====== Ibn Sina ======

Ibn Sina (c. 980 - 1037), known in Latin as Avicenna, was a Persian polymath whose work in philosophy and medicine became a foundational reference point for both the Islamic and Latin Christian intellectual traditions. He is best known for the //Book of Healing// (//Kitab al-Shifa//), a wide-ranging philosophical encyclopedia, and the //Canon of Medicine// (//al-Qanun fi al-Tibb//), a medical textbook that remained in use in European universities into the early modern period. His philosophical project synthesized Aristotelian logic and natural philosophy with Neoplatonic emanationist metaphysics, producing a system distinct enough from [[aristotle|Aristotle]] that later thinkers, including [[qutb-al-din-al-shirazi|Qutb al-Din al-Shirazi]], engaged with it as a school of thought in its own right rather than mere commentary. The proper characterization of Ibn Sina's relationship to Aristotle - faithful interpreter, creative synthesizer, or independent system-builder - is itself contested among historians of philosophy; see [[ibn-sina-aristotle-relationship-viewpoint]].

===== Current State of Knowledge =====

Scholarship on Ibn Sina spans several disciplines: history of philosophy, history of medicine, and history of science, each with its own emphases. Historians of philosophy generally treat his metaphysics - particularly his distinction between essence and existence, and his arguments for a Necessary Existent - as a major and original contribution to medieval thought, influential on both later Islamic philosophers and on Latin scholastics such as Thomas Aquinas and Duns Scotus. Historians of medicine generally treat the //Canon// as a systematizing achievement that organized and extended earlier Greek and Islamic medical knowledge rather than as a source of novel clinical discoveries, though this characterization is debated in particular cases (e.g., his accounts of contagion and quarantine). The extent to which Ibn Sina should be read as continuous with or departing from Aristotelian philosophy remains debated; see [[ibn-sina-history]] for the historical development of his thought and its reception. A further line of disagreement concerns Ibn Sina's relationship to religious orthodoxy: whether his philosophical system is compatible with mainstream Islamic theology or represents a departure from it, a question sharpened by [[al-ghazali|al-Ghazali]]'s later critique. See [[ibn-sina-philosophy-religion-compatibility-debate]].

===== Viewpoints =====

  * **Continuity viewpoint**: Holds that Ibn Sina's system is best understood as a development and systematization of Aristotelian philosophy, filling gaps and resolving tensions in the Aristotelian corpus rather than departing from it. See [[ibn-sina-aristotelian-continuity-viewpoint]].
  * **Independent system viewpoint**: Holds that Ibn Sina's incorporation of Neoplatonic emanation, his modal metaphysics of necessity and contingency, and his theory of the active intellect constitute a distinct philosophical system that uses Aristotelian vocabulary toward different ends. See [[ibn-sina-independent-system-viewpoint]].
  * **Theological-critical viewpoint**: Associated with al-Ghazali and later traditionalist critics, holds that key elements of Ibn Sina's metaphysics (e.g., the eternity of the world, denial of bodily resurrection in a literal sense) are incompatible with Islamic orthodoxy. See [[ibn-sina-theological-critical-viewpoint]].
  * **Medical-empiricist viewpoint**: Emphasizes the //Canon of Medicine// as a work of clinical and observational value distinct from, and to be assessed separately from, Ibn Sina's metaphysical commitments. See [[ibn-sina-medical-empiricist-viewpoint]].

===== Controversies =====

  * Dispute over the authenticity and interpretation of Ibn Sina's "Floating Man" (or "Flying Man") thought experiment and its bearing on mind-body dualism. See [[ibn-sina-floating-man-controversy]].
  * The historical controversy between Ibn Sina's philosophical theology and al-Ghazali's critique in //The Incoherence of the Philosophers//, and Ibn Rushd's subsequent defense. See [[ibn-sina-al-ghazali-incoherence-controversy]].
