The second permanent strain of human evolution is the development of fine sentiment. The notion that the world is becoming more preponderantly intellectual, and that progress along our present lines means a limitation of sentiment, is inaccurate. We are working toward a healthy equilibrium. Sentimental people--those in whom a starving of intellect or disuse of muscle has surcharged the nervous system with morbid energy--will become more balanced, more intellectual. Ancient phrases and modern shibboleths will not be able to induce in them an instinctive warmth or agitation: they will have to pass the bar of reason before they reach what one might call the executive department of personality. But sentiment--deep and healthy feeling--has a precious use in life. The development of fine sentiment is as necessary as the cultivation of reason to the advance of man and of civilisation. We find this illustrated in all the older civilisations when they reach their highest point. We are picking up this strain of development to-day, and, since civilisation is now too widely diffused ever to perish again, we may assume that it will continue. Now this finer sentiment of our time demands the revision of our traditions and institutions no less imperiously than our higher intelligence does. We cannot leave behind the callousness and brutality of the Middle Ages and at the same time retain medieval practices. Intellectually and emotionally we are improving, and we must expect that, as our finer powers grow, there will be an increasing demand for revision and reconstruction. As Mr. Watson finely says: "Guests of the ages, at tomorrow's door Why shrink we? The long track behind us lies, The lamps gleam and the music throbs before, Bidding us enter; and I count him wise Who loves so well man's noble memories He needs must love man's nobler hopes yet more."
