“Leibniz was somewhat mean about money. When any young lady at the court of Hanover married, he used to give her what he called a "wedding present," consisting of useful maxims, ending up with the advice not to give up washing now that she had secured a husband. History does not record whether the brides were grateful. ”

“Morality in sexual relations, when it is free from superstition, consists essentially in respect for the other person, and unwillingness to use that person solely as a means of personal gratification, without regard to his or her desires.”

“No man treats a motorcar as foolishly as he treats another human being. When the car will not go, he does not attribute its annoying behavior to sin; he does not say, 'You are a wicked motorcar, and I shall not give you any more petrol until you go.' He attempts to find out what is wrong and to set it right.”

“To all the talented young men who wander about feeling that there is nothing in the world for them to do, I should say: 'Give up trying to write, and, instead, try not to write. Go out into the world; become a pirate, a king in Borneo, a labourer in Soviet Russia; give yourself an existence in which the satisfaction of elementary physical needs will occupy almost all your energies.' I do not recommend this course of action to everyone, but only to those who suffer from the disease which Mr Krutch diagnoses. I believe that, after some years of such an existence, the ex-intellectual will fin that in spite of is efforts he can no longer refrain from writing, and when this time comes his writing will not seem to him futile.”

“The problem of the social reformer, therefore, is not merely to seek means of security, for if these means when found provide no deep satisfaction the security will be thrown away for the glory of adventure.”

“The extent to which beliefs are based upon evidence is very much less than believers suppose. Take the kind of action which is most nearly rational: the investment of money by a rich City man. You will often find that his view (say) on the question whether the French franc will go up or down depends upon his political sympathies, and yet is so strongly held that he is prepared to risk money on it.”

“The use of self control is like the use of brakes on train. It is useful when you find yourself in wrong direction but merely harmful when the direction is right”
