"The Truth of Logic and the Univocity of p"
Abstract:
The notion of an occurrence of a proposition in discourse is the subject of the following observation:
(O) A proposition may occur in discourse, now asserted, now unasserted, and yet be recognizably the same proposition.
I shall argue that the true significance of this observation is utterly distorted by Geach’s manner of construing of it — a construal widely known today as “the Frege-Geach point”. Though it serves as a basis for a contemporary understanding of logical form, strictly thought through, this way of construing (O) can be shown to lead to absurdity. I will further argue that a straightforward, undistorted, acceptance of (O) is the key to a genuine philosophical logic.
