Who is Saul Aaron Kripke?June 26, 2021
Emeritus American philosopher and logician from Princeton University.
The American philosopher Kripke, who has done seminal studies in the fields of logic and philosophy of mathematics, especially modal logic, intuitive logic and set theory, also contributed to other branches of philosophy such as philosophy of language, epistemology, metaphysics and philosophy of mind.
Kripke’s early works, A Completeness Theorem in Modal Logic, 1959 and Considerations on Modal Logic, 1963 concentrate on the technical problems of modal logic. The most influential of these positions can be found in Naming and Necessity (Naming and Necessity, 1980—Kripke also has an article published in 1972 with the same name) in which Kripke asserts that identity is never between two things, but between the thing and itself, and is based on necessity. claims (to some philosophers this number of Kripke’s is rather questionable)
For example, the identity of the person who finds the bifocal glasses and the general manager of the PTT may easily seem contingent, rather than mandatory, but Kripke argues that the contingent here is the collection of both separate features in one person and this contingency does not eliminate the necessity of the person being identical with himself Benjamin Franklin, the general manager of PTI, who found the bifocal glasses Kripke, in his work on Naming and Necessity, constructs a theory of causal meaning that argues that names are not only precise descriptions, but also demonstrative phrases whose referent must be valid in all possible worlds. Another important book by Kripke is Wittgenstein on Rules and Private Language (1982), which Wittgenstein puts in the context of “following private language reasoning”.
