Avicenna (Ibn Sina) (picture)
was a Persian philosopher who spent his life as a
physician and scholar-in-residence at many Islamic
courts. He died while in service in Isfahan. Nearly
a thousand years have passed and the name of
Avicenna is still revered in the East. One of the
wisest of physicians, he is referred to in the West
as the Galen of the Moslem world.
The name Avicenna is the Latinized form of the
Hebrew, Aven Sina; or the Arabic, Abu Ali al-Husain
ibn Abdullah ibn Sina. While still a youth in his
teens, Avicenna was called upon to cure the Sultan
of Bokhara. The potentate, in gratitude, opened his
library to the young man. This good fortune enable
Avicenna (who had memorized the Koran by the age of
ten) to write the Canon, the basis of his
medical fame, before he had attained his legal
majority.
Many of his writings were translated in the
West. Avicenna's works are of a compendious nature,
the most notable being a philosophical
encyclopedia. As did other Muslim scholars of the
Greek school, he attempted to reconcile philosophy
and Islam. For Avicenna, philosophy was the true
path to understanding. His summaries of Aristotle
reveal a neo-platonic outlook, especially in his
emphasis on the dualism of mind and matter. He saw
matter as passive and creation as the act of
instilling existence into this passive substance;
only in God are being and existence one.
Avicenna also wrote numerous works on medicine.
His best known is the Canon of Medicine,
based primarily on Greco-Roman medical tracts. An
extraordinarily popular work, it was translated
into Latin and served as a foundation of medical
learning in European universities for
centuries.
In addition to his medical accomplishments, he
studied logic, metaphysics, mathematics, and
physics. He studied Aristotelian and the
neo-Platonic philosophy of al-Farabi. As a result
of this, Avicenna wrote voluminously on Aristotle.
He said that cause and effect are simultaneous and
therefore God and the world are co-eternal; that
God created intelligence or the soul, and these
emanate from the heavens and reach the earth in
huge chains; that intelligence is sustained by God,
and though that is innately eternal, its multiple
extensions are not dependent on Him, for He is not
concerned with matter.
Avicenna was probably a pantheist. His work
Philosophia Orientalis, in which his
position was apparently clarified, is lost. His
mysticism is said to have been derived from
Mazdaism. For a time he occupied the office of
Vizier at Hamadan.

Al-Ghazali
- (1059 - 1111)
Main Ideas:
- The world was created in time and has a
beginning.
- Rationalistic philosophy fails to bring
about certainty.
- There are twenty fallacies committed by the
Peripatetic philosophers.
- A mystical vision of truth is the only way
towards the attainment of certainty.
Important Works:
- Intentions of the Philosophers
- The Deliverer from Error
- Incoherence of the Philosophers
- The Just Mean in Belief
- Revival of Religious Sciences
- The Elixir of Happiness
Abu Hamid Muhammad al-Ghazali, born in the
northeastern part of the Persian empire, was a
philosopher, theologian, mystic, and apologist, and
one of the most revered personalities in the Muslim
world. The greatest teachers of Islam have bestowed
upon him inumerable encomiums, among them, "the
guide to the True Faith," "the embodiment of
religious thought," "the living reaffirmation of
Islam."
In his spiritual autobiography The Deliverer
from Error, Ghazali describes the great crisis
that forced him in 1095 to abandon his brilliant
professional career in Baghdad and to search for an
inner, direct knowledge of the reality of God. He
adopted the life of a wandering ascetic and mystic,
visited Damascus, Jerusalem, and Mecca, and lived
with some disciples in his birthplace, Tus (in
present-day Iran), before he was persuaded to
return in 1106 to his teaching career. He retired
to Tus in 1110. Of his more than 50 books, the
The Incoherence of the Philosophers and
The Revival of the Religious Sciences are
particularly important.
Ghazali, never a bigoted orthodox, both
advocated and practiced tolerance. He often advised
his co-religionists to take the pious Jew as their
model in religious reverence. In fact, Jewish
philosophers of the Middle Ages soon became aware
that Ghazali's principles and teachings were
closely akin to those of Judaism, a fact that has
often been confirmed by modern Christian
scholars.
Ghazali was deeply influenced by Sufism despite
his faithful study of the Koran. His doctrine of
emanation was derived from neo-Platonic writings.
He classified those who denied this doctrine as
children, for both confuse marionettes or wooden
idols with reality. His criticisms of causality
pre-dated David Hume's parallel theories by several
centuries, and he exerted great influence over
William of Ockham and other Christian philosophers.
He compared the pursuit of knowledge to the process
involved in digging a well: both involved probing;
the desired object in both cases was necessary to
life.

Ibn
Tufail - (c. 1105 - 1185)
The author of "Robinson Crusoe" certainly must
have read the English version of Ibn Tufail's book
Hai Ebn Yokdhan (Alive, Son of Awaken), the
imaginary and allegorical story of a man who,
living alone on an island, without any intercourse
with human beings, discovered truth and conquered
nature by reasonable thinking. This book became
favorite reading in Europe. It was translated into
French, Spanish, German and Dutch, and into English
in 1674 and 1708. Its English title is The
Improvement of Human Reason.
The full name of its author is Abu Bekr Mohammed
ben Abd'el Malik ben Mohammed ben Mohammed ben
Tu-fail el-Quaici. His contemporaries also called
him El Andaloci, which, at that time, meant
Spaniard, or the man of Cordova, or the man of
Seville. He was a physician in Granada who then
became secretary to the governor and finally vizier
of Sultan Abu Yakub Yusuf, who ruled over Islamic
Spain and Morocco.
Ibn Tufail distinguished himself in medicine,
poetry and astronomy. He criticized the Ptolemaic
system as did other Arabic and Jewish thinkers of
that period. He was highly respected as a scholar
whose wisdom attracted men of all countries. The
chronicles of his time also praise him as a
Maecenas. Ibn Tufail especially protected Averroes
and recommended him to his ruler as his successor
when, in 1182, he retired from office.
According to contemporary reports, Averroes was
inspired to his commentaries on Aristotle by a
conversation with Ibn Tufail and the Sultan, who
complained that Aristotle was too obscure to
him.

Avenpace
(Ibn Badjdja) - (c. 11th century -
1138)
Avenpace was a high dignitary in Islamic Spain
for twenty years when he was poisoned by his
enemies who decried him as an atheist and scorner
of the Koran.
He was a reputed musician and well acquainted
with the natural sciences, mathematics and
astronomy. Avenpace wrote commentaries on sever
works of Aristotle, whom he interpreted in
accordance with neo-Platonism, and treatises among
which The Hermit's Guide was most famous. It
was used by Averroes and the Jewish author Moses of
Narbonne, as well as by Albertus Magnus and
Aquinas.
He distinguished between "animal" and "human"
activities, regarded the human intellect as the
emanation of the Agent Intellect, the supreme
Being, and described their mystical union.
