Let us continue our in-depths discussion of Julian Baggini’s The Edge of Reason, a book that aims, in a sense, at striking a balance between the Scylla of scientistic rationalism and the Charybdis of anti-rational relativism. Chapter 5 concerns what Julian calls “the challenge of psychology,” the idea that since much of our thinking is unconscious, we are not really rational beings, as much as rationalizing ones.
The chapter begins with a short introduction to the famous trolley dilemma, introduced by philosopher Philippa Foot as a tool to bring out our moral intuitions. I will not summarize the thought experiment, since it is well known. Baggini says that it is obvious that when many people “go consequentialist” in one version of the dilemma, and “Kantian” in another, this is because different psychological intuitions, not any explicit moral reasoning, are at play. Which immediately brings him to Daniel Kahneman’s famous distinction between “System 1” and “System 2” reasoning: the version of the dilemma that involves a more personal interaction with others is likely to trigger our emotional responses (System 1), while the impersonal version activates our thinking in terms of large numbers and consequences (System 2).
The problem, of course, is that it may be difficult, philosophically speaking, to make sense of one’s diverging reactions to the different situations posed by the trolley dilemma: “if asked why we should not push the person, we don’t say, ‘I don’t know, it just feels wrong.’ Rather, we come up with various rational justifications, such as the idea that it is wrong to use a person as a means to an end — even when this is just what we were prepared to do in the lever case.”
Kahneman himself seems pretty pessimistic about the sort of inference about human reasoning that we should make from his research: “when asked if his 45 years of study had changed the way that he makes decisions, [Kahneman] had to reply, ‘They haven’t really, very little, because System 1, the intuitive system, the fast thinking, is really quite immune to change. Most of us just go to our graves with the same perceptual system we were born with.’”
Setting aside that even the interviewer had a hard time taking Kahneman’s words at face value, Baggini says “not so fast,” so to speak. He points out that System 1 is an “enemy of reason” only if we conceptualize reason as identical to formal logic, which he has been at pains to argue, in the previous five chapters, is far too narrow a conception.
Julian maintains that the sort of “gut feelings” we sometimes have, especially, but not only, when it comes to moral situations, are in fact the result of quick heuristics embedded into System 1: “Heuristics are cognitive shortcuts, and the key is that they wouldn’t have evolved if they didn’t work more often than not. The problem is that they are so deep rooted that we often find ourselves using them even when we don’t need a quick, snappy solution but cool, calm reasoning.”
Julian seems to hint, in the passage above, that these System 1-based heuristics are the result of biologically rooted instincts, and surely in part that is the case. But I don’t see why they cannot also be the outcome of accumulated experiences, and more likely a deeply intertwined combination of both.
Baggini goes on to suggest that it isn’t at all obvious — as utilitarians, or Kantian deontologists, would argue — that moral questions ought to be analyzed solely on the basis of “cold” (i.e., impartial) reason. The most obvious case, he maintains, is that of parental love. As parents we are partial to our children, and given a choice between intervening on behalf of our child or on behalf of a stranger’s child, we do not hesitate and choose the former. And rightly so, says Julian, as the world wouldn’t likely be a better place if everyone treated their kids as random members of the population. That, of course, generates a tension between “local” ethics (i.e., our personal moral decisions) and “universal” ethics (what we should do when we think of humanity at large). Welcome to the human condition, where sound judgment (which, remember, for Baggini is what defines reason in the broadest terms) is a necessary component of our existence. And where Systems 1 and 2 constantly interplay.
Julian then moves to the perilous territory of “gendered” reason: what if it turns out that people of different genders think in significantly, if not radically, different ways, ways that are deeply rooted in their gender identity? Should we then not talk about reason(s), in the plural, instead of the singular term, and concept, we inherited from the Enlightenment?
He reports a strange conversation he had with the French philosopher Luce Irigaray, who has been influenced by the Lacanian school of psychotherapy, and who thinks of gender differences in a somewhat radical fashion: “When I interviewed her, I suggested that [her position] means that in a sense I was not meeting her at all, since we could not share the same understanding. She agreed. ‘In this moment we seem to be in the same place, inhabiting the same space, the same time, the same country, the same culture, the same language. In a way it is only an illusion.’”
Julian labels this an “extreme” position, “frankly not supported by the best evidence of psychology.” I’m slightly more blunt: it’s nonsense on stilts.
He elaborates along lines that seem eminently sound to me: “Feminist philosophy, for instance, is not separate from all other philosophy. A feminist critique of epistemology (theory of knowledge) has its force because it suggests there is something epistemology is missing because of distortions rooted in gender, distortions it seeks to remedy. Such a critique would lack any power if it amounted to the claim that there is male epistemology and female epistemology, and each of the two should mind their own business.” Exactly, though the latter is, indeed, the position of some radical feminists and gender studies scholars.
Baggini goes on to analyze the gender gap within the philosophical profession, ascribing it to the intellectual culture within, in terms of the assumption that discussions have to be value-neutral (while feminism, most obviously, isn’t), and especially that academic philosophy is characterized by the encouragement of a confrontational approach toward colleagues, which makes a number of women feel very uncomfortable.
All of this certainly does play a role (and indeed, I’ve seen it with my own eyes), but I would like to remind people that a comparable gender gap exists within plenty of other fields where there is no such (special) culture of confrontation, and where there are no approaches to technical matters that depart from value neutrality: mathematics, chemistry, physics and engineering come to mind. So I dispute the idea that the gender gap in philosophy is peculiar to the field, or that the profession itself should undergo some kind of radical change in order to resolve the problem. The problem is going to be resolved in the same way in which it is being addressed in other fields: by encouraging young girls to embrace areas that have been seen as traditionally “male,” on the simple ground that there is no reason at all why they shouldn’t succeed in them. And of course by an explicitly fair treatment of women undergraduate and graduate students, as well as faculty at different ranks. Something, incidentally, that philosophy as a profession is very aware of and has been implementing for years through the efforts of the American Philosophical Association.
So what does psychology tell us about human reason? Baggini suggests a revision of Plato’s famous analogy between the human mind and a chariot led by two horses: “we would do better not to think of the human soul as comprising two wildly different horses and a controlling charioteer, but as being one single equine which draws on all sorts of cognitive tools, from the conscious, systemic and deliberative to the automatic, unconscious and affective.” It’s more a mule than a thoroughbred, he says. The image may be less ennobling, but it is “better to be a many-skilled mule than one-trick pony.”
