The Nature of Morality: A Thesis Primer

Below is a short preface to my thesis on evolution and moral ecology that gives the broad brush outline of my argument and how it’ll likely flow from chapter to chapter. Much is in flux, even at this stage (when is it supposed to settle down, I wonder), but I thought this might be a useful primer for those who have expressed interest in my work.

It also introduces the notion of morality ‘inside-out’ and morality ‘outside-in’. This one way I characterise my approach to looking at morality and doing ethics, and one I’ll elaborate in more detail with a full post soon. In fact, I’m considering turning the chapter on moral naturalism, where I talk about morality inside-out, into a paper suggesting an outside-in approach to ethics is complementary to the conventional metaethical approach, and is something philosophers should take more seriously.

But, for now, here’s the preface:


The Ethical Project: The Future of Ethics

This is the last in my series in response to Philip Kitcher’s new book, The Ethical Project. You can read my initial review, my look at our evolving moral psychology, on moral functionalism, and my last post on ethical progress. In this post I want to sum up my thoughts on Kitcher’s naturalistic programme and make some comments on where to from here.

As is probably apparent from the other posts in this series, I’m very sympathetic with Kitcher’s broad approach to ethics. He calls is naturalistic pragmatism – naturalistic because it doesn’t lean on any non-natural or a priori truths, but on the gritty reality of life in the natural world; pragmatist because of his commitment to a Deweyan picture of philosophy being “reconnected with human life”, and “ethics as growing out of the human social situation”, as well as a Jamesian pragmatic approach to truth (p3).

If I had to give my approach to ethics a label, I’d be quite content to call it pragmatic naturalism.

I thoroughly endorse the notion that ethics is a human invention, a cultural innovation that served the function of solving the problems of social living, thus facilitating greater levels of cooperation. That individual moral norms are best understood as strategies for solving these problems and encouraging prosocial behaviour.

I also dismiss notions of there being moral facts – in the sense of a unique domain of facts that are knowable a priori, and/or non-natural, and/or intrinsically normative, and/or the expressions of a divine will. There is only us, our interests, the dynamics of social living, and the mundane fact that if we want to live socially, and reap the benefits of cooperation, we need to abide by some rules of behaviour lest it all spiral down into mutual defection.

And, as I don’t believe that morality is a special domain, I dismiss the is-ought problem and the naturalistic fallacy as barking up the wrong tree. The kind of special ‘ought’ that is apparently separated from ‘is’ simply doesn’t exist. The simple undefinable moral property of ‘the good’ also doesn’t exist. The fallacies are, well, a fallacy.


The Ethical Project: Evolving Moral Minds

In my last post I offered my initial review of Philip Kitcher’s new book, The Ethical Project, which is a bold attempt to offer a thoroughly naturalistic rendering of ethics, devoid of any divinity or dubious metaphysics. And overall, I’m very pleased with the account – not least because it is largely in sync with my own.

For too long has ethics been dominated by discussions of moral semantics, of naturalistic fallacies, of rational agents and an expectation that once we discover moral truths, people will kick themselves for not having happily obeyed them in the past.

But this is not the only way to talk about morality. Instead of seeing morality as a truth-seeking endeavour, or springing from the will of some deity, we can alternatively look at morality from what Owen Flanagan, Hagop Sarkissian and David Wong (2008) call “human ecology”.

Better than defining morality by what it is – i.e. about truth, about happiness, about god’s will etc – we can define morality by what it does. This, at its heart, is the moral functionalist perspective. It’s central to Kitcher’s account (as it is to mine), and I believe it’s key to understanding morality as a natural phenomenon – i.e. a practice enacted by human beings throughout history through to this day.

And once we understand better what morality does, we might gain some insights into what it is, and even how we ought to behave. Thus, shockingly, this descriptive programme might have normative implications.

In this post I explore some of the themes raised in The Ethical Project and add some elements of my own research to fill in some gaps left by Kitcher. I have more to say than will fit in one post, so I’ll add more after this one.


Review: The Ethical Project

Pop back in time roughly five million years to the time of the last common ancestor of humans and chimpanzees, and you’d likely spot roving troops of creatures not dissimilar to today’s great apes. Yet, while chimpanzees and the rest of our evolutionary cousins have changed relatively little over the last few million years, our species has undergone remarkable change.


Arguably the strongest driving force for this incredible evolutionary change is our uniquely social nature – and our uniquely moral proclivities – to the point where today we interact in a global network of billions of individuals, a network of staggering complexity hinging on levels of cooperation unmatched by any other creature.

And the glue that holds our social and cooperative life together is morality.

It’s in charting and explicating this progression from the earliest forms of pre-moral inclinations to our modern day complex moral deliberations that is the ambitious goal of Philip Kitcher’s new book, The Ethical Project.

And Kitcher, John Dewey Professor of Philosophy at Columbia University, does a remarkable job of not only weaving together a coherent picture from many disparate threads, but also lays down a path for potentially fruitful ethical debate in the future. And he does it all in a thoroughly naturalistic, empirically-aware and refreshingly grounded way, with his method strongly influenced by his commitment to “pragmatic naturalism”, which heavily informed particularly by John Dewey and William James.

He also espouses a theory that is startlingly close to my own PhD thesis, much to my joy and chagrin. Even if there are now a few less revelations in my own thesis, it is deeply heartening to see that I’m not the only one charting an evolutionarily-informed naturalistic account of morality.

That said, there are a few gaps in Kitcher’s account, and a few key details that he overlooks either deliberately or unintentionally. In this post, I’ll outline the main thrust of Kitcher’s argument, and in a subsequent post I’ll provide a more critical review, comparing and contrasting it with my own account.

First, an overview of Kitcher’s argument.


Values and Moral Pragmatism

There are values, and there are the values that promote them. This is a distinction that is worth drawing, because it carves values up between intrinsic (whether they are ontologically privileged or just held to be such) and instrumental values.

But what I want to suggest is that it’s the second-order, instrumental, values that actually take priority over the first-order values when push comes to shove. And the real trick in constructing a healthy, functional and robust moral system is navigating the push and pull of the second-order values rather than quibbling over first-order values. This is what I characterise as ‘moral pragmatism’.
