Reductio Ad Absurdum Quotes & Sayings

The reductio ad absurdum is God's favorite argument. — George Tyrrell

It rests on the attempt since the 1970s to translate a pathological degeneration of the principle of laissez-faire into economic reality by the systematic retreat of states from any regulation or control of the activities of profit-making enterprise. This attempt to hand over human society to the (allegedly) self-controlling and wealth- or even welfare-maximising market, populated (allegedly) by actors in rational pursuit of their interests, had no precedent in any earlier phase of capitalist development in any developed economy, not even the USA. It was a reductio ad absurdum of what its ideologists read into Adam Smith, as the correspondingly extremist 100% state-planned command economy of the USSR was of what the Bolsheviks read into Marx. — Eric Hobsbawm

If God existed (a question concerning which Jubal maintained a meticulous intellectual neutrality) and if He desired to be worshiped (a proposition which Jubal found inherently improbable but conceivably possible in the dim light of his own ignorance), then (stipulating affirmatively both the above) it nevertheless seemed wildly unlikely to Jubal to the point of reductio ad absurdum that a God potent to shape galaxies would be titillated and swayed by the whoop-te-do nonsense the Fosterites offered Him as worship. — Robert A. Heinlein

The housewife is an unpaid worker in her husband's house in return for the security of being a permanent employee: hers is the reductio ad absurdum of the employee who accepts a lower wage in return for permanence of his employment. But the lowest paid employees can be and are laid off, and so are wives. They have no savings, no skills which they can bargain with elsewhere, and they must bear the stigma of having been sacked. — Germaine Greer

It seemed a ruse that fear of death should be the sole motivation for living and, yet, to quell this fear made the prospect of living itself seem all the more absurd; to extend this further, the notion of living one's life for the purposes of pondering the absurdity of living was an even greater absurdity in and of itself, which thus, by reductio ad absurdum, rendered the fear of death a necessary function of life and any lack thereof, a trifling matter rooted in self-inflicted incoherence. — Ashim Shanker

Reductio ad absurdum, which Euclid loved so much, is one of a mathematician's finest weapons. It is a far finer gambit than any chess play: a chess player may offer the sacrifice of a pawn or even a piece, but a mathematician offers the game. — G.H. Hardy

The obvious reductio ad absurdum is Holocaust deniers: Should their perspective be provided, for "balance," any time someone writes about the Holocaust? — Chris Mooney

Some have said that the thesis [of indeterminacy] is a consequence of my behaviorism. Some have said that it is a reductio ad absurdum of my behaviorism. I disagree with this second point, but I agree with the first. I hold further that the behaviorism approach is mandatory. In psychology one may or may not be a behaviorist, but in linguistics one has no choice. — Willard Van Orman Quine

The second [argument about motion] is the so-called Achilles, and it amounts to this, that in a race the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.
Statement of the Achilles and the Tortoise paradox in the relation of the discrete to the continuous.; perhaps the earliest example of the reductio ad absurdum method of proof. — Zeno Of Elea

A good sense of humour is the sign of a healthy perspective, which is why people who are uncomfortable around humour are either pompous (inflated) or neurotic (oversensitive). Pompous people mistrust humour because at some level they know their self-importance cannot survive very long in such an atmosphere, so they criticise it as "negative" or "subversive." Neurotics, sensing that humour is always ultimately critical, view it as therefore unkind and destructive, a reductio ad absurdum which leads to political correctness. Not that laughter can't be unkind and destructive. Like most manifestations of human behaviour it ranges from the loving to the hateful. The latter produces nasty racial jokes and savage teasing; the former, warm and affectionate banter, and the kind of inclusive humour that says, "Isn't the human condition absurd, but we're all in the same boat. — John Cleese

Imagism was a reductio ad absurdum of one or two tendencies of romanticism, such a beautifully and finally absurd one that it is hard to believe it existed as anything but a logical construction; and what imagist found it possible to go on writing imagist poetry? A number of poets have stopped writing entirely; others, like recurring decimals, repeat the novelties they commeced with, each time less valuably than before. And there are surrealist poetry, and political poetry, and all the othe refuges of the indigent. — Randall Jarrell

The great German idealists from Kant to Hegel saw this idealism or nihilism as a reductio ad absurdum of any philosophy, and so they struggled by all conceptual means to avoid it. — Frederick C. Beiser

The reductio ad absurdum of M.D.'s view, I argued, was that science devises ever bloodier means of war until humanity's powers of destruction overcome our powers of creation and our civilization drives itself to extinction. M.D. embraced my objection with mordant glee. 'Precisely. Our will to power, our science, and those v. faculties that elevated us from apes, to saves, to modern man, are the same faculties that'll snuff out Homo Sapiens before this century is out! You'll probably live to see it happen, you fortunate son. What a symphonic crescendo that'll be, eh? — David Mitchell
