Sophists (sŏfˈĭsts) [key], originally, itinerant teachers in Greece (5th cent. B.C.) who provided education through lectures and in return received fees from their audiences. The term was given as a mark of respect. Protagoras was perhaps the first to style himself a Sophist and to receive payment for his instruction. He and Gorgias were respected thinkers, but others after them, notably Thrasymachus and Hippias, and many lesser figures, turned education into the development of skills useful to political careers. Hence, they cared little for the disciplined search for truth (dialectics), teaching in its place the art of persuasion (rhetoric). Although not properly speaking a philosophical school, they appear to have shared a basic skepticism regarding the possibility of knowing truth. The more notorious of them boasted of their ability to "make the worst appear the better reason." They were criticized by Plato and Aristotle for their emphasis on rhetoric rather than on pure knowledge and for their acceptance of money, a judgment that has passed into history and has given the term sophist its present meaning. George Grote's History of Greece (1846) was one of the first defenses of the Sophists. Modern studies have stressed the contributions of Protagoras and Gorgias to a theory of knowledge and to ethics. They are frequently cited today as forerunners of pragmatism.
