The German physicist Heinrich Hertz played a decisive role for Wittgenstein's use of a unique philosophical method. Wittgenstein applied this method successfully to critical problems in logic and mathematics throughout his life. Logical paradoxes and foundational problems including those of mathematics were seen as pseudo-problems requiring clarity instead of solution. In effect, Wittgenstein's controversial response to David Hilbert and Kurt Gödel was deeply influenced by Hertz and can only be fully understood when seen in this context. To comprehend the arguments (...) against the metamathematical programme, and to appreciate how profoundly the philosophical method employed actually shaped the content of Wittgenstein's philosophy, it is necessary to make an intellectual biographical reconstruction of their philosophical framework, tracing the Hertzian elements in the early as well as in the later writings. In order to write Wittgenstein's biography, we have to take seriously the coherence of his thought throughout his life, and not let convenient philosophical ideologies be our guidance in drawing up a “Wittgensteinian philosophy”. To do so, we have to take a second look upon what he actually wrote, not only in the already published material, but in the entire Nachlass. Clearly, this is not easily done, but it is a necessary task in the historical reconstruction of Wittgenstein's life and work. (shrink)

The aim of this paper is to show that a corollary of resolute readings of Wittgenstein’s conception of nonsense cannot be sustained. First, I describe the corollary. Next, I point out the relevance to it of Wittgenstein’s discussion of family resemblance concepts. Then, I survey some typical uses of nonsense to see what they bring to an ordinary language treatment of the word “nonsense” and its relatives. I will subsequently consider the objection, on behalf of a resolute reading, that “nonsense” (...) is a term of philosophical criticism. Finally, I conclude that resolute readings have not sufficiently accounted for how nonsense behaves in our language; they have failed to heed Wittgenstein’s warning: “don’t think, but look!”.

According to a widespread interpretation, in the Investigations Wittgenstein adopted a deflationary or redundancy theory of truth. On this view, Wittgenstein’s pronouncements about truth should be understood in the light of his invocation of the equivalences ‘p’ is true = p and ‘p’ is false = not p. This paper shows that this interpretation does not do justice to Wittgenstein’s thoughts. I will be claiming that, in fact, in his second book Wittgenstein is returning to the pre-Tractarian notion of bipolarity, (...) and that his new development of this notion in the Investigations excludes the redundancy-deflationary reading. Wittgenstein’s thoughts about truth are instead compatible with another interpretative option: Wittgenstein remains faithful to his methodological pronouncements, and he merely presents us with platitudes about the notions of “true” and “false”.

Seeing aspects is a dominant theme in Wittgenstein's 1940s writings on philosophy of psychology. Interpreters disagree about what Wittgenstein was trying to do in these discussions. I argue that interpreting Wittgenstein's observations about the interrelations between “noticing an aspect” and other psychological concepts as a systematic theory of aspect‐seeing diminishes key lessons of Wittgenstein's explorations: these interrelations are enormously complicated and “noticing an aspect” resists neat classification. Further, Wittgenstein invites us to engage in his “placing activity,” and by doing so (...) we are building a skill that is valuable for enabling us to help ourselves when we encounter conceptual difficulties.

An account of the norms of assertion is proposed which is supported by the same considerations that motivate the familiar knowledge account of those norms, but does not have a problematic consequence of the latter. This alternative account is defended against others to be found in the literature, and some larger epistemological issues it raises are considered briefly.

This thesis investigates the continuity of Wittgenstein’s approach to, and conception of, philosophy. Part One examines the rule-following passages of the Philosophical Investigations. I argue that Wittgenstein’s remarks can only be read as interesting and coherent if we see him, as urged by prominent commentators, resisting the possibility of a certain ‘sideways-on’ perspective. There is real difficulty, however, in ascertaining what the resulting Wittgensteinian position is: whether it is position structurally analogous with Kant’s distinction between empirical realism and transcendental idealism, (...) or whether philosophical ‘therapy’ is meant to dissolve any drive towards such idealism. I argue that both of these readings of Wittgenstein are found in the work of McDowell. Part Two argues that related issues arise in respect to the Tractatus Logico-Philosophicus and the question of realism. In the Tractatus Wittgenstein rejects the possibility of a certain ‘sideways-on’ perspective. Again, I argue, it is unclear whether Wittgenstein embraces a form of transcendental idealism or, on the contrary, ultimately reveals the idealist position to be empty. Part Three connects ‘sideways-on’ glances with the threat of idealism by introducing a philosophical ‘measure’. I argue that the measure is a useful tool in assessment of the Tractatus, and shows that Wittgenstein was no idealist, but is less useful as an assessment of the Investigations. It yields the result that Wittgenstein succumbed to idealism, but in doing so may overlook the ‘therapeutic’ nature of Wittgenstein’s later philosophy. (shrink)
