Wittgenstein on Certainty

Abstract

Wittgenstein's book On Certainty which was first published in 1969, eighteen years after his death, is a collection of notes which he composed during the last eighteen months of his life. As his editors explain in their preface, these notes, which were written at four different periods, are all in the form of a first draft. They are more repetitive than they no doubt would have been if Wittgenstein had been able to revise them. Even so, they are characteristically succinct and penetrating, and the argument which they develop is easier to follow than that of the general run of Wittgenstein's later work.
