The aim of this essay is to argue for the following claims: evil is prevalent; its prevalence is mainly the result of habitual and predictable patterns of action; these actions follow from the vices of their agents; in many cases, neither the evil actions nor the vices from which they follow are autonomous; it is nevertheless justified to hold the agents who perform these actions morally responsible for them; the widespread denial of this claim rests on the principle “ought implies can”; two versions of this principle must be distinguished; neither version can be used to exempt agents from moral responsibility for their nonautonomous actions and vices; this has fundamental implications for how morality and responsibility should be conceived.

In this essay I wish to consider the implications for theory and practice of the following two propositions, either or both of which may be controversial, but which will here be assumed for the sake of argument:

(L) Libertarianism is the correct framework for political morality.

(M) The vast majority of our fellow citizens disbelieve (L).1

Philosophers have recently revived the study of the ancient Greek topics of virtue and the virtues—justice, honesty, temperance, friendship, courage, and so on as qualities of mind and character belonging to individual people. But one issue at the center of Greek moral theory seems to have dropped out of consideration. This is the question of the unity of virtue, the unity of the virtues. Must anyone who has one of these qualities have others of them as well, indeed all of them—all the ones that really do deserve to be counted as virtues? Even further, is there really no set of distinct and separate virtuous qualities at all, but at bottom only a single one—so that the person who has this single condition of “virtue” (and only he) is entitled also to the further descriptions “honest” and “well-controlled” and “just” and “friendly” and “courageous” and “fostering” and “supportive,” and so on, as distinguishable aspects or immediate effects of his unitary “virtue”?

In this essay, I identify the reasons that libertarian principles have failed to capture the popular imagination as an acceptable form of civil society. By the term “libertarian” I mean a belief in and commitment to a set of methods and policies that have as their common aim greater freedom under law for individuals. The term “freedom” in this context means not only a commitment to civil liberties, such as freedom of expression, but also to economic liberties, including a commitment to a laissez-faire policy of free enterprise and free trade between countries. Libertarians, therefore, are committed to the absolute minimum state intervention in the economy as well as in people's private lives. In a world constrained by these libertarian principles, people should be permitted to do as they please, constrained only by rules that prevent them from encroaching on the liberty of others.

Imitation is said to be the sincerest form of flattery. Socially, the proposition may well be true. But in the world of ideas it is false: to the extent that two incompatible traditions use the same words or symbols to articulate different visions of legal or social organization, imitation begets confusion, not enlightenment. The effects of that confusion, moreover, are not confined to the world of ideas, but spill over into the world of politics and public affairs. Words are more than tools of description: they work also as tools of persuasion and transformation. Let a term have a favorable connotation in one context, and its imitative use can mislead people into thinking that a major departure from established practice is merely the extension or updating of an old principle to deal with new circumstances.

Anthony Ashley Cooper (1671–1713), the Third Earl of Shaftesbury, was the grandson of the First Earl of Shaftesbury (also Anthony Ashley Cooper, 1621–1683). The First Earl, along with John Locke, was a leader and founder of the Whig movement in Britain. Locke was the First Earl's secretary and also the tutor of the Third Earl. Both the First and Third Earls were members of parliament and supporters of Whig causes. Although both the First and Third Earls were involved in politics, the Third Earl is better known for intellectual pursuits. Indeed, the Third Earl (henceforth simply “Shaftesbury”) is second only to Locke in terms of influence during the eighteenth century. Yet if one takes into account effects upon literature, the arts, and manners, as well as upon philosophical trends and theories, Shaftesbury might be even more influential. Even if we restrict ourselves to philosophy, Shaftesbury's ideas were admired by thinkers as different as Leibniz and Montesquieu—something which could obviously not be said about Locke. Within ethics, Shaftesbury influenced Francis Hutcheson, David Hume, Samuel Butler, and Adam Smith and is credited with founding the “moral sense” school of thought.
