Skepticism (n.) is warranted when you can't even see the path to understanding: there is a known road into quantum electrodynamics, but none into a page of literary theory.
Skepticism (n.) toward the dissident is reasonable: a three-volume, footnoted proof that the world is flat should make anyone cautious, and that is how dissent sounds to most people.
Skepticism (n.) is mere sanity when leaders who mobilized for war on one ground now announce it was for another.
Skepticism (n.) about charges against your own country is simply expected; skepticism about charges against an official enemy is an unforgivable crime.
Skepticism (n.) toward officials gets called vengefulness, when it may only be realism learned from their earlier false assurances.
Skepticism (n.) in the press is rationed: it scolds itself over a lack of it toward a campus story while swallowing government accounts of an air war.
