Overview

The Sophists were itinerant teachers in classical Athens who taught rhetoric, argumentation, and the art of persuasion for a fee. Far from mere charlatans, thinkers like Protagoras and Gorgias raised profound questions about the nature of truth, the conventionality of morals, and the power of language to shape reality.

Key ideas

  • Relativism: Protagoras declared 'man is the measure of all things' — truth and value are relative to the perceiver, not fixed by nature or the gods.
  • Nomos vs. Physis: The Sophists debated whether justice, morality, and law (nomos) are natural or merely conventional — a question that remains central to political philosophy.
  • Power of Rhetoric: Gorgias demonstrated that language can make the weaker argument appear stronger, raising questions about the relationship between persuasion, truth, and power.

Positions held

Reacts to

  • Eleaticism

    Gorgias' On Not-Being turned rigorous Eleatic argument against Parmenides' conclusions — that nothing is, that if it is it cannot be known, and that if known it cannot be communicated.

Later connections

  • Platonism Reacted to this tradition

    Plato's dialogues argue sustainedly against Sophistic relativism and rhetoric, defending objective truth and the good against 'man is the measure'.
