II. The Fundamental Urge For Knowledge

This feeling makes us strive to bridge over the contrast. And in this bridging the whole spiritual striving of mankind ultimately consists. The history of man's spiritual life is an incessant search for unity between us and the world. Religion, art and science all have this same aim. In the revelation God grants him, the religious believer seeks the solution of the problems in the world which his I, dissatisfied with the world of mere phenomena, sets him. The artist seeks to imprint into matter the ideas of his I, in order to reconcile with the world outside what lives within him. He, too, feels dissatisfied with the world as it appears to him, and seeks to embody into the world of mere phenomena that something more which his I, reaching out beyond it, contains. The thinker seeks the laws of phenomena, and strives to penetrate with thinking what he experiences by observing. Only when we have made the world-content into our thought-content do we again find the unity from which we separated ourselves. We shall see later that this goal will be reached only when the task of the scientific investigator is understood at a much deeper level than is usually the case. The whole situation I have described here, presents itself to us on the stage of history in the contrast between a unified view of the world or monism,[^1] and the theory of two worlds or dualism.[^2] Dualism pays attention only to the separation between I and world, brought about by man's consciousness. All its efforts consist in a vain struggle to reconcile these opposites, which it calls spirit and matter, subject and object, or thinking and phenomena. The dualist feels that there must be a bridge between the two worlds, but he is unable to find it. In as far as man is aware of himself as “I,” he cannot but think of this “I” as belonging to spirit; and in contrasting this “I” with the world he cannot do otherwise than reckon the perceptions given to the senses, the realm of matter, as belonging to the world. In doing so, man places himself within the contrast of spirit and matter. He must do so all the more because his own body belongs to the material world. Thus the “I” belongs to the realm of spirit, as part of it; the material things and events which are perceived by the senses belong to the “world.” All the problems connected with spirit and matter, man finds again in the fundamental riddle of his own nature. Monism pays attention only to the unity and tries either to deny or to efface the contrasts, which are there nevertheless. Neither of these two views is satisfactory, for they do not do justice to the facts. Dualism sees spirit (I) and matter (world) as two fundamentally different entities and cannot, therefore, understand how they can interact upon each other. How should spirit know what goes on in matter, if the essential nature of matter is quite alien to spirit? And how, in these circumstances, should spirit be able to act upon matter, in order to transform its intentions into actions? The most clever and the most absurd hypotheses have been put forward to solve these problems. But, so far, monism has fared no better. Up to now it has tried to justify itself in three different ways. Either it denies spirit and becomes materialism; or it denies matter and seeks its salvation in spiritualism;[^3] or it maintains that since even in the simplest entities in the world spirit and matter are indivisibly bound together, there is no need for surprise if these two kinds of existence are both present in the human being, for they are never found apart.
