In Liberty and Nature, Rasmussen and Den Uyl use an Aristotelian conce
ption of the human good to provide a foundation for libertarianism. Th
eir principal argument is that intelligence and virtue ave necessary i
ngredients in every flourishing human life, but since these are not go
ods that the state can distribute to individuals, governments can play
only a modest role in promoting the common good. The state best promo
tes the well-being of its citizens by allowing them to pursue happines
s in a manner of their own choosing, and defending them against those
who would invade their moral boundaries.
