The author explores what he have managed to understand of the general features and trend of recent philosophy in Cambridge, that is, of the later doctrines of Wittgenstein and of those who have come under his influence. The most important fact about recent Cambridge philosophy is that it is a philosophy of language: it is an attempt to throw light on the linguistic framework by which we measure everything, and through which we deal with everything. The primary emphasis of modern Cambridge philosophy is on the use of words. Philosophy arises, in part, out of our confused wonder at the queer suggestions of linguistic expressions whose use has been forgotten. The author may also derive from the theory of language in question a new conception of the task of the philosopher which is quite as lofty in its way as the traditional Platonic or Hegelian picture.
