"A philosophical account of risk, such as this book provides, states what risk is, which attitudes to it are rational, and which acts affecting risks are rational. Attention to the nature of risk reveals two types of risk, first, a chance of a bad event, and, second, an act's risk in the sense of the volatility of its possible outcomes. The distinction is normatively significant because different general principles of rationality govern attitudes to these two types of risk. Rationality strictly regulates attitudes to the chance of a bad event and is more permissive about attitudes to an act's risk. Principles of rationality governing attitudes to risk also justify evaluating an act according to its expected utility given that the act's risk, if any, belongs to every possible outcome of the act. For a rational ideal agent, the expected utilities of the acts available in a decision problem explain the agent's preferences among the acts. Maximizing expected utility is just following preferences among the acts. This view takes an act's expected utility, not just as a feature of a representation of preferences among acts, but also as a factor in the explanation of preferences among acts. It takes account of an agent's attitudes to an act's risk without weakening the standard of expected-utility maximization. The view extends to evaluations of combination of acts, either simultaneous or in a sequence. Applications cover hedging, return-risk evaluation, professional advice, and government regulation"--
