Representationalism and the sense-datum theory each have simple accounts of entailment relations between qualia-statements grounded in the structure of the objects of experience.

Now notice that there are many entailment relations between qualia-statements—for example, ‘\(e\) has \(Q_{Rx \amp Sq(x)}\)’ entails ‘\(e\) has \(Q_{Rx}\)’, and ‘\(e\) has \(Q_{Rx \amp Tr(x) \amp By \amp Sq(y)}\)’ entails ‘\(e\) has \(Q_{Rx \amp Sq(y)}\)’, and so on. The orthodox representationalist and the sense-datum theorist have simple accounts of these entailments in terms of the structure of the objects of experiences (apparent structure, for the representationalist; actual structure, for
