No More Learning

Very true, he said.
Then the wise or temperate man, and he only, will know himself, and
be able to examine what he knows or does not know, and to see what
others know and think that they know and do really know; and what
they do not know, and fancy that they know, when they do not. No other
person will be able to do this. And this is wisdom and temperance
and self-knowledge-for a man to know what he knows, and what he does
not know. That is your meaning?

Yes, he said.
Now then, I said, making an offering of the third or last argument
to Zeus the Saviour, let us begin again, and ask, in the first place,
whether it is or is not possible for a person to know that he knows
and does not know what he knows and does not know; and in the second
place, whether, if perfectly possible, such knowledge is of any use.

That is what we have to consider, he said.
And here, Critias, I said, I hope that you will find a way out of
a difficulty into which I have got myself. Shall I tell you the nature
of the difficulty?

By all means, he replied.
Does not what you have been saying, if true, amount to this: that
there must be a single science which is wholly a science of itself
and of other sciences, and that the same is also the science of the
absence of science?

Yes.
But consider how monstrous this proposition is, my friend: in any
parallel case, the impossibility will be transparent to you.

How is that? and in what cases do you mean?
In such cases as this: Suppose that there is a kind of vision which
is not like ordinary vision, but a vision of itself and of other sorts
of vision, and of the defect of them, which in seeing sees no colour,
but only itself and other sorts of vision: Do you think that there
is such a kind of vision?

Certainly not.
Or is there a kind of hearing which hears no sound at all, but only
itself and other sorts of hearing, or the defects of them?

There is not.
Or take all the senses: can you imagine that there is any sense of
itself and of other senses, but which is incapable of perceiving the
objects of the senses?

I think not.
Could there be any desire which is not the desire of any pleasure,
but of itself, and of all other desires?

Certainly not.
Or can you imagine a wish which wishes for no good, but only for itself
and all other wishes?

I should answer, No.
Or would you say that there is a love which is not the love of beauty,
but of itself and of other loves?

I should not.
Or did you ever know of a fear which fears itself or other fears,
but has no object of fear?

I never did, he said.
Or of an opinion which is an opinion of itself and of other opinions,
and which has no opinion on the subjects of opinion in general?

Certainly not.
But surely we are assuming a science of this kind, which, having no
subject-matter, is a science of itself and of the other sciences?

Yes, that is what is affirmed.
But how strange is this, if it be indeed true: must not however as
yet absolutely deny the possibility of such a science; let us rather
consider the matter.

You are quite right.
Well then, this science of which we are speaking is a science of something,
and is of a nature to be a science of something?

Yes.
Just as that which is greater is of a nature to be greater than something
else?

Yes.
Which is less, if the other is conceived to be greater?
To be sure.
And if we could find something which is at once greater than itself,
and greater than other great things, but not greater than those things
in comparison of which the others are greater, then that thing would
have the property of being greater and also less than itself?

That, Socrates, he said, is the inevitable inference.
Or if there be a double which is double of itself and of other doubles,
these will be halves; for the double is relative to the half?

That is true.
And that which is greater than itself will also be less, and that
which is heavier will also be lighter, and that which is older will
also be younger: and the same of other things; that which has a nature
relative to self will retain also the nature of its object: I mean
to say, for example, that hearing is, as we say, of sound or voice.
Is that true?

Yes.
Then if hearing hears itself, it must hear a voice; for there is no
other way of hearing.

Certainly.
And sight also, my excellent friend, if it sees itself must see a
colour, for sight cannot see that which has no colour.

No.
Do you remark, Critias, that in several of the examples which have
been recited the notion of a relation to self is altogether inadmissible,
and in other cases hardly credible-inadmissible, for example, in the
case of magnitudes, numbers, and the like?

Very true.
But in the case of hearing and sight, or in the power of self-motion,
and the power of heat to burn, this relation to self will be regarded
as incredible by some, but perhaps not by others. And some great man,
my friend, is wanted, who will satisfactorily determine for us, whether
there is nothing which has an inherent property of relation to self,
or some things only and not others; and whether in this class of self-related
things, if there be such a class, that science which is called wisdom
or temperance is included. I altogether distrust my own power of determining
these matters: I am not certain whether there is such a science of
science at all; and even if there be, I should not acknowledge this
to be wisdom or temperance, until I can also see whether such a science
would or would not do us any good; for I have an impression that temperance
is a benefit and a good. And therefore, O son of Callaeschrus, as
you maintain that temperance or wisdom is a science of science, and
also of the absence of science, I will request you to show in the
first place, as I was saying before, the possibility, and in the second
place, the advantage, of such a science; and then perhaps you may
satisfy me that you are right in your view of temperance.

Critias heard me say this, and saw that I was in a difficulty; and
as one person when another yawns in his presence catches the infection
of yawning from him, so did he seem to be driven into a difficulty
by my difficulty. But as he had a reputation to maintain, he was ashamed
to admit before the company that he could not answer my challenge
or determine the question at issue; and he made an unintelligible
attempt to hide his perplexity. In order that the argument might proceed,
I said to him, Well then Critias, if you like, let us assume that
there is this science of science; whether the assumption is right
or wrong may hereafter be investigated. Admitting the existence of
it, will you tell me how such a science enables us to distinguish
what we know or do not know, which, as we were saying, is self-knowledge
or wisdom: so we were saying?

Yes, Socrates, he said; and that I think is certainly true: for he
who has this science or knowledge which knows itself will become like
the knowledge which he has, in the same way that he who has swiftness
will be swift, and he who has beauty will be beautiful, and he who
has knowledge will know. In the same way he who has that knowledge
which is self-knowing, will know himself.

I do not doubt, I said, that a man will know himself, when he possesses
that which has self-knowledge: but what necessity is there that, having
this, he should know what he knows and what he does not know?

Because, Socrates, they are the same.
Very likely, I said; but I remain as stupid as ever; for still I fail
to comprehend how this knowing what you know and do not know is the
same as the knowledge of self.

What do you mean? he said.
This is what I mean, I replied: I will admit that there is a science
of science;-can this do more than determine that of two things one
is and the other is not science or knowledge?

No, just that.
But is knowledge or want of knowledge of health the same as knowledge
or want of knowledge of justice?

Certainly not.
The one is medicine, and the other is politics; whereas that of which
we are speaking is knowledge pure and simple.

Very true.
And if a man knows only, and has only knowledge of knowledge, and
has no further knowledge of health and justice, the probability is
that he will only know that he knows something, and has a certain
knowledge, whether concerning himself or other men.

True.
Then how will this knowledge or science teach him to know what he
knows? Say that he knows health;-not wisdom or temperance, but the
art of medicine has taught it to him; and he has learned harmony from
the art of music, and building from the art of building, neither,
from wisdom or temperance: and the same of other things.

That is evident.
How will wisdom, regarded only as a knowledge of knowledge or science
of science, ever teach him that he knows health, or that he knows
building?

It is impossible.
Then he who is ignorant of these things will only know that he knows,
but not what he knows?

True.
Then wisdom or being wise appears to be not the knowledge of the things
which we do or do not know, but only the knowledge that we know or
do not know?

That is the inference.
Then he who has this knowledge will not be able to examine whether
a pretender knows or does not know that which he says that he knows:
he will only know that he has a knowledge of some kind; but wisdom
will not show him of what the knowledge is?

Plainly not.
Neither will he be able to distinguish the pretender in medicine from
the true physician, nor between any other true and false professor
of knowledge. Let us consider the matter in this way: If the wise
man or any other man wants to distinguish the true physician from
the false, how will he proceed? He will not talk to him about medicine;
and that, as we were saying, is the only thing which the physician
understands.

True.
And, on the other hand, the physician knows nothing of science, for
this has been assumed to be the province of wisdom.

True.
And further, since medicine is science, we must infer that he does
not know anything of medicine.

Exactly.
Then the wise man may indeed know that the physician has some kind
of science or knowledge; but when he wants to discover the nature
of this he will ask, What is the subject-matter? For the several sciences
are distinguished not by the mere fact that they are sciences, but
by the nature of their subjects. Is not that true?

Quite true.
And medicine is distinguished from other sciences as having the subject-matter
of health and disease?

Yes.
And he who would enquire into the nature of medicine must pursue the
enquiry into health and disease, and not into what is extraneous?

True.
And he who judges rightly will judge of the physician as a physician
in what relates to these?

He will.
He will consider whether what he says is true, and whether what he
does is right, in relation to health and disease?

He will.
But can any one attain the knowledge of either unless he have a of
medicine?

He cannot.
No one at all, it would seem, except the physician can have this knowledge;
and therefore not the wise man; he would have to be a physician as
well as a wise man.

Very true.
Then, assuredly, wisdom or temperance, if only a science of science,
and of the absence of science or knowledge, will not be able to distinguish
the physician who knows from one who does not know but pretends or
thinks that he knows, or any other professor of anything at all; like
any other artist, he will only know his fellow in art or wisdom, and
no one else.

That is evident, he said.
But then what profit, Critias, I said, is there any longer in wisdom
or temperance which yet remains, if this is wisdom? If, indeed, as
we were supposing at first, the wise man had been able to distinguish
what he knew and did not know, and that he knew the one and did not
know the other, and to recognize a similar faculty of discernment
in others, there would certainly have been a great advantage in being
wise; for then we should never have made a mistake, but have passed
through life the unerring guides of ourselves and of those who are
under us; and we should not have attempted to do what we did not know,
but we should have found out those who knew, and have handed the business
over to them and trusted in them; nor should we have allowed those
who were under us to do anything which they were not likely to do
well and they would be likely to do well just that of which they had
knowledge; and the house or state which was ordered or administered
under the guidance of wisdom, and everything else of which wisdom
was the lord, would have been well ordered; for truth guiding, and
error having been eliminated, in all their doings, men would have
done well, and would have been happy. Was not this, Critias, what
we spoke of as the great advantage of wisdom to know what is known
and what is unknown to us?

Very true, he said.
And now you perceive, I said, that no such science is to be found
anywhere.

I perceive, he said.
May we assume then, I said, that wisdom, viewed in this new light
merely as a knowledge of knowledge and ignorance, has this advantage:-that
he who possesses such knowledge will more easily learn anything which
he learns; and that everything will be clearer to him, because, in
addition to the knowledge of individuals, he sees the science, and
this also will better enable him to test the knowledge which others
have of what he knows himself; whereas the enquirer who is without
this knowledge may be supposed to have a feebler and weaker insight?
Are not these, my friend, the real advantages which are to be gained
from wisdom? And are not we looking and seeking after something more
than is to be found in her?

That is very likely, he said.
That is very likely, I said; and very likely, too, we have been enquiring
to no purpose; as I am led to infer, because I observe that if this
is wisdom, some strange consequences would follow. Let us, if you
please, assume the possibility of this science of sciences, and further
admit and allow, as was originally suggested, that wisdom is the knowledge
of what we know and do not know. Assuming all this, still, upon further
consideration, I am doubtful, Critias, whether wisdom, such as this,
would do us much good. For we were wrong, I think, in supposing, as
we were saying just now, that such wisdom ordering the government
of house or state would be a great benefit.

How so? he said.
Why, I said, we were far too ready to admit the great benefits which
mankind would obtain from their severally doing the things which they
knew, and committing the things of which they are ignorant to those
who were better acquainted with them.

Were we not right in making that admission?
I think not.
How very strange, Socrates!
By the dog of Egypt, I said, there I agree with you; and I was thinking
as much just now when I said that strange consequences would follow,
and that I was afraid we were on the wrong track; for however ready
we may be to admit that this is wisdom, I certainly cannot make out
what good this sort of thing does to us.

What do you mean? he said; I wish that you could make me understand
what you mean.

I dare say that what I am saying is nonsense, I replied; and yet if
a man has any feeling of what is due to himself, he cannot let the
thought which comes into his mind pass away unheeded and unexamined.

I like that, he said.
Hear, then, I said, my own dream; whether coming through the horn
or the ivory gate, I cannot tell. The dream is this: Let us suppose
that wisdom is such as we are now defining, and that she has absolute
sway over us; then each action will be done according to the arts
or sciences, and no one professing to be a pilot when he is not, or
any physician or general, or any one else pretending to know matters
of which he is ignorant, will deceive or elude us; our health will
be improved; our safety at sea, and also in battle, will be assured;
our coats and shoes, and all other instruments and implements will
be skilfully made, because the workmen will be good and true. Aye,
and if you please, you may suppose that prophecy, which is the knowledge
of the future, will be under the control of wisdom, and that she will
deter deceivers and set up the true prophets in their place as the
revealers of the future. Now I quite agree that mankind, thus provided,
would live and act according to knowledge, for wisdom would watch
and prevent ignorance from intruding on us. But whether by acting
according to knowledge we shall act well and be happy, my dear Critias,-this
is a point which we have not yet been able to determine.

Yet I think, he replied, that if you discard knowledge, you will hardly
find the crown of happiness in anything else.

But of what is this knowledge? I said. Just answer me that small question.
Do you mean a knowledge of shoemaking?

God forbid.
Or of working in brass?
Certainly not.
Or in wool, or wood, or anything of that sort?
No, I do not.
Then, I said, we are giving up the doctrine that he who lives according
to knowledge is happy, for these live according to knowledge, and
yet they are not allowed by you to be happy; but I think that you
mean to confine happiness to particular individuals who live according
to knowledge, such for example as the prophet, who, as I was saying,
knows the future. Is it of him you are speaking or of some one else?

Yes, I mean him, but there are others as well.
Yes, I said, some one who knows the past and present as well as the
future, and is ignorant of nothing. Let us suppose that there is such
a person, and if there is, you will allow that he is the most knowing
of all living men.

Certainly he is.
Yet I should like to know one thing more: which of the different kinds
of knowledge makes him happy? or do all equally make him happy?

Not all equally, he replied.
But which most tends to make him happy? the knowledge of what past,
present, or future thing? May I infer this to be the knowledge of
the game of draughts?

Nonsense about the game of draughts.
Or of computation?
No.
Or of health?
That is nearer the truth, he said.
And that knowledge which is nearest of all, I said, is the knowledge
of what?

The knowledge with which he discerns good and evil.
Monster! I said; you have been carrying me round in a circle, and
all this time hiding from me the fact that the life according to knowledge
is not that which makes men act rightly and be happy, not even if
knowledge include all the sciences, but one science only, that of
good and evil. For, let me ask you, Critias, whether, if you take
away this, medicine will not equally give health, and shoemaking equally
produce shoes, and the art of the weaver clothes? -whether the art
of the pilot will not equally save our lives at sea, and the art of
the general in war?

Quite so.
And yet, my dear Critias, none of these things will be well or beneficially
done, if the science of the good be wanting.

True.
But that science is not wisdom or temperance, but a science of human
advantage; not a science of other sciences, or of ignorance, but of
good and evil: and if this be of use, then wisdom or temperance will
not be of use.

And why, he replied, will not wisdom be of use? For, however much
we assume that wisdom is a science of sciences, and has a sway over
other sciences, surely she will have this particular science of the
good under her control, and in this way will benefit us.

And will wisdom give health? I said; is not this rather the effect
of medicine? Or does wisdom do the work any of the other arts, do
they not each of them do their own work? Have we not long ago asseverated
that wisdom is only the knowledge of knowledge and of ignorance, and
of nothing else?

That is obvious.
Then wisdom will not be the producer of health.
Certainly not.
The art of health is different.
Yes, different.
Nor does wisdom give advantage, my good friend; for that again we
have just now been attributing to another art.

Very true.
How then can wisdom be advantageous, when giving no advantage?

That, Socrates, is certainly inconceivable.
You see then, Critias, that I was not far wrong in fearing that I
could have no sound notion about wisdom; I was quite right in depreciating
myself; for that which is admitted to be the best of all things would
never have seemed to us useless, if I had been good for anything at
an enquiry. But now I have been utterly defeated, and have failed
to discover what that is to which the imposer of names gave this name
of temperance or wisdom. And yet many more admissions were made by
us than could be fairly granted; for we admitted that there was a
science of science, although the argument said No, and protested against
us; and we admitted further, that this science knew the works of the
other sciences (although this too was denied by the argument), because
we wanted to show that the wise man had knowledge of what he knew
and did not know; also we nobly disregarded, and never even considered,
the impossibility of a man knowing in a sort of way that which he
does not know at all; for our assumption was, that he knows that which
he does not know; than which nothing, as I think, can be more irrational.
And yet, after finding us so easy and good-natured, the enquiry is
still unable to discover the truth; but mocks us to a degree, and
has gone out of its way to prove the inutility of that which we admitted
only by a sort of supposition and fiction to be the true definition
of temperance or wisdom: which result, as far as I am concerned, is
not so much to be lamented, I said. But for your sake, Charmides,
I am very sorry-that you, having such beauty and such wisdom and temperance
of soul, should have no profit or good in life from your wisdom and
temperance. And still more am I grieved about the charm which I learned
with so much pain, and to so little profit, from the Thracian, for
the sake of a thing which is nothing worth. I think indeed that there
is a mistake, and that I must be a bad enquirer, for wisdom or temperance
I believe to be really a great good; and happy are you, Charmides,
if you certainly possess it. Wherefore examine yourself, and see whether
you have this gift and can do without the charm; for if you can, I
would rather advise you to regard me simply as a fool who is never
able to reason out anything; and to rest assured that the more wise
and temperate you are, the happier you will be.

Charmides said: I am sure that I do not know, Socrates, whether I
have or have not this gift of wisdom and temperance; for how can I
know whether I have a thing, of which even you and Critias are, as
you say, unable to discover the nature? -(not that I believe you. )
And further, I am sure, Socrates, that I do need the charm, and as
far as I am concerned, I shall be willing to be charmed by you daily,
until you say that I have had enough.

Very good, Charmides, said Critias; if you do this I shall have a
proof of your temperance, that is, if you allow yourself to be charmed
by Socrates, and never desert him at all.

You may depend on my following and not deserting him, said Charmides:
if you who are my guardian command me, I should be very wrong not
to obey you.

And I do command you, he said.
Then I will do as you say, and begin this very day.
You sirs, I said, what are you conspiring about?
We are not conspiring, said Charmides, we have conspired already.

And are you about to use violence, without even going through the
forms of justice?

Yes, I shall use violence, he replied, since he orders me; and therefore
you had better consider well.

But the time for consideration has passed, I said, when violence is
employed; and you, when you are determined on anything, and in the
mood of violence, are irresistible.

Do not you resist me then, he said.
I will not resist you, I replied.
