What’s the difference between the humanities and economics? Stories. When economists pretends to solve problems in ethics, culture, and social values in purely economic terms, they are “spoofing” other disciplines—that is, impersonating someone else’s email name and address to deceive the recipient. Gary Becker and Freakonomics are good examples of this “imperialism.” But economists shouldn’t spoof anyone, instead they need a “humanomics” which allows the discipline to keep its own qualities. There’s no way to grasp most of what people do by deductive logic—we need stories. Novels are a distinct way of knowing. Ethics requires good judgment and cannot be reduced to theories, models, or sets of rules alone. Economics can’t deal with culture since culture can’t be mathematized. Wisdom also cannot be quantified, nor culture. Economic rationality and efficiency is certainly part of human nature, but by no means all of it. For the rest, we need the humanities. The authors use literature to point out that no one in their right mind ever thought people are rational to begin with. Behavioral economics suffers from the same defect, since you don’t need stories to understand their models. There’s no place for surprise in rational choice economics, nor behavioral economics. And humans constantly surprise—we are the ultimate scamps. Behavioral economics takes no more account of culture than rationalists, and it leaps directly to evolutionary psychology or neurobiology. So many insights from these fields leads a humanist to say, “You mean, you had to prove that?” This is how I feel with Dan Ariely’s study of honesty and religion. Or this: A man sees a cashmere sweater he’d like but thinks too expensive. His wife buys it for him for Xmas, and he’s delighted by the gift, even though the couple pool all of their financial assets. Is this irrational? Richard Thaler says yes, a humanist understands the difference a gift makes (it’s why economists think so many gifts cause a “deadweight loss.” It’s funny, possibly true, but why then do we continue to give gifts?
Behavioral economists should subscribe to the [Milton] Friedman rule: do not claim to be describing real people, but rather your models should be judged on the quality of their predictions. But they claim to understand the psychology of humans and hence have gone further from, not closer to, a humanist perspective.
Dostoevsky wrote: [If someone would] “some day…truly discover a formula for all our desires and caprices,” there would be no caprices at all. “There will be no more incidents and adventures in the world.”
Deidre McCloskey’s work is praised, along with the great novelists, who the authors write “understand people better than any social scientist who has ever lived.” Rather than fuse the humanities and economics, we need a dialogue between them. To understand human society and behavior, we need more than biology, and saying that does not diminish biology. Same with economics. Brain scans sound more scientific without adding any real information. Is there a “science of child rearing”?
I particularly enjoyed the metaphor from Isaiah Berlin’s The Hedgehog and the Fox: An Essay on Tolstoy’s View of History. “The fox knows many things, but the hedgehog knows one big thing.” Which are you? Plato and Gary Becker were hedgehogs, Aristotle and Tolstoy foxes, when it comes to understanding human nature. Hegel, Marx, Lenin, Freud, Jeremy Bentham, Einstein, Jared Diamond (geography is mostly responsible for differences in economic development), Paul Ehrlich—all hedgehogs. Montaigne, Shakespeare, David Hume, Adam Smith, Darwin—all foxes. Hedgehogs are subject to hubris, while foxes can sometimes be too tentative. Hedgehogs provide answers, foxes ask deeper questions. Literature by its very nature is foxy. But hedgehogs breed disciples and movements. The authors: “By their very nature, hedgehogs lack the humility necessary to prevent mistakes from becoming catastrophes.”
Great old adage: “Research is to teaching as sin is to confession. If you aren’t actively engaged in the former, you eventually run out of things to say in the latter.”
“Beware the man of only one book.” Latin proverb
There’s a good discussion on the market for organs (and cloning), and economists do need to consider why so many other smart people feel so strongly to the contrary. I don’t have the answer to this—I tend to support a market for organs—but I understand the arguments on both sides. It’s very similar to the abortion debate, and I know there’s no solution, only tradeoffs. Whatever the answer, it takes more than economics to arrive at it, the authors conclude. Agree.
The realist novelists understood ethics as well, deploying “casuistry,” reasoning by specific cases. The word is now a pejorative, but instead of reasoning down from theories, casuistry reasons up from particulars, and novels are an effective way to do this, with a specific character. If ethics was mere deductive reasoning we could program robots with the principles and rules. But an ethical decision left to a machine is not an ethical decision at all—humans must take responsibility for their decisions—we must “sign it.”
It’s also easier to empathize reading novels, since you can put yourself into the characters, identify with them, their inner thoughts, actions, etc. We don’t just see their external selves, but their inner selves, we are on intimate terms with them. Empathy can be abused as well, it’s why con men are effective. The humanities teach us there’s more to the world than ourselves. Literature liberates us from the prison of self, of our culture, and of our historical period—teaches us to be humble about our own knowledge.
At the end of the day, as Aristotle believed, we need judgment, wisdom, and experience to understand our fellow humans. The humanities are about humans, and that’s why there’s so much to learn from them. If you want knowledge, read nonfiction. If you want wisdom, read great literature.
This is a wonderful book, and you will think your way all the way through it, and possibly even alter some of your views on just how complex—and delightful—humans truly are, beyond the understanding of economic models.
