“A person who thinks by images becomes less and less capable of thinking by reasoning, and vice versa. The intellectual process based on images is contradictory to the intellectual process of reasoning that is related to the word. There are two different ways of dealing with an object. They involve not only different approaches, but even more important, opposing mental attitudes. This is not a matter of complementary processes, such as analysis and synthesis or logic and dialectic. These processes lack any qualitative common denominator.”

“Images produce an intellectual process different from the ancient one or the one developed by classical education. It goes without saying that this process is not completely new; of course, since sight existed, and since people themselves chose their images, they also thought by means of images and entered into this kind of thinking. But this was limited and not frequent, because images were not dominant. The new factor in our day comes from the effect of visual reproduction’s triumph over all else, which involves us in the domination of one form of thought. This supremacy is new, even though we are not dealing with a completely new form of thought.”

Jacques Ellul (1912–1994) French sociologist, technology critic, and Christian anarchist

“The image that creates this thinking gives rise to a feeling of evidence and a conviction that it is not based on reason. This kind of thinking explains the reaction we so often note among our contemporaries: when someone asks them to give the reason for their opinions, they answer: "It’s evident." This thinking, which creates prejudices and stereotypes, is the domain of the unquestionable. Obviously you cannot dispute with an image, and you cannot challenge the hero of a film. But this extends to the mental images produced by the film: there is no criticism or debate possible, because these involve differing methods of thought. What produces immediate assent cannot bear the discussion process. The conviction acquired in this way can only be attacked on its own ground: by other images.”

Jacques Ellul (1912–1994) French sociologist, technology critic, and Christian anarchist

“Determinism, in the strict sense, is self-contradictory. For if man’s mental processes—specifically, his attempts at reasoning—are not free, if they are determined by environment and heredity, then there is no means of claiming that theory x is true and y is false—since man can have no way of knowing that his mental processes might not be conditioned to force him to believe that x is logical, when in fact it is not.”

Roy A. Childs, Jr. (1949–1992) American libertarian essayist and critic

“Nothing is more perplexing to a man than the mental process of a woman who reasons her emotions.”

Edith Wharton (1862–1937) American novelist, short story writer, designer

“Technology discloses the active relation of man towards nature, as well as the direct process of production of his very life, and thereby the process of production of his basic societal relations, of his own mentality, and his images of society, too.”

Karl Marx (1818–1883) German philosopher, economist, sociologist, journalist and revolutionary socialist

“Every difference in men's concepts should be regarded as reflecting an objective contradiction. Objective contradictions are reflected in subjective thinking, and this process constitutes the contradictory movement of concepts, pushes forward the development of thought, and ceaselessly solves problems in man's thinking.”

Mao Zedong book On Contradiction

“While mere process of thinking is the process of habits, ideals, definitions, investigations, classifications, valuations and behavior, due process of thinking, which is due process of law, is the process of correct habits, right ideals, true definitions, sincere investigation, reasonable classification, reasonable value, and justice; whereas its opposite, undue process, is perverse habit, wrong ideals, double meanings, partial investigation, class legislation, confiscation and injustice.”

John R. Commons (1862–1945) United States institutional economist and labor historian

“Creative insight is not the final link in a chain of reasoning. If it were that, it would not strike us as inspired in its origin. Intuition is not the end, but part of an ever-developing and ever-dynamic process of realization. There is continual system of “checks and balances” between intuition and the logical method of discursive reasoning. Cognitive intuitions are not substitutes for thought, they are challenges to intelligence. Mere intuitions are blind while intellectual work is empty. All processes are partly intuitive and partly intellectual. There is no gulf between the two.”

Sarvepalli Radhakrishnan (1888–1975) Indian philosopher and statesman who was the first Vice President and the second President of India

“But after a while, some higher brain-center cut in, and I began being mentally able to fit the wildly changing scenery into a coherent four-dimensional whole. The process was really no more devious than the process by which one integrates the two hundred lines of a TV screen into a single two-dimensional image... which in turn is interpreted as a three-dimensional scene. It's just a matter of processing information. Impossible? I saw.”

Rudy Rucker (1946) American mathematician, computer scientist, science fiction author and philosopher
