11. THE STRETCHING OF MORAL CONCEPTS.--The instances given suffice to show that the moralists speak with a variety of tongues. The code of one age is apt to seem strange and foreign to the men of another. Even where there is apparent agreement, a closer scrutiny often reveals that it has been attained by a process of stretching conceptions. Take for example the so-called "cardinal" virtues [Footnote: From _cardo_, a hinge. These virtues were supposed to be fundamental. The name given to them was first used by AMBROSE in the fourth century A.D. See SIDGWICK, _History of Ethics_, chap, ii, p. 44.] dwelt upon by Plato. The Stoics, who made use of his list, changed its spirit. Cicero stretches justice so as to make it cover a watery benevolence. St. Augustine finds the cardinal virtues to be different aspects of Love to God. The great scholastic philosopher of the thirteenth century, St. Thomas, places in the first rank the Christian graces of Faith, Hope and Charity, but still finds it convenient to use the Platonic scheme in ordering a list of the self- regarding virtues taken from Aristotle. Thus may the pillars of a pagan temple be utilized as structural units in, or embellishments of, a Christian church. Our own age reveals the same tendency. Thomas Hill Green, the Oxford professor, follows Plato. But with him we find wisdom stretched to cover artistic creation; we see that courage and temperance have taken on new faces; and justice appears to be able to gather under its wings both benevolence and veracity. [Footnote: _Prolegomena to Ethics_, Book III, chapter iii, and Book IV, chapter v.] A still wider divergence from the original understanding of the cardinal virtues is that of Dewey, who conceives of them as "traits essential to all morality." He treats, under temperance, of purity and reverence; he makes courage synonymous with persistent vigor; he extends justice so as to include love and sympathy; he transforms wisdom into conscientiousness. [Footnote: DEWEY AND TUFTS, _Ethics_, pp. 404-423.] This variation in the content of moral concepts may be illustrated from any quarter in the field of ethics. Cicero's circumspect "benevolence" advances the doctrine that "whatever one can give without suffering loss should be given even to an entire stranger." Among such obligations he reckons: to prohibit no one from drinking at a stream of running water; to permit anyone who wishes to light fire from fire; to give faithful advice to one who is in doubt; which things, as he naively remarks, "are useful to the receiver and do no harm to the giver." [Footnote: De Officiis, Book I, chapter xvi.]
