"Received ideas" refer to the views or opinions that a person or society has accepted without questioning their validity. These beliefs could be cultural, philosophical, religious, or scientific. There are several synonyms for "received ideas," including "prejudice," "convention," "stereotype," "dogma," "tradition," and "orthodoxy." These words imply that the ideas are not necessarily accurate or rational. They may be based on hearsay, propaganda, or outdated information. It's important to question and challenge received ideas to avoid perpetuating harmful myths or biases. Rather than blindly accepting what others believe, we should strive to seek out evidence-based and objective truths.
