Abstract
By ‘moral liberty’ Reid means, not freedom to act, but freedom to choose, or to decide. And the choosing he is talking of is an internal something, not the external performance that choosing often is, where it is the executing of one of a number of options—as in the response to “Choose any card from this deck.” Non-human animals sometimes act voluntarily, but those actions “seem to be invariably determined by the passion, or appetite, or affection, or habit, which is strongest at the time.” A voluntary action is for Reid a willed action, i.e., an action done with an object. Even if some animals sometimes perform such actions, they have no power to determine their own wills, no “power of self-government.” Moral liberty is the liberty of a moral agent, his power over the determinations of his will, which requires “not only a conception of what he wills, but some degree of practical judgment or reason.” Moral liberty, then, is “the Liberty of Moral Agents, who are capable of acting well or ill, wisely or foolishly.” Unless we are in that sense free, nothing that we do can be the proper object of blame or approval.
