SOCRATES: Then may we assume, Theaetetus, that to-day, and in this casual manner, we have found a truth which in former times many wise men have grown old and have not found?
THEAETETUS: At any rate, Socrates, I am satisfied with the present statement.
SOCRATES: Which is probably correct—for how can there be knowledge apart from definition and true opinion? And yet there is one point in what has been said which does not quite satisfy me.
THEAETETUS: What was it?
SOCRATES: What might seem to be the most ingenious notion of all:—That the elements or letters are unknown, but the combination or syllables known.
THEAETETUS: And was that wrong?
SOCRATES: We shall soon know; for we have as hostages the instances which the author of the argument himself used.
THEAETETUS: What hostages?
SOCRATES: The letters, which are the clements; and the syllables, which are the combinations;—he reasoned, did he not, from the letters of the alphabet?
THEAETETUS: Yes; he did.
