This Ain't No Mecca, Man -- This Place Is Fucked!

From The Unbearable Lightness of Being:

Behind all the European faiths, religious and political, we find the first chapter of Genesis, which tells us that the world was created properly, that human existence is good, and that we are therefore entitled to multiply. Let us call this basic faith a categorical agreement with being.

The fact that until recently the word "shit" appeared in print as s--- has nothing to do with moral considerations. You can't claim that shit is immoral, after all! The objection to shit is a metaphysical one. The daily defecation session is daily proof of the unacceptability of Creation. Either/or: either shit is acceptable (in which case don't lock yourself in the bathroom!) or we are created in an unacceptable manner.

It follows, then, that the aesthetic ideal of the categorical agreement with being is a world in which shit is denied and everyone acts as though it did not exist. This aesthetic ideal is called kitsch.
