‘Abd al-Latif presents two sets of reasons why al-Razi‘s works, full of errors, should not be the object of people’s admiration. In the first place this writer does not possess a specific technical knowledge of the various sciences which he has decided to consider: his use of the medical terminology is inaccurate, for example, in his notes on Avicenna’s Canon. In the second place, since he lacks any didactic method, he simply raises continual sophisms. For these reasons, ‘Abd al-Latif maintains that he should not even try to take on the holy text of the Koran as he did in his commentary on sura 112 or on sura 95 and sura 87 (Gannagé 2011: 227–256; Stern 1962: 57–59).
