Erving Goffman was a Canadian sociologist known for his influential work on social interactions and the concept of self-presentation. He explored how people manage their identities in everyday life, often using the metaphor of theater to describe social behavior. His book, The Presentation of Self in Everyday Life, highlights how individuals perform different roles depending on their audience and context. Goffman's ideas have had a lasting impact on sociology and psychology, particularly in understanding stigma and identity. He examined how societal expectations shape personal experiences, emphasizing that our interactions are often influenced by the perceptions of others. His work continues to inspire discussions about social behavior and identity today.
