"To speak seriously: the standards of "goodness" which are generally recognized by public opinion are not those which are calculated to make the world a happier place. This is due to a variety of causes, of which the chief is tradition, and the next most powerful is the unjust power of dominant classes."

My desire and wish is that the things I start with should be so obvious that you wonder why I spend my time stating them. This is what I aim at because the point of philosophy is to start with something so simple as not to seem worth stating, and to end with something so paradoxical that no one will believe it.

(on A History of Western Philosophy) I was sometimes accused by reviewers of writing not a true history but a biased account of the events that I arbitrarily chose to write of. But to my mind, a man without a bias cannot write interesting history - if, indeed, such man exists.
