Justice & Law Quote by Dmitri Mendeleev

"No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments"

About this Quote

Science rarely arrives as a thunderclap; it arrives as a crowd of hunches that refuse to die. Mendeleev is reminding us that even the “laws of nature” we treat like bedrock were first lived as uneasy suspicions: patterns glimpsed at the edge of data, half-articulated in notebooks, argued over in lecture halls, smuggled into conversation as “what if.” The line deflates the mythology of the lone genius who discovers truth in a single, cinematic moment. Recognition, he insists, has a prehistory.

The word “presentiments” does the real work. It’s not evidence yet, not proof, but it’s not mere fantasy either. It names that liminal stage where the mind is already reorganizing reality before the instruments can fully justify it. Coming from the architect of the periodic table - a framework he famously used to predict undiscovered elements and their properties - this is also a quiet defense of scientific imagination. His table wasn’t just cataloging; it was a wager that order existed and could be extended beyond what was currently known.

Subtextually, Mendeleev is making a cultural argument about how knowledge is made: socially, incrementally, and with more intuition than we like to admit. “Established all at once” is the straw man he’s puncturing - a warning against treating consensus as instantaneous or inevitable. The context is 19th-century chemistry trying to become a mature science, shifting from alchemy’s residue and ad hoc classifications to systems with predictive power. Progress, in his telling, is less revelation than accumulation: many near-misses that finally line up.
