"The dialectical method developed by Proclus triumphed in modern philosophy in the form of Hegelian dialectics. Proclus considers the world of thought in reality to be entirely dominated and interpretable by the process of the One as outlined in metaphysics; therefore, for him, metaphysics is logic. The fundamental categories and ideas are identified, and everything is continually reduced to a single thought, which is that of unity. (Le scuole neoplatoniche, “'The Neoplatonic Schools”', XXXVII, p. 222)"
