When we pass to _Materialism_ in its various forms, we find Eucken conscious of its poverty and its caricature of life. It is caused by excessive absorption in the sensuous object with all its manifold relations. But it is possible to believe in all that it states; for it can never really say anything concerning the deeper meaning of spiritual life if for no other reason than that it cannot penetrate into life's deeper experiences. It is a stage in human thought which is passing away. What will become of it after Professor Haeckel's passing is difficult to imagine. One thing at least is certain: as a complete system of the universe or of life it is doomed.[74] A mechanical interpretation of the universe is legitimate: we may have to adopt more of such interpretations in the future. But there is no need for any alarm from the sides of philosophy and religion. Their citadel is not built upon a _thing_, but upon a _thought_; and the gap between the two increases in the degree in which our knowledge of Nature and Man increases. Eucken has many great things to say on this subject in his larger works. Doubtless he would agree with some of the [p.213] advocates of _Naturalism_ in regard to the meaning of the physical universe, but such agreement would not be an admission that _all_ had been said that could be said concerning the need and the possibility of a _Metaphysic of Life_. The one word _More_ constitutes all the difference. This _More_, with Eucken, is the beginning of a new order of existence and of value where the physical order ends. His work consists in interpreting this _More_, and we have already seen whither the _More_ leads us: it leads us into spiritual norms and their values, and these in their turn led us into Infinite Love in the Godhead. The failure to see the value of all this is due to the inattention of the advocates of Naturalism in regard to the non-sensuous structure of mind: the _Thing and its relations_ monopolise them so completely that they are blind to every reality non-sensuous in its nature, although they possess some amount of such reality in their very knowledge and adoration of the _Thing_. Our troubles will continue to accumulate, and the prospect of the future will grow extremely dark, if the grip which physical things have on the world to-day be not relaxed. The very physical powers which we have helped to create, and which hitherto have proved of service to men, will mean our destruction unless something of the _More_ which is beyond them be found as a possession and an activity within the governing centre of life. This is Eucken's [p.214] plea over against the various forms of the Naturalism and Materalism of our day. These are not enough for man. But man is so slow in recognising this fact. The appeal of Spiritual Idealism is considered to be something which is vague and useless. Our deepest reality and the source of all true energy have been robbed of
