If I can reconcile myself to the certainty of death only by forgetting it, I am not happy. And if I can dispose of the fact of human misery about me only by shutting my thoughts as well as myself within my comfortable garden, I may assure myself that I am happy, but I am not. There is a skeleton in the closet of the universe, and I may at any moment be in the face of it. Happiness is inseparable from confidence in action; and confidence of action is inseparable from what the schoolmen called peace -- that is, poise of mind with reference to everything I may possibly encounter in the chances of fortune.
