Which theory asserts that there are universally accepted principles of human behavior applicable to all individuals?

The theory that asserts there are universally accepted principles of human behavior applicable to all individuals is Natural Law. This philosophical concept posits that certain rights and moral values are inherent to human beings and discoverable through reason, rather than being contingent upon legislation or social norms. Natural Law holds that these principles are universally applicable, meaning they should be recognized and upheld across all societies and cultures.

In contrast, Legal Paternalism focuses on the justification for restricting individual freedoms for their own well-being, rather than asserting universally accepted moral principles. Legal Realism emphasizes the importance of the actual practices and decisions of the courts, suggesting that law is not just a set of written rules but can also be influenced by social, economic, and contextual factors. Legal Positivism asserts that law is based on social facts and is separate from morality, meaning that its applicability does not necessarily rely on universal moral standards. Thus, while these theories contribute significantly to legal philosophy, it is Natural Law that directly connects to universally accepted human behavioral principles.
