Sophist Philosophy: Relativism, Truth, and Social Ethics

The Sophists: Knowledge, Truth, and Social Laws

The thought of the Sophists emerged as a response to the perceived failure of the Presocratic physicists, who were unable to explain physis (nature) through logos (reason). Consequently, the Sophists shifted their focus to the human world (microcosm), as knowledge of the physical world (macrocosm) appeared unattainable.

Protagoras and the Subjectivity of Truth

According to Protagoras, humans subjectivize reality to comprehend it. Therefore, accepting a universal criterion of truth is impossible. We can only speak of truth in relative terms; however, the term is misleading, and it is preferable to use the concept of certainty.

Gorgias and the Power of Language

Gorgias rejected the standard of absolute truth. For him, language creates reality, implying that only what can be stated truly exists.

Social Validity, Laws, and Ethics

The Sophists analyzed the foundations of social laws, morals, and values, concluding that they are often shaped by the interests of the powerful:

• Callicles: Argued that rules were established by the weak to restrain the strong out of fear.
• Hippias and Antiphon: Defended the natural equality of all human beings, regardless of origin.
• Critias: Suggested that gods were invented to enforce social norms, rather than humans being created by divine beings.

Socrates: Challenging Sophist Relativism

Socrates argued that universal truths exist and are inherent to the human soul. He believed that if Protagoras were correct—that man is the measure of all things—then values like beauty, justice, and goodness would be entirely subjective, rendering human understanding impossible.

The Socratic Pursuit of Universal Standards

Socrates rejected relativism, asserting that through rigorous thought, we can reach objective truths. He maintained that Truth, Goodness, Justice, and Beauty are the foundations of society. Philosophy, therefore, must define these concepts to overcome individualism and confusion.

Moral Intellectualism and Virtue

Socrates proposed that error and evil are products of ignorance. This doctrine, known as moral intellectualism, identifies virtue (arete) with knowledge. He argued that virtue is a logical process: those who possess true knowledge and are not dominated by passions will inevitably choose the best course of action.
