ABSTRACT
The purpose of this paper is to show that the KFK Principle (KFK) is fundamentally wrong. The argument for that claim is:
Knowledge requires doxastic justification.
Doxastic justification for inferentially known proposition arises only for a person, S, when S employs sufficiently good reasons for believing the known proposition.
Those sufficiently good reasons must be propositionally justified but need not be doxastically justified.
KFK requires that the beliefs containing the reasons be doxastically justified.
Therefore, KFK is fundamentally wrong.
