The Bactra Review Avram
The quotation is actually a paraphrase provided by Barry S. Kogan on p. 155 of
his Averroes and the Metaphysics of Causation (Albany, NY:
SUNY Press, 1985). I have not been able to lay hands on a copy of
al-Ghazali's Incoherence to provide a verbatim statement, which
I recall as being verbally quite striking.
