What does heterodoxy mean?
Heterodoxy is a formal word for a belief, opinion, or practice that departs from the accepted doctrine of an established religious, political, philosophical, or cultural system. In older usage, it commonly referred to disagreement with religious orthodoxy, especially teachings or practices judged heretical by an institutional church. In modern contexts, it is broader and may describe political nonconformity, unconventional theory, or a challenge to prevailing professional or social consensus. The term usually has a critical tone: calling something heterodox signals that it departs from an authority, although some groups use the word approvingly to identify their own independent or dissident position. Heterodoxy is therefore more than simple eccentricity; it implies conflict with a recognized standard. It is especially useful when discussing the relationship between innovation and institutional authority, since a heterodox idea may be neglected or opposed precisely because it does not fit the prevailing system. The plural is heterodoxies.
