Philosophy is really free.

But this practically means only that the prisoner's cell has become the madman's cell: that it is scrawled all over inside with stars and systems, so that it looks like eternity.

This is the contradiction remarked by Dr.Sarolea, in his brilliant book, between the wildness of German theory and the tameness of German practice.

The Germans _sterilise_ thought, making it active with a wild virginity; which can bear no fruit.
But though there are so many mad theories, most of them have one root; and depend upon one assumption.

It matters little whether we call it, with the German Socialists, "the Materialist Theory of History"; or, with Bismarck, "blood and iron." It can be put most fairly thus: that all _important_ events of history are biological, like a change of pasture or the communism of a pack of wolves.
