[I]t is only when we think abstractly that we have such a high opinion of man. Of men in the concrete, most of us think the vast majority very bad. Civilized states spend more that half their revenue on killing each other's citizens. Consider the long history of the activities inspired by moral fervor: human sacrifices, persecution of heretics, witch-hunts, pogroms leading up to wholesale extermination by poison gases... Are these abominations, and the ethical doctrines by which they are prompted, really evidence of an intelligent Creator? And can we really wish that the men who practiced them should live forever? The world in which we live can be understood as a result of muddle and accident; but if it is the outcome of deliberate purpose, the purpose must have been that of a fiend. For my part, I find accident a less painful and more plausible hypothesis.
