"Our knowledge can only be finite, while our ignorance must necessarily be infinite"
About this Quote
The intent is disciplinary. Popper is policing the border between science and ideology, warning that certainty is often a costume for dogma. In his philosophy of falsification, progress doesnt come from piling up confirmations; it comes from staging ideas against reality and letting the weak ones break. That method requires a temperament: modest about what you have nailed down, aggressive about hunting what you havent. The quote smuggles in that ethic. If ignorance is infinite, then being wrong is not a scandal but a baseline risk; the scandal is refusing to design your thinking to catch errors early.
Context matters: Popper writes in the shadow of totalizing systems Marxism, historicism, fascism that claimed to read history like a script. Against that, he offers an anti-prophetic politics of knowledge. The subtext is almost civic: societies stay open when they treat every doctrine as provisional, every institution as corrigible, every expert as fallible. Infinity here isnt romantic; its a safeguard against the seductions of final answers.
