You can prove anything you want by coldly logical reason---if you pick the proper postulates.
Finally there are simple ideas of which no definition can be given; there are also axioms or postulates, or in a word primary principles, which cannot be proved and have no need of proof.
The prophet who fails to present a bearable alternative and yet preaches doom is part of the trap that he postulates. Not only does he picture us caught in a tremendous man-made or God-made trap from which there is no escape, but we must also listen to him day in, day out, describe how the trap is inexorably closing. To such prophecies the human race, as presently bred and educated and situated, is incapable of listening. So some dance and some immolate themselves as human torches some take drugs and some artists spill their creativity in sets of randomly placed dots on a white ground.
It is this way that in mathematics speculative theorems and practical canons are reduced by analysis to definitions, axioms and postulates.
... There can be no doubt about faith and not reason being the ultima ratio. Even Euclid, who has laid himself as little open to the charge of credulity as any writer who ever lived, cannot get beyond this. He has no demonstrable first premise. He requires postulates and axioms which transcend demonstration, and without which he can do nothing. His superstructure indeed is demonstration, but his ground his faith. Nor again can he get further than telling a man he is a fool if he persists in differing from him. He says 'which is absurd,' and declines to discuss the matter further. Faith and authority, therefore, prove to be as necessary for him as for anyone else.
A reader who quarrels with postulates, who dislikes Hamlet because he does not believe that there are ghosts or that people speak in pentameters, clearly has no business in literature.
I should make a distinction between two kinds of readjustment in the case of a conflict with experience, namely, between a change in the language, and a mere change in or addition of, a truth-value ascribed to an indeterminate statement (i.e. a statement whose truth value is not fixed by the rules of language, say by the postulates of logic, mathematics and physics). A change of the first kind constitutes a radical alteration, sometimes a revolution, and it occurs only at certain historically decisive points in the development of science. On the other hand, changes of the second kind occur every minute. A change of the first kind constitutes, strictly speaking, a transition from a language Ln into a new language Ln1.
Beginning from a few intuitive postulates, far reaching consequences could be derived, and I took immediately to the sport of proving theorems.
I don't believe in the dogmatic postulates of Marxist revolution. I don't accept that we are living in a period of proletarian revolutions... Are we aiming in Venezuela today for the abolition of private property or a classless society I don't think so.
Simulated disorder postulates perfect discipline; simulated fear postulates courage; simulated weakness postulates strength.
I do not believe in the divinity of Christ, and there are many other of the postulates of the orthodox creed to which I cannot subscribe.
We hear much nowadays as to the speculative ideas of men concerning the condition beyond the grave but the admission that there is an individual existence beyond the grave, is a declaration that there must have been an individual, intelligent creation before we came here in the flesh. Life beyond the grave postulates a pre-existent state.
