 Sullins argues in line with Dennett that moral agency is not restricted to human beings (2006). He proposes that computers systems or, more specifically, robots are moral agents when they have a significant level of autonomy and they can be regarded at an appropriate level of abstraction as exhibiting intentional behavior. A robot, according to Sullins, would be significantly autonomous if it was not under the direct control of other agents in performing its tasks. Note that Sullins interprets autonomy in a narrow sense in comparison to the conception of autonomy in moral philosophy as property of human beings. He adds as a third condition that a robot also has to be in a position of responsibility to be a moral agent. That is, the robot performs some social role that carries with it some responsibilities and in performing this role the robot appears to have ‘beliefs’ about and an understanding of its duties towards other moral agents (p.  28). To illustrate what kind of capabilities are required for “full moral agency”, he draws an analogy with a human nurse. He argues that if a robot was autonomous enough to carry out the same duties as a human nurse and had an understanding of its role and responsibilities in the health care systems, then it would be a “full moral agent”. Sullins maintains that it will be some time before machines with these kinds of capabilities will be available, but “even the modest robots of today can be seen to be moral agents of a sort under certain, but not all, levels of abstraction and are deserving of moral consideration” (p. 29).
