Although Abu Hamid Muhammad al-Ghazali lived a relatively short life (1058-1111), he established himself as one of the most important thinkers in the history of Islam. The Incoherence of the Philosophers, written after more than a decade of travel and ascetic contemplation, contends that while such Muslim philosophers as Avicenna boasted of unassailable arguments on matters of theology and metaphysics, they could not deliver on their claims; moreover, many of their assertions represented disguised heresy and unbelief. Despite its attempted refutation by the twelfth-century philosopher Ibn Rushd, al-Ghazali's work remains widely read and influential.

Sadr al-Din Muhammad Shirazi (1572-1640), more commonly called Mulla Sadra was one of the grand scholars of later-period Islamic philosophy and has grown to become one of the best-known Muslim philosophers. "Iksir al-Arifin" or "Elixir of the Gnostics", is unique among Sadra's writings in that it reworks and amplifies an earlier Persian work, the "Jawidan-nama" ("Book of the Everlasting") by Afdal al-Din Kashani, or Baba Afdal. The underlying theme of Sadra's amplification is emblematic of Muslim philosophy: the importance of self-knowledge is an individual's journey of "Origin and Return", the soul's origins with God and its eventual return to Him. Everything, Sadra says, is on such a path, gradually disengaging from the material world and returning to a transdencent essence - all leading to a final fruition in which everything in the universe returns to God and finds permanent happiness. Philosophy, Sadra argues, is the most direct means to self-knowledge - and thus the best tool for navigating this journey.

Shihab al-Din al-Suhrawardi was born around 1154, probably in Northwestern Iran. Spurred by a dream in which Aristotle appeared to him, he rejected the Avicennan Peripatetic philosophy of his youth and undertook the task of reviving the philosophical tradition of the "Ancients." His philosophy grants an epistemological role to immediate and atemporal intuition. It is explicitly anti-Peripatetic and is identified with the pre-Aristotelian sages, particularly Plato.

Averroës (Ibn Rushd, 1126-1198) emerged from an eminent family in Muslim Spain to become the first and last great Aristotelian of the classical Islamic world; his meticulous commentaries influenced Christian thinkers and earned him favorable mention (and a relatively pleasant fate) in Dante's Divina Commedia. The Book of the Decisive Treatise was and remains one his most important works and one of history's best defenses of the legitimate role of reason in a community of faith. The text presents itself as a plea before a tribunal in which the divinely revealed Law of Islam is the sole authority; Averroës, critical of the anti-philosophical tone of the Islamic establishment, argues that the Law not only permits but also mandates the study of philosophy and syllogistic or logical reasoning, defending earlier Muslim philosophers and dismissing criticisms of them as more harmful to the Islamic community than the philosophers' own views had been. As he details the three fundamental methods the Law uses to aid people of varied capacities and temperaments, Averroës reveals a carefully formed and remarkably argued conception of the boundaries and uses of faith and reason.

"Avicenna's Physics" is the very first volume that he wrote when he began his monumental encyclopedia of science and philosophy, "The Healing". Avicenna's reasons for beginning with "Physics" are numerous: it offers up the principles needed to understand such special natural sciences as psychology; it sets up many of the problems that take center stage in his Metaphysics; and it provides concrete examples of many of the abstract analytical tools that he would develop later in "Logic". While "Avicenna's Physics" roughly follows the thought of "Aristotle's Physics", with its emphasis on natural causes, the nature of motion, and the conditions necessary for motion, the work is hardly derivative. It represents arguably the most brilliant mind of late antiquity grappling with and rethinking the entire tradition of natural philosophy inherited from the Greeks as well as the physical thought of Muslim speculative theologians. As such, "Physics" is essential reading for anyone interested in understanding Avicenna's complete philosophical system, the history of science, or the history of ideas.
