The uncertainty we face comes in many varieties: uncertainty about the state of the world, uncertainty about the results of our possible interventions, uncertainty about what is rational, and uncertainty about what is ethical.

Some of this uncertainty can be reduced by gathering further information but uncertainty cannot be completely eliminated. We are, thus, to some extent, always in the dark and yet we must press on: choosing careers, deciding where to live, deciding how best to tackle environmental problems, choosing our political leaders, and so on.

Fortunately, there is a well-developed theory of decisions under uncertainty.

In this talk, Professor Mark Colyvan will outline this theory and discuss some of its strengths and limitations. In particular, showing how the theory of decisions under uncertainty can be employed in the service of ethical decisions.
