What concept did Ernest Renan define in relation to continuous community choice?

The concept defined by Ernest Renan in relation to continuous community choice is the idea of the "Daily Plebiscite." Renan articulated this notion in his famous lecture "What is a Nation?" wherein he emphasized that a nation is not just a defined territory or a common ancestry but rather a daily decision made by its members to live together as a united community. This concept reflects the ongoing choice and commitment of individuals to affirm their national identity and the collective will of the people, rather than a one-time historical event or declaration.

Renan's idea highlights the fluid and dynamic nature of national identity, suggesting that belonging to a nation involves constant reaffirmation through shared values, historical experiences, and mutual consent. This perspective challenges more rigid or static definitions of nations based on ethnicity or geography, promoting instead the notion of an active, participatory process by which individuals continuously choose to be part of a larger community.
