Nothing is good in the life of a human being except the very best that his nature can achieve. As men advance, things which have been good cease to be good, merely because something better is possible. So it is with the life of instinct: for those whose mental life is strong, much that was really good while mind remained less developed has now become bad merely through the greater degree of truth in their outlook on the world. The instinctive man in love feels that his emotion is unique, that the lady of his heart has perfections such as no other woman ever equaled. The man who has acquired the power of impersonal thought realizes, when he is in love, that he is one of so many millions of men who are in love at this moment, that not more than one of all the millions can be right in thinking his love supreme, and that it is not likely that that one is oneself. He perceives that the state of being in love in those whose instinct is unaffected by thought or spirit, is a state of illusion, serving the ends of Nature and making a man a slave to the life of the species, not a willing minister to the impersonal ends which he sees to be good. Thought rejects this slavery; for no end that Nature may have in view will thought abdicate, or forgo its right to think truly. “Better the world should perish than that I or any other human being should believe a lie”—this is the religion of thought, in whose scorching flames the dross of the world is being burnt away. It is a good religion, and its work of destruction must be completed. But it is not all that man has need of. New growth must come after the destruction, and new growth can come only through the spirit.
Both patriotism and the love of man and woman, when they are merely instinctive, have the same defects: their exclusions, their enclosing walls, their indifference or hostility to the outside world. It is through this that thought is led to satire, that comedy has infected what men used to consider their holiest feelings. The satire and the comedy are justified, but not the death of instinct which they may produce if they remain in supreme command. They are justified, not as the last word of wisdom but as the gateway of pain through which men pass to a new life, where instinct is purified and yet nourished by the deeper desires and insight of spirit.
