 If the project…is successful, it will have been shown not only that the concept of information provides a primitive for the analysis of both the physical and the mental, but also that states of information…existed previously to states of mind. Since information in this sense is prior to mentality, but also implicated in all mental states, it follows that information is prior also in the ontological sense…Success of the present project thus will show that an ontology of informational states is adequate for an explanation of the phenomena of mind, as distinct from an ontology of physical events. [And Sayre adds:] It is a reasonable conjecture that an ontology of information is similarly basic to the physical sciences…. (Sayre 1976: 16)
