"Knowledge is two-fold, and consists not only in an affirmation of what is true, but in the negation of that which is false"
About this Quote
The subtext is almost moral. “Affirmation” sounds generous, open-handed, progressive; “negation” sounds harsh, even impolite. Colton insists the harsher half is essential. In his formulation, the educated person isn’t simply someone who can recite what’s correct, but someone who can identify, withstand, and discard what’s wrong - including the comforting wrong. That’s an ethic of skepticism aimed as much at the self as at the world: the mind’s job is not to agree, but to discriminate.
Context matters here. Colton wrote in an era when print culture was exploding and public argument was becoming a kind of mass entertainment. More access to ideas didn’t automatically mean better ideas; it meant more noise, more fashionable misconceptions, more plausible-sounding nonsense. His aphorism reads like an early warning about information overload: when claims multiply, the real intelligence lies in subtraction.
It also anticipates a modern tension. Social status often attaches to confident assertion, while careful negation feels negative or pedantic. Colton flips that incentive structure. The smartest move, he implies, may be the unfollowable one: saying no, not yet, that doesn’t hold up.
