  7. Abstract:
  8. In Naming and Necessity and Identity and Necessity, Kripke convinced many that there are necessary propositions which are knowable only a posteriori. Kripke’s examples of these propositions can be placed into three categories: 1) Some mathematical propositions like Goldbach’s conjecture (the conjecture that every even integer greater than 2 can be expressed as the sum of two primes) 2) Scientific truths like “Water is H2O”, “Gold has the atomic number 79”, etc. 3) Identity statements flanked on both sides with proper names; like “Hesperus is Phosphorus”, “Cicero is Tully” and the like (in the rest of this article, these three categories will be called, respectively, the first, the second and the third group of propositions). In this dissertation , the modal and epistemological status of the propositions of these groups, especially the third group, are being investigated and it is tried to show that the propositions of the first group being knowable only a posteriori would be an objectionable matter; Also regarding the doctrines of essentiality of origin and what I will call essentiality of substance, the propositions of the second group are both necessary and knowable only a posteriori; and the propositions of the third group can’t be both necessary and knowable only a posteriori
