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 powe… - C. D. Broad

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.

It is true that our everyday view of the world is not quite naively realistic, but that is what it would like to be. Common-sense is naively realistic wherever it does not think that there is some positive reason why it should cease to be so. And this is so in the vast majority of its perceptions. When we see a tree we think that it is really green and really waving about in precisely the same way as it appears to be. We do not think of our object of perception being 'like' the real tree, we think that what we perceive is the tree, and that it is just the same at a given moment whether it be perceived or not, except that what we perceive may be only a part of the real tree.

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.
