On Operator N and Wittgenstein’s Logical Philosophy

Volume 5.4 of The Journal for the History of Analytical Philosophy is now online.

It features an article by James R. Connelly entitled, “On Operator N and Wittgenstein’s Logical Philosophy”. Here is an abstract.

In this paper, I provide a new reading of Wittgenstein’s N operator, and of its significance within his early logical philosophy. I thereby aim to resolve a longstanding scholarly controversy concerning the expressive completeness of N. Within the debate between Fogelin and Geach in particular, an apparent dilemma emerged to the effect that we must either concede Fogelin’s claim that N is expressively incomplete, or reject certain fundamental tenets within Wittgenstein’s logical philosophy. Despite their various points of disagreement, however, Fogelin and Geach nevertheless share several common and problematic assumptions regarding Wittgenstein’s logical philosophy, and it is these mistaken assumptions which are the source of the dilemma. Once we recognize and correct these, and other, associated expository errors, it will become clear how to reconcile the expressive completeness of Wittgenstein’s N operator, with several commonly recognized features of, and fundamental theses within, the Tractarian logical system.

The issue also contains a review of Sebastian Sunday Grève and Jakub Mácha, eds. Wittgenstein and the Creativity of Language, written by Craig Fox.
