"All the evolution we know of proceeds from the vague to the definite"
About this Quote
The sentence works because it pairs a scientific-sounding claim with a psychological truth. “Vague” isn’t just ignorance; it’s the real starting condition of inquiry. We begin with hunches, loose categories, imperfect signs. Peirce, a founder of pragmatism and modern semiotics, is telling you that meaning itself evolves this way: a sign starts as a rough pointer, gets tested in use, and hardens into a concept you can rely on. The definite is not discovered intact; it is earned.
Subtext: don’t sneer at ambiguity too quickly. In a culture that prizes hot takes and instant certainty, Peirce treats vagueness as a feature of growth, not a defect. He’s also staking out a metaphysical position against rigid determinism. If the world moves from vague to definite, then novelty is real, chance matters, and the future isn’t merely the past replaying itself with better lighting.
Contextually, this is late-19th-century America absorbing Darwin, industrial acceleration, and the promise (and anxiety) of scientific method. Peirce’s punchline is methodological: knowledge advances by iterating from messy guesses toward clearer commitments, not by pretending clarity was there from the start.
