==Adopting the Logic of possibility in the Einstein's General Theory of Relativity==

[[Einstein]] asserted in his book ''The meaning of Relativity'' (1922) that according to his conviction the possibility of explaining the numerical equality of [[inertia]] and [[gravitation]] by the unity of their nature is a sufficient reason for holding [[General Theory of Relativity]] as superior over the conceptions of classical theories and for considering all the difficulties encountered when making a way for his new theory "as small" in this respect.<ref>{{cite book |author=Marco M.

|quote=The importance of the asserted identity of the two masses was stressed by Einstein in unambiguous terms: ''The possibility of explaining the numerical equality of inertia and gravitation by the unity of their nature gives to the general theory of relativity, according to my conviction, such a superiority over the conceptions of classical mechanics, that all the difficulties encountered must be considered as small in comparison with this progress.''}}</ref>
