Gorgias's Three Arguments Against Existence and Knowledge

Gorgias's Three Pillars of Radical Skepticism

Gorgias, the Sophist, is renowned as a radical skeptic who proposed a powerful argument, sometimes considered rhetorical, challenging fundamental philosophical assumptions. His argument aims to establish three central claims:

1. Nothing exists (Metaphysical Skepticism).
2. If something existed, it would be impossible to know (Epistemological Skepticism).
3. If it were possible to know, it would be incommunicable (Communication Skepticism).

This extreme form of skepticism operates on metaphysical, epistemological, and communicative levels. Gorgias often employs the method of reductio ad absurdum (the test for the absurd) or uses dilemmas to demonstrate the impossibility of the opposing view. The argument is so extreme that some scholars refer to it as a 'dilemma twister'.

First Argument: Nothing Exists (Metaphysical Skepticism)

Gorgias argues that Being (existence) cannot exist because the concept is inherently inconsistent. He states: If something exists, it must either be uncreated (eternal) or created (generated), or both simultaneously. The possibility of simultaneous creation and eternity is immediately discarded.

Analyzing the Origin of Existence

If Being exists, there are three possibilities:

• It was generated (created).
• It is eternal and everlasting.
• It is created simultaneously (ruled out).

If something was created, it had to have been created by something preceding it. This 'something' must have come either from Non-Being (nothing) or from Being. Creation from Non-Being is impossible, as nothing can breed anything. If it came from Being, we face the same dilemma: was that original Being created or eternal? Gorgias is compelled to dismiss both possibilities to avoid falling into a vicious infinite regress. Thus, existence itself is untenable.

Second Argument: Knowledge is Impossible (Epistemological Skepticism)

Even if existence were possible, Gorgias argues that it could not be known. This claim is debatable and has been widely criticized because it challenges widespread assumptions about perception and thought.

The Separation of Thought and Reality

Gorgias suggests that what we think does not necessarily exist. For example, we can think of absurdities that clearly do not exist. This part of the argument generalizes too broadly. However, if we assume that what we think does not exist, then if Being existed, it would not be thought.

In conclusion: If Being exists, there is no thought of it; therefore, it is not possible to think of something that exists. Thought and reality are fundamentally separate.

Third Argument: Communication is Impossible

If something were known, the word used to describe it would be incommunicable. Language only transmits sound, not the actual reality, texture, smells, or images of the object. You cannot transmit a reality itself; you can only transmit sounds (words).

The word is merely a symbol, separate from the thing it represents, making true, direct communication of knowledge impossible.

Summary of Gorgias's Skeptical Framework

The first argument discusses the possibility of existence (metaphysics). The second discusses the possibility of thinking and knowing reality (epistemology) – the core of skeptical thought. The third, often considered the most loose, asserts that human communication is fundamentally flawed.
