Let me explain a little: Certain things are bad so far as they go, such as pain, and no one, not even a lunatic, calls a tooth-ache good in itself; but a knife which cuts clumsily and with difficulty is called a bad knife, which it certainly is not. It is only not so good as other knives to which men have grown accustomed. A knife is never bad except on such rare occasions as that in which it is neatly and scientifically planted in the middle of one's back. The coarsest and bluntest knife which ever broke a pencil into pieces instead of sharpening it is a good thing in so far as it is a knife. It would have appeared a miracle in the Stone Age. What we call a bad knife is a good knife not good enough for us; what we call a bad hat is a good hat not good enough for us; what we call bad cookery is good cookery not good enough for us; what we call a bad civilization is a good civilization not good enough for us. We choose to call the great mass of the history of mankind bad, not because it is bad, but because we are better. This is palpably an unfair principle. Ivory may not be so white as snow, but the whole Arctic continent does not make ivory black. Now it has appeared to me unfair that humanity should be engaged perpetually in calling all those things bad which have been good enough to make other things better, in everlastingly kicking down the ladder by which it has climbed. It has appeared to me that progress should be something else besides a continual parricide; therefore I have investigated the dust-heaps of humanity, and found a treasure in all of them. I have found that humanity is not incidentally engaged, but eternally and systematically engaged, in throwing gold into the gutter and diamonds into the sea. I have found that every man is disposed to call the green leaf of the tree a little less green than it is, and the snow of Christmas a little less white than it is; therefore I have imagined that the main business of a man, however humble, is defence. I have conceived that a defendant is chiefly required when worldlings despise the world--that a counsel for the defence would not have been out of place in that terrible day when the sun was darkened over Calvary and Man was rejected of men. * * * * * A DEFENCE OF PENNY DREADFULS One of the strangest examples of the degree to which ordinary life is undervalued is the example of popular literature, the vast mass of which we contentedly describe as vulgar. The boy's novelette may be ignorant in a literary sense, which is only like saying that a modern novel is ignorant in the chemical sense, or the economic sense, or the astronomical sense; but it is not vulgar intrinsically--it is the actual centre of a million flaming imaginations.
