"A man's conscience and his judgment is the same thing; and as the judgment, so also the conscience, may be erroneous"
About this Quote
The intent is political as much as philosophical. Hobbes lived through England’s civil wars, when competing factions killed and governed in the name of conscience. If everyone treats their inner certainty as a trump card against law, you don’t get freedom; you get a moral arms race. His subtext: the loudest appeal to conscience often masks something less noble - factional loyalty, fear, self-justification - and its very sincerity makes it more dangerous. An “erroneous” conscience doesn’t feel erroneous from the inside.
Rhetorically, the line works because it sounds almost tautological, then detonates. “Conscience and judgment is the same thing” is a demystifying equation; the follow-up clause turns that equation into a warning label. Hobbes isn’t arguing that morality is fake, but that moral certainty is not self-authenticating. The broader context is his case for a stable sovereign authority: if private conscience can be mistaken, then public order can’t be built on competing private revelations. The modern sting is obvious: righteous certainty isn’t evidence; it’s a liability that needs checks, institutions, and humility.
