Metaphysics- Is water necessarily identical to H2O?: An argument

Thesis - 5 pages - Physics

Kripke holds that the declaration “water is identical to H2O” is necessarily true. According to Kripke, this true statement is only knowable through experience (a posteriori), and cannot be determined by definitions of words only. Even though it is only a posteriori, Kripke...
