et corruptione, de sensu, the Historia animalium, the spurious Meteorologia, and the de anima. On mental and moral science they had the Metaphysics, the Nicomachæan Ethics and the Magna Moralia. Strangely enough the Politics was not included in the Aristotelian canon, its place being taken by Plato's Laws or Republic. Besides these the Arabic students accepted as Aristotelian a Mineralogy, of which we have no knowledge, and a Mechanics.
Of these the logical Organon always remained the basis of a humane education, side by side with the indigenous study of grammar, and this essentially logical basis of education seems to have been influenced by the example of the existing system developed amongst the Syrians, although it must be remembered a similar system was developed quite independently in Latin scholasticism prior to the earliest contact with the Arabic writers. The Aristotelian logic has always remained an orthodox and generally accepted science. The philosophical and theological controversies and the developments produced by the Arabic philosophers centred mainly in questions of metaphysics and psychology, and so were particularly concerned with the 12th book of Metaphysics and the treatise de anima, more especially the 3rd book. As we have already noted the psychology of Aristotle was interpreted in the light of Alexander of Aphrodisias' commentary, and thus received a theistic and supernatural colouring which receives its fuller development in neo-Platonic teaching.
