On Certainty

work by Wittgenstein
Also known as: “Über Gewissheit”

Quick Summary

Ludwig Wittgenstein's work On Certainty explores the complex relationship between knowledge and certainty, positing that they are distinct concepts and neither necessarily entails the other. Wittgenstein argued that certainty is not about apprehension or "seeing," but rather about a form of acting. A proposition is considered certain when its truth, and the truth of related propositions, is a presupposition within a community's social activities. This means that the foundation of our language games lies in our actions, not in immediately evident truths. The work challenges the idea that certainty is solely based on immediate, self-evident truths, suggesting instead that it is embedded in the practical, everyday use of language and the shared activities of a community.12
