Can internalism integrate a correct analysis of the concept of knowledge?

This essay tries to show, inside the internalism-externalism dispute, that internalist theory of doxastic justification in useless in obtaining conceptual analysis of knowledge. To show this point, first we try to fix a basis through which we could make an adequate evaluation of the internalist proposal. So, this essay tries, in the most accurate way, to fix the philosophical question in dispute by those proposals. After enunciating it, this essay tries to draw one or more responses from the internalist proposal. With the internalist response in hands, we try to show that it is false and, therefore, that it is not useful to obtain a true analysis of the concept of knowledge.
