Reasoning about Closure
The specter of epistemic closure haunts current epistemology: some regard the refutation of closure as obvious, while others take its denial to be an epistemic
outrage. To some extent, the strong difference of opinion has its source in certain misapprehensions. This paper tries to formulate and clarify the key issues dividing the two sides and contends that, in certain respects, the difference between the friend and the foe of closure may be more a matter of semantics than substance. The paper goes on to argue that once the substantial issues have been properly formulated, there is a limit to how far deductive reasoning can take the parties to the dispute.
