“Censorship ends in logical completeness when nobody is allowed to read any books except the books that nobody can read.”

George Bernard Shaw (1856–1950) Irish playwright

As quoted in "Literary Censorship in England" in Current Opinion, Vol. 55, No. 5 (November 1913), p. 378; this has sometimes appeared on the internet in paraphrased form as "Censorship ends in logical completeness when nobody is allowed to read any books except the books that nobody reads"
1910s
Context: Any public committee man who tries to pack the moral cards in the interest of his own notions is guilty of corruption and impertinence. The business of a public library is not to supply the public with the books the committee thinks good for the public, but to supply the public with the books the public wants. … Censorship ends in logical completeness when nobody is allowed to read any books except the books that nobody can read. But as the ratepayer is mostly a coward and a fool in these difficult matters, and the committee is quite sure that it can succeed where the Roman Catholic Church has made its index expurgatorius the laughing-stock of the world, censorship will rage until it reduces itself to absurdity; and even then the best books will be in danger still.

“A year here and he still dreamed of cyberspace, hope fading nightly. All the speed he took, all the turns he'd taken and the corners he'd cut in Night City, and he'd still see the matrix in his sleep, bright lattices of logic unfolding across that colorless void…”

Context: A year here and he still dreamed of cyberspace, hope fading nightly. All the speed he took, all the turns he'd taken and the corners he'd cut in Night City, and he'd still see the matrix in his sleep, bright lattices of logic unfolding across that colorless void… The Sprawl was a long strange way home over the Pacific now, and he was no console man, no cyberspace cowboy. Just another hustler, trying to make it through. But the dreams came on in the Japanese night like livewire voodoo, and he'd cry for it, cry in his sleep, and wake alone in the dark, curled in his capsule in some coffin hotel, his hands clawed into the bedslab, temperfoam bunched between his fingers, trying to reach the console that wasn't there.

“In life two negatives don't make a positive. Double negatives turn positive only in math and formal logic. In life things just get worse and worse and worse.”

“Logic is a way of saying that anything which didn't happen yesterday won't happen tomorrow.”

Glory Road (1963)
Context: Logic is a feeble reed, friend. "Logic" proved that airplanes can't fly and that H-bombs won't work and that stones don't fall out of the sky. Logic is a way of saying that anything which didn't happen yesterday won't happen tomorrow.

Context: “Do you seriously expect to start a rebellion with picayune stuff like that?”
“It’s not picayune stuff, because it acts directly on their emotions, below the logical level. You can sway a thousand men by appealing to their prejudices quicker than you can convince one man by logic. It doesn’t have to be a prejudice about an important matter either.

“Logic may indeed be unshakeable, but it cannot withstand a man who is determined to live.”

Source: The Trial (1920), Ch. 10
Context: Logic may indeed be unshakeable, but it cannot withstand a man who is determined to live. Where was the judge he had never seen? Where was the High Court he had never reached? He raised his hands and spread out all his fingers. But the hands of one of the men closed round his throat, just as the other drove the knife deep into his heart and turned it twice.

“The first question we should face is: What is the aim of a physical theory? To this question diverse answers have been made, but all of them may be reduced to two main principles:
"A physical theory," certain logicians have replied, "has for its object the explanation of a group of laws experimentally established."
"A physical theory," other thinkers have said, "is an abstract system whose aim is to summarize and classify logically a group of experimental laws without claiming to explain these laws…
Now these two questions — Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? — do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics.
Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics…
Now, to make physical theories depend on metaphysics is surely not the way to let them enjoy the privilege of universal consent.”

“Consider some of the qualities of typical modernistic poetry: very interesting language, a great emphasis on connotation, "texture"; extreme intensity, forced emotion — violence; a good deal of obscurity; emphasis on sensation, perceptual nuances; emphasis on details, on the part rather than on the whole; experimental or novel qualities of some sort; a tendency toward external formlessness and internal disorganization — these are justified, generally, as the disorganization required to express a disorganized age, or, alternatively, as newly discovered and more complex types of organization; an extremely personal style — refine your singularities; lack of restraint — all tendencies are forced to their limits; there is a good deal of emphasis on the unconscious, dream structure, the thoroughly subjective; the poet's attitudes are usually anti-scientific, anti-common-sense, anti-public — he is, essentially, removed; poetry is primarily lyric, intensive — the few long poems are aggregations of lyric details; poems usually have, not a logical, but the more or less associational style of dramatic monologue; and so on and so on. This complex of qualities is essentially romantic; and the poetry that exhibits it represents the culminating point of romanticism.”
