Sophist philosophy challenged traditional Greek thought with relativism and skepticism. These ideas questioned absolute truths, emphasizing individual perception and cultural context in determining reality. Sophists like Protagoras and Gorgias shaped Greek philosophy by promoting critical thinking and subjective knowledge.

Sophist ideas had far-reaching impacts, influencing Socrates and Plato and shaping Western philosophy. Their emphasis on rhetoric and persuasion contributed to the development of public speaking and argumentation techniques, leaving a lasting legacy on political discourse and legal practice in ancient Greece.
