Sophist

The dialogue stages an extended inquiry into the nature of the sophist and the possibility of falsehood, employing systematic divisions to classify kinds of production and imitation and to separate opinion from knowledge. It argues that not-being must be understood relationally as difference, enabling meaningful predication of negation, and it addresses linguistic and logical puzzles that render sophistry persuasive. By analyzing imitation, appearance, and rhetorical contrivance, the discussion distinguishes genuine philosophical knowledge from dissembling speech and outlines methods of definition, cross-division, and refutation. Recurring themes include the ontology of difference, the limits of language, and the use of dialectical procedure to expose fallacy.
