Moral psychology has shaken up moral philosophy in recent years (see, e.g., here and here). The upheaval is welcome. Understanding better how ethical judgements work should eventually lead to positive behaviour change. For example, we might hope for more altruism to solve collective action problems like climate change, and less in-group vs out-group thinking, to curb racism.
So far, however, moral psychology’s impact on ethical conduct has mostly been within the narrow confines of academic journals. The philosophers who took up moral psychological findings mainly focus on rather abstract questions about the theory of knowledge and methodology in ethics. For example, a significant debate concerns the question of whether moral judgments remain warranted given evidence of their psychological origin (see, for example, some of my previous blogs here and here).
Notwithstanding the fascinating nature of such meta-ethical questions, it is a long way from progress in these theoretical debates to effecting positive behavioural change in people. Indeed, moral psychology’s practical impact has not been a focus of much academic work yet.
Our hope may rest on what we can call ‘trickle-down ethics,’ where the revelations of ethicists trickle down to all of society eventually. Moral psychology may impact moral philosophy, and so the impact of moral psychology on moral philosophy may finally be felt in practice, too. However, there is no clear evidence for the success of trickle-down ethics, and blindly trusting it can be frustrating. After all, engaging in moral philosophy is a way to understand what ought to be done, and why, and then to do it – not merely hoping that something eventually gets done. Even if moral philosophy as a discipline has illuminated the ‘understanding’ part, we leave the ‘practice part’ almost entirely to an ill-founded hope in trickle-down ethics. So, blind trust in trickle-down ethics is probably up for a displeasing reality check, especially if the frail prospect of trickle-down economics is any indicator. Read more »


One autumn I’m suddenly taller than my mother. The euphoria of wearing her heels and blouses will, for an instant, distract me from the loss of inhabiting the innocence of a child’s body—the hundred scents and stains of tumbling on grass, the anthills and hot powdery breath of brick-walls climbed, the textures of twigs and nodes of branches and wet doll hair and rubber bands, kite paper and tamarind-candy wrappers, the cicada-like sound of pencil sharpeners, the popping of coca cola bottle caps, of cracking pine nuts in the long winter evenings— will blunt and vanish, one by one.

We are all in some sense equal. Aren’t we? The Declaration of American Independence says that, “We hold these Truths [with a capital ‘T’!] to be self-evident” – number one being “that all Men are created equal.” Immediately, you probably want to amend that. Maybe, not “created”, and surely not only “Men” – and, of course, there’s the painful irony of a group of landed-gentry proclaiming the equality of all men, while also holding (at that point) over 300,000 slaves. But don’t we still believe, all that aside, that all people are, in some sense, equal? Isn’t this a central and orienting principle of our social and political world? What should we say, then, about what equality is for us now?
Einstein had called nationalism ‘an infantile disease, the measles of mankind’. Many contemporary cosmopolitan liberals are similarly skeptical, contemptuous or dismissive, as its current epidemic rages all around the world particularly in the form of right-wing extremist or populist movements. While I understand the liberal attitude, I think it’ll be irresponsible of us to let the illiberals meanwhile hijack the idea of nationalism for their nefarious purpose. Nationalism is too passionate and historically explosive an issue to be left to their tender mercies. It is important to fight the virulent forms of the disease with an appropriate antidote and try to vaccinate as many as possible particularly in the younger generations.



The roof of Notre-Dame de Paris, lost in the fire of April 15, 2019, was nicknamed The Forest because it used to be one. It contained the wood of around 1300 oaks, which would have covered more than 52 acres. They were felled from 1160 to 1170, when they were likely several hundred years old. It has been estimated that there is no similar stand of oak trees anywhere on the planet today.
