It can be shown that a mathematical web of some kind can be woven about any universe containing several objects. The fact that our universe lends itself to mathematical treatment is not a fact of any great philosophical significance.

There is no nonsense so errant that it cannot be made the creed of the vast majority by adequate governmental action.

The whole conception of a God is a conception derived from the ancient oriental despotisms. It is a conception quite unworthy of free men. We ought to stand up and look the world frankly in the face.

In all this vast universe the thing that appears to him of most importance is that he himself should be virtuous. It is a grave defect in certain forms of traditional religion that they have encouraged this particular kind of self-absorption.

Some people would rather die than think.

Only mathematics and mathematical logic can say as little as the physicist means to say.

Be scrupulously truthful, even if the truth is inconvenient, for it is more inconvenient when you try to conceal it.
