The document explores the concept of 'person' in legal, philosophical, and anthropological contexts, distinguishing between natural persons (human beings) and legal persons (entities like corporations). It discusses various theories that underline the nature of legal personality, including fiction theory, realist theory, concession theory, purpose theory, and bracket theory, as well as Kelsen's theory, ultimately concluding that legal personality is a complex legal construct that grants rights and duties to both living individuals and groups. The text emphasizes the importance of legal personality for institutions, allowing them to engage in legal relationships independently of their members.
