Quote of the day

My own judgement is that the nanotechnology revolution has the potential to change America on a scale equal to, if not greater than, the computer revolution. As Chair of this Subcommittee, I am determined that the United States will not miss, but will mine the opportunities of nanotechnology.

~Sen. Ron Wyden (D-Ore.)

The ethics of advanced technologies

Today, I had an email conversation with The NanoEthics Group Research Director, Patrick Lin. Patrick informed me of an upcoming nanoethics symposium (*) for the International Journal of Applied Philosophy. "Comprised of papers from some of the most respected thinkers in the field, the symposium is the first in nanoethics to appear in a leading academic philosophy journal - highlighting the increasing urgency and attention surrounding nanotechnology's ethical and societal implications."

The following is an abstract from their paper that introduces the symposium:

Nanoethics is a contentious field for several reasons. Some believe it should not be recognized as a proper area of study, because they believe that nanotechnology itself is not a true category but rather an amalgamation of other sciences, such as chemistry, physics and engineering. Critics also allege that nanoethics does not raise any new issues but rather revisits familiar ones such as privacy. This paper answers such criticisms and sets the context for the papers that follow in this nanoethics symposium.

Here is my reply to Patrick regarding the abstract:

Is your justification for the study of nanoethics that nanotechnologies will have such huge impact that they deserve study in their own rights? It seems to me that you could turn the critic’s complaint of "not a true category but rather an amalgamation of other sciences" around and say "it is precisely because nanotechnologies will broadly impact all these old-school categories that we need to study it."

And here is Patrick’s reply:

Actually, my justification for the pursuit of nanoethics is a three-pronged argument, in which what you mentioned might only be part of it. Basically:

(1) There's no reason for us to accept the litmus test that "in order for X to be a category/field in its own right, it must pick out unique issues not already covered elsewhere." Under this litmus test, we might have to collapse chemistry and biology into the single field of physics (which governs the interactions of all physical matter, including chemical elements and emergent biological processes), but that doesn't seem right. Also, if this litmus test were right, we could also perhaps argue that "bioethics" should not be recognized as a proper field of study, since its questions could be reduced to familiar ones in the pre-existing fields of privacy (patient rights), autonomy (right to die), theology (abortion), etc.

(2) Even if that were a good litmus test before, nanotechnology - and its ethics - seems to break the old rules insofar that nanotech itself is an amalgamation of other fields (unless you want to bite the bullet and argue that nanotechnology itself should not be recognized as a field of its own; but this seems to be a losing fight given the amount of money being poured into nanotech as its own area of research...nanotech already has a life of its own).

(3) Nanoethics does in fact raise unique issues not found elsewhere (e.g., the invisibility cloak, molecular manufacturing) or at least adds a significantly new dimension to related debates (e.g., privacy, economic justice).

Also, my argument above is more a semantic one and not so much a call to action. I'm not sure that many people would argue that we do not need to study the possible impacts of the set of technologies that make up "nanotechnology"; the need to worry about our future should be more or less clear already. Rather, their argument is more that we don't need to create a new field of study called "nanoethics" because those questions are already being investigated in bioethics, computer ethics, etc.

However, I would disagree with their argument: by neatly categorizing those questions under the umbrella of "nanoethics," we highlight the fact that nanotechnology is so far-reaching and will be directly responsible for profound changes to our world. Perhaps those who argue otherwise are trying to slip nanotechnology "under the radar" by not giving it or its ethics a name, i.e., "you don't need to worry about nanotech; it's really just a repackaging of familiar sciences and issues"…but I don't buy that - nanotech/ethics appears to be greater than the sum of its parts...
