"While discussing what it is that makes the “pleasures of wealth and greatness ... strike the imagination as something grand and beautiful,” [Adam Smith] remarks that “in the languor of disease and the weariness of old age” we cease to be so impressed, for we then take note of the fact that the acquisition of wealth and greatness leaves their possessors “always as much, and sometimes more exposed than before, to anxiety, to fear, and to sorrow, to diseases, to danger, and to death” (The Theory of Moral Sentiments IV, chapter I). But to allow our attention to dwell on this is, on Smith’s view, misguided. To do so is to embrace a “splenetic philosophy,” the effect of “sickness or low spirits” upon an imagination “which in pain and sorrow seems to be confined,” so that we are no longer “charmed with the beauty of that accommodation which reigns in the palaces and economy of the great.” The imagination of those “in better health or in better humor” fosters what may, Smith concedes, be no more than seductive illusions about the pleasures of wealth and greatness, but they are economically beneficial illusions. “It is this deception which rouses and keeps in continual motion the industry of mankind.” So even someone as perceptive as Smith, when he does pause to recognize the perspectives of ill health and old age, finds reason at once to put them on one side. And in so doing Smith speaks for moral philosophy in general."
