Libertarian political theory is built around the idea of individual liberty. One easy way we define individual liberty is by referencing two key ideas:
Self-ownership is the idea that the individual is sovereign over their own body. From self-ownership we understand that we possess autonomy and self-determination as a fundamental human right, with a boundary where other people’s rights begin.
From the understanding of self-ownership, we can begin to ask ourselves what would be ethical choices to make as an autonomous being. The principle of non-aggression is the idea that it is never OK to initiate force or fraud against another human being.
