When in May 1930, the Council of Trinity College, Cambridge, had to decide whether to renew Wittgenstein's research grant, it turned to Bertrand Russell for an assessment of the work Wittgenstein had been doing over the past year. His verdict: The theories contained in this new work. . . are novel, very original and indubitably important. Whether they are true, I do not know. As a logician who like simplicity, I should like to think that they are not, but from what I have read of them I am quite sure that he ought to have the opportunity to work them out, since, when completed, they may easily prove to constitute a whole new philosophy.

Ludwig Wittgenstein - 1889 - 1951 - was an Austrian-British philosopher who taught at the University of Cambridge and is known as one of the most important philosophers of the 20th century. He worked in the areas of logic and the philosophy of mathematics, the mind and language.

The majority of his writing was published after his death Rush Rhees was a pupil of Ludwig Wittgenstein and is one of his literary executors.
