From Human Nature to Moral Philosophy1

Published online by Cambridge University Press:  01 January 2020

Extract

In recent times the conception of the human being, particularly in Western moral philosophy, has been of an intellectual center, installed in a biological vessel like a “ghost in the machine”—according to Gilbert Ryle's haunting image. To be sure the machine in this image is fashioned of biological matter and governed by biological laws, but it is also subject to the “higher” law of the will, no less than to fundamental laws of physics. It is also the manifest image of the self in Western society outside the academy—the image a person procures by dint of growing up in a distinctive human climate—the image that each of us, in an increasingly wider circle centered on Europe, must master if we are to maneuver successfully in the contemporary legal and social milieu. It makes some sense to invoke such an image for the purposes of certain traditional moral theories. For the image, or something very like it, easily renders talk of individual responsibility sensible.

I want to thank Chrisoula Andreou, Steve Downes, Leslie Francis, Peter Hare, Cynthia Stark, and (as always) Barry Smith for willingness to read early versions of this essay and help me shape the argument. Thanks also to those in attendance at a reading of a version of this paper at the Feminist Moral Philosophy Conference held at the University of Western Ontario. But thanks most of all to Samantha Brennan, who asked me to write this paper and illuminated the way. Without her urging, I should never have learned so much as I did.

5 Philip, Kitcher, Vaulting Ambition (Cambridge, MA: MIT Press, 1985)Google Scholar is a brilliant diagnosis of the work of assumptions in pop sociobiology in its first flush of success.

6 To claim that some trait is an adaptation is not to claim that it is adaptive- or advantageous- for organisms that manifest it today. It is instead to claim that the reason for its continued recurrence lies in an advantage it conferred on individuals who bore it in the past.

13 This is true of the social insects to a very high degree. But it is equally true of primates. See E. O., Wilson, Sociobiology (Cambridge, MA: Harvard University Press, 1975)Google Scholar, cf.

Hrdy supports the contention of Barry Keveme and collaborators, founded upon genetic neurological experiments with mouse brains, to the effect that prolonged association among female relatives was the adaptive environment for social brains and that larger brains, built for social interaction, are passed through the matriline.

14 The evidence for this is discussed at great length in Hrdy, Mother Nature, and in Martin, Daly and Margo, Wilson, Homicide (New York: de Gruyter, 1988).Google Scholar

18 Wilson, by contrast, has a less behavioristic picture of the agent, which he gets from thinking about studies in cognitive and social psychology. He introduces the notion of schema: a schema is a configuration within the brain, innate or learned, against which neural inputs are compared as they come in, with either a “matching” or “not matching” result. The schemas, he writes, contribute to making up a person's mental “set,” screening out or preferring certain features or details in favor of others, filling in missing sensory detail, heightening some decisions or alternatives to the disadvantage of others. And this way lies gestalt psychology. Most significantly of all, schema within the brain could serve as the physical basis of will. An organism can be guided in its actions by a feedback loop: a sequence of messages from the sense organs to the brain schemata back to the sense organs and on around again until the schemata “satisfy” themselves that the correct action has been completed. The mind could be a republic of such schemata, programmed to compete among themselves for control of the decision centers, individually waxing or waning in power in response to the relative urgency of the physiological needs of the body being signaled to the conscious mind through the brain stem and midbrain. Will might be the outcome of the competition, requiring the action of neither a “little man” nor any other external agent. There is no proof that the mind works in just this way. For the moment, suffice it to note that the basic mechanisms do exist; feedback loops, for example, control most of our automatic behavior. It is entirely possible that the will- the soul, if you wish-emerged through the evolution of physiological mechanisms. But, clearly, such mechanisms are far more complex than anything else on earth” (On Human Nature [Cambridge, MA: Harvard University Press, 1978], 76–77).

20 Like Wilson, Kitcher (Vaulting Ambition, ch. 11) also uses the framework of freedom and determinism to treat the subject, but the framework is too restrictive, as I think Kitcher's discussion illustrates.

21 Seminal work on this topic was conducted by Boyd and Richerson, Culture and the Evolutionary Process, and also by Cavalli-Sforza and Feldman, Cultural Transmission and Evolution.

22 Study of human evolution has also made us humans look less honorable even than we took ourselves to be, and certainly less honorable than some other members of the animal kingdom. One of our bigger crimes (among many) is that we humans have practiced routine infanticide, as deliberate and well-timed as you please, not only of our own offspring, but of offspring belonging to our rivals, so as to advance the cause of our own lineage- though we most assuredly did not put it to ourselves in these terms. Chimpanzees do better. The research on this subject was spearheaded by Sarah Blaffer Hrdy; see her Mother Nature.

23 Some folk might prefer the term “socially constructed,” but this term has overtones of an unreality about it, that philosophers should view as distasteful, or at least controversial.

28 Whereas I am naming it ‘behaviorism,’ Kitcher names it ‘determinism.’ Determinism is normally reserved for a doctrine that refers to the past's fixation of the future. And I am observing this practice. But it amounts to the same thing: there is loss of privilege or power that the self enjoys.

41 Buss, “Evolutionary Insights into Feminism and the Battle of the Sexes,” 314. Sarah Blaffer Hrdy is somewhat more skeptical. Her research on the role of parental investment in shaping the human species lead her to this, somewhat contrasting, conclusion: “We are a clever and highly innovative species, but not infinitely so. Our past matters, not just on the physical, but on the emotional front. Does this mean we have no conscious choice over how we lead our lives? Not at all. People exercise free will all the time- but only in those areas where Mother Nature cuts them some slack. A woman can choose which baby she will adopt, but falling in love with that child will not be automatic …. This book will make clear why efforts to legislate a mother's love- by telling a mother with an unwanted pregnancy, for example, that she must carry it to term - are so often destined to end badly” (Mother Nature, 117).
