Reposted from way back in 2010:
Criticism as I understand it differs entirely from attack or complaint. Its difference from complaint is especially important here, for I am persuaded that complaints against the machinations of culture today have become as poisonous as the things complained of. This is not surprising. Resentment and indignation are feelings dangerous to the possesor and to be sparingly used. They give comfort too cheaply; they rot judgment, and by encouraging passivity they come to require that evil continue for the the sake of the grievance to be enjoyed.
