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…

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: 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.

Top 10 Books of All Time

Yeah, all time. I could even say Top 10 Books in All Possible Worlds. They’re that awesome.

People often ask me what are my favourite books, or the books that have most influenced me – in philosophy, science, history etc. So I figured I’d post ’em here to fuel my laziness; if I’m asked in future, I can just give a URL. Nice.

The Iliad – Homer

Sing, o muse… Not sure what’s more astounding, that it’s one of the first written works in human history, or that it’s still one of the most profoundly moving books, dripping with pathos and turgid prose the likes of which a pitiful writer like myself can only dream. I mean, rosy fingered Dawn, who spread her light across the lands of the deathless gods and mortal men. Sublime.

There’s a also lesson in reading in reading the Iliad, too. It’s the catalogue of ships. It’s almost the peer of all the begetting in Genesis (well, I assume Genesis is worse because I’ve never made it through that whole section). But it’s like you have to earn the rest of the tale. That makes it all the more epic. In fact, every epic has a catalogue of ships. My thesis has its literature review…

Although I still have an unresolved question: who would win in a fight between Achilleus and Arjuna. Man, that’d be an epic bout.

From Genes to Politics: How Biology Influcences the Way You Vote

It might seem a leap too far, but bear with me, because I’m going to attempt to show that genes influence the way you vote. Let’s start at the end and work our way towards the beginning.

Your adopted political ideology strongly influences the way you vote. Certainly, there might be circumstances in which a liberal might vote for a conservative candidate, such as if the liberal candidate was an obvious dud (or the conservative candidate was a shining star), or if the conservative candidate happened to offer a better policies for the present environment (say, being a hawk in a time of war). But, all things being equal, self-identifying liberals vote for liberal candidates and parties.

However, your political ideology isn’t something you come to adopt from out of the blue. We’re not political blank slates. One of the greatest influences on what ideology you adopt is your worldview, which I loosely define as the implicit framework you use to make sense of the world around you.

Your worldview is both descriptive and prescriptive – it helps understand the way the world is, and it’s value-laden, so it helps you understand good and bad, desirable and undesirable. Many empirical and theoretical studies have shown that underneath our political attitudes lie (often unconscious) beliefs about the way the world is.

Morality and the Obsession with Harm and Fairness

Where you can find contemporary moral philosophers talking about the content of morality (instead of their preferred pastime of quibbling over metaethics), you’ll often find them talking about issues concerning harm and fairness. But is this all there is to morality? What of moral prohibitions concerning food, or cleansing rituals, or burial practices? Can you just translate such norms into norms about harm and fairness? Or is the domain of morality larger than many philosophers might readily suggest?

This was one of the questions broached by ANU’s Ben Fraser in a seminar at Sydney University yesterday. Fraser’s paper was about the limits of the moral domain, specifically defending Richard Joyce’s account of morality from criticisms mounted by Stephen Stich. I won’t cover everything said by Fraser (you can read his entire paper here), but I am particularly interested in what it is that we’re really talking about when we’re talking about morality.

And I tend to believe that defining morality in terms of harm/fairness exclusively is a bit narrow – but understandable. Even so, we shouldn’t limit ourselves to issues of harm/fairness if we want to understand the full scope of morality and moral phenomena.

Politics is Psychology

Which comes first, psychology or politics? Contrary to popular belief, it’s psychology.

Politics is often talked about as if it’s about ideology first, and that people are drawn to a particular ideological stance because of their life circumstances – i.e. grow up in a working class family and you’ll vote left; grow up in a wealthy family and you’ll vote conservative – or that we are able to detach ourselves from our individual circumstances and reflect on political ideology in an idealised rational way, and we eventually settle on what we think is the ‘correct’ political ideology.

But it’s not like that.

Certainly, circumstance plays a roll, as does reason. But the dominant factor that decides the political ideology we’re likely to identify with is our psychological disposition and accompanying worldview.

This is the sentiment underpinning my recent analysis of a speech given by our new Prime Minister, Julia Gillard, published on the ABC’s Drum website today. The analysis isn’t as much about her political views as the implicit worldview that underpins them.
