Abstract
Expressions such as ‘morality requires’, ‘prudence requires’ and ‘rationality requires’ are ambiguous. ‘Morality’, ‘prudence’ and ‘rationality’ may refer either to properties of a person, or to sources of requirements. Consequently, ‘requires’ has a ‘property sense’ and a ‘source sense’. I offer a semantic system for its source sense. Then I consider the logical form of conditional requirements, in the source sense.
