"Science is the father of knowledge, but opinion breeds ignorance"
About this Quote
Placed in Hippocrates’ world, the jab lands with extra force. Greek medicine was still elbowing aside divine causation, folk remedies, and philosophical speculation. The Hippocratic turn was to treat illness as a natural phenomenon with patterns you could watch, record, and learn from. So the quote carries professional agenda as much as wisdom: it’s a credentialing move. Trust the physician who measures and compares, not the one who performs certainty.
The subtext is also political, in a small-p sense. Opinion isn’t neutral here; it’s social currency. It spreads fast, flatters the speaker, and demands no accountability. By calling it a breeder of ignorance, Hippocrates anticipates a problem that never stops being modern: when belief outruns evidence, communities don’t just stay wrong - they get organized around being wrong.
Even the gendered metaphor matters. “Father” implies lineage, discipline, inheritance. Science is framed as a tradition you enter and are judged by, not a vibe you adopt.
