In Morris I presented in outline a new interpretation of the famous ‘substance argument’ in Wittgenstein’s Tractatus. The account I presented there gave a distinctive view of Wittgenstein’s main concerns in the argument, but did not explain in detail how the argument works: how its steps are to be found in the text, and how it concludes. I remain convinced that the interpretation I proposed correctly identifies the main concerns which lie behind the argument. I return to the argument here (...) in order to elaborate in fuller detail the relation between those concerns and the actual course of the text. (shrink)

Wittgenstein did not write very much on the topic of probability. The little we have comes from a few short pages of the Tractatus, some 'remarks' from the 1930s, and the informal conversations which went on during that decade with the Vienna Circle. Nevertheless, Wittgenstein's views were highly influential in the later development of the logical theory of probability. This paper will attempt to clarify and defend Wittgenstein's conception of probability against some oft-cited criticisms that stem from a misunderstanding of (...) his views. Max Black, for instance, criticises Wittgenstein for formulating a theory of probability that is capable of being used only against the backdrop of the ideal language of the Tractatus. I argue that on the contrary, by appealing to the 'hypothetical laws of nature', Wittgenstein is able to make sense of probability statements involving propositions that have not been completely analysed. G.H. von Wright criticises Wittgenstein's characterisation of these very hypothetical laws. He argues that by introducing them Wittgenstein makes what is distinctive about his theory superfluous, for the hypothetical laws are directly inspired by statistical observations and hence these observations indirectly determine the mechanism by which the logical theory of probability operates. I argue that this is not the case at all, and that while statistical observations play a part in the formation of the hypothetical laws, these observations are only necessary, but not sufficient conditions for the introduction of these hypotheses.

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.

Wittgenstein likened himself to a soil distinctive only in that once implanted with the seeds of great thinkers, interesting flora grew. This chapter examines the influence on him of authors he regarded as truly original, such as Bolzmann, Hertz, Schopenhauer, Frege and Russell.
