You can tear a poem apart to see what makes it tick... You're back with the mystery of having been moved by words. The best craftsmanship always leaves holes and gaps... so that something that is not in the poem can creep, crawl, flash or thunder in.
Experience was of no ethical value. It was merely the name men gave to their mistakes. Moralists had, as a rule, regarded it as a mode of warning, had claimed for it a certain ethical efficacy in the formation of character, had praised it as something that taught us what to follow and showed us what to avoid. But there was no motive power in experience. It was as little of an active cause as conscience itself. All that it really demonstrated was that our future would be the same as our past, and that the sin we had done once, and with loathing, we would do many times, and with joy.
