Skepticism

The discipline of doubt. Not cynicism, but the honest admission that certainty may be beyond us.

Pyrrho pioneered a radical form of skepticism: since we cannot know the true nature of things, we should suspend judgment entirely. The result, he claimed, is not confusion but tranquility. Later skeptics in the Academy (followers of Plato, ironically) continued the tradition. Skepticism was not nihilism; it was a method, a refusal to accept claims without evidence, and it remains the foundation of scientific and philosophical inquiry.
