Protagoras (c. 490 - c. 420 BC) was a Presocratic Greek philosopher.
Diogenes Laertius' book "Lives of the Philosophers" is source for many early Greek philosophers including Protagoras; but this work was compiled over six hundred years after Protagoras' death and consequently not accurate. Plato also wrote about Protagoras, considering him a sophist; Aristotle regarded Protagoras as who first introduced a spiritual principle, as a sober man among the inebriated.
Protagoras' doctrines can be divided into three groups:
1. Orthoepeia: the study of the correct use of words 2. Man-measure statement: the notion that knowledge is relative to the knower 3. Agnosticism: the claim that we cannot know anything about the gods. [1]
He could be considered an agnostic and relativist. He also was involved in the question of whether virtue could be taught or not.
- "Man is the measure of all things".
Greek philosophers, Gorgias and Hippias were also Sophists.
