Going on a Moral Diet

It’s a well established fact that there is no such thing as a free lunch. This is particularly the case when that lunch consists of deep fried chicken followed by a couple of glazed doughnuts and a Coke.

We love sweet and fatty foods (although, as Dan Dennett points out, we don’t desire them because they taste good, they taste good because we desire them). And even though they’re contributing to an epidemic of obesity today, it’s a damn good thing that we do love the sweets and the fats. Because had we not vigorously pursued such energy-rich sources of nutrition throughout our evolutionary past we may not have made it to the point where today’s obesity epidemic was even an option.

hamburgerSimply put, an evolved taste for sweet and fatty stuffs – in the form of a strongly reinforcing sensation of pleasure in response to exposure to sweet and/or fatty foods – was adaptive because our highly active endothermic bodies with their calorie-burning brains required vast amounts of fuel to keep them hunting and gathering and surviving and reproducing, etc.

And up until the last few moments of our evolutionary history, we were far more likely to be undernourished rather than overnourished. That being the case, the cost of getting it wrong and consuming too much energy was lower than the cost of getting it wrong and not consuming enough. Hence a selective pressure in favour of our sweet/fatty tooth.

Yet today we can see all this. We can acknowledge that allowing our evolved sweet-and-fat-seeking psychological impulses take over can lead us to unhealthy ends. The heuristic is now pointing in the wrong direction. We understand that we need to inhibit our evolved impulses and steer our behaviour towards more appropriate ends in today’s environment. We understand that sometimes we need to consciously manage our diet.

Maybe we need to do the same when it comes to some of our evolved moral impulses.

Morality Inside-out

Most moral enquiry – particularly metaethical enquiry – is conducted in an arse-backwards way. Most philosophers appear to look at morality from the inside-out. And I’d suggest this inside-out view of morality is hampering our ability to understand the nature of morality in all its glorious messy complexity. What we Read more…

Politics as Biology: Explaining the Razor Edge of Partisan Politics

Following Obama’s re-election, M.S. at The Economist ponders the startlingly improbable situation in the United States where such a strongly partisan country can keep rolling out elections that are knife edge finishes:

This is what strikes one most strongly looking back at America from across an ocean: the country seems repeatedly embroiled in savage 51-49 electoral campaigns, and it seems to be increasingly paralysed by irresolvable rancour between right and left.

And think about it for a second: this is bizarre. If Americans are in fact divided between two extremely different political ideologies, it would be an extraordinary coincidence if each of those philosophies were to hold the allegiance of nearly equal blocs of support. That situation ought not to be stable. Adherence to these two ideologies ought to shift enough just due to demographics that the 50-50 split should deteriorate. And yet the even split seems to be stable. What’s going on?

Good question. Here’s a speculative answer, using the tools of population biology as a lens to understand politics:

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:

Which Comes First: The Moral, Or The Ecology?

There are chicken and egg problems. And there are tail and dog problems. The thing is, I’m not sure which of these problems I’m facing at the moment in regards to defining moral ecology.

I recently had a very fruitful, if highly critical, experience at the Philosophy of Biology at Dolphin Beach workshop. Amidst the splendour of the New South Wales south coast, and between midnight bonfires on the beach, I gave a paper on evolution and moral ecology.

The thesis was this:

The highly variegated hominin social environment of the last few million years shaped our psychology to produce a polymorphism of psychological traits that promote a range of behavioural strategies when it comes to social living.

For example, the inherent difficulties in identifying trustworthy partners for potentially risky cooperative ventures has made some people naturally more predisposed towards being trusting and others towards being suspicious.

Another example might be that some people are predisposed to be quick to anger, particularly in the face of perceived disloyalty or defection in cooperative ventures, and others are predisposed towards being more forgiving.

These predispositions promote behaviours that follow fairly predictable patterns – more trusting people engage in more cooperative ventures but expose themselves to greater risk of defection; more forgiving people maintain more social bonds by punishing less but make norm enforcement more difficult.

Moral Ecology Defined (At Last)

I recently found myself confused about the meaning of the term ‘moral ecology.’ This proved to be an unsettling experience, namely because I’m the one who coined the term (with a little help from John S. Wilkins). Given that moral ecology features centrally in my thesis, it’s probably important that Read more…

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: Measuring Ethical Progress

In this post, I consider the notion of ethical progress. It follows on from my review of  Philip Kitcher’s The Ethical Project, then my post looking at the evolution of our moral psychology, and a post on moral functionalism.

One of the core themes of Kitcher’s is to chart, and account for, the notion of ethical progress. If we look back on the changes that have occurred in ethics through history and across cultures, is there any thread that we might declare as representing ‘progress’?

Does the move from a draconinan eye-for-an-eye lex talonis code of punishment to more moderate restitution and rehabilitation represent progress? Was emancipation progress? Was expanding womens’ rights progress? We want to say they were. But on what grounds?

This is ostensibly a problem for a naturalistic anti-realist account of morality – one such as Kitcher’s (and my own) – because there are no immutable moral truths (a priori, non-natural and/or divinely mandated) to which we can peg progress; ethical progress can’t simply be likened to scientific progress, where we gain a deeper understanding of ethical truth and then put it into practice.

Kitcher’s response to this problem is, I believe, the correct one. Once we acknowledge that ethics is a human invention which, according to the functionalist rendering, was created to solve the problems of social living (or “remedy those altruism failures provoking social conflict”, in Kitcher’s version), we can start to make sense of ethical progress.

The Ethical Project: Functionalism and Disagreement

In my first post on Philip Kitcher’s The Ethical Project I outlined his main argument. In the second post I addressed his account of the evolution of our moral psychology, and filled in a few gaps with my own account that I’m elaborating in my PhD thesis. In this post I look at moral disagreement and functionalism

People disagree about moral issues. There’s probably no other statement in ethics that is as uncontroversial. But what such disagreement means, and how to resolve it – if it’s resolvable at all – is a hotly contested topic.

But if we take the moral functionalist approach – as espoused by Kitcher, and endorsed by myself in my thesis – then we can gain a crucial insight into the origins, and possible resolutions, of moral disagreement.

Let’s start with some typical disagreements. Person A says lying is always wrong. Person B says lying is sometimes right. Then they argue. We wouldn’t be surprised if one appealed to a moral norm they believe in, such as “do not lie”. Another might suggest that lying is against the will of god. Or they might say that lying causes harm to someone’s autonomy. Or that it reduces the overall happiness, and overall happiness is the greatest good. And on they go.

Note that these are all justifications.

Now, comparing justifications is one way of conducting an ethical debate. But I think the evidence suggests that many of our justifications for our moral norms are spurious. If you don’t happen to believe in moral truths or in a divine moral authority (as I don’t), then you can immediately question appeals to them as a defensible justification.

There is also ample moral psychology research that suggests we are easily confused about the justifications of our moral norms. Jon Haidt’s ‘moral dumbfounding’ and the ubiquitous trolley dilemmas show that people offer a range of different justifications seemingly as post-hoc rationalisations for deeply held intuitions about right and wrong. So it’s not the justifications that are doing the heavy lifting, it’s something else.

You can also see this in many contemporary moral debates – such as over abortion or over the moral status of social welfare – where two interlocutors offer their arguments, and then have them torn to shreds by the other side, but no-one changes their mind. Sigh.

Now, I think there are good justifications for certain moral practices. I’m just sceptical whether the justifications that most people cite in everyday moral discourse actually are the right kind of justifications.

So, to understand moral disagreement – and where it really occurs – we need to look elsewhere. And this is where functionalism comes in.
