 We had read that the philosopher of Nature is concerned with Prime Matter, but “since matter belongs to the genus of relation”, i.e., it depends on its relation to form (LC 58K TC26; Phys. II.2, 194b9), its study also involves the study of form. Averroes mentions that matter exists on account of form, propter formam, and that the philosopher of Nature investigates both. He investigates form per se, and matter because of form (LC 58L), but the issue of how far his research can go arises. The philosopher of Nature searches for form and  quiddity[3]  and goes as far as to the last, or highest form on the account of which matter exists, and this is man’s form, forma hominis (LC 59A TC26). Averroes is very assertive and once again he disagrees with Avicenna when he claims that only the metaphysician deals with these forms. For Averroes, the metaphysician studies the abstract forms, i.e., existing without matter, while the philosopher of Nature, the material forms but also the human form which is an intermediate between them and the purely abstract forms (LC 59D).
