I disagree with this characterization of the Sophists. That they don't care about 'truth' and only rely on rhetoric. Rhetoric is the rigorous application of logical constrains - A sophist would say that the only discernable 'truth' is whatever can be stated consistently and without logical contradiction, and any other criteria are just subjective dogmatism. Much of the negativity directed at the Sophists is due largely to Plato and Aristotle's disparaging writings, and are not particularly fair characterizations - they are ad hominem attacks from individuals who had no logical or rhetorical argument capable of refuting their positions, were butt hurt about this, and resorted to fallacy and smears

For almost all of western history, Gorgias has been a marginalized and obscure figure in both philosophical thought and culture at large.[40] In the nineteenth century, however, writers such as the German philosopher Georg Wilhelm Friedrich Hegel (1770–1831) and the English classicist George Grote (1794–1871) began to work to "rehabilitate" Gorgias and the other Sophists from their longstanding reputation as unscrupulous charlatans who taught people how to persuade others using rhetoric for unjust causes.[40] As early as 1872, the English philosopher Henry Sidgwick (1838–1900) was already calling this the "old view".[40] Modern sources continue to affirm that the old stereotype of the Sophists is not accurate.[40]
