The chief advantage that would result from the establishment of Socialism is, undoubtedly, the fact that Socialism would relieve us from that sordid necessity of living for others which, in the present condition of things, presses so hardly upon almost everybody. In fact, scarcely anyone at all escapes. Now and then, in the course of the century, a great man of science, like Darwin; a great poet, like Keats; a fine critical spirit, like M. Renan; a supreme artist, like Flaubert, has been able to isolate himself, to keep himself out of reach of the clamorous claims of others, to stand "under the shelter of the wall," as Plato puts it, and so to realise the perfection of what was in him, to his own incomparable gain, and to the incomparable and lasting gain of the whole world.
