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.

Moral Ecology Updated

I’ve gone though a few iterations of moral ecology already. My last iteration focused on the notion that it takes a multitude of behavioural strategies working in concert to promote high levels of cooperation within groups, and on the complex dynamics of the interactions between these strategies over time. I still think that’s true, but it’s not the full picture.

So it’s time I updated that picture a bit in light of further progress I’ve made. As such, here is the latest rendering of moral ecology to warm your cockles or curl your toes.

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…

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:

Am I Really a Moral Relativist?

Relativism is one of those terms more often used in the pejorative than in any serious philosophical sense. It’s like a cautionary sign at the edge of a cliff pronouncing “Caution! Precipice ahead!” Any argument in ethics that steers towards relativism – or even any argument that steers away from objectivity and absoluteness – sets off the usual slew of anti-relativism klaxons.

Yet as I delve deeper into writing my thesis, I can already hear the klaxons blaring.

Now, those who have read my previous posts on moral ecology might be surprised to hear that I’m beginning to see it as a form of relativism. After all, I suggest that the problems that morality is trying to solve have no single solution, and often it requires multiple approaches working in concert (or in tension) to get the best outcomes.

That sounds relativist. And while I’m becoming more aware of that link, I hasten to highlight the differences between any Moral Ecology Brand Relativism from the more No-Name Brands that gather dust on the back shelf in the moral supermarket.

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…

Evolution and Moral Ecology Abstract

There’s a conference coming up later this year in Sicily on the evolution of morality, appropriately called: The Evolution of Morality: The Biology and Philosophy of Human Conscience. Looks like a cracker. Speakers include Frans de Waal, Phillip Kitcher, Patricia Churchland, Richard Joyce, Owen Flanagan and Simon Blackburn, among others. Read more…

Moral Disagreement

If there’s one uncontested fact in ethics, it’s that just about everybody disagrees with just about everybody else on at least one moral issue, probably many more. That’s moral disagreement for you, and it’s a topic of great concern to many moral philosophers and metaethicists. Except that moral philosophy somewhat Read more…
