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.
