and this requirement is satisfied. And for those who hold the theory,--not infrequently to be heard in socialist circles,--that the course of "evolution" itself must bring the solution of the social question, that it is impossible to set up views and say that they ought to be realised,--to these we shall reply: Most certainly evolution will bring about that which must be; but men's ideas are realities and active impulses within the body social. And when time has gone on a little further, and that has become realised which to-day can only be thought, then these realised thoughts will be there in the evolution. With time, when the thoughts of to-day have become part of evolution, then those, who look to "evolution alone" and have no use for fruitful ideas, may be better able to form a judgment. Only, when that time comes, it will be too late to accomplish certain things, which are required now by the facts of to-day. In the social organism, it is not possible to set about observing the evolution from outside, objectively, as one does in nature. One is obliged to take an active part in the evolutionary process. And it is therefore so disastrous for all sound thought on social matters that it is to-day up against views that are bent on "demonstrating" social requirements as one "demonstrates" a fact in natural science. In the comprehension of social life, there can be no "proof," unless one takes into account not only what is actually present existing, but also that other factor, latent within men's impulses, often unknown to themselves, seed-like and striving towards realisation.
