Contradiction

 Contradiction consists of a logical l incompatibility between two or more propositions. It occurs when the propositions, taken together, yield two conclusions which form the logical, usually opposite inversions of each other. By extension, outside of classical logic, one can speak of contradictions between actions when one presumes that their motives contradict each other.

 * A quarter of America is a dramatic, tense, violent country, exploding with contradictions, full of brutal, physiological vitality, and that is the America that I have really loved and love.

 * On the way to the wardrobe I thought I would dress in baggy pants, big shoes, and a cane and a derby hat. I wanted everything to be a contradiction; the pants baggy, the coat tight, the hat small and the shoes large. I was undecided whether to look young or old, but remembering Sennet had expected me to be a much older man, I added a small moustache, which I reasoned, would add age without hiding my expression.

 * ... one of the basic principles of higher mathematics is the contradiction that in certain circumstances straight lines and curves may be the same.... But even lower mathematics teems with contradictions.
 * Engels, in "Selected Works of Mao Tse-tung On Contradiction".


 * If simple mechanical change of place contains a contradiction, this is even more true of the higher forms of motion of matter, and especially of organic life and its development... life consists precisely and primarily in this--that a being is at each moment itself and yet something else. Life is therefore also a contradiction which is present in things and processes themselves, and which constantly originates and resolves itself; and as soon as the contradiction ceases, life, too, comes to an end, and death steps in. We likewise saw that also in the sphere of thought we could not escape contradictions, and that for example the contradiction between man's inherently unlimited capacity for knowledge and its actual presence only in men who are externally limited and possess limited cognition finds its solution in what is--at least practically, for us--an endless succession of generations, in infinite progress.
 * Engels, in "Selected Works of Mao Tse-tung On Contradiction".

 * Reason is man's faculty for grasping the world by thought, in contradiction to intelligence, which is man's ability to manipulate the world with the help of thought. Reason is man's instrument for arriving at the truth, intelligence is man's instrument for manipulating the world more successfully; the former is essentially human, the latter belongs to the animal part of man.

 * Gandhi addressed them thus when he had organized a very large march, and thousands of people came. After a while he noticed that it had the potential to become violent, so he gathered the people together and told them that he was calling the march off. There was anger. Many people had sacrificed a great deal to be there.

 * The prime requisite of a set of postulates is that it be consistent. Since the ordinary notion of consistency involves that of contradiction, which again involves negation, and since this function does not appear in general as a primitive in [the generalized set of postulates] a new definition must be given.

 * All skepticism is a kind of idealism. Hence when the skeptic Zeno pursued the study of skepticism by endeavoring existentially to keep himself unaffected by whatever happened, so that when once he had gone out of his way to avoid a mad dog, he shamefacedly admitted that even a skeptical philosopher is also sometimes a man, I find nothing ridiculous in this. There is no contradiction, and the comical always lies in a contradiction.

 * ...it is trite that contradictions per se do not lead to the rejection of a witness’s evidence and what the trier of fact has to take into consideration, are matters such as the nature of the contradictions; their number and importance, and their bearing on other parts of the witness’s evidence.

 * I'm fascinated by the ways in which people express themselves, because their responses are often counter to what they're actually feeling. Like when they're frightened, they tend to freeze.

 * . . . I in my astonishment said: What do you mean Dionysodorus? I have often heard, and have been amazed to hear, this thesis of yours, which is maintained and employed by the disciples of Protagoras and others before them, and which to me appears to be quite wonderful, and suicidal as well as destructive, and I think that I am most likely to hear the truth about it from you. The dictum is that there is no such thing as a falsehood; a man must either say what is true or say nothing. Is not that your position?

 * Ever since Plato most philosophers have considered it part of their business to produce ‘proofs’ of immortality and the existence of God. They have found fault with the proofs of their predecessors — Saint Thomas rejected Saint Anselm's proofs, and Kant rejected Descartes' — but they have supplied new ones of their own. In order to make their proofs seem valid, they have had to falsify logic, to make mathematics mystical, and to pretend that deep seated prejudices were heaven-sent intuitions.

 * Those laws, being forged for universal application, are in perpetual conflict with personal interest, just as personal interest is always in contradiction with the general interest. Good for society, our laws are very bad for the individuals whereof it is composed; for, if they one time protect the individual, they hinder, trouble, fetter him for three quarters of his life.

 * The major religions on the Earth contradict each other left and right. You can't all be correct. And what if all of you are wrong? It's a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I'm not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they're called hypotheses, not inspiration and not revelation.

 * In art, and maybe just in general, the idea is to be able to be really comfortable with contradictory ideas.

 * ... I have something of a guess: Bohr liked paradoxes. I wanted to eliminate contradictions. He liked those contradictions. And — what I said so far is true — but what I am now going to say is probably true. And — Bohr liked contradictions with good reason ... The simple, straightforward way how we see the world ... it is not a wavefunction. It is something that I can describe and understand. If I don't start from such ideas then I can't possibly know what I'm talking about. ... You must start from practical theory with all the contradictions that a detailed observation then leads to. Then as a next step you resolve these contradictions.

 * Philosophy offers the rather cold consolation that perhaps we and our planet do not actually exist; religion presents the contradictory and scarcely more comforting thought that we exist but that we cannot hope to get anywhere until we cease to exist. Alcohol, in attempting to resolve the contradiction, produces vivid patterns of Truth which vanish like snow in the morning sun and cannot be recalled; the revelations of poetry are as wonderful as a comet in the skies, and as mysterious. Love, which was once believed to contain the Answer, we now know to be nothing more than an inherited behavior pattern.

 * The universality or absoluteness of contradiction has a twofold meaning. One is that contradiction exists in the process of development of all things, and the other is that in the process of development of each thing a movement of opposites exists from beginning to end.

 * The sciences are differentiated precisely on the basis of the particular contradictions inherent in their respective objects of study. Thus the contradiction peculiar to a certain field of phenomena constitutes the object of study for a specific branch of science. For example, positive and negative numbers in mathematics; action and reaction in mechanics; positive and negativeelectricity in physics; dissociation and combination in chemistry; forces of production and relations of production, classes and class struggle, in social science; offence and defence in military science; idealism and materialism, the metaphysical outlook and the dialectical outlook, in philosophy; and so on--all these are the objects of study of different branches of science precisely because each branch has its own particular contradiction and particular essence.
