The failing activity of the old man is centred in his heart, the child's overflowing activity spreads abroad… — Jean Jacques Rousseau

The failing activity of the old man is centred in his heart, the child's overflowing activity spreads abroad. He feels, if we may say so, strong enough to give life to all about him. To make or to destroy, it is all one to him; change is what he seeks, and all change involves action. If he seems to enjoy destructive activity it is only that it takes time to make things and very little time to break them, so that the work of destruction accords better with his eagerness.
