Preview

An analogy is developed between action in an indeterministic setting and choice under uncertainty, as it is studied in decision theory. Various dominance relations among actions are explored, and used both to provide a semantic account of what agents ought to do and to formulate a notion of dominance act utilitarianism. The ideas are related to problems involving independence, conditionals, and sure‐thing reasoning.

Keywords: act utilitarianism; conditionals; decision theory; dominance; independence; sure‐thing reasoning
