We argue on consequentialist grounds for the transfer of Sandai, an orangutan, to an orangutan sanctuary. First, we show that satisfying his interest in being transferred brings far greater value than the value achieved by keeping him confined. Second, we show that he has the capacities sufficient for personhood. Third, we show that all persons have a right to relative liberty insofar as they have interests they can exercise only under conditions of relative liberty. Fourth, we show that individuals need (...) not be able to assume social obligations and duties in order to be rights holders. -/- Our argument reflects commitments, as we say, to consequentialist reasoning about moral problems. However, we note that influential representatives of the other dominant ethical traditions—the deontological and Aristotelian traditions—reach our conclusion, too. It makes no difference, in this instance, which ethical theory one adopts. Under all of them, Sandai is a person with an interest in relative liberty entitled to habeas corpus protection. (shrink)

I argue for the moral relevance of a category of individuals I characterize as far-persons. Following Gary Varner, I distinguish near-persons, animals with a " robust autonoetic consciousness " but lacking an adult human's " biographical sense of self, " from the merely sentient, those animals living "entirely in the present." I note the possibility of a third class. Far-persons lack a biographical sense of self, possess a weak autonoetic consciousness, and are able to travel mentally through time a distance (...) that exceeds the capacities of the merely sentient. Far-persons are conscious of and exercise control over short-term cognitive states, states limited by their temporal duration. The animals in question, human and nonhuman, consciously choose among various strategies available to them to achieve their ends, making them subjects of what I call "lyrical experience:" brief and potentially intense pleasures and pains. But their ends expire minute-by-minute, not stretching beyond, I say metaphorically, the present hour. I conclude by discussing the moral status of far-persons. (shrink)

What is it to be a better ape? This is the question Victor Kumar and Richmond Campbell ask in their book on the evolution of the moral mind, an ambitious story that starts with the common ancestor of the modern apes—humans, chimpanzees, bonobos, gorillas, and orangutans. Of all of us, it’s the humans who remain in the running for being a better ape, because we’re the ones who have all the necessary ingredients: the binding emotions of sympathy and loyalty (...) which we share with our nonhuman cousins, but also the collaborative emotions of trust and respect and the reactive emotions of guilt and resentment. Importantly, only humans are thought to have norms, and to be biologically prepared to learn norms. For Kumar and Campbell, the co-evolution of emotions and norms is what set humans on this path so we can become a better ape. -/- The story they tell is artfully woven from major theories in psychology and anthropology, and those of us who have pre-existing opinions about these theories have points where we can quibble regarding the nature of the emotions–whether only humans imitate, what norms of fairness amount to, or whether any other species are generalists who can survive in a wide range of habitats. Rather than focusing on these, I want to turn to an exciting hypothesis Kumar and Campbell propose about the evolution and function of norms. While it is most common to think that norms helped our ancestors solve the collective action problems that emerged when larger groups of individuals started living together, Kumar and Campbell suggest a different, though complementary, function for norms. They propose that norms provide a more precise and flexible means for coordinating behavior in quickly changing societies. On their view, it isn’t the size of community that is the most significant variable, but rather the speed at which culture evolves. -/- That norms are a human universal is indubitable. Our contemporary human societies are rife with rules constraining our behaviors, governing aspects of our lives from birth to death, prescribing practices about what to wear, how to work, what to eat, when and how to sleep as well as rules about rare practices that are proscribed. However, Kumar and Campbell also presume that norms are human unique. Here I have more than a quibble, given the burgeoning empirical and theoretical literature on the question of animal normativity (Andrews 2020; Danón 2019; Fitzpatrick 2020; de Waal 2014; von Rohr et al. 2011; Rohr et al. 2015; Whiten et al. 2005; Westra et al., in prep)...

Orang-utans played a communication game in two studies testing their ability to produce and comprehend requestive pointing. While the ‘communicator’ could see but not obtain hidden food, the ‘donor’ could release the food to the communicator, but could not see its location for herself. They could coordinate successfully if the communicator pointed to the food, and if the donor comprehended his communicative goal and responded pro-socially. In Study 1, one orang-utan pointed regularly and accurately for peers. However, they responded only (...) rarely. In Study 2, a human experimenter played the communicator’s role in three conditions, testing the apes’ comprehension of points of different heights and different degrees of ostension. There was no effect of condition. However, across conditions one donor performed well individually, and as a group orang-utans’ comprehension performance tended towards significance. We explain this on the grounds that comprehension required inferences that they found difficult – but not impossible. The finding has valuable implications for our thinking about the development of pointing in phylogeny. (shrink)

Self-consciousness is a product of evolution. Few people today disagree with the evolutionary history of humans. But the nature of self-consciousness is still to be explained, and the story of evolution has rarely been used as a framework for studies on consciousness during the 20th century. This last point may be due to the fact that modern study of consciousness came up at a time where dominant philosophical movements were not in favor of evolutionist theories (Cunningham 1996). Research on consciousness (...) based on Phenomenology or on Analytic Philosophy has been mostly taking the characteristics of humans as starting points. Relatively little has been done with bottom-up approaches, using performances of animals as a simpler starting point to understand the generation of consciousness through evolution. But this status may be changing, thanks to new tools coming from recent discoveries in neurology. The discovery of mirror neurons about ten years ago (Gallese et al. 1996, Rizzolatti et al. 1996) has allowed the built up of new conceptual tools for the understanding of intersubjectivity within humans and non human primates (Gallese 2001, Hurley 2005). Studies in these fields are still in progress, with discussions on the level of applicability of this natural intersubjectivity to non human primates (Decety and Chaminade 2003). We think that these subject/conspecific mental relations made possible by mirror neurons can open new paths for the understanding of the nature of self-consciousness via an evolutionist bottom-up approach. We propose here a scenario for the build up of self-consciousness through evolution by a specific analysis of two steps of evolution: first step from simple living elements to non human primates comparable to chimpanzees, and second step from these non human primates to humans. We identify these two steps as representing the evolution from basic animal awareness to body self-awareness, and from body self-awareness to self-consciousness. (we consider that today non human primates are comparable to what were pre-human primates). We position body self-awareness as corresponding to the performance of mirror self recognition as identified with chimpanzees and orangutans (Gallup). We propose to detail and understand the content of this body self-awareness through a specific evolutionist build up process using the performances of mirror neurons and group life. We address the evolutionary step from body self-awareness to self-consciousness by complementing the recently proposed approach where self-consciousness is presented as a by-product of body self-awareness amplification via a positive feedback loop resulting of anxiety limitation (Menant 2004). The scenario introduced here for the build up of self-consciousness through evolution leaves open the question about the nature of phenomenal-consciousness (Block 2002). We plan to address this question later on with the help of the scenario made available here. (shrink)
