“The subversive character of truth inflicts upon thought an imperative quality. Logic centers on judgments which are, as demonstrative propositions, imperatives, — the predicative “is” implies an “ought.” … Verification of the proposition involves a process in fact as well as in thought: (S) must become that which it is. The categorical statement thus turns into a categorical imperative; it does not state a fact but the necessity to bring about a fact. For example, it could be read as follows: man is not (in fact) free, endowed with inalienable rights, etc., but he ought to be.”

“Poetry is an ethic. By ethic I mean a secret code of behavior, a discipline constructed and conducted according to the capabilities of a man who rejects the falsifications of the categorical imperative.”

Jean Cocteau (1889–1963) French poet, novelist, dramatist, designer, boxing manager and filmmaker

Diary of an Unknown (1988), On Invisibility
Context: Poetry is an ethic. By ethic I mean a secret code of behavior, a discipline constructed and conducted according to the capabilities of a man who rejects the falsifications of the categorical imperative.
This personal morality may appear to be immorality itself in the eyes of those who lie to themselves, or who live a life of confusion, in such a manner that, for them, a lie becomes the truth, and our truth becomes a lie...

“No combination of circumstances ever cancels this obligation. If there are circumstances which seem to cancel it as regards a certain man or category of men, they impose it in fact all the more imperatively.”

Simone Weil (1909–1943) French philosopher, Christian mystic, and social activist

Draft for a Statement of Human Obligation (1943)
Context: Anyone whose attention and love are really directed towards the reality outside the world recognizes at the same time that he is bound, both in public and private life, by the single and permanent obligation to remedy, according to his responsibilities and to the extent of his power, all the privations of soul and body which are liable to destroy or damage the earthly life of any human being whatsoever.
This obligation cannot legitimately be held to be limited by the insufficiency of power or the nature of the responsibilities until everything possible has been done to explain the necessity of the limitation to those who will suffer by it; the explanation must be completely truthful and must be such as to make it possible for them to acknowledge the necessity.
No combination of circumstances ever cancels this obligation. If there are circumstances which seem to cancel it as regards a certain man or category of men, they impose it in fact all the more imperatively.
The thought of this obligation is present to all men, but in very different forms and in very varying degrees of clarity. Some men are more and some are less inclined to accept — or to refuse — it as their rule of conduct.

“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”

“Pure Mathematics is the class of all propositions of the form “p implies q,” where p and q are propositions containing one or more variables, the same in the two propositions, and neither p nor q contains any constants except logical constants. And logical constants are all notions definable in terms of the following: Implication, the relation of a term to a class of which it is a member, the notion of such that, the notion of relation, and such further notions as may be involved in the general notion of propositions of the above form. In addition to these, mathematics uses a notion which is not a constituent of the propositions which it considers, namely the notion of truth.”

Bertrand Russell (1872–1970) logician, one of the first analytic philosophers and political activist

“There are periods in the life of human society when revolution becomes an imperative necessity, when it proclaims itself as inevitable.”

The Spirit of Revolt (1880)
Context: There are periods in the life of human society when revolution becomes an imperative necessity, when it proclaims itself as inevitable. New ideas germinate everywhere, seeking to force their way into the light, to find an application in life; everywhere they are opposed by the inertia of those whose interest it is to maintain the old order; they suffocate in the stifling atmosphere of prejudice and traditions.
