The soul is a tabula rasa, all four maintain, a white paper on which, to begin with, nothing is inscribed. It brings with it neither innate knowledge nor commands. What it possesses in the way of percepts, concepts, opinions, convictions, principles of action, rules of conduct, are inscribed upon it through experience (empiricism). That is, not antecedent to, but subsequent to experience (a posteriori). But experience can only be gained through the senses. Only thus does reality penetrate into and stamp itself upon us. “What was not first in the senses (sensus) cannot be in the intelligence.” What the senses convey to us alone builds up our mental content, from mere sensory perceptions upwards to the most abstract ideas from the simplest psychical elements up to the most complex ideas, concepts, and conclusions, to the most varied imaginative constructions. And in the development of the mental content the “soul” itself is merely the stage upon which all that is acquired through the senses crowds, and jostles, and unites to form images, perceptions, and precepts. But it is itself purely passive, and it becomes what happens to it. Therefore it is not really spirit at all, for spirit implies spontaneity, activity, and autonomy.
Philosophy and the mental sciences have always had to carry on the strife with these four opponents. And it is in the teacup of logic and epistemology [pg 294] that the storm in regard to theories of the universe has arisen. It is there, and not in the domain of neurology, or zoology, that the real battlefield lies, upon which the controversy must be fought out to the end. What follows is only a sort of skirmish about the outposts.
What naturalism holds in regard to the psychical and spiritual may be, perhaps, most simply expressed by means of an illustration. Over a wide field there glide mighty shadows in constant interplay. They expand and contract, become denser or lighter, disappear for a little, and then reveal themselves again. While they are thus forming and changing, one state follows quite connectedly on another. At first one is tempted to believe that they are self-acting and self-regulating, that they move freely and pass from one state to another according to causes within themselves. But then one sees that they are thrown upon the earth from the clouds above, now in this way and now in that, that all their states and forms and changes are nothing in themselves, and neither effect anything in themselves nor react upon the occurrences and realities up above, which they only accompany, and by which they are determined without any co-operation on their own part, even in determining their own form. So it is with nature and spirit. Nature is the true effective reality; spirit is its shadow, which effects nothing either within or outside of itself, but simply happens.
The Fundamental Answer.
How can the religious conception of the world justify itself and maintain its freedom in face of such views of spirit and spiritual being? It is questionable whether it is worth while attempting to do so. Is not the essence of the validity and freedom of spirit made most certain simply through the fact that it is able to inquire into it? If we leave popular naturalism out of the question, is not the attempt made by scientific naturalism the best witness against itself? For scientific study, and the establishment of fundamental conceptions and guiding principles are only possible if mind and thought are free and active and creative. The direct experience that spirit has of itself, of its individuality and freedom, of its incomparability with all that is beneath it, is far too constant and genuine to admit of its being put into a difficulty by a doctrine which it has itself established. And this doctrine has far too much the character of a “fixed theory” to carry permanent inward conviction with it. Here again, the mistake made is in starting with scepticism and with the fewest and simplest assumptions. It is by no means the case that in order to discover the truth we must start always from a position of scepticism, instead of from calm confidence in ourselves and in our conviction that we possess in direct experience the best guarantee of truth. For we experience nothing more certainly than the content and riches of our own [pg 296] mind, its power of acting and creating, and all its great capacities. And it is part of the duty laid upon us by the religious conception of the universe, as well as by all other idealistic conceptions, to follow this path of self-assurance alone, that is, through self-development and self-deepening, through self-realisation and self-discipline, to use to the full in our lives all that we have in heart and mind as possibilities, tendencies, content, and capacities, and so practically to experience the reality and power of the spiritual that the mood of suspicion and distrust of it must disappear. The validity of this method is corroborated by all the critical insight into the nature of our knowledge that we have gained in the course of our study, and it might be deepened in regard to this particular case. For here, if anywhere, we must recognise the limitations of our knowledge; the impossibility of attaining to a full understanding of the true nature and depths of things applies to the inquiring mind and its hidden nature. From Descartes to Leibnitz, Kant, and Fries, down to the historian of materialism itself, F. A. Lange, it has been an axiom of the idealistic philosophy, expressed now in dogmatic, now in critical form, that the mathematical-mechanical outlook and causal interpretation of things, not excluding a naturalistic psychology, is thoroughly justifiable as a method of arranging scientifically the phenomena accessible to us and of penetrating more deeply towards an understanding of these. It is, indeed, justifiable, so long as it does not profess [pg 297] to reveal the true nature of things, but remains conscious of the free spirit, whose own work and undertaking the whole is.
Yet here again it is by no means necessary to surrender to naturalism a field which it has tried to take possession of, but is certainly unable to hold. We need not try to force naturalism to read out of empirical psychology the high conclusions as to human nature and spirit which pertain to the religious outlook, or to find in the “simplicity” of the “soul monad” a kind of physical proof of its indestructibility, or anything of that kind. We maintain that to comprehend the true inwardness of the vitality, freedom, dignity, and power of the spirit is not the business of psychology at all, but may perhaps be dealt with in ethics, if it be not admitted that with these concepts one has already entered the realm of religious experience, and that they are the very centre of religious theory. But undoubtedly we must reject in great measure the claims which naturalism makes upon our domain, and maintain that the most important starting-points for the higher view are to be found in the priority of everything spiritual over everything material, in the underivability of the spiritual and the impossibility of describing it in corporeal-mathematical terms and concepts.
Individual Development.
What lives in us, as far as we can perceive and trace it in its empirical expression, is not a finished and spiritual being that leaps, mature and complete, from some pre-existence or other into its embodied form, but is obviously something that only develops and becomes actual very gradually. Its becoming is conditioned by “stimuli,” influences, impressions from without, and perfects itself in the closest dependence upon the becoming of the body, is inhibited or advanced with it, and may be entirely arrested by it, forced into abnormal developments which never attain to the level of an “ego” or “personality,” but remain incomprehensible anomalies and monstrosities. In general, the psychical struggles slowly and laboriously free from purely vegetative and physiological processes, and gains control over itself and over the body. Its self-development and concentration to full unity and completeness of personality is only achieved through the deepest self-culture, through complete “simplification” as the ancients said, through great acts and experiences of inward centralisation such as that which finds religious expression in the metaphor of “regeneration.” What “building up” and self-development of the psychical means remains obscure. If we think of it as a summation, an adding on of new parts and constituents, and thus try to form a concrete image of the process, we spoil it altogether. If we speak of the transition from the potential to the actual, [pg 299] from the tendency to the realisation, we may not indeed spoil it, but we have done little to make the process more intelligible. So much only we can say: certain as it is that the Psyche, especially as conscious inner life, only gradually develops and becomes actual, and that in the closest dependence upon the development, maturing, and establishment of the nervous basis and the bodily organisation in general, yet the naturalistic view, a fortiori the materialistic, is never at any point correct. There are three things to be borne in mind. First, the origin, the “whence” of the psychical is wholly hidden from us, and, notwithstanding the theory of evolution and descent, it remains an insoluble riddle. And secondly, however closely it is associated with and tied down to the processes of bodily development, it is never at any stage of its development really a function of it in actual and exact correspondence and dependence. And finally, the further it advances in its self-realisation, the further the relation of dependence recedes into the background, and the more do the independence and autonomy of the psychical processes become prominent.
