Abstract
The first publication of a hitherto lost work on moral philosophy by Galen deserves the attention of scholars interested in the thought of one who was the last great physician of antiquity, who by a peculiar chain of circumstances became the teacher of the Middle Ages in scientific medicine, and who in his own day enjoyed also success as a philosopher. Posterity, it is true, did not regard his philosophical work with the favour it bestowed on his achievements in medicine, and hence a very small number of his philosophical writings has survived to the present day either in the original text or in Arabic translations
