Aristotle was a Greek philosopher born in 384 BCE in Stagirus. He studied under Plato at Plato's Academy in Athens for 20 years. Aristotle then started his own school called the Lyceum and taught there until 323 BCE. He wrote extensively on logic, metaphysics, mathematics, biology, ethics, politics and many other subjects. Aristotle is considered one of the most influential ancient thinkers and made major contributions across many fields that are still used today.
3. ARISTOTLES LIFE
Aristotle was born in
384 BCE at Stagirus, a
now extinct Greek
colony and seaport on
the coast of Thrace. His
father Nichomachus
was court physician to
King Amyntas of
Macedonia, and from
this began 粥姻庄壊岳看岳鉛艶s
long association with the
Macedonian Court,
which considerably
influenced his life.
4. ARISTOTLES LIFE
While he was still a boy his father died. At age 17 his
guardian, Proxenus, sent him to Athens, the
intellectual center of the world, to complete his
education. He joined the Academy and studied under
Plato, attending his lectures for a period of twenty
years.

Aristotle: A long walk
to the Golden Mean
Aristotle is a towering
figure in ancient Greek
philosopher, making
contribution to logic,
metaphysics,
mathematics, biology,
botany, ethics, politics,
agriculture, medicine,
dance and theater.
6. He was a student of Plato who in turn studied
under Socrates. He was more empiricallyminded than Plato or Socrates and is famous for
rejecting Platos theory of forms.
7. As a prolific writer
and polymath,
Aristotle radically
transformed most, if
not all, areas of
knowledge he
touched. It is no
wonder that Aquinas
referred to him
simply as The
Philosopher. In his
lifetime, Aristotle
wrote as many as
200 treatises, of
which only 31
survive.

Aquinas
The Philosopher
8. Aristotle was the first to classify areas of human
knowledge into distinct disciplines such as
mathematics, biology, and ethics. Some of these
classifications are still used today.
As the father of the field of logic, he was the first to
develop a formalized system for reasoning. Aristotle
observed that the validity of any argument can be
determined by its structure rather than its content. A
classic example of a valid argument is his syllogism:
All men are mortal; Socrates is a man;
therefore, Socrates is mortal.
9. Aristotle did not take over Platos
Academy, but he started his own
school, the Lyceum.
His teaching method, peripatetics,
involved walking about and talking.
Aristotle became Alexander the
Greats tutor though his philosophy
focused on the polis and Alexander
embraced the vision of a cosmopolis.
10. With Alexanders death, antiMacedonian riots broke out in Athens,
and Aristotle fled lest Athens commit
the same crime twice.
We have over 2,000 pages of writings
attributed to Aristotle including his
great book, Politics.
12. ARISTOTLES WRITINGS
It is reported that 粥姻庄壊岳看岳鉛艶s writings were
held by his student Theophrastus, who
had succeeded Aristotle in leadership of
the Peripatetic School.
The works of Aristotle fall
under three headings:
Collections of
Dialogues and
facts and material
other works of a
Systematic works
from scientific
popular character
treatment
Among his writings of a popular nature the
only one which we possess of any
consequence is the interesting tract On the
Polity of the Athenians.
14. ARISTOTLES LOGIC
Organon
Peripatetics
粥姻庄壊岳看岳鉛艶s writings on the general subject of logic were
grouped by the later Peripatetics under the name
Organon, or instrument. From their perspective, logic
and reasoning was the chief preparatory instrument of
scientific investigation. Aristotle himself, however, uses
the term logic as equivalent to verbal reasoning.
16. ARISTOTLES METAPHYSICS
粥姻庄壊岳看岳鉛艶s editors gave the
name Metaphysics to his
works on first
philosophy, either because
they went beyond or followed
after his physical
investigations. Aristotle
begins by sketching the
history of philosophy. For
Aristotle, philosophy arose
historically after basic
necessities were secured. It
grew out of a feeling of
curiosity and wonder, to
which religious myth gave
18. ARISTOTLES PHILOSOPHY OF NATURE
Aristotle sees the universe as a scale lying
between the two extremes: form without
matter is on one end, and matter without
form is on the other end. The passage of
matter into form must be shown in its various
stages in the world of nature. To do this is the
object of 粥姻庄壊岳看岳鉛艶s physics, or philosophy of
nature. It is important to keep in mind that the
passage from form to matter
within nature is a movement
towards ends or purposes.
Everything in nature has its
end and function, and nothing
is without its purpose. Everywhere
we find evidences of design and rational plan.
20. ARISTOTLES ETHICS
Ethics, as viewed by
Aristotle, is an attempt to
find out our chief end or
highest good: an end which
he maintains is really final.
Though many ends of life are
only means to further
ends, our aspirations and
desires must have some final
object or pursuit. Such a chief
end is universally called
happiness. But people mean
such different things by the
expression that he finds it
necessary to discuss the
22. ARISTOTLES ART AND POETICS
Art is defined by Aristotle as
the realization in external form
of a true idea, and is traced
back to that natural love of
imitation which characterizes
humans, and to the pleasure
which we feel in recognizing
likenesses. Art however is not
limited to mere copying. It
idealizes nature and completes
its deficiencies: it seeks to
grasp the universal type in
the individual phenomenon.
24. ARISTOTLES POLITICS
Aristotle does not regard
politics as a separate
science from ethics, but as
the completion, and almost a
verification of it. The moral
ideal in political
administration is only a
different aspect of that which
also applies to individual
happiness. Humans are by
nature social beings, and
the possession of rational
speech (logos) in itself
leads us to social union.

26. Politics is not the highest thing to be
pursued, but it lays the foundation for
the pursuit of the highest including the
theoretical virtues of wisdom, first
principles, and science.
Political happiness consist of the activities of
all the moral virtues in a full life.
Theoretical happiness is grounded in the
contemplative life.
The philosopher must find a protected place
in the polity to pursue this happiness though
some regimes do not permit the division
between the political and the theoretical.
27. For Aristotle.
Knowledge comes from the senses and can
be true in itself.
Reality consists of matter and form, and
matter is a continuous process of developing
or becoming.
There is First Cause, source of all
change, but is unchangeable itself. This, for
him, is God.
The goal of human life is happiness, to
reach this is moderation or avoidance of
extremes.
Logic would enable man to perceive that the
ideal state is one governed by a rule of
law, a state ruled by the middle class.
28. Happiness
Greeks debated: what is good life, or
what is happiness?
Man on the streets answer: wealth,
fame, beauty.
But what is man? What is his function
(goal/telos), I.e. what is natural for him?
Key premise: man has reason, and his
telos (final end) is to use that reason;
Every
Happiness is an activity of the soul (the
action of
reasoning part of our being) in
man is
accordance with virtue (Nicomachean
geared
Ethics).
towards
happiness. Even contemplation, the highest life for
man, is an activity (Pol. 7.3).
- Aristotle
29. Virtue
Everything has a virtue
Virtue means acting well, in
accordance with ones nature;
Slaves, plants, animals, humans all
have virtues, just as they have goods;
Mans particular virtue to act from
reason, and unless he is a
philosopher, to act for his community.
30. Aristotle.
The founder of logical theory, Aristotle
believed that the greatest human
endeavour is the use of reason in
theoretical activity.
One of his best known ideas was his
conception of "The Golden Mean"
"avoid extremes," the counsel of
moderation in all things.
