"It is to be feared that Spinoza would not have been enlightened enough to appreciate the beneficient system of the Ph.D. degree, introduced into English universities as a measure of post-war propaganda, whereby the time and energy of those who are qualified to do research are expended in supervising the work of those who never will be."

“There is no important problem in any branch of philosophy which is not treated by Kant, and he never treated a problem without saying something illuminating and original about it. He was certainly wrong on many points of detail, and he may well be wrong in his fundamental principles; but, when all criticisms have been made, it seems to me that Kant’s failures are more important than most men’s successes.”

“There certainly are changes of fashion in philosophy. When a new kind is in vogue, many things in the philosophy of an earlier day, which are of permanent value and perhaps highly relevant to contemporary problems, tend to be altogether forgotten or carelessly and ignorantly dismissed, simply because they occur in an out-of-date setting and are clad in an unfashionable dress. It is now quite certain that much of permanent value in Scholastic philosophy was ignored or contemned from this cause by Locke, Berkeley, Hume, and their followers. I have little doubt that the same is true mutatis mutandis of the attitude of many present-day philosophers towards the systems of monistic idealism which were fashionable at the beginning of this century. It is consoling to a philosopher's vanity not to pry too closely into the history of his subject, for otherwise he is liable to find that his discoveries have been anticipated and his fallacies refuted in advance by predecessors whom he has ignored or despised.”

“I understand that it is the wish of the Editor of this collection of essays that each contributor should describe his own system of philosophy. Were I to interpret this demand literally I could not contribute anything at all, for two excellent reasons. In the first place, I have nothing worth calling a system of philosophy of my own, and there is no other philosopher of whom I should be willing to reckon myself a faithful follower. If this be a defect I see no likelihood of its ever being cured. Secondly, if I had a system of my own, I should doubt the propriety of "pushing" my crude philosophical wares in competition with the excellent products of older firms with well-earned reputations.”

“Take an eighteenth century English whig. Let him be a mystic. Endow him with the logical subtlety of the great schoolmen and their belief in the powers of human reason, with the business capacity of a successful lawyer, and with the lucidity of the best type of French mathematician. Inspire him in his early youth with a passion for Hegel. Then subject him to the teaching of Sidgwick and the continual influence of Moore and Russell. Set him to expound Hegel. What will be the result? Hegel himself could not have answered this question a priori, but the course of world history has solved it ambulando by producing McTaggart.”

“If Hegel be the inspired and too often incoherent prophet of the Absolute, if Bradley be its chivalrous knight, McTaggart is its devoted and extremely acute family solicitor.”

“Although people cannot define existence and do use the term with some looseness, yet it is possible to give an extensive definition by pointing to the sorts of things that everyone believes to exist. It is still easier to point to the sort of entities that people agree in believing not to exist, and happily, this is really what concerns us most. People mean by saying that causation only applies to things that exist that it applies, if at all, to what can change; and they believe that, if anything can change, it is things like chairs and tables and minds, and not those like the propositions of Euclid and the multiplication table. What would be agreed then is that, if causal laws apply to anything it is to what can change in so far as it changes.”
