These are the elements of that higher science which the physician of the future will have to learn, first theoretically and afterwards in their practical application. Without a spiritual recognition of the fundamental principles of Nature, a seeking from a superficial point of view for a discovery of the mysteries of being is like an unfruitful wandering in a fog. It resembles a search from the periphery of a sphere of unknown extent for a centre whose locality is unknown; while if we have once a correct conception of the situation of that shining centre, its light will act as a guiding star in our wanderings through the fogs which pervade the realm of phenomena. Science comes from man; wisdom belongs to God. Of sciences there are many; wisdom is only one. The sciences should be cultivated, but wisdom not be neglected, for without wisdom no true science can exist. “Nothing (real) is of ourselves; we do not belong to ourselves, but we belong to God. Therefore we must try to find in ourselves that which is of God. It is his and not ours. He has made a body for us, and given us life and wisdom in addition to it, and from these come all things. We should learn to know the object of our existence, and the reason why man has a soul, and what is the will of God that he should do. A study of (terrestrial) man will never reveal the secret and object of his existence, and the reason why he is in the world; but if we once know his creator, we shall also know the qualities of his child; for he who knows the father knows also the son, because the son inherits the (nature of) the father. Each man has the same amount of truth given to him by God; but not everyone recognises that which he has received. He who sleeps knows nothing; he who lives an idle life does not know the power which is in him, and wastes his time. Man is so great and noble that he bears the image of God, and is an heir to the kingdom of God. God is supreme truth, and the devil is supreme falsehood. Falsehood cannot know truth. Therefore if man wants to come into possession of truth, he must know the wisdom which he has received from God. Cleverness belongs to the animal nature, and in regard to many scientific acquisitions animals are superior to man; but the understanding is an awakening which cannot be taught by man. That which one person learns from another is nothing unless there is an awakening. A teacher can put no knowledge into his pupil, he can only aid in the awakening of the knowledge which is already in him.” (“De Fundamento Sapientiæ,” I.) Wisdom is the recognition of God. God is the truth, the knowledge of one’s own true self is divine wisdom. He who knows his true self knows the divine powers belonging to his God.
