The story does not close with the expulsion from Paradise. We are further told, God said, 'Behold Adam is become as one of us, to know good and evil.' Knowledge is now spoken of as divine, and not, as before, as something wrong and forbidden. Such words contain a confutation of the idle talk that philosophy pertains only to the finitude of the mind. Philosophy is knowledge, and it is through knowledge that man first realises his original vocation, to be the image of God. When the record adds that God drove men out of the Garden of Eden to prevent their eating of the tree of life, it only means that on his natural side certainly man is finite and mortal, but in knowledge infinite. We all know the theological dogma that man's nature is evil, tainted with what is called Original Sin. Now while we accept the dogma, we must give up the setting of incident which represents original sin as consequent upon an accidental act of the first man. For the very notion of spirit is enough to show that man is evil by nature, and it is an error to imagine that he could ever be otherwise. To such extent as man is and acts like a creature of nature, his whole behaviour is what it ought not to be. For the spirit it is a duty to be free, and to realise itself by its own act. Nature is for man only the starting-point which he has to transform. The theological doctrine of original sin is a profound truth; but modern enlightenment prefers to believe that man is naturally good, and that he acts right so long as he continues true to nature. The hour when man leaves the path of mere natural being marks the difference between him, a self-conscious agent, and the natural world. But this schism, though it forms a necessary element in the very notion of spirit, is not the final goal of man. It is to this state of inward breach that the whole finite action of thought and will belongs. In that finite sphere man pursues ends of his own and draws from himself the material of his conduct. While he pursues these aims to the uttermost, while his knowledge and his will seek himself, his own narrow self apart from the universal, he is evil; and his evil is to be subjective.
