Jowett: Truth

Her. But how inconsistent should I be, if, whilst repudiating Protagoras and his Truth, I were to attach any value to what he and his book affirm ! CRATYLUS  

Soc. In the name of the Graces, what an almighty wise man Protagoras must have been ! He spoke these things in a parable to the common herd, like you and me, but told the truth, his Truth, in secret to his own disciples. THEAETETUS  

Soc. I am charmed with his doctrine, that what appears is to each one, but I wonder that he did not begin his book on Truth with a declaration that a pig or a dog-faced baboon, or some other yet stranger monster which has sensation, is the measure of all things ; then he might have shown a magnificent contempt for our opinion of him by informing us at the outset that while we were reverencing him like a God for his wisdom he was no better than a tadpole, not to speak of his fellow-men — would not this have produced an over-powering effect ? For if truth is only sensation, and no man can discern another’s feelings better than he, or has any superior right to determine whether his opinion is true or false, but each, as we have several times repeated, is to himself the sole judge, and everything that he judges is true and right, why, my friend, should Protagoras be preferred to the place of wisdom and instruction, and deserve to be well paid, and we poor ignoramuses have to go to him, if each one is the measure of his own wisdom ? Must he not be talking ad captandum in all this ? I say nothing of the ridiculous predicament in which my own midwifery and the whole art of dialectic is placed ; for the attempt to supervise or refute the notions or opinions of others would be a tedious and enormous piece of folly, if to each man his own are right ; and this must be the case if Protagoras Truth is the real truth, and the philosopher is not merely amusing himself by giving oracles out of the shrine of his book. THEAETETUS

Soc. Then, if we are not able to hunt the good with one idea only, with three we may catch our prey ; Beauty, Symmetry, Truth are the three, and these taken together we may regard as the single cause of the mixture, and the mixture as being good by reason of the infusion of them. PHILEBUS  

Cle. Truth, Stranger, is a noble thing and a lasting, but a thing of which men are hard to be persuaded. LAWS BOOK II

Truth is the beginning of every good thing, both to Gods and men ; and he who would be blessed and happy, should be from the first a partaker of the truth, that he may live a true man as long as possible, for then he can be trusted ; but he is not to be trusted who loves voluntary falsehood, and he who loves involuntary falsehood is a fool. Neither condition is enviable, for the untrustworthy and ignorant has no friend, and as time advances he becomes known, and lays up in store for himself isolation in crabbed age when life is on the wane : so that, whether his children or friends are alive or not, he is equally solitary. — Worthy of honour is he who does no injustice, and of more than twofold honour, if he not only does no injustice himself, but hinders others from doing any ; the first may count as one man, the second is worth many men, because he informs the rulers of the injustice of others. And yet more highly to be esteemed is he who co-operates with the rulers in correcting the citizens as far as he can — he shall be proclaimed the great and perfect citizen, and bear away the palm of virtue. The same praise may be given about temperance and wisdom, and all other goods which may be imparted to others, as well as acquired by a man for himself ; he who imparts them shall be honoured as the man of men, and he who is willing, yet is not able, may be allowed the second place ; but he who is jealous and will not, if he can help, allow others to partake in a friendly way of any good, is deserving of blame : the good, however, which he has, is not to be undervalued by us because it is possessed by him, but must be acquired by us also to the utmost of our power. Let every man, then, freely strive for the prize of virtue, and let there be no envy. For the unenvious nature increases the greatness of states — he himself contends in the race, blasting the fair fame of no man ; but the envious, who thinks that he ought to get the better by defaming others, is less energetic himself in the pursuit of true virtue, and reduces his rivals to despair by his unjust slanders of them. And so he makes the whole city to enter the arena untrained in the practice of virtue, and diminishes her glory as far as in him lies. Now every man should be valiant, but he should also be gentle. From the cruel, or hardly curable, or altogether incurable acts of injustice done to him by others, a man can only escape by fighting and defending himself and conquering, and by never ceasing to punish them ; and no man who is not of a noble spirit is able to accomplish this. As to the actions of those who do evil, but whose evil is curable, in the first place, let us remember that the unjust man is not unjust of his own free will. For no man of his own free will would choose to possess the greatest of evils, and least of all in the most honourable part of himself. And the soul, as we said, is of a truth deemed by all men the most honourable. In the soul, then, which is the most honourable part of him, no one, if he could help, would admit, or allow to continue the greatest of evils. The unrighteous and vicious are always to be pitied in any case ; and one can afford to forgive as well as pity him who is curable, and refrain and calm one’s anger, not getting into a passion, like a woman, and nursing ill-feeling. But upon him who is incapable of reformation and wholly evil, the vials of our wrath should be poured out ; wherefore I say that good men ought, when occasion demands, to be both gentle and passionate. LAWS BOOK V

And let us ask and answer in turn, first going back to the description of the gentle and noble nature. Truth, as you will remember, was his leader, whom he followed always and in all things ; failing in this, he was an impostor, and had no part or lot in true philosophy. THE REPUBLIC   BOOK VI
