The document discusses different theories about the nature of self. It notes that sociologist Marcel Mauss believed that one's self is shaped by the culture and society into which they are born. Psychologist Lev Vygotsky viewed human development as socially mediated, with children acquiring values and strategies from more knowledgeable members of society. Sociologist George Herbert Mead's theory was that the self emerges from social interactions, responding to others and internalizing external opinions to develop a sense of self over time through social experiences.
