The movement of History culminates alternately in _Concentration_ on the one hand, and in _Expansion_ on the other: _Positive_ and _Critical_ epochs alternate. Both aspects are necessary for the growth of life.

In modern times the growth of the Expansion-side of life has destroyed in a large measure the equilibrium of life; and the task to-day is to construct a new Concentration-side.

Such a new Concentration is possible: the experience of History testifies to its presence in several epochs; and there is a deep longing for it in many quarters to-day.

In order to attain to such a Concentration the "dead-level" life of the present must be overcome, and a turn must take place towards a new Metaphysic of Life.

Such is the problem to-day, and no complete answer is to be found in the past systems of Metaphysics. "The possibilities of Life and [p.244] of Knowledge are in no way exhausted, but it is only through our own courage and actions that the possibilities can become actualities"

(_Erkennen und Leben_, p. 161).

The various systems of Thought need a synthesis which will include them all. It is difficult to-day to obtain a theory of life which does not leave out of account some essential elements. Is there a possibility of discovering such a synthesis? I believe that Eucken's works answer this question. But we wait eagerly for the appearance of his greatest work, and I think that, when it appears, he will more than ever deserve Windelband's designation of him as "the creator of a new Metaphysic."
