Immanuel Kant
Philosopher · 1724–1804
Kant rescued reason from Hume's skepticism but at a profound cost to the interior life. His Critique of Pure Reason (1781) drew an impassable line between phenomena (things as they appear to us) and noumena (things as they are in themselves). The noumenal world — including the soul, God, and freedom — is real but unknowable by theoretical reason. Feeling becomes merely subjective. The interior becomes inaccessible to knowledge. What Homer experienced as the most concrete reality of human life — the thumos seething, the phrenes blackening, the kradie barking — Kant would classify as phenomenal appearances with no guaranteed connection to anything real.

What Did Kant Wall Off?
Kant’s critical philosophy is the most sophisticated version of the Enlightenment’s exile of feeling. By declaring the noumenal world unknowable, he did not deny the soul’s existence. He made it irrelevant to knowledge. The practical consequence is that everything depth psychology studies — the unconscious, the archetypes, the autonomous complex, the soul’s structure — falls on the noumenal side of Kant’s divide and is therefore, by his criteria, not a legitimate object of scientific knowledge. When Jung insisted that the psyche is empirically real and its contents can be studied through their effects, he was directly challenging the Kantian framework that had governed Western thought for two centuries.
