THEAETETUS: Yes, he says so.
SOCRATES: A wise man is not likely to talk nonsense. Let us try to understand him: the same wind is blowing, and yet one of us may be cold and the other not, or one may be slightly and the other very cold?
THEAETETUS: Quite true.
SOCRATES: Now is the wind, regarded not in relation to us but absolutely, cold or not; or are we to say, with Protagoras, that the wind is cold to him who is cold, and not to him who is not?
THEAETETUS: I suppose the last.
SOCRATES: Then it must appear so to each of them?
THEAETETUS: Yes.
SOCRATES: And 'appears to him' means the same as 'he perceives.'
THEAETETUS: True.
SOCRATES: Then appearing and perceiving coincide in the case of hot and cold, and in similar instances; for things appear, or may be supposed to be, to each one such as he perceives them?
