Proclus
Proclus (412–485 CE), the great Neoplatonist philosopher of late antiquity, sought to harmonize Plato’s thought with theology, mathematics, and metaphysics. As head of the Athenian Academy, he systematized Platonic philosophy into a grand hierarchy of reality: the ineffable One, divine Intellect, and World Soul. He emphasized theurgy, ritual practices meant to unite the soul with the divine, blending philosophy with spirituality. Proclus wrote extensive commentaries on Plato, influencing Christian, Islamic, and Renaissance thinkers. His vision of a cosmos infused with order and divinity made him a bridge between classical philosophy and medieval theology, shaping centuries of metaphysical thought.
This, therefore, is mathematics: she reminds you of the invisible form of the soul; she gives life to her own discoveries; she awakens the mind and purifies the intellect; she brings light to our intrinsic ideas; she abolishes oblivion and ignorance which are ours by birth.
