Various criticisms on the part of philosophers with which this book met immediately upon its publication, induce me to add to this Revised Edition the following brief statement.

I can well understand that there are readers who are interested in the rest of the book, but who will look upon what follows as a tissue of abstract concepts which to them is irrelevant and makes no appeal. They may, if they choose, leave this brief statement unread. But in philosophy problems present themselves which have their origin rather in certain prejudices on the thinker’s part than in the natural progression of normal human thinking. With the main body of this book it seems to me to be the duty of every one to concern himself, who is striving for clearness about the essential nature of man and his relation to the world. What follows is rather a problem the discussion of which certain philosophers demand as necessary to a treatment of the topics of this book, because these philosophers, by their whole [358]way of thinking, have created certain difficulties which do not otherwise occur. If I were to pass by these problems entirely, certain people would be quick to accuse me of dilettantism, etc. The impression would thus be created that the author of the views set down in this book has not thought out his position with regard to these problems because he has not discussed them in his book.

The problem to which I refer is this: there are thinkers who find a particular difficulty in understanding how another mind can act on one’s own. They say: the world of my consciousness is a closed circle within me; so is the world of another’s consciousness within him. I cannot look into the world of another’s mind. How, then, do I know that he and I are in a common world? The theory according to which we can from the conscious world infer an unconscious world which never can enter consciousness, attempts to solve this difficulty as follows. The world, it says, which I have in my consciousness is the representation in me of a real world to which my consciousness has no access. In this transcendent world exist the unknown agents which cause the world in my consciousness. In it, too, exists my own real self, of which likewise I have only a representation in my consciousness. In it, lastly, exists the essential self of the fellow-man who confronts me. Whatever passes in the consciousness of my fellow-man corresponds to a reality in his transcendent essence which is [359]independent of his consciousness. His essential nature acts in that realm which, on this theory, is equally beyond consciousness. Thus an impression is made in my consciousness which represents there what is present in another’s consciousness and wholly beyond the reach of my direct awareness. Clearly the point of this theory is to add to the world accessible to my consciousness an hypothetical world which is to my immediate experience inaccessible. This is done to avoid the supposed alternative of having to say that the external world, which I regard as existing before me, is nothing but the world of my consciousness, with the absurd—solipsistic—corollary that other persons likewise exist only within my consciousness.

Several epistemological tendencies in recent speculation have joined in creating this problem. But it is possible to attain to clearness about it by surveying the situation from the point of view of spiritual perception which underlies the exposition of this book. What is it that, in the first instance, I have before me when I confront another person? To begin with, there is the sensuous appearance of the other’s body, as given in perception. To this we might add the auditory perception of what he is saying, and so forth. All this I apprehend, not with a passive stare, but by the activity of my thinking which is set in motion. Through the thinking with which I now confront the other person, the percept of him becomes, as it were, psychically transparent. As my thinking [360]apprehends the percept, I am compelled to judge that what I perceive is really quite other than it appears to the outer senses. The sensuous appearance, in being what it immediately is, reveals something else which it is mediately. In presenting itself to me as a distinct object, it, at the same time, extinguishes itself as a mere sensuous appearance. But in thus extinguishing itself it reveals a character which, so long as it affects me, compels me as a thinking being to extinguish my own thinking and to put its thinking in the place of mine. Its thinking is then apprehended by my thinking as an experience like my own. Thus I have really perceived another’s thinking. For the immediate percept, in extinguishing itself as sensuous appearance, is apprehended by my thinking. It is a profess which passes wholly in my consciousness and consists in this, that the other’s thinking takes the place of my thinking. The self-extinction of the sensuous appearance actually abolishes the separation between the spheres of the two consciousnesses. In my own consciousness this fusion manifests itself in that, so long as I experience the contents of the other’s consciousness, I am aware of my own consciousness as little as I am aware of it in dreamless sleep. Just as my waking consciousness is eliminated from the latter, so are the contents of my own consciousness eliminated from my perception of the contents of another’s consciousness. Two things tend to deceive us about the true facts. [361]The first is that, in perceiving another person, the extinction of the contents of one’s own consciousness is replaced not, as in sleep, by unconsciousness, but by the contents of the other’s consciousness. The other is that my consciousness of my own self oscillates so rapidly between extinction and recurrence, that these alternations usually escape observation. The whole problem is to be solved, not through artificial construction of concepts, involving an inference from what is in consciousness to what always must transcend consciousness, but through genuine experience of the connection between thinking and perceiving. The same remark applies to many other problems which appear in philosophical literature. Philosophers should seek the road to unprejudiced spiritual observation, instead of hiding reality behind an artificial frontage of concepts.

In a monograph by Eduard von Hartmann on “The Ultimate Problems of Epistemology and Metaphysics” (in the Zeitschrift für Philosophie und philosophische Kritik, Vol. 108, p. 55), my Philosophy of Spiritual Activity has been classed with the philosophical tendency which seeks to build upon an “epistemological Monism.” Eduard von Hartmann rejects this position as untenable, for the following reasons. According to the point of view maintained in his monograph, there are only three possible positions in the theory of knowledge. The first consists in remaining true to the na?ve point of view, which regards objects of [362]sense-perception as real things existing outside the human mind. This, urges Von Hartmann, implies a lack of critical reflection. I fail to realise that with all my contents of consciousness I remain imprisoned in my own consciousness. I fail to perceive that I am dealing, not with a “table-in-itself,” but only with a phenomenon in my own consciousness. If I stop at this point of view, or if for whatever reasons I return to it, I am a Na?ve Realist. But this whole position is untenable, for it ignores that consciousness has no other objects than its own contents. The second position consists in appreciating this situation and confessing it to oneself. As a result, I become a Transcendenta............
