 Although Aristotle says that voluntary actions are subject to praise and blame, he does not simply identify morally responsible actions with voluntary ones. Small children and animals can engage in voluntary behavior, moving themselves around, using the information they have about their environment, in order to get what they want. What distinguishes adult humans from small children and other animals is our possession of practical reason, which allows us to deliberate about what to do in order to best achieve what we believe to be good and then to make choices on the basis of that deliberation (NE 3.2–4). Only creatures who can make these sorts of deliberative choices are capable of virtue or vice, and only such creatures are accountable for what they do.
