What will nanotechnology bring?
  • A spectrum of views extreme predictions, modest
    predictions, and in between

3
Extreme predictions the hype
  • Immortality!
  • Godlike powers!
  • Nanobots inside us curing all diseases!
  • The ability to build or remold anything,
    including ourselves, from the atomic level up!

4
Extreme predictions the hype
  • Or on the gloomier side out-of-control nanobots
    devouring the earth!

5
Extreme predictions Drexler and Kurzweil
6
Extreme predictions in ficiton
7
More modest predictions
  • Fancy nanoengineering wont work!
  • 1. Too sticky
  • 2. Brownian motion
  • The most we can hope for may be .

8
Modest predictions
  • somewhat better soap.

9
What will nanotechnology bring?
  • Most nanoscientists think the truth lies
    somewhere in between
  • which is pretty exciting!

10
Even on a moderate view, nanotechnology raises
issues of ethics
  • How should we balance public welfare and safety
    against academic freedom of researchers?
  • How can we compare the weights of national
    security, corporate profit, public good,
    individual rights, environmental impact, and
    integrity of scientific enterprise?

11
Even on a moderate view, nanotechnology raises
issues of ethics
  • How should the benefits of, and/or the control
    over, nanotechnology be justly distributed?
  • What are the ethical implications of altering
    human nature via nanotechnology?

12
Thinking About Ethics
  • Ethics is a branch of philosophy.
  • What is philosophy?
  • Subject matter questions about the ultimate
    nature of reality, knowledge, value
  • Method dialectic reflective equilibration

36
Dialectic in ActionThe Debate Over
Utilitarianism
  • The Organ Donor Case (ODC)
  • You can save five patients by killing one and
    redistributing his organs. Should you?

37
Dialectic in ActionThe Debate Over
Utilitarianism
  • Anti-Utilitarian argument
  • If utilitarianism were true, then in the ODC we
    should kill.
  • But surely it would be wrong to kill in the ODC.
  • So utilitarianism is false.

38
Dialectic in ActionThe Debate Over
Utilitarianism
  • Utilitarian argument
  • Its a mistake to assume that utilitarianism says
    to kill in ODC.
  • Sometimes better to aim at goal indirectly.

Dialectic in ActionThe Debate Over
Utilitarianism
  • Anti-Utilitarian argument
  • - If commitment is absolute, utilitarianism has
    been abandoned
  • - If commitment isnt absolute, problem isnt
    solved
  • - In any case, gives right answer for wrong reason
