n.
Group of itinerant professional teachers, lecturers, and writers prominent in Greece in the later 5th century BC.
The sophistic movement arose at a time when there was much questioning of the absolute nature of familiar values and ways of life. An antithesis arose between nature and custom, tradition, or law, in which custom could be regarded either as artificial trammels on the freedom of the natural state or as beneficial and civilizing restraints on natural anarchy. Both views were represented among the sophists, though the former was the more common. Their first and most eminent representative was Protagoras ; other notable sophists include Gorgias of Leontini, Prodicus, Hippias, Antiphon, Thrasymachus, and Critias. A later "second sophistic school" existed in the 2nd century AD.
