It is an ancient view, to be found even in Aristotle’s analysis of friendship, that the other is an alter ego, another myself. More recently, this conception has provoked spirited debate within and without the phenomenological tradition. It can be found in a wide variety of texts, from Husserl’s Cartesian Meditations to Thomas Nagel’s “What is it like to be a bat?” The basic position can be summarized as follows. Intentional experiences are subjective, first-person experiences, not objective, third-person experiences.

This is a concise and readable study of five intertwined themes at the heart of Wittgenstein's thought, written by one of his most eminent interpreters. David Pears offers penetrating investigations and lucid explications of some of the most influential and yet puzzling writings of twentieth-century philosophy. He focuses on the idea of language as a picture of the world; the phenomenon of linguistic regularity; the famous "private language argument"; logical necessity; and ego and the self.

I start from Hans Sluga's paper “Truth before Tarski”, in which he argues that the establishing of Tarski's approach to truth brought loss as well as gain to analytic philosophy: what was lost was our understanding of the problem of truth. To recover what was lost, he says, we must examine the variety of pre‐Tarskian views. My paper picks up that task and focuses on Wittgenstein's Tractatus. I interweave ideas borrowed from Thomas Ricketts, P. T. Geach, Warren Goldfarb, Peter Hylton, (...) and Juliet Floyd, and thereby try to explain the relation between Wittgenstein's conception of sense and his view of truth. (shrink)
