As this page shows, I put my nose in many pots. But the unifying theme is big picture questions for humanity. Some of these questions are about ethics and values. Others have to do with methodology and how we make predictions or deal with uncertainty. Still others pertain to specific concerns and possibilities, such as existential risks, the simulation hypothesis, artificial intelligence, life-extension, human enhancement, and the transhumanist movement (in which I've been involved as co-founder and chair of the WTA).

As a species, we are not adept at thinking about these questions. Pessimistically, one might hold that we are so bad at thinking about them that it is a good thing that we usually ignore them. Attempting to wake up without succeeding would only give us bad dreams. Perhaps. But how will we know unless we try?

 
MAY 2008
Recently returned from Arizona, Utah, Montreal. Working on two papers, one on moral uncertainty, the other on ethical issues related to artificial intelligence; and a short article on the Fermi paradox (update: now published in Technology Review; preprint will be available here shortly); and a collaborative roadmap project for brain emulation technology; and a book review. Also thinking about the general challenges of rationality/wisdom in relation to big picture issues for humanity.

ETHICS & POLICY

The Fable of the Dragon-Tyrant
Recounts the Tale of a most vicious Dragon that ate thousands of people every day, and of the actions that the King, the People, and an assembly of Dragonologists took with respect thereof. [J Med Ethics, 2005, Vol. 31, No. 5, pp. 273-277] [translations: Hebrew, Finnish, Spanish, French, Slovenian, Dutch, Russian] [html | pdf]
The Reversal Test: Eliminating Status Quo Bias in Applied Ethics
We present a heuristic for correcting for one kind of bias (status quo bias), which we suggest affects many of our judgments about the consequences of modifying human nature. We apply this heuristic to the case of cognitive enhancements, and argue that the consequentialist case for this is much stronger than commonly recognized. (w/ Toby Ord) [Ethics, Vol. 116, No. 4 (2006): pp. 656-680] [pdf]

Astronomical Waste: The Opportunity Cost of Delayed Technological Development Suns are illuminating and heating empty rooms, unused energy is being flushed down black holes, and our great common endowment of negentropy is being irreversibly degraded into entropy on a cosmic scale. These are resources that an advanced civilization could have used to create value-structures, such as sentient beings living worthwhile lives... [Utilitas, Vol. 15, No. 3 (2003): pp. 308-314] [html | pdf]

Infinite Ethics
Cosmology shows that we might well be living in an infinite universe that contains infinitely many happy and sad people. Given some assumptions, aggregative ethics implies that such a world contains an infinite amount of positive value and an infinite amount of negative value. But you can presumably do only a finite amount of good or bad. Since an infinite cardinal quantity is unchanged by the addition or subtraction of a finite quantity, it looks as though you can't change the value of the world. Aggregative consequentialism (and many other important ethical theories) are threatened by total paralysis. We explore a variety of potential cures, and discover that none works perfectly and all have serious side-effects. Is aggregative ethics doomed? [pdf]
Dignity and Enhancement new
Does human enhancement threaten our dignity as some have asserted? Or could our dignity perhaps be technologically enhanced? After disentangling several different concepts of dignity, this essay focuses on the idea of dignity as a quality (a kind of excellence admitting of degrees). The interactions between enhancement and dignity as a quality are complex and link into fundamental issues in ethics and value theory. [Commissioned for The President's Council on Bioethics, (2008): forthcoming] [pdf]
In Defense of Posthuman Dignity
Brief paper, critiques a host of bioconservative pundits who believe that enhancing human capacities and extending human healthspan would undermine our dignity. [Bioethics, Vol. 19, No. 3 (2005): pp. 202-214] [translations: Italian, Slovenian] [This paper has been chosen for inclusion in a special anthology of the best papers published in this journal in the past two decades] [html | pdf]

The Wisdom of Nature: An Evolutionary Heuristic for Human Enhancement new
Human beings are a marvel of evolved complexity. Such systems can be difficult to enhance. Here we describe a heuristic for identifying and evaluating the practicality, safety and efficacy of potential human enhancements, based on evolutionary considerations.

The Future of Human Evolution
This paper explores some dystopian scenarios where freewheeling evolutionary developments, while continuing to produce complex and intelligent forms of organization, lead to the gradual elimination of all forms of being worth caring about. We then discuss how such outcomes could be avoided and argue that under certain conditions the only possible remedy would be a globally coordinated effort to control human evolution by adopting social policies that modify the default fitness function of future life forms.

Cognitive Enhancement: Methods, Ethics, Regulatory Challenges new
Cognitive enhancement comes in many diverse forms. In this paper, we survey the current state of the art in cognitive enhancement methods and consider their prospects for the near-term future. We then review some of ethical issues arising from these technologies. We conclude with a discussion of the challenges for public policy and regulation created by present and anticipated methods for cognitive enhancement. [w/ Anders Sandberg] [Science and Engineering Ethics, 2007, forthcoming] [pdf]
Why I Want to be a Posthuman When I Grow Up new
After some definitions and conceptual clarification, I argue for two theses. First, some posthuman modes of being would be extremely worthwhile. Second, it could be good for human beings to become posthuman. [Forthcoming in Medical Enhancement and Posthumanity, eds. Bert Gordijn and Ruth Chadwick (Springer), 2007] [pdf]

A History of Transhumanist Thought
The human desire to acquire new capacities, to extend life and overcome obstacles to happiness is as ancient as the species itself. But transhumanism has emerged gradually as a distinctive outlook, with no one person being responsible for its present shape. Here's one account of how it happened. [Journal of Evolution and Technology, 2005, Vol.14, No. 1] [pdf]

Existential Risks: Analyzing Human Extinction Scenarios and Related Hazards Existential risks are ways in which we could screw up badly and permanently. Remarkably, relatively little serious work has been done in this important area. The point, of course, is not to welter in doom and gloom but to better understand where the biggest dangers are so that we can develop strategies for reducing them.

When Machines Outsmart Humans
This slightly more recent article briefly reviews the argument set out in the previous one, and notes four immediate consequences of human-level machine intelligence. [Futures, 2003, Vol. 35, No. 7, pp. 759 - 764, where it appears as the target paper of a symposium, together with five commentaries by other people, to which I had the opportunity to reply in the next issue.]
Are You Living in a Computer Simulation?
This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching the posthuman stage; (2) any posthuman civilization is extremely unlikely to run significant number of simulations or (variations) of their evolutionary history; (3) we are almost certainly living in a computer simulation. It follows that the naïve transhumanist dogma that there is a significant chance that we will one day become posthumans who run ancestor-simulations is false, unless we are currently living in a simulation. A number of other consequences of this result are also discussed. [Philosophical Quarterly, 2003, Vol. 53, No. 211, pp. 243-255] [pdf | html] Also with a Reply to Brian Weatherson's comments [Philosophical Quarterly, Vol. 55, No. 218, pp. 90-97]

PHILOSOPHY OF SCIENCE & PROBABILITY

anthropicAnthropic Bias: Observation Selection Effects in Science and Philosophy
Failure to consider observation selection effects result in a kind of bias that infest many branches of science and philosophy. This book presented the first mathematical theory for how to correct for these biases. It also discusses some implications for cosmology, evolutionary biology, game theory, the foundations of quantum mechanics, the Doomsday argument, the Sleeping Beauty problem, the search for extraterrestrial life, the question of whether God exists, and traffic planning. Five sample chapters are online along with a brief primer. [Routledge, New York, 2002]
Self-Locating Belief in Big Worlds: Cosmology's Missing Link to Observation
Current cosmological theories say that the world is so big that all possible observations are in fact made. But then, how can such theories be tested? What could count as negative evidence? To answer that, we need to consider observation selection effects. [Journal of Philosophy, 2002, Vol. 99, No. 12, pp. 607-623] [html | pdf]

A Primer on the Doomsday argument
The Doomsday argument purports to prove, from basic probability theory and a few seemingly innocuous empirical premises, that the risk that our species will go extinct soon is much greater than previously thought. My view is that the Doomsday argument is inconclusive - although not for any trivial reason. In my book, I argued that a theory of observation selection effects is needed to explain where it goes wrong. [Colloquia Manilana (PDCIS), 1999, Vol. 7; reprinted in The Actuary, March 2001, and in ephilosopher.com, 2001] [translations: Russian]
Sleeping Beauty and Self-Location: A Hybrid Model new
The Sleeping Beauty problem is an important test stone for theories about self-locating belief. I argue against both the traditional views on this problem and propose a new synthetic approach. [Synthese, Vol. 157, No. 1 (2007): pp. 59-78] [pdf]

When driving on the motorway, have you ever wondered about (and cursed!) the fact that cars in the other lane seem to be getting ahead faster than you? One might be tempted to account for this by invoking Murphy's Law ("If anything can go wrong, it will", discovered by Edward A. Murphy, Jr, in 1949). But there is a deeper explanation, based on observational selection effects... [PLUS, 2001, No. 17]

PHILOSOPHY OF MIND

If two brains are in identical states, are there two numerically distinct phenomenal experiences or only one? Two, I argue. But what happens in intermediary cases? This paper looks in detail at this question and suggests that there can be a fractional (non-integer) number of qualitatively identical experiences. This has implications for what it is to implement a computation and for Chalmer's Fading Qualia thought experiment. [Minds and Machines, 2006, Vol. 16, No. 2, pp. 185-200] [pdf]

 

FAILED STAND-UP COMEDIAN

Before taking up my current post as director of the Future of Humanity Institute at Oxford University, I was a British Academy postdoctoral research fellow here in the Faculty of Philosophy. Before that, I was a lecturer at Yale University.

Beside philosophy, I also have a background in physics, computational neuroscience, mathematical logic, and artificial intelligence. My performance as an undergraduate set a national record in Sweden. Prior to becoming a tweedy academic, I dabbled in painting and poetry, and for a while I did stand-up comedy in London.

I co-founded the World Transhumanist Association in 1998 to encourage public engagement with the prospects of future technologies being used to enhance human capacities. The WTA, a non-profit grassroots organization, now has some 4,400 members from all over the world, and local chapters in many countries. Later, I co-founded the Institute for Ethics and Emerging Technologies, a virtual think tank.

In the early days, a common reaction was "this is just science fiction". But in the last few years, it seems that both academia and the public are gradually ceasing ignore what is arguably one of the most important issues of our time: how we might use our growing technological powers to improve human lives by ensuring access to a wide set of options for prolonging healthy lifespan, augmenting cognition, and improving emotional well-being. Discussions no longer get stuck on whether human enhancement will ever be possible, although time-scales for specific developments are highly uncertain. Rather, the focus is increasingly on ethics - whether it ought to be done. This is a bit of progress.

The enhancement debate frequently gets polarized into two opposing ideological camps, transhumanists vs. bioconservatives. That is unfortunate. Hopefully, a further few years hence, we will finally enter the more constructive phase where we ask not whether human enhancement is good in general, yes or no, but rather questions like: Which enhancements, exactly? How to solve the myriad technical problems? What kind of regulation and public policy and funding priorities do we need? What cultural challenges will we face and how to deal with them? We also need to think more about the risks and about how to make opportunities available globally.

THE BIG PICTURE

I want to understand the big picture: our place in the world and the long-term prospects for intelligent life. It would be good to learn to think about such matters without resorting to wishful thinking, mysticism, hype, myopia, or anthropocentrism, but that is not easy.

The big picture is worthy of study in its own right. It seems ennobling to try to expand our horizons beyond our own little corner of the world and its ephemeral concerns.

Theoretical fascination, however, is not the only mainspring of my quest. Corny as it sounds, I want to help make the world a better place. One reason why big picture questions are important is that their answers might affect what outcomes we should expect from our own technological development, and therefore - indirectly - what policies it makes sense for us to pursue. Unless we understand something of the big picture, how can we know where we ought to be going?

It seems quite likely that humanity will in this century master technologies that will enable us to overcome many of our current biological limitations. Possible outcomes range from extinction to lives wonderful beyond imagination. We might at last get the opportunity to truly grow up and experience life as it should have been all along. If things develop quickly enough, the benefits might even be enjoyed by ourselves or our children.

In addition to transformative technology, we need the wisdom and the good will to use it well. In my view, all of us ought to have the option of becoming ageless creatures with vastly enhanced intellectual, emotional, and moral capacities. Why aim for less? Human life in its present form can be breathtakingly, amazingly fantastic, as you know when you experience it at its best. Yet even these best moments are, perhaps, merely dull premonitions of what is in principle possible.

JUNE 2007
Wisdom is distinct from cleverness or mental efficiency. Wisdom is about getting the big things right. A prerequisite is the ability to recognize what the big things are, i.e., a sense for proportion, for what is important. I am often thinking about this: What if I am overlooking something essential or getting a big thing wrong? Then whatever progress I'm making is in vain. It is worse than useless to travel fast and far if one is going in the wrong direction. How can one reduce the probability of such fundamental error? And of course, if one spends too much of ones time worrying about such questions, one never gets anywhere at all. In the ideal world, perhaps one would have two lives. In the first life, one would figure out what the right direction is. In the second life, one would set off in that direction at one's maximum pace. As things stand, one is left to make a half-hearted compromise between recklessness and paralysis.
