Raphael, The School of Athens, 1509. Detail of Plato and Aristotle. What we are seeing is
a debate between student and teacher.
The gesture represented by Plato pointing upwards because he is known as the author
of the “Theory of Forms”.
o Work of philosophy is to discover those.
General themes= what you would consider being the soul would be corrupted by the
embodiment (rational part of the soul). Rational part needs to out rule the other parts
of the soul.
In general, Plato describes justice as: Everyone performs their own rule and if they all
do, that will contribute to the well being of the city. Three parts: WORKING CLASS class
of craftsman, (people that do things) guardians (split into two), Idea of justice is that of
harmony, measure or ratio. Greek term=logos Danger to the city is that it is not
organized this way.
Committing injustice is fun, having it done to you is not.
It is worse to suffer, it is self interest that governs this.
o Origin of justice is just done out of sense of gain.
Republic, Book II
Plato / Socrates wants to combat a common view of justice: that “the best is to
do injustice without paying the penalty; the worst is to suffer it without being
able to take revenge.(359A)
That if possible, a person would act unjustly if he knew that he would not be
Ring of Gyges
Glaucon tells the story of the ring of Gyges to demonstrate this point:
It is human to have the “desire to outdo others” for one’s own gain.
“Nature is forced by law into the perversion of treating fairness with respect.” (359c)
Justice is just the interest of the self/benefits/rewards/costs. Only do good, so that you
as a person can feel better due to the fact that you are rewarded.
The origin of Law and Justice (PLATO DOES NOT AGREE)
To do injustice is good, but to suffer injustice is bad. In fact, to suffer unjustice is worse than the benefits of doing injustice.
Thus law begins when people agree to “neither do injustice nor suffer it”(359A)
Thus justice is a mean or a middle ground, between these two extremes.
*What is Plato’s main idea in regards to justice?*Be careful on this question Plato looks at a
common accountive justice that he wants to reject, this view is offensive to him in a lot of
different ways. (we only know what he doesn’t agree upon)
Plato seeks to define justice as measure, ratio or harmony.
Socrates argues that the aim of the rulers should be to establish that “no citizen
should what belongs to another or be deprived of what is his own.”
He was previously established that each member of the city must practice the
occupation for which he (or she) is best suited. In Plato’s city there are
o Those who are producers and who are occupied by crafts (or better skills)
such as shoemaking or farming
o Those who watch over the city(guardians), who are divided between the
auxiliaries or soldiers and the rulers
From these two premises, it follows that justice would each person practicing
Plato seeks to establish that the city and the soul have the same tripartite division
Class in the city Function
Producers Money making, working
Auxiliaires Keeping order
Ruler/philosopher/ king Deliberation, contemplation.
At one point Plato talks about artists and how they have no special belonging(actions of rulers,
Like the city, each part of the soul will only do one thing(436b)
First, Socrates establishes that there are appetites such as hunger, thirst, etc, (437c)
But since each part of the soul can do only one thing, Socrates argues that the soul
cannot just be appetitive, for sometimes despite thirst or hunger, we decide not to eat
or drink (439). Instead, we make a decision about indulging through rational calculation,
which shows that we also have a rational part of the soul (439d)
This leads to a question about the spirited soul (affect/emotion)
The first suggestion is that the spirit is part of the appertite. However, Socrates argues
that spirit reproaches the appetites: “When appetite forces someone contrary to rational calculation, he reproaches himself
and gets angry with that in him that’s doing the forcing (Basically gets mad at the
appetites) so that of the two functions that are fighting a civil war, so to speak, spirit
allies itself with reason.” (440b-c)

Keeping them in order will establish harmony in both the individual and the city
(441d) This is justice. Moderation is to the individual what justice is to the city.
The city is just because each part is doing its own work and so would the
Spirit used correctly is courage(442ff) reason used correctly is wisdom and
moderation balances between the appetite, reason and spirit.
The appetite is dominated by insatiable desire (which, of course, isn’t a virtue at
The spirits virtue, like that of the auxiliary is courage.
The rational part’s virtue, like that of the philosopher king, is wisdom.

Injustice: “must be a kind of civil war between the three parts, a
meddling and doing of another’s work, a rebellion by some part against
the whole soul in order to rule it inappropriately.” (444b)
Parts of the Parts of the Functions/purposes Virtues
Appetite Workers Making money Desire
Spirited Warriors/ Keeping order Courage

King(s) the city to make it just
This is justice in a city, which is moderation to the soul Book IV
Plato gives an argument that the good life is one in which a person cultivates his or her
use of “divine reason.”
This is because divine reason allows for the contemplation of divine things and the order
or harmony of the cosmos.
People were frustrated that Plato thought that men and woman could do the same
thing (divine reason).
He provides another myth/anology stating that we could consider the human being as
having three parts. One is a “multiform” beast having many parts (multiple heads, some
gentle, some vicious), the other a “noble lion” the other a human being.
Note the equivalence with the parts of the soul in Book IV: the appetite=beast,
lion=spirited part, human being= reason
The unjust person
According to Socrates, the unjust person behaves in a way that is like (588e-589a):
First , feeding the savage parts of the multiform besast and the lion
Second, starving the hyman being
Third letting the parts bite, harm and kill each other
The just person
First insures that word and deed maximize the control of the human part(589a)
Second, feeds and domesticates the multi-headed beast, ensuring the growth of the
gentle heads rather than the savage ones (589b)
Third, makes the lion his ally, to care for the other parts(589b)
o Now, this isn’t just an argument for cultivating the good life of “divine reason”.
o Plato also provides a proof for keeping manual workers and other from ruling
o That is: to be ruled is not unjust
First, the best part(reason)of the manual worker is weak, meaning that the worker is
ruled by the multiform beast. (590c)
It is best to be ruled by divine reason.
If a person is not ruled by divine reason, it is best for that person to be ruled by a person
who is ruled by divine reason (590d).
Thus the philosopher king ought to rule.
When reading Aristotle, keep in mind for the 1 Supreme Good. LAST PARA ON PG 23**(spend
some time puzzling out what that proof is about... (end up either on a test or final exam)
When reading, you’ll note that the book is broken up to a regular translation book, it’s
advisable to take notes section by section. Three kinds of lives, different kinds of goods, 2 methods.
Aristotle was a student of Plato, and teacher of Alexander the Great.
Founded a school called the Lyceum, and it was also referred to as the peripatetic
school (refers to walking around).
Wrote dialogues, but now are all currently lost. All we have left are contemporaries
talking about how lovely he is.
1.1 The highest good
The purpose of the Nicomachean Ethics is to discover the supreme good. He is going to
conclude that the supreme Good is happiness in conformity with virtue.
Every art, investigation or practice aims at some Good, and the purpose of the Ethics is
to discover the supreme Good at which all things aim.
That is, the Good is some kind of goal. There are many different pursuits toward some
kind of good; for example, the good and goal of medicine is health.
Goals can also be organized hierarchically, that is some goals subordinate to others, and
those to something else, until they are subordinated to a supreme good.
So, a person does homework to get good grades, because good grades get the person
into grad school, and grad school will allow her to get a Ph.D., and so on.
Aristotle offers another proof for the existence of the Supreme Good. He uses infinite
regress argument to show how the position that there is not a supreme good is absurd
o First he hypothesizes that all aims lead to a supreme good. How?
o Let’s assume that this isn’t true. Then, every action attempts to accomplish a
good and then a further good, without end.
o If this assumption is true, then desire would be “empty and futile”.(23)
o That is absurd; therefore, there must indeed be a supreme good.
1.2 Political Science
Political science is the “ruling” science. Though Aristotle is thinking more of what we
mean by philosophy.
It prescribes what ought to be studied
Honoured capacities, generalship, household management, rhetoric- are subordinate to
It legislates what is to be done and what is to be avoided.
It aims for the good of the city (24). 1.3 Method
This chapter warns against expecting to high of degree of exactitude in political science,
because it discusses generalities.
Aristotle argues that a youth is not a suitable student of politics, as he “lacks experience
of the actions in life with political science argues from and about” (25)
In addition, youths are guided by feelings, while study should be guided by reason:
“if... we are guided by reason in forming our desires and in acting, then this knowledge
will be of great benefit” (25)
1.4 Common beliefs are inadequate
Most people agree that happiness is the highest good, but they do not agree on what
He examines the “three most favoured lives” (26).
The life of gratification: the many view happiness as pleasure and gratification.
The life of honour: cultivated people in politics view happiness as honour. Honour
depends on the fact that other people honour a person of honour, so that it is easy to
take away, when the good should be something that is “hard to take from us” (27)
In addition, virtue at the outset seems problematic. It seems to be something that
somebody can possess while asleep and bad things happen to virtuous people.
There is the life of study or contemplation which is the highest form of life.
Finally, he mentions one more form of life, that one doesn’t choose for itself: the life of
money-making only aims for money because money is useful to acquire other things, so
it isn’t really a supreme good.
1.5 Characteristics of the Good
“Happiness more than anything else seems unconditionally complete, since we
always choose it because of itself, never because of something else” (28).
He notes that happiness being the final and self- sufficient end appears as truism
(self evident truth) However, he still thinks that this must be clarified
The highest good can be identified if we know the function or purpose of a human
being (or what is unique to a human being). (29)
The highest form is going to be the active exercise of the rational faculty.
The mere act of living appears to be shared even by plants, whereas we are looking
for the function peculiar to man; we must therefore set aside the vital activity of
nutrition and growth. Next in the scale will come some form of sentient life; but this too appears to be
shared by horses, oxenm and animals generally.
There remains therefore what may be called the practical life of the rational part of
man. (this part has two divisions, one rational as obedient to principles, the other as
possessing principle and exercising intelligence.”
We can organize goods according to their importance: external goods (which
happiness seems tto require as instrunments) goods of the body, and goods of
the soul. The question is how do we talk of a good of the soul?
There is a big difference whether the Good is conceived as a disposition or an
action. A person can possess a disposition without doing anything with it. So a
virtuous person can be virtuous and be asleep; the the virtue is useless (analogy
with the Olympics). So virtue must be realized in action: activity in conformity
Aristotle: Nicomachean Ethics, Book II
1. Life of honour: honour isn’t, it’s given by others.
2. Life of gratification: pleasure is comparable to animals. Sex and food.
3. Life of money making: money is only a mean. You never reach a goal by just saving
Three lives you wouldn’t want to have, they do not lead to virtue.
What he does want to look for is being able to explain activity in conformity
2.1 Acquiring virtue of Character
For Aristotle, there are two kinds of virtues.
Virtues of thought or intellectual virtues. These are the product of teaching.
Virtues of Character or moral virtues. These are produced through habit (ethos). This chapter aims to establish that moral virtues are produced through habit and are
not natural properties.
First, this argument is supported by the fact that no natural property can be
altered by habit. (Put aside the Aristotelian science for a moment).
Thus because it is nature of a stone to fall, no matter how many times you throw
it in the air, you cannot train it not to fall, just fire cannot be trained to move
Additionally, Aristotle also distinguishes betw
