Georg Henrik von Wright
(Basil Blackwell, Oxford: 1982)
Wittgenstein had done no systematic reading in the classics of philosophy. He could read only what he could wholeheartedly assimilate. We have seen that as a young man he read Schopenhauer. From Spinoza, Hume, and Kant he said that he could only get occasional glimpses of understanding. I do not think that he could have enjoyed Aristotle or Leibniz, two great logicians before him. But it is significant that he did read and enjoy Plato. He must have recognized congenial features, both in Plato's literary and philosophical method and in the temperament behind the thoughts.
