 Different theorists differ, not just in their views about what propositions are, but also in their views about what a theory of propositions should explain. The representational properties of propositions are a case in point. Hanks, King, and Soames take one of the primary tasks of a theory of propositions to be the explanation of the representational properties of propositions. Others, like McGlone (2012) and Merricks (2015), hold that a proposition’s having certain representational properties is a primitive matter. Still others, like Richard and Speaks, deny that propositions have representational properties in any interesting sense. See for further discussion of these issues the entry on  structured propositions.
