It was the classical liberal F. A. Hayek in "Freedom, Reason and Tradition" who most systematically and relentlessly pursued the nature of a libertarian/traditionalist synthesis but was loath to give it a label. He began by distinguishing between two views of human reason, a speculative/rationalistic/utopian and an empirical/evolutionary/institutional one, which was "particularly conspicuous" in their different assumptions about human nature. The former viewed intelligence and goodness as natural to individual man while the latter argued that institutions must be created so that "bad people could do least harm." While not arguing for this on religious grounds, he acknowledged his empirical position was "closer to the Christian tradition of the fallibility and sinfulness of man, while the perfectionism of the rationalist is in irreconcilable conflict with it".
