‘Abd al-Latif proceeds to criticize Avicenna’s theory of the syllogism and in particular his admission of the hypothetical syllogisms. Finally, ‘Abd al-Latif makes a series of further criticisms of Avicenna without, however, going into each of them in detail. Avicenna has enlarged the book of the Poetics with an amount of material which actually derives from the Rhetoric. Since Avicenna’s Kitab al-Shifa’, despite its numerous errors, has become the philosophical encyclopedia of reference among ‘Abd al-Latif’s contemporaries, he believes that Avicenna is the indirect cause of the vast spread of philosophical errors, such as the confusing, for example, the object proper to the Physics, that is, nature, with that of the Metaphysics.
