 If ethics is the branch of philosophy concerned with practice, then in a sense all of Rand’s philosophy is ethics, for Rand stresses “the supremacy of actual living over all other considerations”, and insists that philosophy needs to be “brought up to the realm of actual living”—adding “I say intentionally brought up to it, not down” (Journal entry for 15 May 1934, p. 72; in Rand 1997: 73). Consequently, Rand regularly concerns herself with the practical implications and social relevance not only of moral and political philosophy, but likewise of the seemingly more arcane strata of metaphysics and epistemology—as when she identifies errors in concept-formation as one of the roots of racism, or mind-body dualism as a root of the dichotomy between economic and personal freedom. This approach likewise reflects Rand’s emphasis on integrating each piece of information into the total context of one’s knowledge, and her consequent hostility to compartmentalization.
