[...] To abridge thinking in the name of the emergencies that today are permanent reduces it to slogans, perpetual cheerleading or nay-saying. The notion that liberals cannot criticize liberalism or leftists cannot criticize leftism partakes of a bankrupt tradition.

To understand what renders diversity ideological is to understand what devitalizes it—an endeavor that seeks to realize, not junk it.
