What will nanotechnology bring?

A spectrum of views: extreme predictions, modest predictions, and in between

Page 3: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

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!

Page 4: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Extreme predictions: the hype

Or on the gloomier side – out-of-control nanobots devouring the earth!

Page 5: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Extreme predictions: Drexler and Kurzweil

Page 6: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Extreme predictions in ficiton

Page 7: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

More modest predictions

Fancy nanoengineering won’t work!

1. Too sticky2. Brownian motion

The most we can hope for may be ….

Modest predictions

somewhat better soap.

What will nanotechnology bring?

Most nanoscientists think the truth lies somewhere in between …

which is pretty exciting!

Page 10: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

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?

Page 11: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

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?

Page 12: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Thinking About EthicsEthics is a branch of philosophy.What is philosophy?

Subject matter: questions about the ultimate nature of reality, knowledge, & valueMethod: dialectic = reflective equilibration

Page 13: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Three Main Branches of Philosophy

Metaphysics: nature of realityEpistemology: nature of knowledgeAxiology: nature of value

Branches of axiology: ethics (moral value), aesthetics (artistic value)

The Method of Philosophy: Dialectic

As in a crossword puzzle, so in dialectic, questions we can answer help us with questions we can’t answer.

Consistency.

Page 23: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

What Is Ethics?Subject-matter: good and

bad, right and wrong.

Method: reflective equilibration.

(John Rawls, 1921-2002)

Page 24: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Reflective EquilibrationAchieving coherence among

our beliefs

Balancing general principles against particular cases

Crossword puzzle method

(Susan Haack, b. 1945)

Page 25: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Reflective EquilibrationSocrates (c. 470-399

BCE) called it dialectic

Page 26: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

The Method of Philosophy: Dialectic

Example from

Plato’s dialogue

Laches, featuring

Socrates (c. 470-399 BCE)

Page 27: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Socrates vs. Laches:What Is Courage?

1st definition: standing firm in battle

Page 28: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Socrates vs. Laches:What Is Courage?

1st definition: standing firm in battle

Problem: too narrow

Page 29: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Socrates vs. Laches:What Is Courage?

2nd definition: willingness to face danger

Page 30: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Socrates vs. Laches:What Is Courage?

2nd definition: willingness to face danger

Problem: when foolish, not admirable, so not a virtue, so not courageous

Page 31: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Socrates vs. Laches:What Is Courage?

3rd definition: wise willingness to face danger

Page 32: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Socrates vs. Laches:What Is Courage?

3rd definition: wise willingness to face danger

Problem: takes more courage to act without wisdom

Page 33: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

The Method of Philosophy: Dialectic

Laches is led to revise uncertain views about the definition of courage by appeal to other views.

DIALECTIC!

Dialectic in Action:The Debate Over Utilitarianism

Utilitarianism: The right action is whichever action produces the greatest total amount of social benefit (“the greatest happiness of the greatest number”)

Page 35: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Jeremy Bentham (1748-1832) John Stuart Mill (1806-1873)

Page 36: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Dialectic in Action:The Debate Over Utilitarianism

The Organ Donor Case (ODC):

You can save five patients by killing one and redistributing his organs. Should you?

Page 37: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Dialectic in Action:The 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.

Page 38: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Dialectic in Action:The Debate Over Utilitarianism

Utilitarian argument:It’s a mistake to assume that

utilitarianism says to kill in ODC.

Sometimes better to aim at goal indirectly.

Page 39: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Dialectic in Action:The Debate Over Utilitarianism

Francis Bacon (1561-1626):

Experiments of fruit vs. experiments of light

Also: referees

Page 40: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Dialectic in Action:The Debate Over Utilitarianism

Utilitarian argument:Likewise, a general policy of sacrificing

few to many would make all of society nervous

Make society better off by committing ourselves to a principle prohibiting such sacrifices

Page 41: The Methodology of Moral Reasoning Nanoethics Lecture I Roderick T. Long Auburn Dept. of Philosophy.

Dialectic in Action:The Debate Over Utilitarianism

Anti-Utilitarian argument:- If commitment is absolute,

utilitarianism has been abandoned- If commitment isn’t absolute, problem

isn’t solved- In any case, gives right answer for

wrong reason
