Philosophy according to Giles of Rome, De partibus philosophiae essentialibus
Olszewski, Mikołaj (Instytut Filozofii i Socjologii PAN)
Medieval Philosophy and Theology 7 (1998)
Giles of Rome analyzed the question of the division and definition of philosophy three times at the beginning of his philosophical career. He devoted to this subject the prologues of two of his Aristotle commentaries, Commentary on the Physics and Commentary on the Sophistical Refutations. He then devoted a work exclusively to this subject, De partibus philosophiae essentialibus (De partibus [DPPE]). Because of its clear, systematic approach, this text will be the main object of my analysis. I shall, however, discuss material from the two prologues that demonstrates either the evolution of Giles’s thought from the two prologues to De partibus or the changes, corrections, or additions he introduced into the theory of science and philosophy formulated in De partibus.
