This could almost be true

Funny piece in The Onion.

Cosmos cleans up

Cosmos magazine, the popular science magazine for which Jenny and I both do freelance work, pretty much cleaned up in the annual Bell Awards, presented in Sydney last week. These awards are for the publishers of business-to-business, specialist, and niche consumer magazines. Cosmos won the award for magazine of the year, plus seven other awards - including the editor of the year award to Wilson de Silva, not to mention the award for best website.

Wrong for real?

In his book Sentimental Rules, Shaun Nichols reports some fascinating research that suggests young children are hardline moral objectivists, who think that if something is morally wrong it is "wrong for real", and that this is a kind of "default setting" in the metaethics of common sense. If that suggestion is accepted, even some moderate theories of moral realism should actually be held as error theories, or as containing an element of moral scepticism, in so far as they maintain that moral truths are grounded in human nature and would not be true for alien beings with a different psychological makeup. This moderate kind of moral realism, for which I have a degree of sympathy, must hold hardline moral objectivism to be an error: if commonsense morality endorses hardline moral objectivism, then the moderately realist theories must hold commonsense morality to be mistaken.

This suggests to me that any moral theory that remains plausible on considered reflection is going to be, to some extent, an error theory. But why should that be surprising? The whole history of the advance of human knowledge shows common sense gradually being revealed as a poor indicator of the way the universe really works. It provides models that are pragmatically useful in the evolutionary and historical circumstances that shaped it - someone following these models in the past would have kept out of trouble. However, there is no reason to believe that commonsense models accurately track the larger reality of which our lives are a very small part. In fact, we have pretty good reason by now to assume that common sense is likely to be wrong whenever it strays beyond giving us the most pragmatic, everyday advice.

Welcome to G magazine

I've just had an initial glance at the first issue of G, an environmentally friendly - hence green, hence "G" - lifestyle magazine published by the same combination of people who do Cosmos. The first issue looks good, and it includes a whole batch of reviews by Jenny. Welcome to G, and may it have a long and successful run.

Libertarian free will

I've had some interesting correspondence about the concept of libertarian free will since I discussed this in the context of Lee M. Silver's Challenging Nature. I maintain that the idea has never been developed in a form that is intellectually coherent, and that there is no real prospect that it ever will be.

That raises two related groups of issues. First, if I am correct is it a tragedy? Putting it another way, how deeply are we committed to this idea as part of our ordinary concept of ourselves as agents? What have we lost if the idea needs to be jettisoned? In my view, it is not a tragedy at all, since compatibilist free will is the only kind of free will worth having, but I expect a lot of people will disagree with me. Since I was a child, I've never found the idea of libertarian free will even slightly plausible, but I am probably in the minority on that. Second, have we fully thought through the implications, not only for theology and philosophy of religion but also for many of our social practices, such as those of reward and punishment? It is at least possible that some of our important practices make metaphysical assumptions that cannot be supported by reason. If so, what then?

East, West, Christian, post-Christian - what's the buzz?

A simplistic way of looking at Lee M. Silver's Challenging Nature: The Clash of Science and Spirituality at the New Frontiers of Life is to see it as an exploration of contrasting Eastern and Western attitudes toward biotechnology, and contrasting (yet strangely similar) attitudes toward it within the West, where a further distinction can be made between the largely Christian US and the largely post-Christian nations of Europe.

There is more to the book than this, but the critical point seems to be that Western culture is haunted by monotheism, even in nations where few people believe in the orthodoxly conceived God of the Abrahamic tradition. For many who have been influenced by New Age or environmentalist beliefs, Nature is now seen as a kind of god with a will that we must not defy - a sort of matriarchal successor to the traditional deity. As Silver perceives the situation, even individuals who claim to be entirely secular in their approach are frequently influenced by pervasive forms of Western spirituality.

By contrast, Silver argues, Eastern belief systems and forms of spirituality do not emphasise the will of any single god, and they have no concept that nature in its current form must not be violated.

This thesis is intended to explain why European nations have been especially hostile to the genetic engineering of food, which is seen as contrary to a certain conception of the natural order, while the US has been relatively relaxed about allowing GM crops, despite widespread and fiercely expressed opposition to anything that could be seen as tinkering with human souls. On the other hand, industrialised nations in Asia, such as Japan, Singapore, and Korea, show little inclination to reject biotechnology.

I am, of course, simplifying the argument and the book's broader scope. However, even this simplified version of Silver's thinking is worth discussion. There is some evidence that gives it support, since biotechnology has encountered a much lower level of emotional resistance in Eastern countries, raising the possibility that those countries may (continue to) be less willing to prohibit or regulate research of kinds that are considered morally problematic in the West. If that is the case, they are likely to take the lead in the development of many aspects of twenty-first-century biotech.

Silver's new book

I've been in a reading frenzy over the past few weeks, partly to make up for lost time - for a combination of reasons, I've been getting little reading done this year, at least by my standards.

Currently, I'm reading Lee M. Silver's new book, Challenging Nature, a defence of biomedical science, and biotechnology more generally, against more or less irrational attacks from both the right and left of politics. It's a goldmine of information, and Silver's thinking is sometimes more sophisticated than that of many philosophers and bioethicists who have considered the same issues. But he does sometimes overreach.

For example, early in the book, he attacks the belief in free will, as if such a belief must be unscientific. He doesn't seem to realise that most philosophers (though, to be fair, perhaps not most philosophers who have been publishing about the problem of free will in recent years) are compatibilists. I.e., we see free will and physical determinism as compatible.

[Note: since writing the above, I see that Silver does briefly describe compatibilism in an endnote, which shows the peril of commenting on a book halfway through reading it and the peril of not always checking the endnotes straightaway. That said, the popularity of compatibilism still provides one reason why it is unwise to criticise people for believing in free will unless their actual beliefs have been probed very carefully.]

On the compatibilist conception, free will is not the freedom to act in a way that somehow transcends physical nature, of which our brains and bodies are part. It simply means the freedom to act without being subject to certain kinds of coercion, manipulation, inner compulsion, etc.

I doubt that there is such a thing as free will in any absolute sense, i.e. we may sometimes know all the facts, with no additional fact of the matter in borderline cases that "this person is acting with free will" and "this person is not". It is just that there are various things we fear, which we see as impediments to acting as we would really like to: we fear people putting guns at our heads; we fear being overtaken by some psychiatric condition that drives us to act in ways that strike us as alien and would cause us trouble; we fear addiction to drugs, which could compel us to act in ways that, again, are against our current values; we fear being tricked into acting against our better judgment; we fear (not very seriously) the science-fictional prospect of a mad scientist taking over control of our personalities by wiring us to his damnable machine. On this conception of free will, I act freely whenever I act in accordance with my own values and beliefs, without being compelled by any of these feared things. It may be a matter of degree, as when economic circumstances may greatly limit my range of options - still, although we do fear poverty we don't usually interpret economic circumstances as taking away free will, exactly. This may be because they (usually) still leave a range of possible actions, rather than compelling one in particular. We can consider ourselves to be acting freely within the boundaries of having limited resources.

It seems to me that this is the only kind of free will worth having (as Daniel Dennett has argued, though Dennett might not agree with all my exposition above). The spooky contra-causal free will that metaphysical libertarians claim we possess does not even make sense to me, and Silver evidently feels the same way. However, I do think that we have free will in the worthwhile and meaningful sense ... at least most of the time, and at least to a large degree.

In short, people who - when asked - say that we possess free will are not necessarily claiming anything incoherent or mystical. If we want to find out how many have the spooky libertarian belief that Silver is deriding, we need to ask a different question. It is not enough just to ask people something like "Do you believe in free will?" I expect most people would answer yes, but would probably not have a metaphysically libertarian theory in mind, or even necessarily some version of compatibilism. They might mean little more than that they are not fatalists, who believe that human decisions are futile, or something of the sort.

Of course, if it turns out that the popular concept of free will is the spooky libertarian one, I am quite happy to be an error theorist about that concept. Unless things are different in the US - and, in fairness to Silver, maybe they are - I doubt that anything like this is meant by most of us when we use the expression in our ordinary lives. In fact, it looks to me like something dreamed up by theologians wanting to explain how there can be evil in the world when an all-powerful, perfect being is supposedly in charge - how could that being somehow not be responsible for evil? Answer: we act in ways that simply have no physical causes and cannot be traced back to the creative acts of God. Belief in free will does not entail commitment to anything as difficult and metaphysical (possibly even irrational) as that.

Gould on science and religion

With all the current controversy about Richard Dawkins' new book, The God Delusion, and the relationship between science and religion, I went back to my article on Stephen Jay Gould's book on the subject, Rocks of Ages, to remind myself what I said in the past.

Entitled "Stephen Jay Gould on Science and Religion", the article was first published in Quadrant magazine in 2000, and a copy of it now sits happily on my website (it has also been anthologised, and it can probably be found on Quadrant's site as well). I can't really improve on what I wrote then. I still think that Gould was wrong in his claim that science and religion are "non-overlapping magisteria" that can never properly contradict each other; I'm still convinced that the problem was that he wanted to impose a narrow view of the proper scope of religion, confining it to a sphere of values (though allowing it to eat up the entire field of ethics). This is not tenable. Religions have always made claims that are open to rational investigation by science. This is their prerogative - they are encyclopedic explanations of the world and the human situation - but also a potential weakness if they make claims that later seem untenable when empirical evidence is gathered.

Some religious thinkers may, indeed, retreat to making only claims that seem immune to any sort of empirical investigation, but this is not religion's essence. Such a retreat is a very recent and culturally confined phenomenon, and it leaves religious worldviews eviscerated.

Spider-Man 3

For something a bit lighter, I've just read in Jason Rosenhouse's Evolutionblog that Spider-Man 3 will feature Sandman as its supervillain.

As a kid, I rated this character (who is not to be confused with the totally different character created by Neil Gaiman) among my favourite villains. He can turn his body to sand, or to solid rock, or a mixture, can take any shape, packs a helluva punch in his rocky form, and cannot be hurt by any amount of force (enough force can break rock, but he can just turn to sand and reform). There's scope here for some great special effects if it's done right.

I'm not such a huge fan of the Spider-Man movies - can pretty much take them or leave them - but this one might be a lot of fun.

What we eat

I'm currently reading The Ethics of What We Eat (published under a different title in the US) by Peter Singer and Jim Mason. I'll be reviewing this elsewhere, so I won't comment at length here.

The book brings home why I admire Singer so much - enormous effort must have gone into the research, and the whole thing is written in a way that is very understanding to people who don't meet the authors' view of what, morally speaking, might be the best food choices in all the circumstances. Ethical omnivores need not feel shrilly lectured to by the vegan authors, who are not going to demand total change in anybody's life, and less-ethical-than-we'd-like-to-be omnivores are allowed to ... well, simply wriggle in our seats, while also worrying about the cumulative picture building up to suggest we need to make some changes. And build up it does. This is advocacy of a very powerful kind, partly because of its relative gentleness.
