Comment: “Western thought, one might say, has been either platonic or anti-platonic but hardly ever non – platonic.” (Popper) (2009)
The remark comes from Karl Popper‘s The Open Society and Its Enemies (1945), in its first volume, The Spell of Plato, immediately after the admission that the influence (for good or ill) of Plato’s work is immeasurable. It echoes Alfred North Whitehead‘s view (Process and Reality, 1929) that European philosophy is a series of footnotes to Plato. Coming from Plato’s fiercest modern critic, the concession carries weight. It holds for the questions Western thought asks, less for its answers, and less still beyond the West.
Why Plato Set the Terms
Plato framed, in one connected system, the questions later theory keeps returning to: appearance against reality, knowledge against opinion, justice as objective truth or as convention, who should rule (the wise, the many or the law), the ideal against the actual, the individual against the whole, and the politics of property, family, education and gender. Even his opponents were mapped in advance: Thrasymachus voiced justice as the interest of the stronger, Glaucon justice as a contract of the weak.
The Platonic and Anti-Platonic Lines
| Question | Platonic line | Anti-Platonic line |
|---|---|---|
| Source of political truth | Objective Good, known by reason | Experience, consent, material life |
| Who rules | The wise | Law, the people, removable rulers |
| Method | Ideal as standard | Realism, empiricism |
| Heirs | Augustine, Rousseau, Hegel, Strauss | Aristotle, Machiavelli, Hobbes, Marx, Popper |
- Platonic. St. Augustine of Hippo‘s two cities (City of God, 413–426) Christianised the two worlds; Jean-Jacques Rousseau‘s general will and civic education, Georg Wilhelm Friedrich Hegel‘s rational state and Leo Strauss‘s classical natural right extend the claim that politics answers to an objective good. Today’s epistocrats revive the philosopher-ruler.
- Anti-Platonic. Aristotle brought form down into matter and preferred law to the wise man. Niccolò Machiavelli (The Prince, ch. 15) turned from imagined republics to the effectual truth of things. Thomas Hobbes rebuilt justice as covenant, Glaucon’s position restored. Karl Marx inverted idealism. Friedrich Nietzsche called Christianity Platonism for “the people” (Beyond Good and Evil, 1886), and Hannah Arendt (The Human Condition, 1958) faulted Plato for replacing action with making.
- Ambivalent cases prove the rule. Popper indicted Marx beside Plato for historicism, though Marx was a materialist; Arendt held that the tradition had its definite beginning in Plato and Aristotle and ended in Marx (Between Past and Future, 1961). Popper’s own book is anti-Platonic and dominated by Plato.
Is There a Non-Platonic Thought?
- Empirical political science (behaviouralism, systems theory) set out to explain rather than prescribe; yet its fact–value separation is itself a position on Plato’s question.
- John Rawls (“Justice as Fairness: Political not Metaphysical”, 1985) tried to ground justice without any comprehensive doctrine, the most deliberate modern attempt at a non-Platonic politics; critics answer that “reasonableness” smuggles in a good.
- Beyond the West the dictum lapses, as Popper’s own qualifier “Western” concedes. Kautilya‘s Arthashastra and the Confucian classics built statecraft without Forms. When Bhimrao Ramji Ambedkar (Annihilation of Caste, 1936) likened chaturvarnya to Plato’s classes, saying Plato had no perception of the uniqueness of every individual, he joined the anti-Platonic line on Indian ground.
Conclusion
Popper is right about the agenda. Plato posed the question every tradition must answer: is politics a matter of knowledge or of will, of the wise or of law? Even the attempts to be non-Platonic end up answering it, so the dictum survives as a claim about inescapable questions, not about shared answers.
