 It should moreover be evident, given the discussion of the Sure Thing Principle (STP) in  Section 3.1,  that Jeffrey’s theory does not have this axiom. Since states may be probabilistically dependent on acts, an agent can be represented as maximising the value of Jeffrey’s desirability function while violating the STP. Moreover, unlike Savage’s, Jeffrey’s representation theorem does not depend on anything like the Rectangular Field Assumption. The agent is not required to have preferences over artificially constructed acts or propositions that turn out to be nonsensical, given the interpretation of particular states and outcomes. In fact, only those propositions the agent considers to be possible (in the sense that she assigns them a probability greater than zero) are, according to Jeffrey’s theory, included in her preference ordering.
