Therefore man must be on his guard against this cup of enchantments, and must look at nature with a supernatural eye. By piety alone, by conversing with the cause of nature, is he safe and commands it. And because all knowledge is assimilation to the object of knowledge, as the power or genius of nature is ecstatic, so must its science or the description of it be. The poet must be a rhapsodist: his inspiration a sort of bright casualty: his will in it only the surrender of will to the Universal Power, which will not be seen face to face, but must be received and sympathetically known. It is remarkable that we have out of the deeps of antiquity in the oracles ascribed to the half fabulous Zoroaster, a statement of this fact, which every lover and seeker of truth will recognize. “It is not proper,” said Zoroaster, “to understand the Intelligible with vehemence, but if you incline your mind, you will apprehend it: not too earnestly, but bringing a pure and inquiring eye. You will not understand it as when understanding some particular thing, but with the flower of the mind. Things divine are not attainable by mortals who understand sensual things, but only the light-armed arrive at the summit.” And because ecstasy is the law and cause of nature, therefore you cannot interpret it in too high and deep a sense. Nature represents the best meaning of the wisest man. Does the sunset landscape seem to you the place of Friendship,--those purple skies and lovely waters the amphitheatre dressed and garnished only for the exchange of thought and love of the purest souls? It is that. All other meanings which base men have put on it are conjectural and false. You cannot bathe twice in the same river, said Heraclitus; and I add, a man never sees the same object twice: with his own enlargement the object acquires new aspects.
