As to the morality or immorality of the char acters that I picture, I concern myself no more with this than I would with the morality or immorality of bees or ants, if I were describing the life of those creatures. I picture human life as I see it. I know that in the social order the immorality of today may become the highest morality of tomorrow. I know that the bitter persecution of truth on the part of ignorance, in the name of morality, has characterized the whole history of the race. I write in the interests of scientific truth which endures, not in the interests of morality, which vanisheth away.
