Avicenna
A physician trained to diagnose bodies as if they were puzzles of motion became the philosopher who gave one of the boldest arguments ever made for self-awareness: the soul, stripped of all sensation and circumstance, would still know that it is. Avicenna’s “floating man” turned introspection into a metaphysical clue.

Timeline
Birth of Avicenna near Bukhara
**980 AD** — Avicenna was born in 980 into the Persianate Islamic world, where translation, medicine, theology, and courtly learning were deeply intertwined. His later philosophy would grow out of this environment of cosmopolitan scholarship and political instability.
Early study in grammar, logic, and medicine
**990 AD** — As a youth, Avicenna entered the full range of the learned sciences, from religious jurisprudence to logic and medicine. The tradition of his precocious education became part of his intellectual legend, but it also marks how quickly he moved into the central debates of his age.
Access to the Samanid library
**996 AD** — Avicenna’s account of gaining access to the royal library is one of the formative moments in his intellectual biography. Whether read literally or as a stylized memory, it symbolizes his entry into the Arabic philosophical and scientific inheritance.
Begins composing major philosophical works
**1005** — In his early adulthood, Avicenna began producing the works that would define his philosophical reputation, including the encyclopedic project that later became the Shifa' (The Healing). This period marks the consolidation of his logic, metaphysics, and psychology into a single system.
Floating man argument articulated in the Kitab al-Shifa'
**1020** — Avicenna’s famous thought experiment appears in his discussions of the soul, where he argues that a person suspended in isolation would still know that he exists. The argument became one of the most influential philosophical treatments of self-awareness in the medieval world.
Al-Isharat wa'l-Tanbihat refines his mature philosophy
**1027** — In The Book of Directives and Remarks, Avicenna presented a compressed and more difficult version of his mature thought. The work became central for later interpreters because it reveals how he understood the relation between demonstration, intuition, and metaphysical insight.
Debates with theologians and philosophers intensify
**1030** — Avicennian philosophy became a major target for theologians concerned about causation, divine freedom, and the nature of the soul. These disputes helped determine the later shape of Islamic intellectual history and prepared the ground for al-Ghazali’s critique.
Death of Avicenna in Hamadan
**1037-06** — Avicenna died in 1037 after a life of extraordinary productivity and mobility. His death did not end his influence; rather, it marked the beginning of a long philosophical afterlife across Islamic and Latin traditions.
Latin translation movement spreads Avicennian thought
**1120** — In the twelfth century, Avicenna’s philosophical and medical works began entering Latin Europe through translation. These texts supplied medieval scholastics with new formulations of essence, existence, soul, and causation.
Birth of al-Ghazali, later critic of Avicenna
**1058** — Al-Ghazali’s later critique of the philosophers would become one of the most important responses to Avicennian metaphysics. His attack on causal necessity radically altered the philosophical landscape in which Avicenna was read.
Avicenna’s metaphysics absorbed into scholastic debates
**1270** — By the late thirteenth century, Avicenna’s distinction between essence and existence had become a live issue in Latin scholastic philosophy. Even thinkers who opposed him often argued in terms he helped define.
Modern scholarly revival of Avicenna studies
**1900** — Twentieth-century historians of philosophy and Arabic studies renewed close attention to Avicenna’s texts, correcting older caricatures and recovering the sophistication of his metaphysics and psychology. This revival set the stage for contemporary interest in the floating man and self-awareness.
