Grice's Modified Occam's Razor -- and why he needed it

Speranza

Well, because only accepting M. O. R., as Grice likes to abbreviate the thing, does it make sense to posit an implicatum.

But it is a meta-theoretical thing. And Grice, at least in "Logic and Conversation," is having P. F. Strawson's mistakes in mind (regarding "if").

The examples Grice gives in "Prolegomena" may apply, too.

Unfortunately, Strawson is too good of a Griceian tuttee to count. Strawson would say that 'and' and 'and then' are two USAGES (not 'senses') of the logician's ampersand, as used by Russell and Whitehead (or Whitehead and Russell) in "Principia Mathematica."
