"There are in fact two things, science and opinion; the former begets knowledge, the later ignorance"
About this Quote
The line also works as professional self-defense. Early medicine competed with priests, folk healers, and charismatic guessers. By calling opinion a source of ignorance, Hippocrates is delegitimizing rivals who rely on authority, tradition, or vibes. Its an argument for medicine as craft: observation, pattern, cause, and prediction - not story.
The subtext feels startlingly modern because the target isnt merely misinformation; its epistemic overconfidence. Opinion is easy, fast, flattering. It offers identity and belonging. Science is slower and frequently humiliating, forcing you to revise yourself in public. Hippocrates is betting that a culture willing to tolerate that humiliation will get better at staying alive.
Read in context, its less a timeless proverb than a political claim about who gets to speak for reality. In a world where illness could be interpreted as fate or punishment, insisting on science is insisting on agency - and on accountability for being wrong.
