Albert wrote a great deal, and twenty-one folios remain to us of his writings. He wrote on Dionysius the Areopagite, commentated the _Magister sententiarum_, was specially conversant with the Arabians and the Rabbis, as he was also well acquainted with the works of Aristotle, although he himself understood neither Greek nor Arabic. He likewise wrote on the Physics of Aristotle. There is found in him a remarkable instance of deficient knowledge of the history of Philosophy. He derived the name Epicurean (Opera, T.V. pp. 530, 531) from the fact that they idled away their time [auf der faulen Haut lagen] (ἐπὶ _cutem_) or else from _cura_ because they concerned themselves with many useless things (_supercurantes_). He represents the Stoics as being something like our choir-boys; he says that they were people who made songs (_facientes cantilenas_), and roamed about in porticoes. For, as he here remarks in a very learned way, the first philosophers clothed their philosophy in verses, and then sang them in halls and porches, and hence they are called standers in the porch (_Stoici_). Gassendi relates (_Vita Epicuri_, I. c. 11, p. 51) that Albertus Magnus mentioned as the first Epicureans, Hesiodus, Athalius or Achalius (of whom we know nothing), Cæcina, or, as others call him, Tetinnus, a friend of Cicero, and Isaacus, the Jewish philosopher. How that is arrived at we do not know at all. Of the Stoics Albertus, on the contrary, mentions Speusippus, Plato, Socrates and Pythagoras. These anecdotes give us a picture of the condition of culture in these times. 4. OPPOSITION BETWEEN REALISM AND NOMINALISM. In the fourth place we must mention an important matter, to which much attention was devoted in the Middle Ages, namely that particular philosophic question which formed the subject of controversy between the Realists and the Nominalists, and the discussion of which was continued through very nearly the whole of the Scholastic period. Speaking generally, this controversy is concerned with the metaphysical opposition between the universal and the individual; it occupies the attention of Scholastic philosophy for several centuries, and reflects great credit upon it. A distinction is drawn between the earlier and later Nominalists and Realists, but otherwise their history is very obscure; and we know more of the theological aspect of the subject than of this. a. ROSCELINUS. The beginning of the controversy dates back to the eleventh century, Roscelinus being the earliest Nominalist. The famous Abelard, although he professes to be an opponent of Roscelinus, is himself nothing more or less than a Nominalist. Roscelinus wrote also against the doctrine of the Trinity, and was pronounced guilty of heresy in 1092 at an ecclesiastical council which met at Soissons. His influence was, however, but small.[36]
