Greek philosopher Plato, for example, quotes Socrates as saying: “The soul, . . . if it departs pure, dragging with it nothing of the body, . . . goes away into that which is like itself, into the invisible, divine, immortal, and wise, and when it arrives there it is happy, freed from error and folly and fear . . . and all the other human ills, and . . . lives in truth through all after time with the gods.”​—Phaedo, 80, D, E; 81, A.

Of Plato, to whose philosophy the common ideas about the English “soul” may be attributed (as is generally acknowledged), it is stated: “While he sometimes speaks of one of [the alleged] three parts of the soul, the ‘intelligible,’ as necessarily immortal, while the other two parts are mortal, he also speaks as if there were two souls in one body, one immortal and divine, the other mortal.”​—The Evangelical Quarterly, London, 1931, Vol. III, p. 121, “Thoughts on the Tripartite Theory of Human Nature,” by A. McCaig.
