Scientific philosophy has demonstrated that a simple element (‘simple’ meaning ‘not composed’) is indestructible, eternal. The soul, not being a composition of elements, is, in character, as a simple element, and therefore cannot cease to exist. The soul, being of that one indivisible substance, can suffer neither disintegration nor destruction, therefore there is no reason for its coming to an end.
