"The border between music and noise is always culturally defined—which implies that, even within a single society, this border does not always pass through the same place; in short, there is rarely a consensus.... By all accounts there is no single and intercultural universal concept defining what music might be"

Since my moral system rests on my accepted version of the facts, he who denies my moral judgments or my version of the facts, is to me perverse, alien, dangerous. How shall I account for him? The opponent has always to be explained, and the last explanation that we ever look for is that he sees a different set of facts. Such an explanation we avoid, because it saps the very foundation of our own assurance that we have seen life steadily and seen it whole.
