Theaetetus

SOC. He will, I fancy, say all that we have said in his defence and then will close with us, saying contemptuously, Our estimable Socrates here frightened a little boy by asking if it was possible for one and the same person to remember and at the same time not to know one and the same thing, and when the child in his fright said no, because he could not foresee what would result, Socrates made poor me a laughing-stock in his talk. But, you slovenly Socrates, the facts stand thus: when you examine any doctrine of mine by the method of questioning, if the person who is questioned makes such replies as I should make and comes to grief, then I am refuted, but if his replies are quite different, then the person questioned is refuted, not I. Take this example. Do you suppose you could get anybody to admit that the memory a man has of a past feeling he no longer feels is anything like the feeling at the time when he was feeling it? Far from it. Or that he would refuse to admit that it is possible for one and the same person to know and not to know one and the same thing? Or if he were afraid to admit this, would he ever admit that a person who has become unlike is the same as before he became unlike? In fact, if we are to be on our guard against such verbal entanglements, would he admit that a person is one at all, and not many, who become infinite in number, if the process of becoming different continues? But, my dear fellow, he will say, attack my real doctrines in a more generous manner, and prove, if you can, that perceptions, when they come, or become, to each of us, are not individual, or that, if they are individual, what appears to each one would not, for all that, become to that one alone—or, if you prefer to say be, would not be—to whom it appears. But when you talk of pigs and dog-faced baboons, you not only act like a pig yourself, but you persuade your hearers to act so toward my writings, and that is not right. For I maintain that the truth is as I have written; each one of us is the measure of the things that are and those that are not; but each person differs immeasurably from every other in just this, that to one person some things appear and are, and to another person other things. And I do not by any means say that wisdom and the wise man do not exist; on the contrary, I say that if bad things appear and are to any one of us, precisely that man is wise who causes a change and makes good things appear and be to him. And, moreover, do not lay too much stress upon the words of my argument, but get a clearer understanding of my meaning from what I am going to say. Recall to your mind what was said before, that his food appears and is bitter to the sick man, but appears and is the opposite of bitter to the man in health.

SOC.Now neither of these two is to be made wiser than he is—that is not possible— nor should the claim be made that the sick man is ignorant because his opinions are ignorant, or the healthy man wise because his are different; but a change must be made from the one condition to the other, for the other is better. So, too, in education a change has to be made from a worse to a better condition; but the physician causes the change by means of drugs, and the teacher of wisdom by means of words. And yet, in fact, no one ever made anyone think truly who previously thought falsely, since it is impossible to think that which is not or to think any other things than those which one feels; and these are always true. But I believe that a man who, on account of a bad condition of soul, thinks thoughts akin to that condition, is made by a good condition of soul to think correspondingly good thoughts; and some men, through inexperience, call these appearances true, whereas I call them better than the others, but in no wise truer. And the wise, my dear Socrates, I do not by any means call tadpoles when they have to do with the human body, I call them physicians, and when they have to do with plants, husbandmen; for I assert that these latter, when plants are sickly, instil into them good and healthy sensations, and true ones instead of bad sensations, and that the wise and good orators make the good, instead of the evil, seem to be right to their states. For I claim that whatever seems right and honorable to a state is really right and honorable to it, so long as it believes it to be so; but the wise man causes the good, instead of that which is evil to them in each instance, to be and seem right and honorable. And on the same principle the teacher who is able to train his pupils in this manner is not only wise but is also entitled to receive high pay from them when their education is finished. And in this sense it is true that some men are wiser than others, and that no one thinks falsely, and that you, whether you will or no, must endure to be a measure. Upon these positions my doctrine stands firm; and if you can dispute it in principle, dispute it by bringing an opposing doctrine against it; or if you prefer the method of questions, ask questions; for an intelligent person ought not to reject this method, on the contrary, he should choose it before all others. However, let me make a suggestion: do not be unfair in your questioning; it is very inconsistent for a man who asserts that he cares for virtue to be constantly unfair in discussion; and it is unfair in discussion when a man makes no distinction between merely trying to make points and carrying on a real argument.

SOC.In the former he may jest and try to trip up his opponent as much as he can, but in real argument he must be in earnest and must set his interlocutor on his feet, pointing out to him those slips only which are due to himself and his previous associations. For if you act in this way, those who debate with you will cast the blame for their confusion and perplexity upon themselves, not upon you; they will run after you and love you, and they will hate themselves and run away from themselves, taking refuge in philosophy, that they may escape from their former selves by becoming different. But if you act in the opposite way, as most teachers do, you will produce the opposite result, and instead of making your young associates philosophers, you will make them hate philosophy when they grow older. If therefore, you will accept the suggestion which I made before, you will avoid a hostile and combative attitude and in a gracious spirit will enter the lists with me and inquire what we really mean when we declare that all things are in motion and that whatever seems is to each individual, whether man or state. And on the basis of that you will consider the question whether knowledge and perception are the same or different, instead of doing as you did a while ago, using as your basis the ordinary meaning of names and words, which most people pervert in haphazard ways and thereby cause all sorts of perplexity in one another. Such, Theodorus, is the help I have furnished your friend to the best of my ability—not much, for my resources are small; but if he were living himself he would have helped his offspring in a fashion more magnificent.

THEO. You are joking, Socrates, for you have come to the man’s assistance with all the valor of youth.

SOC. Thank you, my friend. Tell me, did you observe just now that Protagoras reproached us for addressing our words to a boy, and said that we made the boy’s timidity aid us in our argument against his doctrine, and that he called our procedure a mere display of wit, solemnly insisting upon the importance of the measure of all things, and urging us to treat his doctrine seriously?

THEO. Of course I observed it, Socrates.

SOC. Well then, shall we do as he says?

THEO. By all means.

SOC. Now you see that all those present, except you and myself are boys. So if we are to do as the man asks, you and I must question each other and make reply in order to show our serious attitude towards his doctrine; then he cannot, at any rate, find fault with us on the ground that we examined his doctrine in a spirit of levity with mere boys.

THEO. Why is this? Would not Theaetetus follow an investigation better than many a man with a long beard?
