Θεαίτητος

Θεαίτητος Plato
189 THEAET. After what manner?
189 SOC. We say that false opinion is a kind of interchanged opinion, when a person makes an exchange in his mind and says that one thing which exists is another thing which exists. For in this way he always holds an opinion of what exists, but of one thing instead of another; so he misses the object he was aiming at in his thought and might fairly be said to hold a false opinion.
189 THEAET. Now you seem to me to have said what is perfectly right. For when a man, in forming an opinion, puts ugly instead of beautiful, or beautiful instead of ugly, he does truly hold a false opinion.
189 SOC. Evidently, Theaetetus, you feel contempt of me, and not fear.
189 THEAET. Why in the world do you say that?
189 SOC. You think, I fancy, that I would not attack your truly false by asking whether it is possible for a thing to become slowly quick or heavily light, or any other opposite, by a process opposite to itself, in accordance, not with its own nature, but with that of its opposite. But I let this pass, that your courage may not fail. You are satisfied, you say, that false opinion is interchanged opinion?
189 THEAET. I am.
189 SOC. It is, then, in your opinion, possible for the mind to regard one thing as another and not as what it is.
189 THEAET. Yes, it is.
189 SOC. Now when one’s mind does this, does it not necessarily have a thought either of both things together or of one or the other of them?
189 THEAET. Yes, it must; either of both at the same time or in succession.
189 SOC. Excellent. And do you define thought as I do?
189 THEAET. How do you define it?
