"Circumstances break men's bones; it has never been shown that they break men's optimism."

There are numberless points upon which Dickens is spiritually at one with the poor, that is, with the great mass of mankind. But there is no point in which he is more perfectly at one with them than in showing that there is no kind of connection between a man being unhappy and a man being pessimistic. Sorrow and pessimism are indeed, in a sense, opposite things, since sorrow is founded on the value of something, and pessimism upon the value of nothing. And in practice we find that those poets or political leaders who come from the people, and whose experiences have really been searching and cruel, are the most sanguine people in the world. These men out of the old agony are always optimists; they are sometimes offensive optimists. A man like Robert Burns, whose father (like Dickens's father) goes bankrupt, whose whole life is a struggle against miserable external powers and internal weaknesses yet more miserable -- a man whose life begins grey and ends black -- Burns does not merely sing about the goodness of life, he positively rants and cants about it. Rousseau, whom all his friends and acquaintances treated almost as badly as he treated them -- Rousseau does not grow merely eloquent, he grows gushing and sentimental, about the inherent goodness of human nature. Charles Dickens, who was most miserable at the receptive age when most people are most happy, is afterwards happy when all men weep. Circumstances break men's bones; it has never been shown that they break men's optimism. These great popular leaders do all kinds of desperate things under the immediate scourge of tragedy. They become drunkards; they become demagogues; they become morphomaniacs. They never become pessimists. Most unquestionably there are ragged and unhappy men whom we could easily understand being pessimists. But as a matter of fact they are not pessimists. Most unquestionably there are whole dim hordes of humanity whom we should promptly pardon if they cursed God. But they don't. The pessimists are aristocrats like Byron; the men who curse God are aristocrats like Swinburne. But when those who starve and suffer speak for a moment, they do not profess merely an optimism, they profess a cheap optimism; they are too poor to afford a dear one. They cannot indulge in any detailed or merely logical defence of life; that would be to delay the enjoyment of it. These higher optimists, of whom Dickens was one, do not approve of the universe; they do not even admire the universe; they fall in love with it. They embrace life too close to criticise or even to see it. Existence to such men has the wild beauty of a woman, and those love her with most intensity who love her with least cause.

-Charles Dickens (1906)
