Robert LeFevre argues that the drive for ownership is a fundamental human instinct and essential to survival, with property relationships being central to our mastery of the environment. He critiques traditional philosophy for overlooking this vital aspect of human experience, treating property as materialistic rather than intrinsic to human existence. LeFevre mounts a rigorous libertarian defense of self‑ownership and private property, asserting that these rights are foundational and inviolable for both individual and societal well‑being.
