 Fifth, virtue cannot be a trait of divine beings, if there are such, since it is the power to overcome obstacles that would not be present in them. This is not to say that to be virtuous is to be the victor in a constant and permanent war with ineradicable evil impulses or temptations. Morality is “duty” for human beings because it is possible (and we recognize that it is possible) for our desires and interests to run counter to its demands. Should all of our desires and interests be trained ever so carefully to comport with what morality actually requires of us, this would not change in the least the fact that morality is still duty for us. For should this come to pass, it would not change the fact that each and every desire and interest could have run contrary to the moral law. And it is the fact that they can conflict with moral law, not the fact that they actually do conflict with it, that makes duty a constraint, and hence is virtue essentially a trait concerned with constraint.
