ABSTRACT
This essay is an exploration of a problem that arose quite unexpectedly in the course of collecting passages bearing on Theophrastus’ views on the intellect. It has led me into important areas about which I know very little, and I hope to give those who may know even less than I do an idea of the issues involved. The central problem is whether there is evidence for Theophrastus' views in Arabic and medieval Latin sources which is not derived from Greek sources known to us. If there is such evidence, we can also ask how it reached those authors who survived, and to what extent their accounts are a fair record of what Theophrastus actually said.
