In ‘Abd al-Latif’s opinion, the medicine of his age must rediscover and apply Greek medicine with its principles, descriptions of diseases, and therapies. Greek theoretical medicine is concerned with universals and is founded on the ground of universal principles which are valid everywhere. In this respect, according to him, Greek medicine is far superior to his contemporaries’ practice and must be learned by the physicians of his age according to the principle of accumulation of knowledge which also guides ‘Abd al-Latif’s philosophical project.
