 The most extensive treatment of Aristotelian efficient causation, and the most influential, is given by Ibn Sīnā (987–1037), known to English speakers by his Latinized name, Avicenna. Avicenna treats the efficient cause in numerous works, including Kitāb al-Najāt (Book of Salvation) and Kitāb al-Ishārāt wa-l-tanbīhāt (Book of Remarks and Admonitons), but his most developed accounts of the efficient cause appear in the Physics and Metaphysics of his magnum opus, Kitāb al-Shifāʾ (Book of Healing) (McGinnis and Reisman 2007: 209–211; Inati 2014: Fourth Class; Avicenna PH: I.10–15; Avicenna MH: IV.1–2, VI.1–3).
