“How can things so insecure as the successful experiences of this world afford a stable anchorage? A chain is no stronger than its weakest link, and life is after all a chain. In the healthiest and most prosperous existence, how many links of illness, danger, and disaster are always interposed? Unsuspectedly from the bottom of every fountain of pleasure, as the old poet said, something bitter rises up: a touch of nausea, a falling dead of the delight, a whiff of melancholy, things that sound a knell, for fugitive as they may be, they bring a feeling of coming from a deeper region and often have an appalling convincingness. The buzz of life ceases at their touch as a piano-string stops sounding when the damper falls upon it. Of course the music can commence again; –and again and again,– at intervals. But with this the healthy-minded consciousness is left with an irremediable sense of precariousness. It is a bell with a crack; it draws its breath on sufferance and by an accident. Even if we suppose a man so packed with healthymindedness as never to have experienced in his own person any of these sobering intervals, still, if he is a reflecting being, he must generalize and class his own lot with that of others; and, doing so, he must see that his escape is just a lucky chance and no essential difference. He might just as well have been born to an entirely different fortune. And then indeed the hollow security! What kind of a frame of things is it of which the best you can say is, ‘Thank God, it has let me off clear this time!’ Is not its blessedness a fragile fiction? Is not your joy in it a very vulgar glee, not much unlike the snicker of any rogue at his success? If indeed it were an success, even on such terms as that! But take the happiest man, the one most envied by the world, and in nine cases out of ten his inmost consciousness is one of failure. Either his ideals in the line of his achievements are pitched far higher than the achievements themselves, or else he has secret ideals of which the world knows nothing, and in regard to which he inwardly knows himself to be found wanting.” – William James, The Varieties of Religious Experience
