How a Short Treatise Unlocked Aristotle for Avicenna

Avicenna, writing generations after Al-Farabi's death, left behind an unusually candid account of his own struggle with Aristotle's Metaphysics, reporting that he had read the text forty times and memorized it without understanding its purpose, until he came across a short treatise by Al-Farabi explaining the aims of the Metaphysics that finally made the work make sense to him. Avicenna describes buying the treatise cheaply from a bookseller who assumed it worthless, and reports rushing home to read it and finding his difficulty immediately resolved. The anecdote, preserved in Avicenna's own autobiographical notes, is one of the clearest direct lines of transmission between the two philosophers who between them did more than perhaps any other pair of thinkers to establish Aristotelian metaphysics as a working part of Islamic philosophy, Al-Farabi supplying the logical and metaphysical groundwork that Avicenna then built into his own far larger philosophical system. The story also illustrates how philosophical texts moved and were valued in the book markets of Baghdad and the wider Islamic world, sometimes changing hands for a few coins between booksellers who had no way of knowing which pamphlet would matter most. It remains a rare case in the history of philosophy where one major thinker's own testimony credits a specific short work by name for making a canonical but notoriously difficult text finally legible to him.
