Doubt

The original meaning of the term skeptic or doubter referred to the process of seeking, searching for the truth. Since there’s always room for doubt, the core principle became the suspension of judgment. Modern skepticism championed by Descartes postulated a demon-like external force filling our minds with false beliefs but also the possibility of finding an absolute truth. The early Greek version doubted this possibility also and described the skeptical search itself as a recipe for happiness, a way of living for the ideal sage. Siting “Chinese whispers” or “the telephone game” and quoting Socrates saying “I only know that I know nothing,” it described all truth as relative to the observer, things are neither one way or another, and recommended avoiding all opinion and belief. Skeptics like Arcesilaus attacked Stoics as proposing a balance between science and opinion which they thought impossible because basically a contradiction in terms.

They merely flirt with doubt.”
