Rationally Speaking

Cosmologist Sean Carroll is one of many who have recently answered the annual question posed by Edge.org, which this year was: What scientific idea is ready for retirement? Sean, whom I’ve met at the Naturalism workshop he organized not long ago, and for whom I have the highest respect both as a scientist and as a writer, picked “falsifiability.”

I’ve been reading for a while now Jim Baggott’s Farewell to Reality: How Modern Physics Has Betrayed the Search for Scientific Truth, a fascinating tour through cutting edge theoretical physics, led by someone with a physics background and a healthy (I think) dose of skepticism about the latest declarations from string theorists and the like.

Gay marriage is rapidly becoming less and less controversial, at least in the Western world. Yes, the battle hasn’t been won just yet, both in Europe and in the US, but we are getting there at a pace that would have been unthinkable just a few years ago.The next frontier, it seems, is adoptions by gay parents. When I talk to even some of my somewhat progressive friends and relatives, including those in the Old Country, they seem to resist the idea of gay couples adopting children much more than they resisted (if they ever did) the idea of gay marriage. Why?

Here comes another post on ethics! This one is, I must admit, somewhat meta-ethical, despite my recent post about the limited value of meta-ethical discussions when it comes to debates in first-order ethics. As I pointed out in the discussion that followed that essay, it’s not that I don’t think that meta-ethics is interesting, it’s just that it shouldn’t be used as an excuse for refusing to get down and dirty about actual everyday moral questions.

I used to have the “meta” itch, but I learned to live with it and stop scratching it. It only irritates anyway, without doing much good work. Let me explain. If you are a regular (or even occasional) reader of Rationally Speaking you know that we often publish essays that have to do with ethics and moral philosophy. That's because ethics is one of those things that always lurks in the background (and sometimes the foreground) of our lives, whether we reflect on it or not. And I of course think it is better to reflect on it, at least from time to time.

In a forthcoming episode of the Rationally Speaking podcast, Julia and I discuss the philosophy and science of suicide, i.e. what empirical inquiry tells us about suicides (who commits them, how, what are the best strategies for prevention) and how philosophical reflection may lead us to think of suicide. In this post I will focus on the philosophical side of the discussion, for which an excellent summary source, with a number of additional references, is this article by Michael Cholbi in the Stanford Encyclopedia of Philosophy, to which I will keep referring below.

I am not particularly friendly to the so-called New Atheism.

So the other day Julia Galef and I had the pleasure of interviewing mathematical cosmologist Max Tegmark for the Rationally Speaking podcast. The episode will come out in late January, close to the release of Max’s book, presenting his Mathematical Universe Hypothesis (MUH). We had a lively and interesting conversation, but in the end, I’m not convinced (and I doubt Julia was either).

Is there such a thing as moral expertise?Good question, right? I’ve been thinking more about it for a few weeks now as a result of an interesting talk by Gopal Sreenivasan (Duke University) entitled “Moral expertise and the proto-authority of affect,” which he gave at CUNY’s Graduate Center.

People who identify with the various versions of the skeptic / atheist / rationalist / freethinking movement(s) hold up the Enlightenment, the famous “Age of Reason,” to be the pinnacle of human civilization, as well as a model for future progress.

As I’ve mentioned on other occasions, my most recent effort in philosophy of science actually concerns what my collaborator Maarten Boudry and I call the philosophy of pseudoscience. During a recent discussion we had with some of the contributors to our book at the recent congress of the European Philosophy of Science Association, Maarten came up with the idea of the pseudoscience black hole. Let me explain.

I’m getting a little tired of writing about the relationship between science and philosophy when it comes to ethics, as I’ve made my views abundantly clear on this blog and elsewhere. Nonetheless, more than one of my readers has exhorted me to take on Richard Carrier’s arguments to the effect that science can answer moral questions, as these arguments are allegedly much better than those advanced by more prominent skeptics, such as Sam Harris and Michael Shermer.
