The Life of Aristotle
Aristotle (picture)
was born at Stagira, a Greek colony of Thrace, in
the year 384 B.C. His father, a Macedonian named
Nicomachus, was a physician in the court of Amyntas
II, King of Macedonia.
After the death of his parents, Aristotle's
education was directed by Proxenus of Atarneus. In
his eighteenth year, Aristotle went to Athens and
entered the Academy of Plato, remaining there about
twenty years, until the death of the master.
During Plato's last years, Aristotle
collaborated with the master in the revision of his
works. After Plato's death, Aristotle went to
Assus, a city of the Troad, where he lived for
three years. His friendship with Hermias, ruler of
the city, led to his marriage to Pythias, the
ruler's niece and adopted daughter.
About 343 B.C. Aristotle withdrew to Mitylene;
during the same year he was summoned by King Philip
to the court of Macedonia to educate Prince
Alexander, then a youth of thirteen years.
Aristotle remained there for three years, until the
beginning of the famous Asiatic expedition.
Alexander was grateful for the education
received, and supplied his master with the
financial means to form a library and to assemble a
museum of natural history with which Aristotle
enriched his school. Aristotle had returned to
Athens in the year 335. B.C., and there had opened
a school in the gardens dedicated to Apollo
Lyceios.
The school was hence called the Lyceum, and also
the Peripatetic School, probably from Aristotle's
custom of teacher, discussing and conversing with
his pupils while walking along the shady lanes of
the garden. He taught in the Lyceum for twelve or
thirteen years, and composed the greater part of
his books during that time.
In 323 B.C., upon the death of Alexander, there
was reawakened in Athens conflict between the
followers of the Macedonian party and the enemies
of Alexander. The national reactionaries were led
by the great Greek orator Demosthenes.
Aristotle, as a Macedonian sympathizer, was
accused of impiety, which meant that he would be
called to judgment to hear the sentence of death
passed upon himself. He anticipated the
condemnation and voluntarily retired to Chalcis,
where he possessed a villa inherited from his
mother.
It is said that while departing for exile he
uttered these words, referring to the condemnation
of Socrates: "I do not wish that Athens should sin
twice against philosophy."
His school, including the library and the museum
of natural history, went to his disciple
Theophrastus. Aristotle died in 322. B.C., at
Chalcis in Euboea.

The Works of Aristotle
Aristotle, whom Plato is said to have surnamed
"The Intellect," certainly had the loftiest mind
ever known in Greece, and perhaps in the entire
human race. He is the type of true philosopher who,
not allowing himself to be distracted by practical
and political motives, lives entirely engrossed in
his speculations.
The books edited by him and comprising all the
knowledge of his day number about a thousand. Of
these works, some were destined for the public, and
some for Aristotle's school. The greater part of
his works has been lost, but some important parts
have been preserved, that is, those works destined
for his school and representing the philosophic
thought of this greatest of philosophers.
The complete edition was published for the first
time by Andronicus of Rhodes about the middle of
the last century before Christ. Following the
classification of Andronicus of Rhodes and passing
over the scientific books which have no direct
connection with philosophy, the works of Aristotle
comprise the following groups:
1. Logic
The works on logic were called the
Organon, that is, an instrument of learning.
The Organon includes the following:
- The Categories
- On Interpretation
- Prior Analytics (on the syllogism)
- Posterior Analytics (on Demonstration)
- Topics
- Sophistic Refutations
2. Physics
The works on physics comprise the body of
doctrine which is today embraced by cosmology and
anthropology:
- Physics (in eight books)
- Concerning the Heavens (in four books)
- Concerning Birth and Corruption (in two
books)
- Meteorology (in four books)
- On the Soul (in three books)
3. Metaphysics
Aristotle's Metaphysics is usually divided into
fourteen books. These are a compilation made after
the death of Aristotle and are based on manuscript
notes referring to general metaphysics and
theology. The name "metaphysics" is due to the
position of these works in the collection edited by
Andronicus; they appeared "after the works on
physics."
4. Ethics and Politics
- Nichomachean Ethics (in ten books, dedicated
to Aristotle's con, Nicomachus, named after
Aristotle's father)
- Eudemian Ethics
- The Great Ethics
- Politics (in eight books, unfinished)
5. Rhetoric and Poetry
- Rhetoric (in three books)
- Poetics (in two books)
These books, of course, are only a part of the
works of Aristotle.

Introduction to Aristotle's Doctrine
Plato had split reality into two worlds:
- The World of Ideas (eternal,
immutable, unchangeable, like the "being" of
Parmenides, but fashioned according to the
Socratic concept); and
- The World of Sensible Things
(mutable, changeable, like the "being" of
Heraclitus).
Plato had been induced to divide the world of
reality because he believed that only by such a
separation could he give metaphysical foundation to
the concept of Socrates without denying Heraclitus'
doctrine of "fluent reality" -- the object of
immediate experience.
Aristotle found that the weakest point
of his master's doctrine lies in this separation of
the world of Ideas from the world of sensible
things. "It would seem impossible for the substance
and that which is the substance to exist in
separation." (1)
How can Ideas be causes of the motion and change
in the visible world if Ideas are separate from
things? Plato had held that Ideas are patterns or
models of things. Aristotle holds that to say this
"is to use empty phrases and poetical metaphors;
for what is it that fashions things on the model of
Ideas?" (2) Since Ideas are separated from reality
and are themselves immutable, unchangeable, they
cannot be the cause of the motion and of change in
sensible things.
Nor does the teaching of separate Ideas
help toward the knowledge of other things, for
Ideas are not the substance of particulars, but are
separated from them. Hence, how would it be
possible to have any knowledge of sensible
substances if what constitutes these substances
(Ideas) is really separated from them?
The cause of motion and change, according to
Aristotle, must be sought in the thing itself as an
immanent element of the reality. Only when an
understanding of the factor or factors of motion is
had can we have a true knowledge of things; for
these factors of motion are the key to
understanding the concept of Socrates.
Thus any investigation must start from things
which begin to be, develop, and then pass away.
Although sensible reality is in continuous
"becoming," the "factors" of this becoming are
unchangeable, immutable. Only when the causes of
motion are grasped as intrinsic factors of motion
itself will we have a true understanding of
reality, i.e., knowledge by causes.
In other words, the intelligibility of sensible
things must be sought in the things themselves, and
not in a separate world of Ideas, as Plato
believed.
