The Study and Criticize of Relation Between Self Evidence and Clarity & Certainty

In Islamic philosophy four definitions have been represented about self evidence and speculative knowledge which its common definition is “required to think and not required to anything of think”.Explaining conceptual and extensional relationships of self evidence with concepts such as clarity or certainty would help us not to mistake and not to mix different aspects of epistemology together and so, protect ourselves from epistemic mistakes.In this article, self evidence has been compared with clarity & certainty from the conceptual perspective. It has been concluded that the common definition of self-evidence from the point of conceptualization has nothing to do with certainty & clarity, although this conclusion cannot be said about other uncommon definitions.Also, among the self-justified proposition, only the vejdanyyat propositions require these concepts and only the apriori & vejdanyyat & estimative propositions require the certainty and the others don’t have any relation with these concepts.
