Avicenna (Abu ‘Al? al-Husayn ibn ‘Abd All?h ibn
S?n?) was a Muslim philosopher, scientist and physician who was born in Afshana
near Bukhara, now Uzbekistan, in 980, during the Persian Samanid dynasty. His
native language was Persian, but he wrote mostly in Arabic. Early in life he
revealed an unusual intellectual capacity.
At the age of eighteen he had mastered the major
sciences of the time and practiced and taught medicine. He travelled
extensively throughout Islamic East and served various rulers such as Majd
al-Dawla, son of the last emir of the Buyyid dynasty, Shams al- -Dawla, another
Buyyid emir, and ‘Al?’ al-Dawla. He died in 1037 in Hamadhan (now Iran), where
he is buried. Avicenna’s work is vast and covers most of the sciences of his
time, heirs of the ancient Greek sciences, including Aristotle and Galen.
Also worthy of note is the importance of the
Neoplatonic current, which had a special influence on Avicenna’s metaphysics,
through a work by the pseudo-Aristotle, the Theology of Aristotle, which in
fact consisted of excerpts from the Enneads of Plotinus. The Neoplatonic
influence is noted especially in his conception of a first being which is one
and, purely intelligible, who emanates other intellects which in turn give rise
to the celestial spheres.
After the emanation of the celestial spheres,
each animated by its own intellect, the earthly world is generated, where human
beings exist. In that sense, Avicenna was heir to a conception of the universe
that comes from Aristotle and late Antiquity, with a marked distinction between
the perfect heavenly world and the earthly world where there is generation and
corruption. Avicenna also wrote on logic, mathematics, biology, physics,
astronomy and metaphysics, among other sciences.
His great encyclopaedic work al-Shif?’ (The
Cure) is an original compendium of these diverse disciplines. Avicenna
distinguished himself in several areas, namely metaphysics, by elaborating the
concepts of possible, necessary, essence and existence, influenced by Islamic
theology, thereby creating a metaphysical system that would have a major impact
on Western philosophy, particularly on St. Thomas Aquinas, and throughout the
medieval and early modern philosophy, in its reflection on existence and that
which exists. Avicenna also developed a detailed theory on the faculties of the
soul, specifically the human soul, with a highly developed theory of
subjectivity.
In an example provided by Avicenna, the human
soul, as well as human identity, arises entirely separated from the body, in an
explicit affirmation of human self-consciousness, a topic that was resumed
during the modern period, especially since Descartes. One of the most important
works of Avicenna is the Canon of Medicine (al-Q?n?n fi-l-tibb), which Avicenna
began writing around 1013.
This work addresses the human body and general
issues on health and disease, tumours and fractures, pathologies, symptoms and
diagnosis, and various types of treatment. The work continued to be used
regularly in the East and West until the seventeenth century and today still
contains useful information on various medical issues.
