To address the question posed in the title, I focus on Heidegger's conception of linguistic communication developed in the sections on Rede and Gerede of Being and Time. On the basis of a detailed analysis of these sections I argue that Heidegger was a social externalist but semantic internalist. To make this claim, however, I first need to clarify some key points that have led critics to assume Heidegger's commitment to social externalism automatically commits him to semantic externalism regarding concept (...) use. I begin by explaining the independence of those positions, arguing that social externalism answers the question of whose concepts in a linguistic community are properly individuated, whereas semantic externalism makes a claim about what it takes for concepts to be properly individuated. Once these issues are distinguished, it is possible to see that Heidegger's intersubjectivist conception of language commits him to social externalism, while his conception of the ontological difference commits him to semantic internalism.

The structure of this article is very simple. In the first half, I will introduce a sophisticated way of reading Heidegger as a relativist; I draw here on the work of Kusch and Lafont. In the second half, I present the counter-argument. As I see it, Heidegger is not a relativist; but understanding the relations between his approach and a relativistic one is crucial for an evaluation of both his own work and the broader trajectory of post-Kantian thought.

This paper argues that Tugendhat's critique of Heidegger's existential conception of truth as disclosedness is usually misunderstood. The main claim of this paper is that Tugendhat insists against Heidegger on certain conventional features of truth such as conformity of the law of non-contradiction, not because he adheres to an ideal of truth as correctness; rather, he proposes an alternative existential conception of truth in terms of an active, critical or self-critical, engagement with untruth. Various recent objections to Tugendhat's critique of (...) Heidegger are discussed against the background of his alternative and are rejected. The paper concludes by outlining several challenges to Tugendhat's alternative existential conception of truth. (shrink)
