Certain Quote by Karl Popper
“The old scientific ideal of episteme - of absolutely certain, demonstrable knowledge - has proved to be an idol. The demand for scientific objectivity makes it inevitable that every scientific statement must remain tentative for ever.”
About This Quote
Source Book: Conjectures and Refutations, 1963
Scientific knowledge is provisional; claims of absolute certainty become idols that hinder progress, so all statements must stay open to revision.
In simple terms: Science is always tentative, never final.
Embrace uncertainty and keep questioning.
