Introduction to the Philosophy and Writings of Plato

"Philosophy," says Hierocles, "is the purification and perfection of human life. It is the purification, indeed, from material irrationality, and the mortal body; but the perfection, in consequence of being the resumption of our proper felicity, and a reascent to the divine likeness. To effect these two is the province of Virtue and Truth; the former exterminating the immoderation of the passions; and the latter introducing the divine form to those who are naturally adapted to its reception." Of philosophy thus defined, which may be compared to a luminous pyramid, terminating in Deity, and having for its basis the rational soul of man and its spontaneous unperverted conceptions,?of this philosophy, August, magnificent, and divine, Plato may be justly called the primary leader and hierophant, through whom, like the mystic light in the inmost recesses of some sacred temple, it first shone forth with occult and venerable splendour. It may indeed be truly said of the whole of this philosophy, that it is the greatest good which man can participate: for if it purifies us from the defilements of the passions and assimilates us to Divinity, it confers on us the proper felicity of our nature. Hence it is easy to collect its pre-eminence to all other philosophies; to show that where they oppose it, they are erroneous; that so far as they contain any thing scientific they are allied to it; and that at best they are but rivulets derived from this vast ocean of truth.
