George Herbert Mead was an American philosopher known for his theory of the social self. He believed that the self develops through social interaction and language. According to Mead, the self has two parts - the "I", which represents impulses and tendencies, and the "Me", which incorporates the attitudes of others through socialization. He saw language and role-taking as central to how individuals construct their identities and engage in social life. Erving Goffman further developed these ideas through his dramaturgical approach, viewing social interaction as performances where people act according to social expectations.
