 Individually-based accounts generally take cognitively normal adult human beings as their paradigm and pick out one or more of their attributes as sufficient for the moral status they  enjoy.[4]  These accounts identify overlapping clusters of psychological and cognitive attributes—self-consciousness, awareness of and concern for oneself as a temporally-extended subject; practical rationality, rational agency, or autonomy; moral responsibility; a capacity to recognize other selves and to be motivated to justify one’s actions to them; the capacity to be held, and hold others, morally accountable. These attributes pick out different subsets of human beings. Some self-conscious humans, for example, may lack the capacity to be held morally accountable. But individually-based accounts may differ less in the range of beings to whom they accord full moral status than in the ways they regard those attributes as grounding that status.
