A unique feature of the Objectivist virtues is their complete interdependence. To be virtuous, according to Ayn Rand, requires adherence to all aspects of the primary virtue, rationality. This course examines, in theory and in practice, how each of the virtues requires and supports all the others. It shows how Ayn Rand's revolutionary approach offers Man, for the first time, a comprehensive, graspable, and non-contradictory method by which to choose his actions. It also contrasts Objectivism with other ethical systems that not only violate the principle of unity but actually require inconsistency—and immorality—on the part of their adherents.
