The ethical history of the friars or the preaching orders mingles with the ethical history of Scholasticism. The ethics of the Schoolmen was a syncretism of two moral systems, the pagan-classical or Aristotelian and the Christian. With the four classical virtues of wisdom, prudence, temperance, and justice were combined the three Christian virtues of faith, hope, and love. But these two moral types, the classical and the theological, each being taken in its entirety, were mutually inconsistent ideals of virtue. The pagan code was a morality based on the autonomy of the individual reason; the Church code was based on an external authority. The one was inner and natural, the other outer and supernatural. The scholastic system was thus an incongruous combination of naturalism and supernaturalism in ethics, of native virtues and “virtues of grace.” This dualism is the essential fact in the history of the ethics of Scholasticism. As it was the great effort of the Schoolmen in the domain of dogma to justify the doctrines of the Church, to show their reasonableness and consistency, so was it their great effort in the domain of ethics to justify the Church’s composite moral ideal, to show all its duties and virtues to form a reasonable and consistent system. The best representative of this effort of reconciliation was the great Schoolman Thomas Aquinas. But a perfect fusion of the diverse elements was impossible. There were ever striving in the system two spirits--the spirit of Greek naturalism and the spirit of Hebrew-Christian supernaturalism.
