Myro's System G

Speranza

In PGRICE, Myro presents Grice with a system G.

Grice was meant to provide individual responses to each of the contributions to the festschrift, but he had things to do (other than that).

Myro echoes Grice.

In "Words and Objections", Grice had introduced a system Q, to allow for things like the self-identity of

Pegasus = Pegasus

"Vacuous Names".

Myro, in "Time and Identity", in PGRICE, provides his System G ("in gratitude to Paul Grice"). In this system

=

becomes relativised to time.

The idea is to formalise the Hobbes paradox of the ship, and Aristotle's examples of the statue.

The result is too complex that does not fail to show Myro's expertise in logic that Grice had recognised in a footnote to "Vacuous Names". "I owe", Grice says -- paraphrasing him, "all I'm writing in formal logical terms here to Mates's "Logic" (Clarendon Press) and to George Myro".
