“The only kind of appeal that wins any instinctive response in party politics is an appeal to hostile feeling; the men who perceive the need of cooperation are powerless. Until education has been directed for a generation into new channels, and the Press has abandoned incitements to hatred, only harmful policies have any chance of being adopted in practice by our present political methods. But there is no obvious means of altering education and the Press until our political system is altered. From this dilemma there is no issue by means of ordinary action, at any rate for a long time to come. The best that can be hoped, it seems to me, is that we should, as many of us as possible, become political skeptics, rigidly abstaining from belief in the various attractive party programmes that are put before us from time to time.”

“Most men think that in framing their political opinions they are actuated by desire for the public good; but 9 times out of 10 a man’s politics can be predicted from the way in which he makes a living. This has led some people to maintain, and many more to believe practically, that in such matters it is impossible to be objective, and that no method is possible except a tug-of-war between classes with opposite bias.”

“Religious toleration, to a certain extent, has been won, because people have ceased to consider religion so important as it was once thought to be. But in politics and economics, which have taken the place formerly occupied by religion, there is a growing tendency to persecution, which is not by any means confined to one party.”

“I think the subject which will be of most importance politically is Mass Psychology... Its importance has been enormously increased by the growth of modern methods of propaganda. Although this science will be diligently studied, it will be rigidly confined to the governing class. The populace will not be allowed to know how its convictions are generated.”

“Those who have a scientific outlook on human behaviour, moreover, find it impossible to label any action as ‘sin’; they realise that what we do has its origin in our heredity, our education, and our environment, and that it is by control of these causes, rather than by denunciation, that conduct injurious to society is to be prevented.”

“The need of politeness is at its maximum in speaking with foreigners, and is so irksome as to be paralysing to those who are only accustomed to compatriots.”

“I have been accused of a habit of changing my opinions. I am not myself in any degree ashamed of having changed my opinions. What physicist who was already active in 1900 would dream of boasting that his opinions had not changed during the last half century? In science men change their opinions when new knowledge becomes available; but philosophy in the minds of many is assimilated rather to theology than to science. The kind of philosophy that I value and have endeavoured to pursue is scientific, in the sense that there is some definite knowledge to be obtained and that new discoveries can make the admission of former error inevitable to any candid mind. For what I have said, whether early or late, I do not claim the kind of truth which theologians claim for their creeds. I claim only, at best, that the opinion expressed was a sensible one to hold at the time when it was expressed. I should be much surprised if subsequent research did not show that it needed to be modified. I hope, therefore, that whoever uses this dictionary will not suppose the remarks which it quotes to be intended as pontifical pronouncements, but only as the best I could do at the time towards the promotion of clear and accurate thinking. Clarity, above all, has been my aim.”
