It all depends on how sensitive the soul may become to discords. “The trouble with me is that I believe too much in common happiness and goodness,” said a friend of mine whose consciousness was of this sort, “and nothing can console me for their transiency. I am appalled and disconcerted at its being possible.” And so with most of us: a little cooling down of animal excitability and instinct, a little loss of animal toughness, a little irritable weakness and descent of the pain-threshold, will bring the worm at the core of all our usual springs of delight into full view, and turn us into melancholy metaphysicians. The pride of life and glory of the world will shrivel. It is after all but the standing quarrel of hot youth and hoary eld. Old age has the last word: the purely naturalistic look at life, however enthusiastically it may begin, is sure to end in sadness.
This sadness lies at the heart of every merely positivistic, agnostic, or naturalistic scheme of philosophy. Let sanguine healthy-mindedness do its best with its strange power of living in the moment and ignoring and forgetting, still the evil background is really there to be thought of, and the skull will grin in at the banquet. In the practical life of the individual, we know how his whole gloom or glee about any present fact depends on the remoter schemes and hopes with which it stands related. Its significance and framing give it the chief part of its value. Let it be known to lead nowhere, and however agreeable it may be in its immediacy, its glow and gilding vanish. The old man, sick with an insidious internal disease, may laugh and quaff his wine at first as well as ever, but he knows his fate now, for the doctors have revealed it; and the knowledge knocks the satisfaction out of all these functions. They are partners of death and the worm is their brother, and they turn to a mere flatness.
