REISCH, Gregor. - Carthusian, b. at Balingen in Württemberg around 1467, d. at Freiburg in Br. on 9 May 1525. He studied at Freiburg, where in 1489 he obtained the title of magister. A friend of Erasmus (v.) and other humanists, he opposed the spread of Lutheranism. He entered the Carthusian Order between 1500 and 1502.
His name is associated with the *Margarita philosophica* (Freiburg in Br. 1503, Basel 1535, 1583), a popularizing work in 12 books, of which the first three are devoted to the trivium, books IV, VII to the quadrivium, books VIII–XI to natural philosophy, and book XII to moral philosophy. The spirit animating the work is Scholastic Aristotelianism tempered by Augustinian and humanist tradition. In Book XI, chap. 23, regarding the many arguments with which some sought to prove the immortality of the soul, we read: «Nos huiuscemodi ratione pro affirmanda animae immortalitate consulte praeterimus; nec ex his quae ab Aristotele in libro De anima, in Metaphysica aut in Ethici scripta cernuntur, evidens demonstratio colligi poterit. Coeterum in De anima libus solum intellectum ab extrinseco advenire astruit; in libro vero De pono et morte (si ipsius est) id clarius expressit». In chap. 30 the Averroist doctrine of the unity of the intellect is refuted.
