Man is a credulous animal, and must believe something; in the absence of good grounds for belief, he will be satisfied with bad ones. - Bertrand Russell

To understand the actual world as it is, not as we should wish it to be, is the beginning of wisdom.

The moral things I wish to say to future generations is very simple. I should say love is wise hatred is foolish. In this world which is getting more and more closely interconnected, we have to learn to tolerate each other. We have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way, and if we are to live together and not die together we must learn the kind of charity and kind of tolerance which is absolutely vital to the continuation of human life on this planet.

The people who are regarded as moral luminaries are those who forego ordinary pleasures themselves and find compensation in interfering with the pleasures of others.
