V. The Activity of Knowing the World

A major question for the proponent of transcendental realism would have to be how the “I” brings about the world of mental pictures out of itself. A serious striving for knowledge about a world of mental pictures given to us, which disappears as soon as we close our senses to the outer world, can kindle itself only to the extent that such a world is a means of investigating indirectly the world of the “I”-in-itself. If the things of our experience were mental pictures, then our everyday life would be like a dream and knowledge of the true state of affairs would be like waking up. Our dream pictures also interest us as long as we are dreaming and therefore not recognizing them in their dream character. The moment we wake up we no longer ask about the inner connections of our dream pictures, but rather about the physical, physiological, and psychological processes that underlie them. Just as little can the philosopher, who considers the world to be his mental picture, interest himself in the inner connections of the details of this world. If he admits to an existing “I” at all, he will not then ask how one of his mental pictures relates to another, but rather what occurs, within the soul existing independently of him, while his consciousness contains a certain train of mental pictures. If I dream that I am drinking wine which causes a burning in my throat, and then wake up with an irritation in my throat that makes me cough (see Weygandt, How Dreams Arise, 1893),[^3] then the moment I wake up, the dream event ceases to have an interest for me. My attention is now directed only toward the physiological and psychological processes through which the irritation in my throat brings itself symbolically to expression in the dream picture. In the same way, as soon as he is convinced that the world given him has the character of mental pictures, the philosopher must skip over this world into the real soul existing behind it. The situation is far worse, to be sure, if illusionism totally denies the “I”-in-itself behind the mental pictures, or at least considers it to be unknowable. One can very easily be led to such a view by the observation that, in contrast to dreaming, there is indeed the waking state, in which we have the chance to see through our dreams and to relate them to real circumstances, but that we have no state which stands in a similar relationship to our life of waking consciousness. Whoever adopts this view lacks the insight that there is something which in fact does relate to mere perceiving in the same way that experience in the waking state relates to dreaming. This something is thinking.
