Is common opinion a dangerous illusion or the foundation of all knowledge?

In short: In Ancient Greece, the concept of doxa represented the shifting sands of public belief. While some philosophers dismissed it as a deceptive shadow of the truth, others saw it as the essential starting point for all rational inquiry and the very bedrock of social order.

The Greek term doxa, derived from dokein ('to appear' or 'to seem'), traditionally stands in opposition to episteme, or certain knowledge. Plato viewed doxa with deep suspicion. In his dialogue Gorgias, he portrayed the Sophists as manipulators who used the malleable opinions of the masses to ensnare others. For Plato, doxa resided in the unreasoning, lower parts of the soul, representing a realm of error and illusion far removed from the true forms of reality.

However, this dismissal was not universal. Aristotle, Plato's student, offered a more practical perspective. He argued that doxa possesses significant value in the physical world and serves as the first step toward achieving episteme. Aristotle introduced the concept of endoxa—beliefs that have been 'tested' through rigorous argumentative struggle within the polis. These stable, accepted truths, passed down through generations, provided a rational basis for belief and practical application.

The meaning of doxy has also expanded through religious and sociological lenses. Between the 3rd and 1st centuries BC, the Septuagint used doxa to translate the Hebrew word for 'glory' (kavod), a usage that permeated the New Testament and continues in Greek Orthodox worship. In the 20th century, sociologist Pierre Bourdieu redefined doxa as the 'taken-for-granted' truths of a society. Unlike open opinion, which can be contested, Bourdieu's doxa is the unquestioned result of socialization, shaping the very structures of social order and common action.
