Since we have previously said that one ought to choose that which 
is intermediate, not the excess nor the defect, and that the intermediate 
is determined by the dictates of the right rule, let us discuss the nature 
of these dictates. In all the states of character we have mentioned, as 
in all other matters, there is a mark to which the man who has the rule 
looks, and heightens or relaxes his activity accordingly, and there is 
a standard which determines the mean states which we say are intermediate 
between excess and defect, being in accordance with the right rule. But 
such a statement, though true, is by no means clear; for not only here 
but in all other pursuits which are objects of knowledge it is indeed true 
to say that we must not exert ourselves nor relax our efforts too much 
nor too little, but to an intermediate extent and as the right rule dictates; 
but if a man had only this knowledge he would be none the wiser e.g. we 
should not know what sort of medicines to apply to our body if some one 
were to say 'all those which the medical art prescribes, and which agree 
with the practice of one who possesses the art'. Hence it is necessary 
with regard to the states of the soul also not only that this true statement 
should be made, but also that it should be determined what is the right 
rule and what is the standard that fixes it.
We divided the virtues of the soul and a said that some are virtues 
of character and others of intellect. Now we have discussed in detail the 
moral virtues; with regard to the others let us express our view as follows, 
beginning with some remarks about the soul. We said before that there are 
two parts of the soul-that which grasps a rule or rational principle, and 
the irrational; let us now draw a similar distinction within the part which 
grasps a rational principle. And let it be assumed that there are two parts 
which grasp a rational principle-one by which we contemplate the kind of 
things whose originative causes are invariable, and one by which we contemplate 
variable things; for where objects differ in kind the part of the soul 
answering to each of the two is different in kind, since it is in virtue 
of a certain likeness and kinship with their objects that they have the 
knowledge they have. Let one of these parts be called the scientific and 
the other the calculative; for to deliberate and to calculate are the same 
thing, but no one deliberates about the invariable. Therefore the calculative 
is one part of the faculty which grasps a rational principle. We must, 
then, learn what is the best state of each of these two parts; for this 
is the virtue of each.
2
The virtue of a thing is relative to its proper work. Now there 
are three things in the soul which control action and truth-sensation, 
reason, desire.
Of these sensation originates no action; this is plain from the 
fact that the lower animals have sensation but no share in 
action.
What affirmation and negation are in thinking, pursuit and avoidance 
are in desire; so that since moral virtue is a state of character concerned 
with choice, and choice is deliberate desire, therefore both the reasoning 
must be true and the desire right, if the choice is to be good, and the 
latter must pursue just what the former asserts. Now this kind of intellect 
and of truth is practical; of the intellect which is contemplative, not 
practical nor productive, the good and the bad state are truth and falsity 
respectively (for this is the work of everything intellectual); while of 
the part which is practical and intellectual the good state is truth in 
agreement with right desire.
The origin of action-its efficient, not its final cause-is choice, 
and that of choice is desire and reasoning with a view to an end. This 
is why choice cannot exist either without reason and intellect or without 
a moral state; for good action and its opposite cannot exist without a 
combination of intellect and character. Intellect itself, however, moves 
nothing, but only the intellect which aims at an end and is practical; 
for this rules the productive intellect, as well, since every one who makes 
makes for an end, and that which is made is not an end in the unqualified 
sense (but only an end in a particular relation, and the end of a particular 
operation)-only that which is done is that; for good action is an end, 
and desire aims at this. Hence choice is either desiderative reason or 
ratiocinative desire, and such an origin of action is a man. (It is to 
be noted that nothing that is past is an object of choice, e.g. no one 
chooses to have sacked Troy; for no one deliberates about the past, but 
about what is future and capable of being otherwise, while what is past 
is not capable of not having taken place; hence Agathon is right in 
saying
For this alone is lacking even to God,
To make undone things thathave once been done.)
The work of both the intellectual parts, then, is truth. Therefore 
the states that are most strictly those in respect of which each of these 
parts will reach truth are the virtues of the two parts.
3
Let us begin, then, from the beginning, and discuss these states 
once more. Let it be assumed that the states by virtue of which the soul 
possesses truth by way of affirmation or denial are five in number, i.e. 
art, scientific knowledge, practical wisdom, philosophic wisdom, intuitive 
reason; we do not include judgement and opinion because in these we may 
be mistaken.
Now what scientific knowledge is, if we are to speak exactly and 
not follow mere similarities, is plain from what follows. We all suppose 
that what we know is not even capable of being otherwise; of things capable 
of being otherwise we do not know, when they have passed outside our observation, 
whether they exist or not. Therefore the object of scientific knowledge 
is of necessity. Therefore it is eternal; for things that are of necessity 
in the unqualified sense are all eternal; and things that are eternal are 
ungenerated and imperishable. Again, every science is thought to be capable 
of being taught, and its object of being learned. And all teaching starts 
from what is already known, as we maintain in the Analytics also; for it 
proceeds sometimes through induction and sometimes by syllogism. Now induction 
is the starting-point which knowledge even of the universal presupposes, 
while syllogism proceeds from universals. There are therefore starting-points 
from which syllogism proceeds, which are not reached by syllogism; it is 
therefore by induction that they are acquired. Scientific knowledge is, 
then, a state of capacity to demonstrate, and has the other limiting characteristics 
which we specify in the Analytics, for it is when a man believes in a certain 
way and the starting-points are known to him that he has scientific knowledge, 
since if they are not better known to him than the conclusion, he will 
have his knowledge only incidentally.
Let this, then, be taken as our account of scientific 
knowledge.
4
In the variable are included both things made and things done; 
making and acting are different (for their nature we treat even the discussions 
outside our school as reliable); so that the reasoned state of capacity 
to act is different from the reasoned state of capacity to make. Hence 
too they are not included one in the other; for neither is acting making 
nor is making acting. Now since architecture is an art and is essentially 
a reasoned state of capacity to make, and there is neither any art that 
is not such a state nor any such state that is not an art, art is identical 
with a state of capacity to make, involving a true course of reasoning. 
All art is concerned with coming into being, i.e. with contriving and considering 
how something may come into being which is capable of either being or not 
being, and whose origin is in the maker and not in the thing made; for 
art is concerned neither with things that are, or come into being, by necessity, 
nor with things that do so in accordance with nature (since these have 
their origin in themselves). Making and acting being different, art must 
be a matter of making, not of acting. And in a sense chance and art are 
concerned with the same objects; as Agathon says, 'art loves chance and 
chance loves art'. Art, then, as has been is a state concerned with making, 
involving a true course of reasoning, and lack of art on the contrary is 
a state concerned with making, involving a false course of reasoning; both 
are concerned with the variable.
5
Regarding practical wisdom we shall get at the truth by considering 
who are the persons we credit with it. Now it is thought to be the mark 
of a man of practical wisdom to be able to deliberate well about what is 
good and expedient for himself, not in some particular respect, e.g. about 
what sorts of thing conduce to health or to strength, but about what sorts 
of thing conduce to the good life in general. This is shown by the fact 
that we credit men with practical wisdom in some particular respect when 
they have calculated well with a view to some good end which is one of 
those that are not the object of any art. It follows that in the general 
sense also the man who is capable of deliberating has practical wisdom. 
Now no one deliberates about things that are invariable, nor about things 
that it is impossible for him to do. Therefore, since scientific knowledge 
involves demonstration, but there is no demonstration of things whose first 
principles are variable (for all such things might actually be otherwise), 
and since it is impossible to deliberate about things that are of necessity, 
practical wisdom cannot be scientific knowledge nor art; not science because 
that which can be done is capable of being otherwise, not art because action 
and making are different kinds of thing. The remaining alternative, then, 
is that it is a true and reasoned state of capacity to act with regard 
to the things that are good or bad for man. For while making has an end 
other than itself, action cannot; for good action itself is its end. It 
is for this reason that we think Pericles and men like him have practical 
wisdom, viz. because they can see what is good for themselves and what 
is good for men in general; we consider that those can do this who are 
good at managing households or states. (This is why we call temperance 
(sophrosune) by this name; we imply that it preserves one's practical wisdom 
(sozousa tan phronsin). Now what it preserves is a judgement of the kind 
we have described. For it is not any and every judgement that pleasant 
and painful objects destroy and pervert, e.g. the judgement that the triangle 
has or has not its angles equal to two right angles, but only judgements 
about what is to be done. For the originating causes of the things that 
are done consist in the end at which they are aimed; but the man who has 
been ruined by pleasure or pain forthwith fails to see any such originating 
cause-to see that for the sake of this or because of this he ought to choose 
and do whatever he chooses and does; for vice is destructive of the originating 
cause of action.) Practical wisdom, then, must be a reasoned and true state 
of capacity to act with regard to human goods. But further, while there 
is such a thing as excellence in art, there is no such thing as excellence 
in practical wisdom; and in art he who errs willingly is preferable, but 
in practical wisdom, as in the virtues, he is the reverse. Plainly, then, 
practical wisdom is a virtue and not an art. There being two parts of the 
soul that can follow a course of reasoning, it must be the virtue of one 
of the two, i.e. of that part which forms opinions; for opinion is about 
the variable and so is practical wisdom. But yet it is not only a reasoned 
state; this is shown by the fact that a state of that sort may forgotten 
but practical wisdom cannot.
6
Scientific knowledge is judgement about things that are universal 
and necessary, and the conclusions of demonstration, and all scientific 
knowledge, follow from first principles (for scientific knowledge involves 
apprehension of a rational ground). This being so, the first principle 
from which what is scientifically known follows cannot be an object of 
scientific knowledge, of art, or of practical wisdom; for that which can 
be scientifically known can be demonstrated, and art and practical wisdom 
deal with things that are variable. Nor are these first principles the 
objects of philosophic wisdom, for it is a mark of the philosopher to have 
demonstration about some things. If, then, the states of mind by which 
we have truth and are never deceived about things invariable or even variable 
are scientific knowlededge, practical wisdom, philosophic wisdom, and intuitive 
reason, and it cannot be any of the three (i.e. practical wisdom, scientific 
knowledge, or philosophic wisdom), the remaining alternative is that it 
is intuitive reason that grasps the first principles.
7
Wisdom (1) in the arts we ascribe to their most finished exponents, 
e.g. to Phidias as a sculptor and to Polyclitus as a maker of portrait-statues, 
and here we mean nothing by wisdom except excellence in art; but (2) we 
think that some people are wise in general, not in some particular field 
or in any other limited respect, as Homer says in the 
Margites,
Him did the gods make neither a digger nor yet a 
ploughman
Nor wise in anything else. Therefore wisdom must plainly be the most 
finished of the forms of knowledge. It follows that the wise man must not 
only know what follows from the first principles, but must also possess 
truth about the first principles. Therefore wisdom must be intuitive reason 
combined with scientific knowledge-scientific knowledge of the highest 
objects which has received as it were its proper completion.
Of the highest objects, we say; for it would be strange to think 
that the art of politics, or practical wisdom, is the best knowledge, since 
man is not the best thing in the world. Now if what is healthy or good 
is different for men and for fishes, but what is white or straight is always 
the same, any one would say that what is wise is the same but what is practically 
wise is different; for it is to that which observes well the various matters 
concerning itself that one ascribes practical wisdom, and it is to this 
that one will entrust such matters. This is why we say that some even of 
the lower animals have practical wisdom, viz. those which are found to 
have a power of foresight with regard to their own life. It is evident 
also that philosophic wisdom and the art of politics cannot be the same; 
for if the state of mind concerned with a man's own interests is to be 
called philosophic wisdom, there will be many philosophic wisdoms; there 
will not be one concerned with the good of all animals (any more than there 
is one art of medicine for all existing things), but a different philosophic 
wisdom about the good of each species.
But if the argument be that man is the best of the animals, this 
makes no difference; for there are other things much more divine in their 
nature even than man, e.g., most conspicuously, the bodies of which the 
heavens are framed. From what has been said it is plain, then, that philosophic 
wisdom is scientific knowledge, combined with intuitive reason, of the 
things that are highest by nature. This is why we say Anaxagoras, Thales, 
and men like them have philosophic but not practical wisdom, when we see 
them ignorant of what is to their own advantage, and why we say that they 
know things that are remarkable, admirable, difficult, and divine, but 
useless; viz. because it is not human goods that they 
seek.
Practical wisdom on the other hand is concerned with things human 
and things about which it is possible to deliberate; for we say this is 
above all the work of the man of practical wisdom, to deliberate well, 
but no one deliberates about things invariable, nor about things which 
have not an end, and that a good that can be brought about by action. The 
man who is without qualification good at deliberating is the man who is 
capable of aiming in accordance with calculation at the best for man of 
things attainable by action. Nor is practical wisdom concerned with universals 
only-it must also recognize the particulars; for it is practical, and practice 
is concerned with particulars. This is why some who do not know, and especially 
those who have experience, are more practical than others who know; for 
if a man knew that light meats are digestible and wholesome, but did not 
know which sorts of meat are light, he would not produce health, but the 
man who knows that chicken is wholesome is more likely to produce 
health.
Now practical wisdom is concerned with action; therefore one should 
have both forms of it, or the latter in preference to the former. But of 
practical as of philosophic wisdom there must be a controlling 
kind.
8
Political wisdom and practical wisdom are the same state of mind, 
but their essence is not the same. Of the wisdom concerned with the city, 
the practical wisdom which plays a controlling part is legislative wisdom, 
while that which is related to this as particulars to their universal is 
known by the general name 'political wisdom'; this has to do with action 
and deliberation, for a decree is a thing to be carried out in the form 
of an individual act. This is why the exponents of this art are alone said 
to 'take part in politics'; for these alone 'do things' as manual labourers 
'do things'.
Practical wisdom also is identified especially with that form of 
it which is concerned with a man himself-with the individual; and this 
is known by the general name 'practical wisdom'; of the other kinds one 
is called household management, another legislation, the third politics, 
and of the latter one part is called deliberative and the other judicial. 
Now knowing what is good for oneself will be one kind of knowledge, but 
it is very different from the other kinds; and the man who knows and concerns 
himself with his own interests is thought to have practical wisdom, while 
politicians are thought to be busybodies; hence the word of 
Euripides,
But how could I be wise, who might at ease,
Numbered among the army's multitude,
Have had an equal share?
For those who aim too high and do too much. Those who think thus seek 
their own good, and consider that one ought to do so. From this opinion, 
then, has come the view that such men have practical wisdom; yet perhaps 
one's own good cannot exist without household management, nor without a 
form of government. Further, how one should order one's own affairs is 
not clear and needs inquiry.
What has been said is confirmed by the fact that while young men 
become geometricians and mathematicians and wise in matters like these, 
it is thought that a young man of practical wisdom cannot be found. The 
cause is that such wisdom is concerned not only with universals but with 
particulars, which become familiar from experience, but a young man has 
no experience, for it is length of time that gives experience; indeed one 
might ask this question too, why a boy may become a mathematician, but 
not a philosopher or a physicist. It is because the objects of mathematics 
exist by abstraction, while the first principles of these other subjects 
come from experience, and because young men have no conviction about the 
latter but merely use the proper language, while the essence of mathematical 
objects is plain enough to them?
Further, error in deliberation may be either about the universal 
or about the particular; we may fall to know either that all water that 
weighs heavy is bad, or that this particular water weighs 
heavy.
That practical wisdom is not scientific knowledge is evident; for 
it is, as has been said, concerned with the ultimate particular fact, since 
the thing to be done is of this nature. It is opposed, then, to intuitive 
reason; for intuitive reason is of the limiting premisses, for which no 
reason can be given, while practical wisdom is concerned with the ultimate 
particular, which is the object not of scientific knowledge but of perception-not 
the perception of qualities peculiar to one sense but a perception akin 
to that by which we perceive that the particular figure before us is a 
triangle; for in that direction as well as in that of the major premiss 
there will be a limit. But this is rather perception than practical wisdom, 
though it is another kind of perception than that of the qualities peculiar 
to each sense.
9
There is a difference between inquiry and deliberation; for deliberation 
is inquiry into a particular kind of thing. We must grasp the nature of 
excellence in deliberation as well whether it is a form of scientific knowledge, 
or opinion, or skill in conjecture, or some other kind of thing. Scientific 
knowledge it is not; for men do not inquire about the things they know 
about, but good deliberation is a kind of deliberation, and he who deliberates 
inquires and calculates. Nor is it skill in conjecture; for this both involves 
no reasoning and is something that is quick in its operation, while men 
deliberate a long time, and they say that one should carry out quickly 
the conclusions of one's deliberation, but should deliberate slowly. Again, 
readiness of mind is different from excellence in deliberation; it is a 
sort of skill in conjecture. Nor again is excellence in deliberation opinion 
of any sort. But since the man who deliberates badly makes a mistake, while 
he who deliberates well does so correctly, excellence in deliberation is 
clearly a kind of correctness, but neither of knowledge nor of opinion; 
for there is no such thing as correctness of knowledge (since there is 
no such thing as error of knowledge), and correctness of opinion is truth; 
and at the same time everything that is an object of opinion is already 
determined. But again excellence in deliberation involves reasoning. The 
remaining alternative, then, is that it is correctness of thinking; for 
this is not yet assertion, since, while even opinion is not inquiry but 
has reached the stage of assertion, the man who is deliberating, whether 
he does so well or ill, is searching for something and 
calculating.
But excellence in deliberation is a certain correctness of deliberation; 
hence we must first inquire what deliberation is and what it is about. 
And, there being more than one kind of correctness, plainly excellence 
in deliberation is not any and every kind; for (1) the incontinent man 
and the bad man, if he is clever, will reach as a result of his calculation 
what he sets before himself, so that he will have deliberated correctly, 
but he will have got for himself a great evil. Now to have deliberated 
well is thought to be a good thing; for it is this kind of correctness 
of deliberation that is excellence in deliberation, viz. that which tends 
to attain what is good. But (2) it is possible to attain even good by a 
false syllogism, and to attain what one ought to do but not by the right 
means, the middle term being false; so that this too is not yet excellence 
in deliberation this state in virtue of which one attains what one ought 
but not by the right means. Again (3) it is possible to attain it by long 
deliberation while another man attains it quickly. Therefore in the former 
case we have not yet got excellence in deliberation, which is rightness 
with regard to the expedient-rightness in respect both of the end, the 
manner, and the time. (4) Further it is possible to have deliberated well 
either in the unqualified sense or with reference to a particular end. 
Excellence in deliberation in the unqualified sense, then, is that which 
succeeds with reference to what is the end in the unqualified sense, and 
excellence in deliberation in a particular sense is that which succeeds 
relatively to a particular end. If, then, it is characteristic of men of 
practical wisdom to have deliberated well, excellence in deliberation will 
be correctness with regard to what conduces to the end of which practical 
wisdom is the true apprehension.
10
Understanding, also, and goodness of understanding, in virtue of 
which men are said to be men of understanding or of good understanding, 
are neither entirely the same as opinion or scientific knowledge (for at 
that rate all men would have been men of understanding), nor are they one 
of the particular sciences, such as medicine, the science of things connected 
with health, or geometry, the science of spatial magnitudes. For understanding 
is neither about things that are always and are unchangeable, nor about 
any and every one of the things that come into being, but about things 
which may become subjects of questioning and deliberation. Hence it is 
about the same objects as practical wisdom; but understanding and practical 
wisdom are not the same. For practical wisdom issues commands, since its 
end is what ought to be done or not to be done; but understanding only 
judges. (Understanding is identical with goodness of understanding, men 
of understanding with men of good understanding.) Now understanding is 
neither the having nor the acquiring of practical wisdom; but as learning 
is called understanding when it means the exercise of the faculty of knowledge, 
so 'understanding' is applicable to the exercise of the faculty of opinion 
for the purpose of judging of what some one else says about matters with 
which practical wisdom is concerned-and of judging soundly; for 'well' 
and 'soundly' are the same thing. And from this has come the use of the 
name 'understanding' in virtue of which men are said to be 'of good understanding', 
viz. from the application of the word to the grasping of scientific truth; 
for we often call such grasping understanding.
11
What is called judgement, in virtue of which men are said to 'be 
sympathetic judges' and to 'have judgement', is the right discrimination 
of the equitable. This is shown by the fact that we say the equitable man 
is above all others a man of sympathetic judgement, and identify equity 
with sympathetic judgement about certain facts. And sympathetic judgement 
is judgement which discriminates what is equitable and does so correctly; 
and correct judgement is that which judges what is true.
Now all the states we have considered converge, as might be expected, 
to the same point; for when we speak of judgement and understanding and 
practical wisdom and intuitive reason we credit the same people with possessing 
judgement and having reached years of reason and with having practical 
wisdom and understanding. For all these faculties deal with ultimates, 
i.e. with particulars; and being a man of understanding and of good or 
sympathetic judgement consists in being able judge about the things with 
which practical wisdom is concerned; for the equities are common to all 
good men in relation to other men. Now all things which have to be done 
are included among particulars or ultimates; for not only must the man 
of practical wisdom know particular facts, but understanding and judgement 
are also concerned with things to be done, and these are ultimates. And 
intuitive reason is concerned with the ultimates in both directions; for 
both the first terms and the last are objects of intuitive reason and not 
of argument, and the intuitive reason which is presupposed by demonstrations 
grasps the unchangeable and first terms, while the intuitive reason involved 
in practical reasonings grasps the last and variable fact, i.e. the minor 
premiss. For these variable facts are the starting-points for the apprehension 
of the end, since the universals are reached from the particulars; of these 
therefore we must have perception, and this perception is intuitive 
reason.
This is why these states are thought to be natural endowments-why, 
while no one is thought to be a philosopher by nature, people are thought 
to have by nature judgement, understanding, and intuitive reason. This 
is shown by the fact that we think our powers correspond to our time of 
life, and that a particular age brings with it intuitive reason and judgement; 
this implies that nature is the cause. (Hence intuitive reason is both 
beginning and end; for demonstrations are from these and about these.) 
Therefore we ought to attend to the undemonstrated sayings and opinions 
of experienced and older people or of people of practical wisdom not less 
than to demonstrations; for because experience has given them an eye they 
see aright.
We have stated, then, what practical and philosophic wisdom are, 
and with what each of them is concerned, and we have said that each is 
the virtue of a different part of the soul.
12
Difficulties might be raised as to the utility of these qualities 
of mind. For (1) philosophic wisdom will contemplate none of the things 
that will make a man happy (for it is not concerned with any coming into 
being), and though practical wisdom has this merit, for what purpose do 
we need it? Practical wisdom is the quality of mind concerned with things 
just and noble and good for man, but these are the things which it is the 
mark of a good man to do, and we are none the more able to act for knowing 
them if the virtues are states of character, just as we are none the better 
able to act for knowing the things that are healthy and sound, in the sense 
not of producing but of issuing from the state of health; for we are none 
the more able to act for having the art of medicine or of gymnastics. But 
(2) if we are to say that a man should have practical wisdom not for the 
sake of knowing moral truths but for the sake of becoming good, practical 
wisdom will be of no use to those who are good; again it is of no use to 
those who have not virtue; for it will make no difference whether they 
have practical wisdom themselves or obey others who have it, and it would 
be enough for us to do what we do in the case of health; though we wish 
to become healthy, yet we do not learn the art of medicine. (3) Besides 
this, it would be thought strange if practical wisdom, being inferior to 
philosophic wisdom, is to be put in authority over it, as seems to be implied 
by the fact that the art which produces anything rules and issues commands 
about that thing.
These, then, are the questions we must discuss; so far we have 
only stated the difficulties.
(1) Now first let us say that in themselves these states must be 
worthy of choice because they are the virtues of the two parts of the soul 
respectively, even if neither of them produce anything.
(2) Secondly, they do produce something, not as the art of medicine 
produces health, however, but as health produces health; so does philosophic 
wisdom produce happiness; for, being a part of virtue entire, by being 
possessed and by actualizing itself it makes a man happy.
(3) Again, the work of man is achieved only in accordance with 
practical wisdom as well as with moral virtue; for virtue makes us aim 
at the right mark, and practical wisdom makes us take the right means. 
(Of the fourth part of the soul-the nutritive-there is no such virtue; 
for there is nothing which it is in its power to do or not to 
do.)
(4) With regard to our being none the more able to do because of 
our practical wisdom what is noble and just, let us begin a little further 
back, starting with the following principle. As we say that some people 
who do just acts are not necessarily just, i.e. those who do the acts ordained 
by the laws either unwillingly or owing to ignorance or for some other 
reason and not for the sake of the acts themselves (though, to be sure, 
they do what they should and all the things that the good man ought), so 
is it, it seems, that in order to be good one must be in a certain state 
when one does the several acts, i.e. one must do them as a result of choice 
and for the sake of the acts themselves. Now virtue makes the choice right, 
but the question of the things which should naturally be done to carry 
out our choice belongs not to virtue but to another faculty. We must devote 
our attention to these matters and give a clearer statement about them. 
There is a faculty which is called cleverness; and this is such as to be 
able to do the things that tend towards the mark we have set before ourselves, 
and to hit it. Now if the mark be noble, the cleverness is laudable, but 
if the mark be bad, the cleverness is mere smartness; hence we call even 
men of practical wisdom clever or smart. Practical wisdom is not the faculty, 
but it does not exist without this faculty. And this eye of the soul acquires 
its formed state not without the aid of virtue, as has been said and is 
plain; for the syllogisms which deal with acts to be done are things which 
involve a starting-point, viz. 'since the end, i.e. what is best, is of 
such and such a nature', whatever it may be (let it for the sake of argument 
be what we please); and this is not evident except to the good man; for 
wickedness perverts us and causes us to be deceived about the starting-points 
of action. Therefore it is evident that it is impossible to be practically 
wise without being good.

We must therefore consider virtue also once more; for virtue too 
is similarly related; as practical wisdom is to cleverness-not the same, 
but like it-so is natural virtue to virtue in the strict sense. For all 
men think that each type of character belongs to its possessors in some 
sense by nature; for from the very moment of birth we are just or fitted 
for selfcontrol or brave or have the other moral qualities; but yet we 
seek something else as that which is good in the strict sense-we seek for 
the presence of such qualities in another way. For both children and brutes 
have the natural dispositions to these qualities, but without reason these 
are evidently hurtful. Only we seem to see this much, that, while one may 
be led astray by them, as a strong body which moves without sight may stumble 
badly because of its lack of sight, still, if a man once acquires reason, 
that makes a difference in action; and his state, while still like what 
it was, will then be virtue in the strict sense. Therefore, as in the part 
of us which forms opinions there are two types, cleverness and practical 
wisdom, so too in the moral part there are two types, natural virtue and 
virtue in the strict sense, and of these the latter involves practical 
wisdom. This is why some say that all the virtues are forms of practical 
wisdom, and why Socrates in one respect was on the right track while in 
another he went astray; in thinking that all the virtues were forms of 
practical wisdom he was wrong, but in saying they implied practical wisdom 
he was right. This is confirmed by the fact that even now all men, when 
they define virtue, after naming the state of character and its objects 
add 'that (state) which is in accordance with the right rule'; now the 
right rule is that which is in accordance with practical wisdom. All men, 
then, seem somehow to divine that this kind of state is virtue, viz. that 
which is in accordance with practical wisdom. But we must go a little further. 
For it is not merely the state in accordance with the right rule, but the 
state that implies the presence of the right rule, that is virtue; and 
practical wisdom is a right rule about such matters. Socrates, then, thought 
the virtues were rules or rational principles (for he thought they were, 
all of them, forms of scientific knowledge), while we think they involve 
a rational principle.
It is clear, then, from what has been said, that it is not possible 
to be good in the strict sense without practical wisdom, nor practically 
wise without moral virtue. But in this way we may also refute the dialectical 
argument whereby it might be contended that the virtues exist in separation 
from each other; the same man, it might be said, is not best equipped by 
nature for all the virtues, so that he will have already acquired one when 
he has not yet acquired another. This is possible in respect of the natural 
virtues, but not in respect of those in respect of which a man is called 
without qualification good; for with the presence of the one quality, practical 
wisdom, will be given all the virtues. And it is plain that, even if it 
were of no practical value, we should have needed it because it is the 
virtue of the part of us in question; plain too that the choice will not 
be right without practical wisdom any more than without virtue; for the 
one deter, mines the end and the other makes us do the things that lead 
to the end.
But again it is not supreme over philosophic wisdom, i.e. over 
the superior part of us, any more than the art of medicine is over health; 
for it does not use it but provides for its coming into being; it issues 
orders, then, for its sake, but not to it. Further, to maintain its supremacy 
would be like saying that the art of politics rules the gods because it 
issues orders about all the affairs of the state.
