Columbus of the psyche

From the Pillars of Unbelief series, by Peter Kreeft, Boston College.

"Freud was a scientist, and in some ways a great one. But he succumbed to an occupational hazard: the desire to reduce the complex to the controllable. He wanted to make psychology into a science, even an exact science. But this it can never be because its object, man, is not only an object but also a subject, an 'I.'"
