Soc. They spoke of a glorious truth, as I
conceive.
Men. What was it? and who were they?
Soc. Some of them were priests and priestesses, who had
studied how they might be able to give a reason of their profession: there,
have been poets also, who spoke of these things by inspiration, like Pindar,
and many others who were inspired. And they say-mark, now, and see whether
their words are true-they say that the soul of man is immortal, and at
one time has an end, which is termed dying, and at another time is born
again, but is never destroyed. And the moral is, that a man ought to live
always in perfect holiness. "For in the ninth year Persephone sends the
souls of those from whom she has received the penalty of ancient crime
back again from beneath into the light of the sun above, and these are
they who become noble kings and mighty men and great in wisdom and are
called saintly heroes in after ages." The soul, then, as being immortal,
and having been born again many times, rand having seen all things that
exist, whether in this world or in the world below, has knowledge of them
all; and it is no wonder that she should be able to call to remembrance
all that she ever knew about virtue, and about everything; for as all nature
is akin, and the soul has learned all things; there is no difficulty in
her eliciting or as men say learning, out of a single recollection -all
the rest, if a man is strenuous and does not faint; for all enquiry and
all learning is but recollection. And therefore we ought not to listen
to this sophistical argument about the impossibility of enquiry: for it
will make us idle; and is sweet only to the sluggard; but the other saying
will make us active and inquisitive. In that confiding, I will gladly enquire
with you into the nature of virtue.
Men. Yes, Socrates; but what do you mean by saying that
we do not learn, and that what we call learning is only a process of recollection?
Can you teach me how this is?
Soc. I told you, Meno, just now that you were a rogue, and
now you ask whether I can teach you, when I am saying that there is no
teaching, but only recollection; and thus you imagine that you will involve
me in a contradiction.
Men. Indeed, Socrates, I protest that I had no such intention.
I only asked the question from habit; but if you can prove to me that what
you say is true, I wish that you would.
Soc. It will be no easy matter, but I will try to please
you to the utmost of my power. Suppose that you call one of your numerous
attendants, that I may demonstrate on him.
Men. Certainly. Come hither, boy.
Soc. He is Greek, and speaks Greek, does he
not?
Men. Yes, indeed; he was born in the
house.
Soc. Attend now to the questions which I ask him, and observe
whether he learns of me or only remembers.
Men. I will.
Soc. Tell me, boy, do you know that a figure like this is
a square?
Boy. I do.
Soc. And you know that a square figure has these four lines
equal?
Boy. Certainly.
Soc. And these lines which I have drawn through the middle
of the square are also equal?
Boy. Yes.
Soc. A square may be of any size?
Boy. Certainly.
Soc. And if one side of the figure be of two feet, and the
other side be of two feet, how much will the whole be? Let me explain:
if in one direction the space was of two feet, and in other direction of
one foot, the whole would be of two feet taken once?
Boy. Yes.
Soc. But since this side is also of two feet, there are
twice two feet?
Boy. There are.
Soc. Then the square is of twice two
feet?
Boy. Yes.
Soc. And how many are twice two feet? count and tell
me.
Boy. Four, Socrates.
Soc. And might there not be another square twice as large
as this, and having like this the lines equal?
Boy. Yes.
Soc. And of how many feet will that be?
Boy. Of eight feet.
Soc. And now try and tell me the length of the line which
forms the side of that double square: this is two feet-what will that
be?
Boy. Clearly, Socrates, it will be double.
Soc. Do you observe, Meno, that I am not teaching the boy
anything, but only asking him questions; and now he fancies that he knows
how long a line is necessary in order to produce a figure of eight square
feet; does he not?
Men. Yes.
Soc. And does he really know?
Men. Certainly not.
Soc. He only guesses that because the square is double,
the line is double.
Men. True.
Soc. Observe him while he recalls the steps in regular order.
(To the Boy.) Tell me, boy, do you assert that a double space comes from
a double line? Remember that I am not speaking of an oblong, but of a figure
equal every way, and twice the size of this-that is to say of eight feet;
and I want to know whether you still say that a double square comes from
double line?
Boy. Yes.
Soc. But does not this line become doubled if we add another
such line here?
Boy. Certainly.
Soc. And four such lines will make a space containing eight
feet?
Boy. Yes.
Soc. Let us describe such a figure: Would you not say that
this is the figure of eight feet?
Boy. Yes.
Soc. And are there not these four divisions in the figure,
each of which is equal to the figure of four feet?
Boy. True.
Soc. And is not that four times four?
Boy. Certainly.
Soc. And four times is not double?
Boy. No, indeed.
Soc. But how much?
Boy. Four times as much.
Soc. Therefore the double line, boy, has given a space,
not twice, but four times as much.
Boy. True.
Soc. Four times four are sixteen-are they
not?
Boy. Yes.
Soc. What line would give you a space of right feet, as
this gives one of sixteen feet;-do you see?
Boy. Yes.
Soc. And the space of four feet is made from this half
line?
Boy. Yes.
Soc. Good; and is not a space of eight feet twice the size
of this, and half the size of the other?
Boy. Certainly.
Soc. Such a space, then, will be made out of a line greater
than this one, and less than that one?
Boy. Yes; I think so.
Soc. Very good; I like to hear you say what you think. And
now tell me, is not this a line of two feet and that of
four?
Boy. Yes.
Soc. Then the line which forms the side of eight feet ought
to be more than this line of two feet, and less than the other of four
feet?
Boy. It ought.
Soc. Try and see if you can tell me how much it will
be.
Boy. Three feet.
Soc. Then if we add a half to this line of two, that will
be the line of three. Here are two and there is one; and on the other side,
here are two also and there is one: and that makes the figure of which
you speak?
Boy. Yes.
Soc. But if there are three feet this way and three feet
that way, the whole space will be three times three
feet?
Boy. That is evident.
Soc. And how much are three times three
feet?
Boy. Nine.
Soc. And how much is the double of four?
Boy. Eight.
Soc. Then the figure of eight is not made out of a of
three?
Boy. No.
Soc. But from what line?-tell me exactly; and if you would
rather not reckon, try and show me the line.
Boy. Indeed, Socrates, I do not know.
Soc. Do you see, Meno, what advances he has made in his
power of recollection? He did not know at first, and he does not know now,
what is the side of a figure of eight feet: but then he thought that he
knew, and answered confidently as if he knew, and had no difficulty; now
he has a difficulty, and neither knows nor fancies that he
knows.
Men. True.
Soc. Is he not better off in knowing his
ignorance?
Men. I think that he is.
Soc. If we have made him doubt, and given him the "torpedo's
shock," have we done him any harm?
Men. I think not.
Soc. We have certainly, as would seem, assisted him in some
degree to the discovery of the truth; and now he will wish to remedy his
ignorance, but then he would have been ready to tell all the world again
and again that the double space should have a double
side.
Men. True.
Soc. But do you suppose that he would ever have enquired
into or learned what he fancied that he knew, though he was really ignorant
of it, until he had fallen into perplexity under the idea that he did not
know, and had desired to know?
Men. I think not, Socrates.
Soc. Then he was the better for the torpedo's
touch?
Men. I think so.
Soc. Mark now the farther development. I shall only ask
him, and not teach him, and he shall share the enquiry with me: and do
you watch and see if you find me telling or explaining anything to him,
instead of eliciting his opinion. Tell me, boy, is not this a square of
four feet which I have drawn?
Boy. Yes.
Soc. And now I add another square equal to the former
one?
Boy. Yes.
Soc. And a third, which is equal to either of
them?
Boy. Yes.
Soc. Suppose that we fill up the vacant
corner?
Boy. Very good.
Soc. Here, then, there are four equal
spaces?
Boy. Yes.
Soc. And how many times larger is this space than this
other?
Boy. Four times.
Soc. But it ought to have been twice only, as you will
remember.
Boy. True.
Soc. And does not this line, reaching from corner to corner,
bisect each of these spaces?
Boy. Yes.
Soc. And are there not here four equal lines which contain
this space?
Boy. There are.
Soc. Look and see how much this space
is.
Boy. I do not understand.
Soc. Has not each interior line cut off half of the four
spaces?
Boy. Yes.
Soc. And how many spaces are there in this
section?
Boy. Four.
Soc. And how many in this?
Boy. Two.
Soc. And four is how many times two?
Boy. Twice.
Soc. And this space is of how many feet?
Boy. Of eight feet.
Soc. And from what line do you get this
figure?
Boy. From this.
Soc. That is, from the line which extends from corner to
corner of the figure of four feet?
Boy. Yes.
Soc. And that is the line which the learned call the diagonal.
And if this is the proper name, then you, Meno's slave, are prepared to
affirm that the double space is the square of the diagonal?
Boy. Certainly, Socrates.
Soc. What do you say of him, Meno? Were not all these answers
given out of his own head?
Men. Yes, they were all his own.
Soc. And yet, as we were just now saying, he did not
know?
Men. True.
Soc. But still he had in him those notions of his-had he
not?
Men. Yes.
Soc. Then he who does not know may still have true notions
of that which he does not know?
Men. He has.
Soc. And at present these notions have just been stirred
up in him, as in a dream; but if he were frequently asked the same questions,
in different forms, he would know as well as any one at
last?
Men. I dare say.
Soc. Without any one teaching him he will recover his knowledge
for himself, if he is only asked questions?
Men. Yes.
Soc. And this spontaneous recovery of knowledge in him is
recollection?
Men. True.
Soc. And this knowledge which he now has must he not either
have acquired or always possessed?
Men. Yes.
Soc. But if he always possessed this knowledge he would
always have known; or if he has acquired the knowledge he could not have
acquired it in this life, unless he has been taught geometry; for he may
be made to do the same with all geometry and every other branch of knowledge.
Now, has any one ever taught him all this? You must know about him, if,
as you say, he was born and bred in your house.
Men. And I am certain that no one ever did teach
him.
Soc. And yet he has the knowledge?
Men. The fact, Socrates, is undeniable.
Soc. But if he did not acquire the knowledge in this life,
then he must have had and learned it at some other time?
Men. Clearly he must.
