The frame problem is the problem of how we selectively apply relevant knowledge to particular situations in order to generate practical solutions. Some philosophers have thought that the frame problem can be used to rule out, or argue in favor of, a particular theory of belief states. But this is a mistake. Sentential theories of belief are no better or worse off with respect to the frame problem than are alternative theories of belief, most notably, the “map” theory of belief.

Justifying a belief gives reason to think that the belief is true. So our concept of justification contains a ‘truth connection’. I canvass a number of proposals for analysing this. In the end, two competing conceptions of the truth connection remain: the first, that justifying a belief makes the belief objectively probable, the second, that justifying a belief makes the belief probable in a world which would make true our other beliefs. I discuss reasons for embracing and rejecting these two (...) versions of the truth connection. Ultimately, the two versions appear to represent distinct but equally plausible conceptions of justification. I conclude by rejecting the proposal that these truth connections respectively capture internalist and externalist conceptions of justification. (shrink)

Among the difficulties that sentential theories of belief face, the problem of clutter asserts that treating beliefs as sentences would make it difficult or impossible to literally fit the number of beliefs possessed by ordinary human cognizers into the mind-brain. I argue that concerns about clutter arise from a misunderstanding of how belief states, whether sentences or not, are causally related. Insofar as a weak computer model of the mind treats information states as virtual states, I explain how the ontology (...) of virtual states seriously mitigates the problem of clutter for sententialism.
