“ THE FREEDOM OF THE SOUL.—The human soul is endowed with freedom to do good or evil. What proof is there of this freedom? First, the inward feeling that we have. Every evident idea is true. Now, not only have we the idea of this freedom, but it would be impossible for us not to have it. Freedom "is known without proofs, merely by the experience we have of it." It is by the feeling of our freedom, of our free-will that we understand that we exist as a being, as a thing which is not merely a thing. The true ego is the will. ”
