Defending The Multiple Realization Argument Against The Identity Theory, David Barrett

Graduate Theses and Dissertations

A classic argument in the philosophy of mind is that the identity theory is false because mental state types are multiply realized in brain state types. In this dissertation I provide a detailed elaboration of the argument and a defense of it against a few of its prominent contemporary critics. Finally I offer empirical evidence from inter-species differences in humans and monkeys, and also from a case of extensive neural plasticity, which shows that mental state types are multiply realized in brain state types.
