The debate between agency and structure revolves around the relationship between an individual's free will and societal structures. Sociologists have proposed various theories, including Pierre Bordeaux's concept of 'habitus', Berger and Luckmann's social construction of reality, and Anthony Giddens' structuration theory. The discussion highlights the complexity of this debate, with some arguing that society shapes individual personalities and habits, while others believe that individuals are autonomous agents who collectively shape society.
