve is rather obscure.
The
process of analysis in this case would consist in attempting to make
the
proposition clear by defining what it is for something to be a room,
for
something to be a person, for a person to be in a room, what a moment is,
etc.
In this case, it might seem that the ordinary language
statement is
sufficiently vague that there is likely no one precise or
unambiguous
proposition
that represents the correct analysis of the
proposition.
In a way, this is right.
However, this does not
mean that analysis would be worthless.
Russell was explicit that the
goal of analysis is not to unpack what is
psychologically intended by an
ordinary statement such as the previous
example, nor what a person would
be thinking when he or she utters it.
The point rather is simply to
begin with a certain obvious, but rough and
vague statement, and find
a replacement for it in a more precise,
unified,
and minimal
idiom.
On Russell's view, vagueness is a feature of language, not of
the world.
In vague language, there is no one-one relation between
propositions and
facts, so that a vague statement could be considered
verified by any one
of a
range of different facts.
However, in
a properly analyzed proposition, there is a clear isomorphism
between
the structure of the proposition and the structure of the fact
that
would make it true.
Hence a precise and analyzed proposition is
capable of being true in one
and only one way.
In analyzing a
proposition such as
xxii. There are a number of people in this room
at this moment.
one might obtain a precise statement which would
require for its truth
that
there is a certain class of sensible
particulars related to each other in
a very definite way constituting the
presence of a room, and certain
other
classes of sensible particulars
related to each other in ways
constituting
people, and that the
sensible particulars in the latter classes bear
certain definite
relations to those in the first class of particulars.
Obviously,
nothing like this is clearly in the mind of a person who would
ordinarily use the original expression.
It is clear to see in
this case that a very specific state of things is
required for the truth
of the analyzed proposition, and hence the truth
of
it
will be
far more doubtful than the truth of the vague assertion with
which
one began the process.
As Russell put the point, the point of
philosophy is to start with
something so simple as not to seem worth
stating, and to end with
something so
paradoxical that no one will
believe it.
As we have seen, the primary metaphysical thesis of
Russell's atomism is
the view that the world consists of many independent
entities that
exhibit
qualities and stand in relations to one
another.
On this picture, the simplest sort of fact or complex
consists either of
a
single individual or particular bearing a
quality, or a number of
individuals bearing a relation to one another.
Relations can be divided into various categories depending on how
many
relata they involve: a binary or dyadic relation involves two relata
(e.g., a
is to the left of b); a triadic relation (e.g., a is between
b and c)
involves three relata and so on.
Russell at times used
the word “relation” in a broad sense so as to
include qualities, which
could be considered as monadic relations, i.e.,
relations that only
involve one relatum.
The quality of being white, involved, e.g., in
the fact that a is white,
could then, in this broader sense, also be
considered a relation.
At the time of Principia Mathematica, complexes
in Russell's and
Whitehead's ontology were all described as taking the
form of n
individuals entering
into an n-adic relation.
We
will give, they write, the name of a complex to any such object as "a
in
the relation R to b" or "a having the quality q" or "a and b and c
standing in relation S."
Broadly speaking, a complex is anything
which occurs in the universe and
is
not simple.
Russell
believes that an elementary proposition consisting of a single
predicate
representing an n-place relation along with n names of
individuals is
true if it corresponds to a complex.
An elementary proposition is
false if there is no corresponding complex.
Russell there gave no
indication that he believed in any other sorts of
complexes or
truth-makers for any other sorts of propositions.
Indeed, he held that
a quantified proposition is made true not by a
single
complex, but
by many.
If φx is an elementary judgment it is true when it points to
a correspond
ing complex.
But (x).φx does not point to a single
corresponding complex.
Te corresponding complexes are as numerous as
the possible values of x.
Soon after Principia Mathematica, Russell
became convinced that this
picture -- which he shared with Whitehead --
was "too simplistic" ("to me
if not
to Whitehead, an otherwise
very smart professor").
Thus, in the “Philosophy of Logical Atomism”
lectures Russell described
a
more complicated framework.
In
the new terminology, an atomic fact is was introduced for the simplest
kind of fact, i.e., one in which n particulars enter into an n-adic
relation.
Russell uses "atomic proposition" for a proposition
consisting only of a
predicate for an n-place relation, along with n
proper names for
particulars.
Hence, such propositions could take
such forms as
“F(a)”, “R(a, b)”, “S(a, b, c)”
An atomic
proposition is true when it corresponds to a positive atomic
fact.
However, Russell no longer conceived of falsity as simply lacking a
corresponding fact.
Russell now believes that some facts are
negative, i.e., that if “R(a, b)”
is false, there is such a fact as a's
not bearing relation R to b.
Since the proposition “R(a, b)” is
affirmative, and the corresponding
fact is negative, “R(a, b)” is false,
and, equivalently, its negation “
not-R(a, b)” is true.
Russell's
rationale for endorsing negative facts was somewhat
complicated.
However, one might object that on his earlier view,
according to which “
R(a, b)” is false because it lacks a corresponding
complex, is only
plausible
if you suppose that it must be a fact that
there is not such a complex,
and
such a fact would itself seem to be
a negative fact.
Russell later abandoned the view that qualities and
relations can occur
in
a complex as themselves the relata to another
relation, as in priority
implies diversity.
Russell now held the
view that whenever a proposition apparently
involves
a relation or
quality occurring as logical subject, it is capable of
being
analyzed
into a form in which the relation or quality occurs
predicatively.
For example,
xxiii. Prriority implies diversity.
might
be analyzed as:
xxiv. (x)(y)(x is prior to y ⊃ x is not
y)
Russell uses "molecular proposition" for those propositions that
are
compounded using truth-function operators.
Examples would
include:
F(a) & R(a, b)” and “R(a, b) ∨ R(b, a)
According
to Russell, it is unnecessary to suppose that there exists any
special
sort of fact corresponding to molecular propositions.
The truth-value
of a molecular proposition could be entirely derivative
on
the
truth-values of its constituents.
Hence, if
xxv. F(a) &
R(a,b)
is true, ultimately it is made true by two atomic facts, the
fact that a
has property F and the fact that a bears R to b, and not by a
single
conjunctive fact.
However Russell's attitude with regard to
quantified propositions had
changed.
He no longer believed that
the truth of a general proposition could be
reduced simply to the facts
or complexes making its instances true.
Russell argued that the
truth of the general proposition “(x).R(x, b)”
could not consist entirely
of the various atomic facts that a bears R to
b, b
bears R to b,c
bears R to b, ….
It also requires the truth that there are no other
individuals besides
a,
b, c, etc., i.e., no other atomic facts of the
relevant form.
Hence, Russell concluded that there is a special
category of facts he
calls general facts that account for the truth of
quantified
propositions,
although he admitted a certain amount of
uncertainty as to their precise
nature.
Likewise, Russell also
posited existence facts, those facts
corresponding
to the truth of
existentially quantified propositions, such as
xxvi. (∃x)R(x,
b)
In the case of general and existence facts, Russell did not think
it
coherent to make distinctions between positive and negative facts.
Indeed, a negative general fact could simply be described as an
existence
fact, and a negative existence fact could be described as a
general
fact.
For example, the falsity of the general
proposition
xxvii. All birds fly.
amounts to the fact that
there exist birds that do not fly, and the
falsity
of the existential
proposition
xxviii. There are unicorns.
amounts to the general
fact that everything is not a unicorn.
Obviously, however, the truth
or falsity of a general or existence
proposition is not wholly
independent of its instances.
In addition to the sorts of facts
discussed above, Russell raised the
question as to whether a special sort
of fact is required corresponding
to
propositions that report a
belief, desire or other propositional
attitude.
Russell's views on
this matter changed over different periods, as his own
views regarding
the nature of judgment, belief and representation
matured.
Moreover, in some works he left it as a open question as to whether
one
need presuppose a distinct kind of logical form in these
cases.
At times, however, Russell believed that the fact that S
believes that a
bears R to b amounts to the holding of a multiple
relation in which S,
a,
R
and b are all relata.
At other
points, he considered more complicated analyses in which
beliefs
amount to the possession of certain psychological states bearing
causal
or
other relationships to the objects they are about, or the
tendencies of
believers to behave in certain ways.
Depending on
how such phenomena are analyzed, it is certainly not clear
that they
require any new species of fact.
Russell's use of "atomic fact", and
indeed the very title of “logical
atomism” suggest that the constituents
of atomic facts, the logical
atoms,
Russell spoke of, must be
regarded as utterly simple and devoid of
complexity.
In that
case, the particulars, qualities and relations making up atomic
facts
constitute the fundamental level of reality to which all other
aspects
of reality are ultimately reducible.
This attitude is confirmed
especially in Russell's early logical atomist
writings.
"The
philosophy I espouse is analytic, because it claims that one must
discover the simple elements of which complexes are composed, and that
complexes presuppose simples, whereas simples do not presuppose
complexes."
"I believe there are simple beings in the universe, and
that these beings
have relations in virtue of which complex beings are
composed."
"Any time a bears the relation R to b there is a complex "a
in relation R
to b.""
"You will note that this philosophy is
the philosophy of logical
atomism."
"Every simple entity is an
atom."
Elsewhere Russell speaks of “logical atomism” as involving the
view
that
you can get down in theory, if not in practice, to
ultimate simples, out
of
which the world is built, and that those
simples have a kind of reality
not belonging to anything
else.
However, it has been questioned whether Russell had sufficient
argumentation for thinking that there are such simple beings.
In
the abstract, there are two sorts of arguments Russell could have
given
for the existence of simples, a priori arguments, or empirical arguments
(cf. Pears 1985, 4ff).
An a priori argument might proceed from
the very understanding of
complexity: what is complex presupposes parts.
Russell wrote: "I confess it seems obvious to me (as it did Leibniz)
that
what is complex must be composed of simples, though the number of
constituents may be infinite."
However, if construed as an
argument, this does not seem very convincing.
It seems at least
logically possible that while a complex may have parts,
its parts
might themselves be complex, and their parts might also be
complex, and
so on, ad infinitum.
Indeed, Russell himself later came to admit that
one could not know
simply
on the basis of something being complex
that it must be composed of
simples.
Another sort of a priori
argument might stem from conceptions regarding
the nature of analysis.
As analysis proceeds, one reaches more primitive notions, and it might
be
thought that the process must terminate at a stage in which the
remaining
vocabulary is indefinable because the entities involved
are absolutely
simple, and hence, cannot be construed as logical
constructions built
out
of
anything more primitive.
Russell did at some points describe his logical atoms as reached at
"the
limit of analysis" or "the final residue in analysis".
However, even during the height of his logical atomist period,
Russell
admitted that it is possible that "analysis could go on forever",
and
that
complex things might be capable of analysis "ad
infinitum". Grice liked
that
when he thought he would write: "From
Genesis to Revelations: a new
foundations for metaphysics".
Unfortunately, it remained an
unpublication.
One might argue for
simples as the basis of an empirical argument; i.e.,
one might claim
to have completed the process of analysis and to have
reduced all sorts
of truths down to certain entities that can be known
in
some
way
or another to be simple. Russell is sometimes interpreted as having
reasoned in this way.
According to Russell's well known principle
of acquaintance in
epistemology, in order to understand a proposition,
one must be
acquainted
with the
meaning of every simple symbol
making it up.
Russell at times suggested that we are only directly
acquainted with
sense
data, and their properties and relations,
and perhaps with our own
selves.
It might be thought that these
entities are simple, and must constitute
the terminus of analysis.
However, Russell was explicit that sense data can themselves be
complex,
and that he knew of no reason to suppose that we cannot be
acquainted
with
a
complex without being aware that it is complex
and without being
acquainted
with its constituents.
Indeed,
Russell eventually came to the conclusion that nothing can ever
be
known to be simple.
While there is significant evidence that
Russell did believe in the
existence of simple entities in the early
phases of his logical atomist
period,
it is possible that,
uncharacteristically, he held this belief without
argumentation. In
admitting that it is possible that analysis could go
on
ad
infinitum, Russell claimed that "I do not think it is true, but it is a
thing
that one might argue, certainly".
In “Logical Atomism”,
Russell admits that "by greater logical skill,
the
need for assuming
them, i.e. simples, can be avoided.
This attitude may explain in
part why it is that at the outset of his
1918
lectures on logical
atomism, he claimed that the things he is going to
say
in those
lectures are mainly "my own personal opinions and I do not
claim
that
they are more than that". (He knew most people thought the opinions
were
Witters's).
It may have been that Russell was interested not so much
in establishing
definitively that there are any absolutely simple
entities, but rather
in
combating the widespread arguments of others
that the notion of a
simple,
independent entity is incoherent, and
only the whole of the universe is
fundamentally real.
According
to Russell, such attitudes are customarily traced to a wrong
view
about relations.
In arguing for the doctrine of "external
relations", Russell was
attempting simply to render a world of simple
entities coherent again.
As his career progressed, Russell becomes
more and more prone to
emphasize
that what is important for his
philosophical outlook is not absolute
simplicity, but only relative
simplicity.
Thus, in response to criticism about his notion of
simplicity, Russell
writes: "as for “abstract analysis in search of the
simple’ and
elemental,
that is a more important matter."
To
begin with, "simple" must NOT be taken in an absolute way.
"Simpler"
would be a better word.
Of course, Russell should be glad to reach
the absolutely simple, but he
did not believe that that is within his
capacity.
What he did maintain is that, whenever anything is complex,
out
knowledge
is advanced by discovering constituents of it, even if
these
constituents
themselves are still complex.
According to
Russell, analysis proceeds in stages.
When analysis shows the
terminology and presuppositions of one stage of
analysis to be definable,
or logically constructible, in terms of simpler
and
more basic
notions, this is a philosophical advance, even if these
notions
are
themselves further analyzable.
As Russell says, the only drawback to
a language which is not yet fully
analyzed is that in it, one cannot
speak of anything more fundamental
than
those objects, properties or
relations that are named at that level.
Russell summarized his
position as follows:
If the world is composed of simples — i.e., of
things, qualities and
relations that are devoid of structure — not only
all our knowledge but
all that
of omniscience could be expressed by
means of words denoting these
simples.
We could distinguish in the
world a stuff (to use William James's word)
and a structure.
The
stuff would consist of all the simples denoted by names, while the
structure would depend on relations and qualities for which our minimum
vocabulary would have words.
This conception can be applied without
assuming that there is anything
absolutely simple.
We can define
as relatively simple whatever we do not know to be
complex.
Results obtained using the concept of relative simplicity will still
be
true if complexity is afterward found, provided we have abstained from
asserting absolute simplicity.
At a given stage of analysis, a
certain class of sentences may be
labeled
as "atomic", even if the
facts corresponding to them cannot be regarded
as
built of
fundamental ontological atoms.
Thus, Russell's logical atomism is a
mere commitment to conceptual
analysis as a method coupled with a
rejection of idealistic monism,
rather than a
pretense to have
discovered the genuine metaphysical atoms (or
corpuscules,
since they
are divisible) making up the world of facts, or even the
belief
that
such a discovery is possible.
Indeed, Russell continued to use
"logical atomism" to describe his
philosophy in later years of his
career, during the period in which he
stressed
relative, not absolute
simplicity.
Another important issue often discussed in connection
with logical
atomism
worth discussing in greater detail is the
supposition that atomic
propositions are logically independent of each
other, or that the truth
or falsity
of any one atomic proposition
does not logically imply or necessitate
the
truth or falsity of any
other atomic proposition.
Russell writes:
Perhaps one atomic
fact may sometimes be capable of being inferred from
another, though
Russell did not believe this to be the case; but in any
case
it
cannot be inferred from premises no one of which is an atomic
fact.
Thus Russell expresses doubt about the existence of any
relations of
logical dependence between atomic propositions, but the fact
that he
left
it as
a open possibility makes it seem that he would
not consider it a
defining
feature of an atomic proposition that it
must be independent from all
others, or a central tenet of logical
atomism generally that atomic
facts
are
independent from one
another.
Russell does often speak about the constituents of atomic
facts as
independently existing entities.
He writes for example
that each particular has its being independently
of
any other and
does not depend upon anything else for the logical
possibility
of its
existence.
One possible interpretation would be to take Russell as
holding that any
atomic fact involving a certain group of particulars
is logically
independent of an atomic fact involving a distinct group
of particulars,
even if the
two facts involve the same quality or
relation.
To use an example favoured by Grice (he used to ask his
children's
playmates):
Can a sweater be green and red all over? No
stripes allowed.
He was amused by how anti-corpuscularian his
children's playmates could
be.
The propositions
xxix. a is
red.
xxx. a is green.
do not seem to be independent from one
another: from the truth of one the
falsity of the other can seemingly
be inferred.
However, the weakened version of the independence
principle, on which
only
atomic facts involving different
particulars are independent, does not
entail that it is possible that "a
is red" and "a is green" may both be
true.
Russell saw himself as
denying the view that when a bears R to b, there
is
some part of a's
nature as an entity that involves its relatedness to b.
It might
be thought that Russell's doctrine of external relations
committed
him
at least to certain principles regarding the modal status of atomic
facts
(if not the independence principle).
According to certain ways of
defining the phrase, what it means for a
relation to be internal is that
it is a relation that its relata could
not fail
to have; an external
relation is one its relata could possibly not have.
Russell then
might be seen as committed to the view that atomic facts
(all
of
which involve particulars standing in relations, in the broad sense
above) are always contingent.
While this does not directly bear
on the question of their independence,
it would nevertheless commit
Russell to certain tenets regarding the
modal
features of atomic
facts.
Atomic propositions are of the simplest possible forms, and
there is
certainly nothing in their forms that would suggest any logical
connection to,
or incompatibility with, other atomic
propositions.
Perhaps the most illuminating remarks to be found in
Russell's work that
would lead one to expect complete logical independence
among ATOMIC
propositions involve the claims he made about how it is that
one
recognizes a
certain class of purported entities as “logical
constructions”, and the
recommendations he gives about analyzing
propositions involving them.
Prior to conceptual analysis, two
propositions may appear to be
logically
incompatible atomic
propositions.
However, Russell explains that the logical necessities
involved in cases such as these are due to the nature of material
objects, points and instants as logical constructions.
At a certain
point in time, a physical object might be regarded as a class of sensible
particulars bearing certain resemblance relations to one another
occupying a continuous region of space.
It is therefore impossible by
definition for the same physical object to occupy wholly distinct
locations at the same time.
When analyzed, such propositions
as:
xxxi. O1 is located at p1 at t1.
are revealed as having a
much more complicated logical form, and hence may have logical
consequences not evident before conceptual analysis.
We do not have here
any reason to think that truly atomic propositions, those containing
names of genuine particulars and their relations, are not always
independent.
Russell's logical atomism had significant influence on the
works of the logical positivist tradition, as exemplified in the works of
Ayer, whom Grice calls an 'infant terrible of Oxford philosophy'.
Grice confessed that, having been born "on the wrong side of the tracks" was never invited to the All Souls Play Group meetings on Thursday evenings that Ayer and Austin attended, and where they discussed "Russell
and cricket" ("not necessarily in that order").
Especially, the
notion of a “logical construction” was important for how such thinkers
conceived of the nature of ordinary objects, see, e.g., Ayer, or when Grice said:
xxxii. The self is a logical construction.
While
much of the work of the so-called “ordinary language” school of philosophy centered in Oxford in the 1940s and 1950s and beyond can also been seen largely as a critical response to views of Russell (see, e.g., Austin, 'Sense and Sensibilia', Warnock, 'Metaphysics in Logic', Urmson,
'Philosophical analysis), trust Grice to be an Oxonian dissident who
loved Russell ("in parts").
Abstracting away from Russell's
particular examples of proposed analyses in terms of sensible
particulars, the general framework of Russell's corpuscular picture of
the world, which consists of a plurality of entities that have
qualities and enter into relations, remains one to which many philosophers are attracted.
