Abstract
In this thesis I determine what is required in an account of money. I compare John’s Searle’s idea of institutions, as ontologically subjective, to Francesco Guala’s idea of an institution as a functional, rule-based equilibrium. I find both, as accounts of money, to be inadequate on their own. In response, I develop a new account of money which has functional components akin to Guala’s but with the addition of intentionality. This adds mind-dependence back into the account of money but, if Khalidi’s theory of social kinds is correct, my account of money is still open to scientific investigation, because it might be kind of natural.
