He was still quite a young man; his depression did not come from age. In fact, as far as I know, mere depression never does come from mere age. Age can pass into a beautiful reverie. Age can pass into a sort of beautiful idiocy. But I do not think that the actual decline and close of our ordinary vitality brings with it any particular heaviness of the spirits. The spirits of the old do not as a rule seem to become more and more ponderous until they sink into the earth. Rather the spirits of the old seem to grow lighter and lighter until they float away like thistledown. Wherever there is the definite phenomenon called depression, it commonly means that something else has been closer to us than so normal a thing as death. There has been disease, bodily or mental, or there has been sin, or there has been some struggle or effort, breaking past the ordinary boundaries of human custom. In the case of Dickens there had been two things that are not of the routine of a wholesome human life; there had been the quarrel with his wife, and there had been the strain of incessant and exaggerated intellectual labour. He had not an easy time; and on top of that (or perhaps rather at the bottom of it) he had not an easy nature. Not only did his life necessitate work, but his character necessitated worry about work; and that combination is always one which is very dangerous to the temperament which is exposed to it. The only people who ought to be allowed to work are the people who are able to shirk. The only people who ought to be allowed to worry are the people who have nothing to worry about. When the two are combined, as they were in Dickens, you are very likely to have at least one collapse. _Little Dorrit_ is a very interesting, sincere, and fascinating book. But for all that, I fancy it is the one collapse.
