Critiques of Plato: From Totalitarianism to Idealism

Few thinkers have shaped Western political philosophy as deeply as Plato, yet few have attracted such fierce criticism. His Republic imagines an ideal state ruled by philosopher-kings, governed by wisdom rather than popular vote, and held together by communal living among its guardians. For centuries, students have admired this vision as a noble pursuit of justice. But not everyone has been convinced. From his own pupil Aristotle to twentieth-century philosophers like Karl Popper, critics have argued that Plato’s perfect state is impractical, oppressive, and even dangerous. Understanding these critiques is essential, because they reveal both the brilliance and the blind spots of one of history’s greatest minds.

Karl Popper: Plato as an enemy of the open society 🔗

The most famous and damaging attack on Plato came from Karl Popper, the Austrian-British philosopher who fled the rise of Nazism in Europe. In his two-volume work The Open Society and Its Enemies, published in 1945, Popper traced the intellectual roots of modern totalitarianism back through history. He argued that Plato was the philosophical champion of the “closed society” and that his ideas laid the groundwork for the authoritarian regimes of the twentieth century.

Popper wrote the book during the Second World War and described it as his personal “war effort.” He believed that fascism and Stalinism were not entirely new inventions, but the latest expressions of an ancient way of thinking. According to Popper, totalitarian ideas are as old as civilisation itself, and a close reading of the Republic reveals what he saw as Plato’s deeply illiberal leanings.

Popper’s interpretation of Plato’s totalitarianism 🔗

What exactly did Popper find so troubling? His objections centred on a few key ideas. First, he criticised historicism – the belief that history follows fixed laws that allow us to predict and control the future. Plato, in Popper’s reading, was driven by a fear of change. The decline of the stable, hierarchical societies of the past into messy Athenian democracy filled Plato with anxiety, and his solution was to build a state where all social change would be permanently arrested.

Second, Popper objected to the idea of the philosopher-king. He argued that a ruler who possesses absolute knowledge becomes immune to criticism and therefore unaccountable, which inevitably leads to tyranny. For Popper, the central question of politics was never “who should rule?” but rather “how can we design institutions that allow us to remove bad rulers without bloodshed?” Plato’s system offered no answer to this, because it placed an unchallengeable elite at the top.

Popper also believed that Plato betrayed the spirit of his own teacher. He drew a sharp line between Socrates, whom he admired as humane and democratic, and Plato, whom he saw as having turned away from the open and critical temper of his mentor. In Popper’s view, Plato transformed philosophy from a tool for questioning authority into an instrument for enforcing it.

Aristotle: the practical critic 🔗

Long before Popper, Plato faced criticism from much closer to home. Aristotle, who studied under Plato for nearly twenty years at the Academy, became his most important early critic. In Book II of his Politics, Aristotle directly examined the proposals of the Republic and found many of them deeply flawed.

The disagreement between teacher and student reflects two very different temperaments. Plato was a radical idealist, willing to propose extreme solutions to achieve a perfect society. Aristotle was a pragmatist who preferred to work with human nature as it actually is. Rather than dreaming of the “best state,” Aristotle focused on the “best practicable state” – one that could realistically function given the limitations of real people.

The critique of communism of property 🔗

Plato proposed that the guardians of his ideal state should own no private property and share their possessions in common. The idea was to eliminate greed, corruption, and selfish interest among the rulers. Aristotle found this both unworkable and counterproductive.

His most memorable objection was that what is common to the greatest number gets the least care. People naturally look after what belongs to them and neglect what belongs to everyone. When responsibility is shared among too many, no individual feels personally accountable, and the common property is left to decay. Aristotle also believed that private property serves positive purposes. It gives people motivation, a sense of achievement, and the opportunity to practise generosity. To abolish it, he suggested, would be a remedy worse than the disease.

The critique of communism of wives and children 🔗

Plato went even further, proposing that the guardian class should hold wives and children in common, so that no parent would know which child was their own. The intention was to extend family loyalty to the whole community and prevent rulers from favouring their own kin. Aristotle argued that this would have the opposite effect. Rather than making everyone care for all children, it would destroy natural affection and leave children cared for by no one in particular.

Behind these specific objections lay a deeper philosophical disagreement about unity. Plato sought to make the state as unified as possible, almost like a single person. Aristotle countered that a state is by nature a plurality, and that real unity must be made up of elements that differ in kind. A community of identical people would not be a true city at all, but something more like a military alliance. For Aristotle, differentiation of function was a law of nature, and political philosophers should not try to erase what cannot be erased.

Modern critics: Crossman, Fite, and Russell 🔗

The twentieth century, scarred by the rise of fascism and communism, brought a wave of fresh hostility towards Plato. Several scholars revisited the Republic and saw in it the seeds of the very ideologies threatening the world around them.

R.H.S. Crossman: questioning Plato’s relevance 🔗

Richard Crossman, a British politician and classical scholar, wrote Plato Today in 1937. The book was a bold attempt to imagine how Plato might respond to the politics of the modern world. Crossman was himself a democrat and a socialist, and his purpose was partly to warn his readers against dismissing totalitarian philosophy too easily.

Yet his verdict on Plato was harsh. Crossman concluded that the perfect government Plato described would, in modern terms, amount to a polite form of fascism. He described Plato as a reactionary thinker opposed to the principles of the liberal creed. Famously, Crossman ended by declaring that it is Socrates, not Plato, whom the modern world needs – drawing the same distinction between the questioning teacher and the authoritarian pupil that Popper would later make.

W. Fite: the dangers of idealism 🔗

The American philosopher Warner Fite was another sharp critic. In his book The Platonic Legend, Fite challenged the reverent image of Plato that had dominated scholarship for generations. He argued that admirers had wrapped Plato in a flattering myth, ignoring the troubling implications of his actual proposals.

Fite’s concern was the danger hidden within idealism itself. A philosophy that aims at an absolute, fixed ideal of the good tends to justify forcing real human beings into that mould, regardless of their own wishes. The rigid class structure of the Republic, the censorship of art and poetry, and the use of the “noble lie” to keep citizens in their place all struck Fite as deeply illiberal. Along with Crossman, Fite belonged to a group of interpreters who emphasised the fascist elements in Plato’s thought.

Bertrand Russell on the noble lie 🔗

The philosopher Bertrand Russell added his voice to this chorus. He was especially disturbed by Plato’s willingness to use deception for political ends. The “noble lie” – a founding myth told to citizens to make them accept their social roles – seemed to Russell a dangerous principle. Once rulers are permitted to lie to their people for supposedly good reasons, the door opens to manipulation and tyranny. Russell, like Crossman, saw in Plato’s thought a strong likeness to the propaganda methods of the dictatorships of his own era.

In defence of Plato 🔗

Despite the force of these attacks, Plato has never been without defenders, and many scholars believe his critics went too far. The most spirited defence came from Ronald Levinson, whose 1953 book In Defense of Plato systematically challenged Popper’s reading point by point.

Defenders make several important arguments. First, they point out that the “communism” of the Republic applies only to the small guardian class, not to the whole of society – a limitation that critics often blur. Second, many classical scholars regard Popper’s scholarship as careless, accusing him of quoting selectively and reading modern fears back into an ancient text. Third, defenders argue that the Republic was never meant as a literal political blueprint. Instead, the ideal city is a device for exploring the nature of justice in the individual soul. On this reading, Plato’s communal arrangements are an ethical ideal intended to eliminate conflicts of interest, not a programme for real-world dictatorship.

It is also worth remembering the historical context. Plato wrote in the aftermath of Athens’ defeat by Sparta and the execution of his beloved teacher Socrates by the Athenian democracy. His distrust of popular rule was rooted in painful experience, not abstract cruelty. Judging him by the standards of modern liberal democracy may be anachronistic.

Why these critiques still matter 🔗

The debate over Plato is more than an academic quarrel about an ancient text. It raises questions that remain urgent today. How much should we trust experts to govern us? Is it wise to pursue a perfect society, or does the quest for perfection itself invite oppression? Should the state shape the beliefs of its citizens, even for their own good?

Each critic highlights a genuine tension in Plato’s thought. Aristotle exposes the gap between idealism and practical human nature. Popper warns of the danger in any philosophy that claims certain knowledge of the good and refuses to allow dissent. Crossman, Fite, and Russell remind us that noble intentions can mask authoritarian outcomes. Taken together, these critiques do not destroy Plato’s reputation so much as deepen our engagement with him. The very fact that thinkers across 2,400 years have felt compelled to argue with the Republic is the strongest proof of its lasting power.

What do you think? Is Plato’s vision of rule by the wisest a noble ideal worth striving for, or an inherently dangerous one that sacrifices freedom for unity? And when a philosopher writes about an “ideal” state, should we read it as a literal plan to be built, or as a thought experiment meant to provoke deeper questions about justice?
