Abstract

This article sheds new light on the sixth/twelfth-century anti-Avicennan current, which took its cue primarily from al-Ghazālī’s Incoherence of the Philosophers . A key representative of this current, Ibn Ghaylān al-Balkhī , veers away from the usual points of conflict in metaphysics and natural philosophy, directing his attention instead to descriptions of the properties of simple drugs in Avicenna's Canon of Medicine and Heart Remedies and Ismāʿīl al-Jurjānī's medical encyclopaedia The Khwārazmshāhī Treasure . In a dedicated text, he highlights various inconsistencies in these sources, with a view to demonstrating that Avicenna's works are unreliable and exposing a culture of uncritical imitation among contemporary Avicennists. The article includes an edition and translation of the text
