A curious variant of Idealism is to be found in the theory which F. A. Lange has put forward in his widely read History of Materialism. He holds that the Materialists are quite right in declaring all phenomena, including our thoughts, to be the product of purely material processes, but, in turn, Matter and its processes are for him themselves the product of our thinking. "The senses give us only the effects of things, not true copies, much less the things themselves. But among these mere effects we must include the senses themselves together with the brain and the molecular vibrations which we assume to go on there." That is, our thinking is produced by the material processes, and these by our thinking. Lange's philosophy is thus nothing more than the philosophical analogon of the story of honest Baron Münchhausen, who holds himself up in the air by his own pigtail. The third form of Monism is that which finds even in the simplest real (the atom) the union of both Matter and Mind. But nothing is gained by this either, except that the question, the origin of which is really in our consciousness, is shifted to another place. How comes it that the simple real manifests itself in a two-fold manner, if it is an indivisible unity? Against all these theories we must urge the fact that we meet with the basal and fundamental opposition first in our own consciousness. It is we ourselves who break away from the bosom of Nature and contrast ourselves as Self with the World. Goethe has given classic expression to this in his essay Nature. "Living in the midst of her (Nature) we are strangers to her. Ceaselessly she speaks to us, yet betrays none of her secrets." But Goethe knows the reverse side too: "Mankind is all in her, and she in all mankind." However true it may be that we have estranged ourselves from Nature, it is none the less true that we feel we are in her and belong to her. It can be only her own life which pulses also in us. We must find the way back to her again. A simple reflection may point this way out to us. We have, it is true, torn ourselves away from Nature, but we must none the less have carried away something of her in our own selves. This quality of Nature in us we must seek out, and then we shall discover our connection with her once more. Dualism neglects to do this. It considers the human mind as a spiritual entity utterly alien to Nature and attempts somehow to hitch it on to Nature. No wonder that it cannot find the coupling link. We can find Nature outside of us only if we have first learnt to know her within us. The Natural within us must be our guide to her. This marks out our path of inquiry. We shall attempt no speculations concerning the interaction of Mind and Matter. We shall rather probe into the depths of our own being, to find there those elements which we saved in our flight from Nature.
