Closure Intuitions and Restriction

In this article I consider some alleged intuitive costs concerning the denial of the full generality of the Principle of Closure for knowledge. Usually philosophers dismiss such denial as highly counter-intuitive but I argue that, at least with regard to the alleged costs here considered, this is wrong: given our folk-intuitions, there are no such costs. So a fallibilist who seeks to halt the closure-based sceptical argument can restrict the principle with no such intuitive costs.
