Is morality rational? In this book Gauthier argues that moral principles are principles of rational choice. He proposes a principle whereby choice is made on an agreed basis of cooperation, rather than according to what would give an individual the greatest expectation of value. He shows that such a principle not only ensures mutual benefit and fairness, thus satisfying the standards of morality, but also that each person may actually expect greater utility by adhering to morality, even though the choice (...) did not have that end primarily in view. In resolving what may appear to be a paradox, the author establishes morals on the firm foundation of reason. Gauthier's argument includes an account of value, linking it to preference and utility; a discussion of the curcumstances in which morality is unnecessary; and an application of morals by agreement to relations between peoples at different levels of development and different generations. Finally, he reflects on the assumptions about individuality and community made by his account of rationality and morality. (shrink)

Although Hobbes talks about the laws of nature as prescribing the virtues, it is easier to think of them as proscribing the vices. The nine vices that are proscribed by the laws of nature are injustice, ingratitude, greed or inhumanity, vindictiveness , cruelty, incivility or contumely, pride, arrogance, and unfairness . The corresponding virtues that are prescribed by the laws of nature are justice, gratitude, humanity or complaisance, mercy, , civility, humility, , modesty, and equity. The difficulty of coming up (...) with names for some of the virtues, and even for some of the vices, shows that they are not all among the most common moral virtues and vices. Nonetheless, as described by Hobbes, they are genuine moral virtues and vices, traits of character such that all impartial rational persons would favor everyone having the virtues and no one having the vices. All of these virtues are such that they benefit everyone impartially by promoting peace, and are not primarily of benefit to the person having them. This is what makes them moral virtues and distinguishes them from the personal virtues of courage, prudence, and temperance. The laws of nature are the dictates "of right reason, conversant about those things which are either to be done or omitted for the constant preservation of life and members, as much as in us lies." But the law of nature "dictating peace, for a means of the conservation of men in multitudes;" is also the moral law because "in the means to peace, [it] commands also good manners, or the practice of virtue; and therefore it is called moral." Hobbes correctly sees both that peace benefits all persons impartially and that impartiality is essential to morality. His account of the moral virtues correctly makes them traits of character that would be favored by all impartial persons. His argument for the rationality of these moral virtues is that one's self-interest, which for Hobbes is primarily one's long-term preservation, is enhanced by having these virtues. There is no incompatibility between morality and self-interest as long as what is in one's own self-interest is equally in the interest of everyone else. Hobbes sees this point quite clearly and it is at the heart of his justification of the moral virtues. (shrink)
