"The mistake of most people is to suppose that it is by the ear they communicate with music, and therefore that they are purely passive to its effects. But this is not so; it is by the reaction of the mind upon the notices of the ear (the matter coming by the senses, the form from the mind) that the pleasure is constructed, and therefore it is that people of equally good ear differ so much in this point from one another."

-Thomas De Quincey’s ‘Confessions of an Opium Eater’
