However, if this is the Canberra procedure, then there is no reason to think of it as appealing to analytic knowledge at any stage. A Ramsey sentence of the kind at issue says that there actually exists some entity satisfying certain requirements (there is a kind of state that is caused by perceptions …). Sentences like this make eminently synthetic and falsifiable claims. It is not a matter of definition that humans actually have internal states that play the causal role associated with the concept of belief. The Canberra strategy thus seems no different from the prescription that philosophy should start with the synthetic theories endorsed by everyday thought, and then look to our more fundamental theories of reality to see what, if anything, makes these everyday theories true. This seems entirely in accord with methodological naturalism—philosophy is in the business of assessing and developing synthetic theories of the world.
