He [Spinoza] believes in authority. And, of course, he believed in freedom of thought and expression, whereas Hobbes does not. There is a book on Spinoza written by an American ex-Marxist, called Spinoza and the Rise of Liberalism, on these lines. But Spinoza is not a theorist in whom I am particularly interested, because he is too rationalistic for me. But the Ethics is a wonderful book, and full of deep insights and noble feeling. It is totally unhistorical: the idea of timeless truths about human beings seems suspect to me.
