“
[89d] “The danger of becoming misologists or haters of argument,” said he, “as people become misanthropists or haters of man; for no worse evil can happen to a man than to hate argument. Misology and misanthropy arise from similar causes. For misanthropy arises from trusting someone implicitly without sufficient knowledge. You think the man is perfectly true and sound and trustworthy, and afterwards you find him base and false. Then you have the same experience with another person. By the time this has happened to a man a good many times, especially if it happens among those whom he might regard as his nearest [89e] and dearest friends, he ends by being in continual quarrels and by hating everybody and thinking there is nothing sound in anyone at all. Have you not noticed this?”
“Certainly,” said I.
“Well,” he went on, “is it not disgraceful, and is it not plain that such a man undertakes to consort with men when he has no knowledge of human nature? For if he had knowledge when he dealt with them, he would think that the good [90a] and the bad are both very few and those between the two are very many, for that is the case.”
“What do you mean?”
“I mean just what I might say about the large and small. Do you think there is anything more unusual than to find a very large or a very small man, or dog, or other creature, or again, one that is very quick or slow, very ugly or beautiful, very black or white? Have you not noticed that the extremes in all these instances are rare and few, and the examples between the extremes are very many?”
“To be sure,” said I.
“And don't you think,” [90b] said he, “that if there were to be a competition in rascality, those who excelled would be very few in that also?”
“Very likely,” I replied.
“Yes, very likely,” he said, “But it is not in that respect that arguments are like men; I was merely following your lead in discussing that. The similarity lies in this: when a man without proper knowledge concerning arguments has confidence in the truth of an argument and afterwards thinks that it is false, whether it really is so or not, and this happens again and again; then you know, those men especially who [90c] have spent their time in disputation come to believe that they are the wisest of men and that they alone have discovered that there is nothing sound or sure in anything, whether argument or anything else, but all things go up and down, like the tide in the Euripus, and nothing is stable for any length of time.”
“Certainly,” I said, “that is very true.”
“Then, Phaedo,” he said, “if there is any system of argument which is true and sure and can be learned, it would be a sad thing if a man, [90d] because he has met with some of those arguments which seem to be sometimes true and sometimes false, should then not blame himself or his own lack of skill, but should end, in his vexation, by throwing the blame gladly upon the arguments and should hate and revile them all the rest of his life, and be deprived of the truth and knowledge of reality”.
