The American belief in the right to be free as long as another's rights are not harmed is best known as the principle of individual liberty or the harm principle. This concept is central to many democratic societies and emphasizes that individuals have the freedom to act as they wish, provided their actions do not infringe upon the rights and freedoms of others.

This principle is often associated with the philosophy of John Stuart Mill, who articulated that the only justification for restricting individual liberty is to prevent harm to others. In essence, it promotes a balance between personal freedom and social responsibility, underscoring the importance of mutual respect and coexistence in a diverse society. This belief forms the foundation for many laws and social norms that protect individual rights while simultaneously maintaining order and equity within the community.
