legal definition emphasizes its implications for copyright, while Romain Rolland imagines an intellectual public as the ideal audience. Bernays underscores the media's influence in shaping public sentiment, contrasting with Emerson’s focus on genuine conviction in speech. These viewpoints together demonstrate public performance as a dynamic interaction of art, law, and social influence.
