• As a pianist, our particular role is to enter a piece and its logic and create a particular interpretation from our understanding.

• I believe in kindness and niceness and lots of spiritual things, but the real intellectual rigor and quest of logic is something that I'm afraid takes incredibly hard work and we live in an age in which hard work is if not actively deprecated or denigrated it is run away from or ignored.

• Slavery in America was perpetuated not merely by human badness but also by human blindness. ... Men convinced themselves that a system that was so economically profitable must be morally justifiable. ... Science was commandeered to prove the biological inferiority of the Negro. Even philosophical logic was manipulated [exemplified by] an Aristotlian syllogism:
  All men are made in the image of God;
  God, as everyone knows, is not a Negro;
  Therefore, the Negro is not a man.

• Logic, too, also rests on assumptions that do not correspond to anything in the real world, e.g., on the assumption that there areequal things, that the same thing is identical at different points in time: but this science arose as a result of the opposite belief (that such things actually exist in the real world). And it is the same with mathematics, which would certainly never have arisen if it had been understood from the beginning that there is no such thing in nature as a perfectly straight line, a true circle, and absolute measure.

• General scepticism is the live mental attitude of refusing to conclude. It is a permanent torpor of the will, renewing itself in detail towards each successive thesis that offers, and you can no more kill it off by logic than you can kill off obstinacy or practical joking.

• Scholars and artists thrown together are often annoyed at the puzzle of where they differ. Both work from knowledge; but I suspectthey differ most importantly in the way their knowledge is come by. Scholars get theirs with conscientious thoroughness along projected lines of logic; poets theirs cavalierly and as it happens in and out of books. They stick to nothing deliberately, but let what will stick to them like burrs where they walk in the fields.

• Logic, like language, is partly a free construction and partly a means of symbolizing and harnessing in expression the existing diversities of things; and whilst some languages, given a man's constitution and habits, may seem more beautiful and convenient to him than others, it is a foolish heat in a patriot to insist that only his native language is intelligible or right.

• Neither logic nor scientific evidence supports such a belief. Although spinal manipulation can relieve certain types of back pain, neck pain, and other musculoskeletal symptoms, there is no scientific evidence that it can restore or maintain health. As a result of expressing my opinion on this subject, I have been called a chiropractic heretic.

• The question of "unreality"is a very important one. Misled by grammar, the great majority of those logicians who have dealt with this question have dealt with it on mistaken lines. They have regarded grammatical form as a surer guide in analysis than, in fact, it is. And they have not known what differences in grammatical form are important.

• The difference between prose logic and poetic thought is simple. The logician uses words as a builder uses bricks, for the unemotional deadness of his academic prose; and is always coining newer, deader words with a natural preference for Greek formations. The poet avoids the entire vocabulary of logic unless for satiric purposes, and treats words as living creatures with a preference for those with long emotional histories dating from mediaeval times. Poetry at its purest is, indeed, a defiance of logic.
