In this article I offer a novel explanation of Wittgenstein’s claim, in his Tractatus, that to represent the logical form of a proposition would require our being positioned outside of logic. The account here presented aims to exploit a connection, widely noticed, between the logical forms of objects and those of the propositions in which the names of those objects figure. I show that the logical forms of propositions may, on Wittgenstein’s view, be identified with places in logical space, and (...) that places in logical space are reducible to the forms of both objects and their names. I argue, though, that according to Wittgenstein the representation of a proposition’s logical form would require the existence of a place in logical space not so reducible. I conclude that on Wittgenstein’s position, the attempt to represent logical forms cannot, therefore, succeed. (shrink)

The aim of this paper is to discuss Wittgenstein's conception of truth in the Tractatus Logico-Philosophicus. Section 1 sets the scene by exploring how the notion of truth is in the Tractatus intertwined with notions such as sense and picture. In section 2 I discuss a traditional interpretation that sees the Tractatus as committed to truth as correspondence. In sections 3 and 4 I discuss two more recent alternative lines of interpretation; according to one, we should interpret truth in the (...) Tractatus as a relation of identity. According to the other, the Tractatus endorses a deflationary account of truth. I conclude in section 5 by adjudicating the interpretative debate. (shrink)

Pragmatic theories of truth need to pass the pragmatic test: they need to make a difference. Unfortunately, defenders of the pragmatic theory have rarely applied this test. I argue that a Deweyan pragmatic account of truth passes the test by identifying the political and epistemic dangers of certain types of social networks that create a durable consensus around false beliefs. To better understand Dewey’s account of truth I propose an excursion through Wittgenstein’s later views on knowledge and certainty.

Truth is one of the central subjects in philosophy. It is also one of the largest. Truth has been a topic of discussion in its own right for thousands of years. Moreover, a huge variety of issues in philosophy relate to truth, either by relying on theses about truth, or implying theses about truth.
