Islamic philosophy (Arabic: al-falsafa al-islamiyya, sometimes rendered falsafa) refers to philosophical activity conducted within, or in dialogue with, the intellectual world shaped by Islamic civilization, drawing on Greek, Persian, and Indian sources alongside the Qur'an and Islamic theology. The scope of the term is itself contested - some scholars restrict it to thinkers working primarily in the Hellenistic-influenced falsafa tradition, while others apply it more broadly to include Islamic theology (kalam), mysticism (Sufism), and jurisprudential reasoning; see islamic-philosophy-scope-viewpoint and islamic-philosophy-falsafa-vs-kalam-debate.

Contemporary scholarship increasingly treats Islamic philosophy as a continuous tradition extending from the early translation movement of the 8th and 9th centuries through to present-day work by scholars such as Seyyed Hossein Nasr, rather than a tradition that terminated after Averroes in the 12th century ¹⁾. This “death thesis” - the claim that Islamic philosophy ended or decayed after the classical period - has been challenged by substantial scholarship on post-classical figures in Iran, Ottoman lands, and South Asia ²⁾, though it continues to be defended by some scholars and reflected in some Western philosophical curricula. See islamic-philosophy-history and islamic-philosophy-decline-debate.

Major figures conventionally treated under this heading include Avicenna (Ibn Sina), whose systematic metaphysics shaped both Islamic and Latin scholastic philosophy; Al-Ghazali, whose critique of the philosophers in The Incoherence of the Philosophers is variously read as a rejection of falsafa or as itself a work of sophisticated philosophical theology ³⁾; and Averroes (Ibn Rushd), known for his commentaries on Aristotle and his defense of philosophy's compatibility with religious law. Modern figures such as Seyyed Hossein Nasr have extended the tradition into engagement with comparative religion, traditionalism, and critiques of modernity.

• Falsafa as authentic philosophy - holds that the Peripatetic and Neoplatonic tradition represented by figures like Avicenna and Averroes constitutes genuine philosophical inquiry, continuous with the Greek tradition. See islamic-philosophy-falsafa-authenticity-viewpoint.
• Theological priority - holds that kalam and revelation-centered reasoning, as practiced by thinkers in the line of Al-Ghazali, represent the more authentically “Islamic” mode of inquiry, with falsafa treated as a foreign import requiring scrutiny. See islamic-philosophy-theological-priority-viewpoint.
• Perennialist/traditionalist viewpoint - associated with Seyyed Hossein Nasr and the Traditionalist School, holds that Islamic philosophy expresses a sacred, perennial wisdom shared across traditional civilizations, and is critical of secular modernity's effect on philosophical inquiry. See islamic-philosophy-perennialist-viewpoint.
• Decline narrative viewpoint - associated with certain 19th- and 20th-century Orientalist and some Muslim modernist scholarship, holds that independent philosophical inquiry in the Islamic world diminished after the classical period, often attributing this to the influence of Al-Ghazali's critique or to broader institutional changes. See islamic-philosophy-decline-narrative-viewpoint.
• Continuity viewpoint - held by many contemporary historians of philosophy, holds that philosophical activity continued robustly in later centuries, particularly in Safavid Iran and the Indo-Islamic world, and that the decline narrative reflects gaps in Western scholarship rather than gaps in the tradition itself. See islamic-philosophy-continuity-viewpoint.

• The reception and interpretation of Al-Ghazali's Incoherence of the Philosophers and Averroes's response, The Incoherence of the Incoherence, remains a documented point of scholarly dispute over its implications for the status of philosophy in Islamic intellectual life.
