Friedrich Nietzsche 
The Case of Wagner [EPUB ebook] 

In reading these two essays we are apt to be deceived, by their virulent and forcible tone, into believing that the whole matter is a mere cover for hidden fire, -a mere blind of æsthetic discussion concealing a deep and implacable personal feud which demands and will have vengeance. In spite of all that has been said to the contrary, many people still hold this view of the two little works before us; and, as the actual facts are not accessible to every one, and rumours are more easily believed than verified, the error of supposing that these pamphlets were dictated by personal animosity, and even by Nietzsche’s envy of Wagner in his glory, seems to be a pretty common one. Another very general error is to suppose that the point at issue here is not one concerning music at all, but concerning religion.
