11
Have you anything to show us, then, for this application, beyond the fact of its seeming so to you? And does a madman act any otherwise than seems to him right? Is this, then, a sufficient criterion for him too?
11
It is not.
11
Come, therefore, to some stronger ground than seeming.
11
What is that?
11
The beginning of philosophy is this: the being sensible of the disagreement of men with each other; an inquiry into the cause of this disagreement; and a disapprobation and distrust of what merely seems; a careful examination into what seems, whether it seem rightly; and the discovery of some rule which shall serve like a balance, for the determination of weights; like a square, for distinguishing straight and crooked. This is the beginning of philosophy.
11
Is it possible that all things which seem right to all persons are so? Can things contradictory be right? We say not all things; but all that seem so to us. And why more to you than to the Syrians or Egyptians; than to me, or to any other man? Not at all more.
11
Therefore, what seems to each man is not sufficient to determine the reality of a thing; for even in weights and measures we are not satisfied with the bare appearance, but for everything we find some rule. And is there, then, in the present case no rule preferable to what seems? Is it possible that what is of the greatest necessity in human life should be left incapable of determination and discovery?
11
There must be some rule. And why do we not seek and discover it, and, when we have discovered, ever after make use of it, without fail, so as not even to move a finger without it? For this, I conceive, is what, when found, will cure those of their madness who make use of no other measure but their own perverted way of thinking. Afterwards, beginning from certain known and determinate points, we may make use of general principles, properly applied to particulars.
