“It is necessary.”

“What, then?  Are we affected in some such way, or not, with respect to things equal and abstract equality itself?”

“Assuredly.”

“It is necessary, therefore, that we must have known abstract equality before the time when, on first seeing equal things, we perceived that they all aimed at resembling equality, but failed in doing so.”

“Such is the case.”

53.  “Moreover, we admit this too, that we perceived this, and could not possibly perceive it by any other means than the sight, or touch, or some other of the senses, for I say the same of them all.”

“For they are the same, Socrates, so far as, our argument is concerned.”

“However, we must perceive, by means of the senses, that all things which come under the senses aim at that abstract equality, and yet fall short of it; or how shall we say it is?”

“Even so.”

“Before, then, we began to see, and hear, and use our other senses, we must have had a knowledge of equality itself—­what it is, if we were to refer to it those equal things that come under the senses, and observe that all such things aim at resembling that, but fall far short of it.”

“This necessarily follows, Socrates, from what has been already said.”

“But did we not, as soon as we were born, see and hear, and possess our other senses?”

“Certainly.”

“But, we have said, before we possessed these, we must have had a knowledge of abstract equality?”

“Yes.”

“We must have had it, then, as it seems, before we were born.”

“It seems so.”

54.  “If, therefore, having this before we were born, we were born possessing it, we knew, both before we were born and as soon as we were born, not only the equal and the greater and smaller, but all things of the kind; for our present discussion is not more respecting equality than the beautiful itself, the good, the just, and the holy, and, in one word, respecting every thing which we mark with the seal of existence, both in the questions we ask and the answers we give.  So that we must necessarily have had a knowledge of all these before we were born.”

“Such is the case.”

“And if, having once had it, we did not constantly forget it, we should always be born with this knowledge, and should always retain it through life.  For to know is this, when one has got a knowledge of any thing, to retain and not lose it; for do we not call this oblivion, Simmias, the loss of knowledge?”

“Assuredly, Socrates,” he replied.

55.  “But if, having had it before we were born, we lose it at our birth, and afterward, through exercising the senses about these things, we recover the knowledge which we once before possessed, would not that which we call learning be a recovery of our own knowledge?  And in saying that this is to remember, should we not say rightly?”
