Apropå detta med Glassbilen och kyrkklockor skriver Arthur Schopenhauer följande om oljud i Parerga und Paralipomena (1851), vol. 2, kap. 30, § 378:
The superabundant display of vitality, which takes the form of knocking, hammering, and tumbling things about, has proved a daily torment to me all my life long. There are people, it is true – no, a great many people – who smile at such things, because they are not sensitive to noise; but they are just the very people who are not sensitive to argument, or thought, or poetry, or art, in a word, to any kind of intellectual influence. The reason of it is that the tissue of their brains is of a very rough and coarse quality. On the other hand, noise is a torture to intellectual people.
