  Great apes deliberate, plan, and reason, thus displaying rationality and the capacity for intentional action. They exhibit bodily self-awareness, as evidenced through imitations of bodily gestures and their reactions to mirrors. They also exhibit social self-awareness, as evidenced by their knowledge of their position within their group’s social hierarchies. Their social self-awareness also, ipso facto, demonstrates their sociability, which is also implied by the cultural transmission of accumulated knowledge in primate communities. The existence of a limited degree of moral agency is also supported by apparently altruistic actions for which no conditioning or instinctual explanation seems plausible.
