This fourth and final volume of the monumental commentary on Wittgenstein's _Philosophical Investigations_ covers pp 428-693 of the book. Like the previous volumes, it consists of philosophical essays and exegesis.

In this country, we tend to look at Wittgenstein in a rather ahistorical way. We see his concerns as fundamentally logico-linguistic, following on first from the work of Frege and Russell, and then referring back indirectly to the concerns of the British empiricists, to those of Locke and Hume, say, on such matters as the reference of our talk about sensations and scepticism about the external world. Recently there has been considerable discussion of the extent to which Wittgenstein's own analysis (...) of the private language and of rule-following might not itself be a new version of a fundamentally Humean scepticism: according to Saul Kripke, Wittgenstein's arguments amount to a demonstration that there is no more reason for speakers of a language to follow the rules governing the concepts of that language in the same way than on the Humean account there is any reason for an effect to follow its causes.
