Research for my anthrozoology course has included an exploration of primates and personhood:
What is “personhood” in European-American cultures?
Personhood extended to great apes?
Bekoff (1993:104) rightly identifies three types of evidence that can be referenced to support a move to include other great apes as persons: anecdote (what he calls common sense, evidence from observation which can involve use of anthropomorphic terminology- consider Jane Goodall, etc), animal cognition studies that reveal the “richness of the cognitive and intentional lives of great apes”, and evolutionary continuity. Griffin (2001), a central figure in the development of the field of cognitive ethology, provides examples of primate cognition, intentionality and consciousness. Great apes, as social animals living in cooperative groups, developed cognitive capacities and consciousness as it was advantageous for individuals to be able to read the behaviours of others in their social group and act with their interests in mind (with empathy and consideration); this diminished instances of conflict, and cooperation increased all group members’ chances of survival. Griffin introduces the work of primatologists such as Cheney and Seyfarth, whose research has led them to conclude that monkeys (at least those that they have studied, which include baboons and vervets) may have complex social understandings so that they recognise individuals in their troops, their vocalisations and rank, but they do not exhibit empathy or self-awareness. However, Griffin lays down a reasonable challenge to this: “A blanket denial that even monkeys are capable of understanding their own knowledge seems a rather sweeping conclusion to be based on the lack of a kind of evidence that would be very difficult to obtain.” (2001:235-236) The complexity of great ape cognition is also presented by Griffin through examples of captive chimpanzees, bonobos, gorillas and an orang-utan using American sign language or keyboards to communicate with researchers (he particularly reviews the work of Savage-Rambaugh). For Griffin, their abilities reflect evolutionary continuity. Griffin locates these primate examples within his wider understanding that all animals experience subjective conscious awareness (continuity means differences of degree not kind):
“it is both more parsimonious and more plausible to assume that the difference between human and other brains and minds is the content of conscious experience … rather than an absolute all-or-nothing dichotomy between human brains uniquely capable of producing conscious experience, on the one hand, and all other brains that can never do so, on the other, this hypothesis is consistent with our general belief in evolutionary continuity” (2001:18)
De Waal (2010, 2009), in general agreement with Griffin’s conclusions but with focus on primates, builds on the work of Goodall and other researchers who began to fully document similarities between humans and other apes in terms of their emotional lives and behaviours (this is not to say that they did not acknowledge differences); de Waal attempts to provide solid and sound evidence of these shared characteristics, including the origin of morality which he also does not consider to be solely the reserve of human beings.
Noske (1993) has noted the evidence for continuity that primatologists’ have gathered, leading to conclusions that all great apes have complex social lives, in which they respect social rules, read social cues and exhibit abstract thinking. She also argues for the place of the anthropologist in the study of primate societies and cultures; to her, the shift to consider all great apes as persons would also lead to a shift in research procedures, and anthropologists would have much to offer because of existing research practices (participant observation) and focus on understanding the “other”. Noske makes the important point that researchers such as Goodall and Fossey were already doing this in primatology, using what amounted to participant observation methods, which it can be argued should have as much legitimacy when applied to chimpanzees or gorillas as an anthropological participant observation approach used to understand human cultures.
