 Examples are easily found that exhibit the problematic nature of this division between the two disciplines. Compare the act of throwing down a brick on a person from a high building to the act of throwing down a brick from a high building without first making sure that there is nobody beneath who can be hit by the brick. The moral difference between these two acts is not obviously expressible in a probability calculus. An ethical analysis of the difference will have to refer to the moral aspects of risk impositions as compared to intentional ill-doing. More generally speaking, a reasonably complete account of the ethics of risk must distinguish between intentional and unintentional risk exposure and between voluntary risk-taking, risks imposed on a person who accepts them, and risks imposed on a person who does not accept them. This cannot be done in a framework that treats risks as probabilistic mixtures of outcomes. In principle, these outcomes can be so widely defined that they include all relevant moral aspects, including rights infringements as well as intentionality and other pertinent mental states. However, this would still not cover the moral implications of risk taking per se, since these are not inherent properties of any of the potential outcomes.
