If a bell failed to ring, if a stove smoked, if a wheel on a machine stuck, you knew at once where to look and did so with alacrity; you found the defect and knew how to cure it. But the thing within you, the secret mainspring that alone gave meaning to life, the thing within us that alone is living, alone is capable of feeling pleasure and pain, of craving happiness and experiencing it- that was unknown. You knew nothing about that, nothing at all, and if the mainspring failed there was no cure. Wasn't it insane? - Hermann Hesse
