A man is rational in proportion as his intelligence informs and controls his desires. - Bertrand Russell

It is the duty of all who care for their country or for civilisation to point out that we cannot further any of our ideals by participation in the next war, and that we ought therefore to resist all measures based upon the assumption that we shall take part in it. In the late war it was arguable that victory, being possible, might do some good. With the modern technique of gas attack, no belligerent can hope for victory. Absolute pacifism, therefore, in every country, in which it is politically possible, is the only sane policy both for Governments and individuals.

All serious innovation is only rendered possible by some accident
enabling unpopular persons to survive.

All human activity is prompted by desire. There is a wholly fallacious theory advanced by some earnest moralists to the effect that it is possible to resist desire in the interests of duty and moral principle. I say this is fallacious, not because no man ever acts from a sense of duty, but because duty has no hold on him unless he desires to be dutiful. If you wish to know what men will do, you must know not only, or principally, their material circumstances, but rather the whole system of their desires with their relative strengths.
