R.C. Sproul on Protagoras and Humanism
The Consequences of Ideas (Good News Publishers: 2009), p. 29.
Protagoras, probably the most influential Sophist in Athens, is frequently described by modern historians as the "father of humanism." His famous maxim, "Homo mensura," declares that "man is the measure of all things," of the existence of things that are and of the nonexistence of things that are not. ¶ From a biblical perspective, of course, the honor of being the first humanist does not belong to Protagoras. Indeed, it is accorded not to a man, but to a serpent whose maxim was "Sicut erat Dei," "You will be like God" (Gen. 3:4).
