The problem is that regarding man as a subject of observation from whatever point of view⁠—theological, historical, ethical, or philosophic⁠—we find a general law of necessity to which he (like all that exists) is subject. But regarding him from within ourselves as what we are conscious of, we feel ourselves to be free.

This consciousness is a source of self-cognition quite apart from and independent of reason. Through his reason man observes himself, but only through consciousness does he know himself.

Apart from consciousness of self no observation or application of reason is conceivable.

To understand, observe, and draw conclusions, man must first of all be conscious of himself as living. A man is only conscious of himself as a living being by the fact that he wills, that is, is conscious of his volition. But his will⁠—which forms the essence of his life⁠—man recognizes (and can but recognize) as free.
