Guenon’s objection is not to philosophy per se, but to a philosophy denuded of esoteric content. At the heart of Plato’s philosophy is the Form of the Good – God, the Source. The Form of the Good is clearly the object of mystical revelation and it gives all reality a divine quality. Thus, reality is being generated by God and it shares in God’s divine nature. Wisdom must be grounded in reality. Rational philosophical reflection must be centered around the real. If the divine is absented from philosophical speculation, then a vacuum is created. This vacuum can only be filled with malignant creations of the human imagination.

Plato’s Allegory of the Cave is a useful starting point for all attempts to understand Platonic philosophy. Everything Plato writes presupposes such a vision of reality. Plato has a place for rationality, but he at no point tries to deduce morality from merely rational considerations.

Plato saw that ethics without an appreciation of the divine origins of life is meaningless and a hopeless task. God is the alpha and the omega; the origin and destination. Rationalism, on the other hand, loses its way.

Very interesting article emphasising the experiential and mystical foundation of Platonism and the problem of modern rationalism divorced from the supra-rational.

I will be discussing this in a show on the allegory of the cave in the next installment of my Platonism series with Aarvoll.
