Experiences are passed on from one man to another. Abel knew that. And now we know it. But where is the bridge placed?—at the end of the road or only at the end of our vision? Is it all a bridge?—or is there no bridge because there is no gulf? Suppose that a composer writes a piece of music conscious that he is inspired, say, by witnessing an act of great self-sacrifice—another piece by the contemplation of a certain trait of nobility he perceives in a friend's character—and another by the sight of a mountain lake under moonlight. (Charles Ives, 1845)
