to this that it asserts itself. In everything, it is only one’s own welfare, the interest of individual preservation, that directly inspires conduct; but real life shows man in so many relations, so closely implicated with his environment, that he can strive for nothing for himself without also striving for others. This extension of interests has no limits; there is nothing in the whole of infinity which could not in this way become to man, indirectly, a means of self-preservation and thus an object of desire.
The naturalistic type of life extends from the most general of impulses to every branch of activity, and forms every department of life in a distinctive fashion. Knowledge depends entirely upon experience; every speculative element must be excluded as a subjective delusion; in all its branches knowledge is nothing else than a broadened Natural Science. Art may not pursue imaginary ideals; it finds its single task in the faithful and simple reproduction of the natural environment. Social life and endeavour will develop, above all, natural powers, and will seek to adapt itself to the conditions given by nature, and, rejecting all aims based upon mere imagination, it will care chiefly for the physical welfare of the whole, as the source of all power and of all success.
It is not difficult to understand how this form of life was able to win and carry away the minds of its contemporaries. In the first place it has the character of simplicity and immediacy, which, in contrast with the complexity and the remoteness of the traditional position, appears a great advantage. For, in this scheme, life, with all its multiplicity, is dominated and unified by the idea of natural self-preservation; and the things which immediately affect us, which lie physically and psychically near to us, come most directly into relation to this aim. It is a further tendency of this scheme of life to bring the whole of existence into a state of activity and restless advance. For the state of conflict which prevails under the naturalistic system allows nothing to persist merely because of its present existence or through the weight of tradition, but everything must always be reasserting its right to existence; it must stretch and extend itself in order to be useful in the life of the present. That which cannot satisfy this test is unmercifully thrown over as a dead weight. It is also of great importance to the theory in question that nature and the world are involved in ceaseless change, and that, along with the conditions of life, the requirements also alter: the matter is one of continually accommodating oneself anew; and so life is placed entirely in the present, and the fixity of an absolute conception and treatment of change yields to the instability of a relative one. Last of all, and most especially, life according to its own conviction bears the character of truth. For human striving appears to attain the firm basis of reality, and to become truthful in itself only when it is definitely related to the surrounding world; while, so long as it trusted to the capacity of the subject—which fondly imagined itself independent—it fell into unspeakable error. Only when delivered from subjectivity, only when fixed within the web of the whole of nature, does life seem to awaken out of a dream, and to become fully real, a genuine, securely grounded life.
The energy of negation which this theory employs and with which it drives out everything which has become old adds strength to the elements of assertion and positive achievement in these changes. In this theory there is nothing indefinite which could soften the opposition, nothing mediatory which could overcome it, but, distinctly and harshly, affirmation and negation stand face to face and call for a plain decision between them. Whatever remains in doubt and under suspicion is forced into the background, indeed eliminated altogether, through the victorious onward march of modern Natural Science and the increasing triumphs of technical skill, which seem to demonstrate, immediately, the truth of the naturalistic type of life. Thus, this movement spreads in a mighty flood through humanity, and seizes with a particular power the classes which are struggling upward, and which meet science and culture with a faith yet undisturbed. In matters temporal there is hardly anything which seems able to withstand such an attack.
Nevertheless, that which gains the support of many contemporaries is not thereby proved to be the supreme power and the final truth. In that movement there may be far more, and something far more important than it itself admits. It may be that it achieves that which it does achieve only with the help of elements of another kind; perhaps, indeed, it is able to maintain its truth only in so far as it enters into broader relations in a wider whole and thereby changes its meaning essentially. Whether such is the case can be ascertained not by reference to subjective opinion, but by an examination of the life of humanity.
Now, the first movement of opposition is produced in just that sphere which seemed Naturalism’s strongest bulwark, that is, Natural Science, the Natural Science based on mathematics and physics. Only the most fleeting survey can lead to the confusion of Natural Science with Naturalism; in reality, the naturalistic thinker cannot with justice acknowledge any exact Natural Science, and a natural scientist cannot be naturalistic in thought in consequence of his science, but only in spite of it. For, Natural Science is anything but a mere copy of the sense impressions which we experience; its origin and progress are due to the fact that thought fundamentally acts upon and transforms those impressions. If our intellect were no more than Naturalism can logically make it out to be, it could, at most, only refine the animal presentations a little; it never could have advanced beyond the single presentations to a representative conception of the world as a whole. Such an advance can be achieved only by thought raising itself above the stream of appearances and placing itself over against it; but how could a mere bundle of perceptions, to which Naturalism reduces the intellect, achieve this? Incomparably more unity of being and freedom of operation are necessary for this achievement than such a bundle could produce.
In earlier times, no doubt, man went very much astray in the interpretation of his environment; he transferred his immediate feelings into it; he coloured the whole world in human colours, and associated with its realities as with beings of the same nature as himself. But even the error shows a seeking and an interpretation; the simple putting of the question proclaims a being becoming superior to mere nature. The most important thing, however, is that man has not regarded the matter as finally settled with this anthropomorphism; he has come to regard it as inadequate and has pressed forward to a new way of thinking. What could drive him to that change but a desire for truth, and how is such a conception as truth attainable from nature? And if thought has succeeded in breaking through the misty veil of anthropomorphism and seeks things in their own relations; if an objective consciousness of the world has emerged, a consciousness which is as different from the immediacy of sense impressions as the sky is distant from the earth, has not man also grown in himself beyond mere sense impression; is it not a work of thought which supports and governs the whole construction, and differentiates genuine nature from appearance? How much power of comprehension and of relating together is exhibited even by Natural Science, in that it analyses the sense presentation of the environment into its single elements, ascertains the laws of these, and traces the movement from the simplest beginnings right up to its present stage of development. All activity of thought is thus subject to a certain reproach in that it must continually bring itself into relation to perception: nevertheless it will interweave all that is imparted to it by perception into a framework of thought—transform it, in fact, into a realm of thought. Spirituality is bound; but how dull an individual must be to confuse such a bound spirituality with mere sensuousness!
The error of Naturalism is obvious; concerned solely with the object and its form, it entirely leaves out of account the psychical activity which is involved in the perception of an object; it overlooks the life-process within which alone we can have knowledge of an object and occupy ourselves with it. As soon, however, as we regard the object from this point of view, it will be transformed and will assume far more spiritual traits. Reality will then burst asunder the framework into which Naturalism desires to press it.
The type of life which Naturalism gives rise to also contains more than Naturalism is able to explain. At first sight it seems as though man is taken up completely into a wider conception of nature; as though his life obeys its forces and impulses exclusively; as though all his asserted superiority to nature is simply imaginary. As a matter of fact, in this turning to nature, man, with his spiritual activity, stands not within, but above, nature. For he does not appear as a mere piece of nature, but experiences it and thinks over it: its kingdom, its organisation, its stability become to him a joyful possession and a widening of his being. The spiritual life has developed in relation to nature; nature has not welded it together.
