II. The Fundamental Desire for Knowledge
How do matters stand with the spiritualistic view? The pure spiritualist denies matter in its independent existence and apprehends it only as product of the spirit. If he applies this world view to solving the riddle of his own human nature, he is, in doing so, driven into a corner. Confronting the “I,” which can be placed on the side of spirit, there stands, without intermediary, the sensory world. Into this, no spiritual entry seems to open; this world has to be perceived and experienced by the “I” through material processes. The “I” does not find any such material processes within itself, if it wants to be considered only as a spiritual entity. The sense world is never present in what the “I” works through spiritually for itself. It seems the “I” must admit that the world would remain closed to it, if the “I” were not to put itself into a relationship with it in an unspiritual way. In like manner, when we come to act, we must transform our intentions into reality with the help of the material substances and forces. We are, therefore, reliant on the outer world. The most extreme spiritualist, or if you will, the thinker presenting himself as extreme spiritualist through absolute idealism, is Johann Gottlieb Fichte. He attempted to derive the whole edifice of the world out of the “I.” What he actually achieved thereby is a magnificent thought picture of the world, without any content of experience. Just as little as it is possible for the materialist to banish spirit by decree, it is possible for the spiritualist to banish the outer material world by decree.
