In this essay I consider reality as understood in verificationism or in pragmatism such that it is “the end of enquiry”. In this framework reality can be given a one to one correspondence with the ontology of a hypothetical best possible theory of physics capable of answering all possible questions as long as “best” includes the condition of being the simplest. If this theory can be written in the language of mathematics, as will be motivated by its need to describe information, then reality admits a mathematical representation.
