“Detachment is the prerogative of an elite; and as the dandy is the nineteenth century’s surrogate for the aristocrat in matters of culture, so Camp is the modern dandyism. Camp is the answer to the problem: how to be a dandy in the age of mass culture.”
—Susan Sontag (b. 1933)
“Any solution to a problem changes the problem.”
—R.W. (Richard William)
