ABSTRACT
Before considering ways of empirically investigating what is in the mental logic, it seems a necessary preliminary, in order to avoid seeming to presuppose what should be argued, that we discuss reasons why it is plausible to expect there to be a mental logic in the first place, and what sort of mental logic those reasons should lead one to expect. So we begin with these sorts of preliminaries, and they will, we hope, situate the concept of a mental logic in a theoretical framework within which it makes sense-one that includes the notion of an innate syntax of thought.
