The individual is the only real thing in nature and in life. Neither the species, the genus, nor the race, actually exists; they are abstractions, terminologies, scientific devices, useful as syntheses but not entirely exact. By means of these devices we can discuss and compare; they constitute a measure for our minds to use, but have no external reality. People of today, remote from nature and nasal rings, live in an artificial moral harmony which does not exist except in the imagination of those ridiculous priests of optimism who preach from the columns of the newspapers. This imaginary harmony makes us abhor the contradictions, the incongruities of individuality, at least it forces us not to understand them.
