“NO man was more filled with the sense of this bellicose basis of all cheerfulness than Dickens. He knew very well the essential truth, that the true optimist can only continue an optimist so long as he is discontented. For the full value of this life can only be got by fighting; the violent take it by storm. And if we have accepted everything, we have missed something ─ war. This life of ours is a very enjoyable fight, but a very miserable truce.”
~G.K. Chesterton: Charles Dickens, Ch. XI ─ On the Alleged Optimism of Dickens.
