Wisdom must be the Master, science the servant. Science is the handmaid of wisdom; wisdom the queen. Science is a product of man’s imagination; wisdom the spiritual recognition of truth. Material science is a product of the essentially selfish desire to know; wisdom recognises no separation of interests, it is the self-recognition of universal and eternal truth in man. Science, guided by wisdom, can enter into the deepest mysteries of universal being by entering into the Unity of the All; but if science attempts to employ wisdom for the gratification of curiosity or other selfish ends, it is in opposition to wisdom and becomes folly. Therefore a favourite motto of the ancient Rosicrucians (of which Theophrastus Paracelsus was one), but which is understood by only a few, said: “_I know nothing, I desire nothing, I love nothing, I enjoy nothing in heaven or upon the earth but Jesus Christ and him crucified._” This did not mean that they resolved to remain ignorant, or to lose themselves in pious reveries and dreams of past events, for Paracelsus also said: “God does not desire us to be ignorant blockheads and stupid fools”—but it meant that they had given up the whole of the illusion of self with all its necessarily illusive knowledge, desires, attractions and joys, and entered into the consciousness of that divine intelligence which during this earth-life is as it were crucified in man, and by entering into the higher spiritual state they had become one with Him, who is Himself the Truth in themselves and the source of all knowledge in heaven and upon the earth.
