When I come to my own beliefs, I find myself quite unable to discern any purpose in the universe, and still more unable to wish to discern one. - Bertrand Russell

What does not exist must be something, or it would be meaningless to deny its existence; and hence we need the concept of being, as that which belongs even to the non-existent.

"I don't want to! Why should I?" "Because more people will be happier if you do than if you don't." "So what? I don't care about other people." "You should." "But why?" "Because more people will be happier if you do than if you don't."

It seems to me that science has a much greater likelihood of being true in the main than any philosophy hitherto advanced (I do not, of course, except my own). In science there are many matters about which people are agreed; in philosophy there are none. Therefore, although each proposition in a science may be false, and it is practically certain that there are some that are false, yet we shall be wise to build our philosophy upon science, because the risk of error in philosophy is pretty sure to be greater than in science. If we could hope for certainty in philosophy, the matter would be otherwise, but so far as I can see such a hope would be chimerical.
