Was Plato a Philosopher?

The question I'm posing in this post's title is deliberately provocative. Plato was clearly one of the key figures through whom the Western world learned what philosophy was. I'm well aware of this. I'm aware that asking whether Plato was a philosopher can sound rather like asking whether Shakespeare was a playwright.

But there is a serious question hidden inside the apparent churlish question. Plato was certainly a philosopher, and one of the greatest. Yet I'd like to suggest he was a very different kind of philosopher from most of those who came after him, and especially from the figure we are likely to encounter today in the philosophy department of a modern university. And, for me, this is an important point.

Plato wrote no treatises or tracts or even essays. He never set out a philosophical system in his own voice. He did not define his terms, announce his thesis and proceed through a sequence of propositions towards a conclusion. He left us no work entitled On Justice, The Nature of Knowledge or A Theory of Reality.

Instead, he wrote dialogues. Dramatic dialogues.

More than thirty years ago, I went to Oxford intending to write a doctoral thesis about this peculiarity. I was interested in the fact that the founding figure of Western philosophy had declined to write in the form that philosophy later came to regard as its own. Why had Plato created dramatic conversations rather than clear arguments encased in treatises? Why had he populated them with carefully drawn characters and placed them in particular dramatic settings? Why did he use myth, metaphor, irony and indirection so extensively? Why did he so conspicuously refuse to speak in his own voice?

At the time, these questions seemed both relevant and strangely neglected. The dominant approach in Oxford was to regard the dialogues as containers for philosophical arguments. The real work consisted in getting behind the dramatic presentation and identifying Plato’s doctrines. On this view, Socrates could usually be treated as Plato’s "mouthpiece". Character and setting might add historical interest or literary colour, but the philosophy itself lay in the arguments that could be extracted from the dialogue and reconstructed independently.

I found this difficult to accept. In fact, I found it critically naive. Plato struck me as too deliberate a writer for the form of his work to be treated as packaging. If he had wanted to write treatises, he could have done so. If he had wanted to state his conclusions directly, nothing prevented him. The fact that he repeatedly chose not to seemed philosophically significant.

My suspicion was that the dialogues did not simply contain philosophy. They showed philosophy in action. Their characters, settings, hesitations, digressions and failures were not literary ornament applied to a body of ideas that existed independently of them. They were part of the thinking.

I was not yet capable of making that case well. My Greek was not strong enough, my philosophical training was uneven and I lacked the confidence and academic fluency required to turn an intuition and a conviction into a persuasive scholarly argument. In the end I lost confidence that my project was worth completing. After three difficult years, I left Oxford and abandoned the thesis. (The personal story behind my time at Oxford is in my second post)

But I never quite abandoned the question. It followed me into educational publishing, into work on organisational change and into my continuing interest in metaphor, interpretation, judgment and the limits of abstract systems. More recently, discussions of artificial intelligence and the tendency to understand the human mind as an information-processing machine have brought many of these concerns back together.

Returning to Plato now, I can see that the question I was trying to ask was not simply about literary form. It was about what philosophy is, and about the difference between telling people what is true and enabling them to see.

Telling and showing

Most philosophical writing tells. The philosopher states a position, defines the relevant concepts and gives reasons for accepting the conclusion. The reader’s task is to follow the argument and decide whether it succeeds. Plato certainly does this too. His dialogues contain intricate arguments, precise distinctions and some of the most influential lines of reasoning in the history of thought. It would be a serious mistake to turn him into an opponent of logic or analytical clarity.

But argument is only part of what he is doing.

Plato seems to have understood that philosophical argument, while necessary, is not sufficient. A person may follow an argument, even agree with its conclusion, without undergoing any significant change in how he sees or lives. We are all familiar with truths that we can state perfectly well but which have little effect upon us.

We know that wealth does not guarantee happiness and continue to organise our lives around accumulating it. Organisations proclaim the importance of learning while maintaining systems that punish experiment and failure. Schools talk about understanding but reward the reproduction of information. The proposition has been heard. It has not altered perception.

Plato’s difficulty was not simply that people lacked the correct conclusions. It was that they were attached to inadequate ways of seeing. They mistook convention for nature, prestige for wisdom, persuasion for knowledge and familiarity for truth. A person could be highly informed and still badly oriented.

If this is the problem, then telling people the answer will not be enough. New information can be absorbed into the very framework that needs to be questioned. The person must learn to notice differently. What appears important must change. What once seemed obvious must become strange.

This helps explain why Plato did not simply tell the world his philosophical conclusions. He understood that philosophical communication was not a matter of moving ideas efficiently from one mind to another. It was closer to education in the deeper sense: the formation of a person capable of seeing what the argument meant. The dialogues show that formation taking place, or failing to take place.

Philosophy in action

There is a familiar way of reading Plato that separates the philosophical content from the form in which it appears. The dialogues are acknowledged to be beautifully written. Their settings make abstract arguments memorable, and their characters give us some sense of Socrates as a living presence. Once these literary qualities have been appreciated, however, the serious task begins. We identify the argument and disentangle it from the dramatic presentation.

This approach is understandable. We can reconstruct an account of justice from the Republic, an argument about knowledge from the Theaetetus or a theory of love from the Symposium. Philosophy depends partly upon our ability to distinguish premises from conclusions and ask whether an argument succeeds. The mistake is not to analyse Plato’s arguments. The mistake is to assume that the argument can be fully understood once everything dramatic has been stripped away.

Consider the Symposium. It is possible to extract from the speech Socrates attributes to Diotima an account of desire as an ascent from attachment to particular beautiful bodies towards an apprehension of beauty itself. But the speech does not occur in a philosophical vacuum. It is delivered at a drinking party, after a succession of contributions from men whose own desires, vanities and relationships form part of the drama. Then Alcibiades arrives, drunk and uninvited, and speaks not about love in general but about his own fascination with Socrates. Alcibiades does not merely add another theory. He shows us something the preceding speeches have not contained. His appearance brings the discussion of love into contact with jealousy, humiliation, erotic obsession, vanity and failed self-knowledge. The philosophical ascent described by Diotima is followed by the arrival of a man who has recognised something extraordinary in Socrates and nevertheless remained incapable of changing his life. The order matters. The character matters. The interruption matters.

The same is true of the Phaedo. Its arguments about the soul are spoken by a man awaiting execution. Socrates’ friends are not participating in a detached seminar about personal identity. They are trying to understand how he can remain composed in the face of death and whether the arguments he offers justify that composure. The setting is not background atmosphere. It changes what the argument means.

Throughout the dialogues, Plato places arguments in human beings. A conversation about courage with celebrated soldiers is not simply an exercise in definition. Their inability to explain the virtue for which they are admired becomes part of the inquiry. A discussion of rhetoric with ambitious political figures is not merely about persuasion. Their ambitions and moral character reveal what is at stake.

Plato does not merely tell us what philosophy is. He shows Socratic logos at work: questioning, probing, adapting, exposing contradictions and unsettling confidence. We see what happens when argument comes into contact with vanity, desire, fear and ambition. This is philosophy as activity rather than doctrine. The dialogue form enables Plato to show reasoning taking place between people, under pressure, in circumstances where the outcome matters.

Plato and Shakespeare

The comparison that increasingly seems useful to me is with Shakespeare. We do not normally approach King Lear in order to establish Shakespeare’s theory of authority, ageing or filial obligation. Nor do we read Macbeth mainly to identify his doctrine of ambition. Shakespeare must have held views about power, love, death, loyalty and self-deception, but he did not understand his task as explaining those views to us.

He created dramas in which we could encounter them.

Shakespeare shows Othello’s jealousy. He does not give us a definition of jealousy and then use Othello as an illustration. He creates a world in which jealousy grows through insecurity, imagination, manipulation, misplaced trust and the desire for certainty. We understand jealousy by watching what it does to a person and to the world around him.

The same is true of Lear’s blindness or Macbeth’s ambition. Shakespeare does not tell us what these things are from outside. He enables us to see them in action.

That kind of seeing is a form of understanding. It is not inferior to conceptual knowledge, though it is different from it. A definition may be accurate while leaving us untouched. A drama can alter what we recognise in the world and in ourselves.

Now, I'm well aware tht Plato’s dialogues are not Shakespearean plays. They are explicitly argumentative in a way Shakespeare’s tragedies are not. But my point is that Plato was probably closer to Shakespeare than the standard image of the philosopher allows us to recognise.

Where Shakespeare shows jealousy, pride or ambition in action, Plato shows philosophy in action. More precisely, he shows Socratic logos: argument as a living encounter between people rather than a finished structure presented by an author.

This is why the common description of Socrates as Plato’s mouthpiece has always seemed inadequate to me. A mouthpiece conveys the views of an absent authority. Socrates does something much more complicated. He adapts to different interlocutors. He provokes, flatters, ironises, unsettles and sometimes appears to fail. The same words addressed to another person in another setting would not mean the same thing.

To read Plato only for the views expressed by Socrates is rather like reading Shakespeare in order to establish which character speaks for Shakespeare. The question may occasionally be useful, but it can also misunderstand the work. Shakespeare is not absent because he has nothing to say. He is present in the construction of the whole. In my reading Plato is present in something like the same way.

Plato among the poets

The comparison complicates the familiar story about the birth of philosophy. Plato is often presented as a decisive figure in the transition from mythos to logos: from myth and poetry to reasoned argument. He criticises Homer and the tragedians. In the Republic, he famously excludes much poetry from the ideal city. Philosophy, on this account, establishes itself by rejecting the authority of the poets.

There is truth in that story, but it is too neat. Plato attacks poetry while writing some of the most poetic works in the philosophical tradition. He distrusts myth while inventing myths of extraordinary power. He challenges drama while constructing dramas of his own.He does not simply leave the older literary tradition behind. He absorbs and transforms it.

The early Greek poets and tragedians did not generally offer theories of human life in the modern sense. They staged conflicts among values. They showed people acting under conditions of uncertainty, exposed to luck, fate, error and forces they could not control. Their audiences encountered courage, loyalty, pride, revenge and suffering in action. Greek tragedy did not solve the mystery of human existence. It gave it form. Plato inherited this world even as he challenged it. He recognised the power of reasoned argument, but he also understood that human beings do not live by argument alone. We inhabit images, stories, practices and relationships before we formulate theories about them.

This is why Plato was drawn to drama and myth. He needed forms capable of doing more than stating conclusions. He needed to show movement, resistance, confusion, recognition and failure. He needed to present philosophy not merely as something thought, but as something done.

In this sense Plato is as much a dramatic poet as a philosopher, at least if by philosopher we mean the modern academic figure whose primary task is to articulate and defend propositions. He stands at the beginning of the philosophical tradition, but also remains close to the older world of poetry, tragedy and myth.

Aristotle wrote treatises. Descartes established a method. Kant constructed a critical system. Plato created philosophical works that must be entered rather than merely decoded.

Education as turning

The Allegory of the Cave offers Plato’s clearest account of why telling is not enough.

The prisoners have been chained since childhood. They face a wall and see shadows cast by objects passing before a fire behind them. Because the shadows are all they have ever known, they take them to be reality.

Their problem is not simply that they lack information. They may know a great deal about the shadows. They may identify patterns, make predictions and admire those who are most skilled at interpreting what appears on the wall. Their difficulty is that the whole field within which they understand reality is distorted.

When one prisoner is released, he is not simply given an explanation. He is forced to turn around. The movement is painful. The fire dazzles him. The objects responsible for the shadows initially appear less real than the shadows because they are unfamiliar and difficult to see. When he is dragged out of the cave, the sunlight is almost unbearable.

The allegory is often reduced to a proposition: appearances can deceive us; education leads us towards truth. That is not wrong, but it scarcely captures what Plato has constructed. The prisoner’s education involves disorientation, resistance and loss. What had seemed obvious becomes uncertain. What had conferred status inside the cave may count for nothing outside it. The journey changes not only what the prisoner knows but where he belongs.

Plato describes education as a turning of the soul. The capacity for sight already exists, but it is directed towards the wrong objects. The whole person must be reoriented.

This is why seeing is central. The prisoner does not merely acquire a better proposition about reality. He comes to see differently. His education is a transformation in what appears real, important and worthy of attention. That kind of change requires formation. It cannot be achieved by explanation (or information) alone. Philosophical argument can challenge, expose and guide, but the learner must undergo the turning. The truth cannot simply be deposited in him.

The cave itself enacts this understanding. Plato could have told us that education involves a transformation of perspective. Instead, he gives us an image of chains, shadows, fire, pain and sunlight. The image continues to work because it makes the structure of misrecognition visible.

Once the cave has entered the imagination, we begin to see caves elsewhere: in political ideology, professional cultures, advertising, social media and inherited assumptions. We may begin, less comfortably, to recognise them in ourselves. Plato does not simply tell us that we may be deceived. He gives us a way of seeing deception.

The value of perplexity

Many Platonic dialogues end without a satisfactory answer. A question is raised, definitions are offered, Socrates reveals their inadequacy and the discussion concludes in uncertainty. If Plato’s purpose were simply to transmit doctrine, this would be a strange way to proceed. The Greek word aporia names the condition into which these conversations often lead: perplexity, puzzlement, the loss of an apparent path forward. Modern education usually treats confusion as a difficulty to be resolved. Plato sometimes treats it as an achievement. The person who is confidently mistaken cannot inquire. His apparent knowledge has closed the question before it has properly opened. Socratic questioning loosens the hold of what had seemed self-evident. It does not necessarily produce knowledge, but it creates the conditions in which learning might begin.

Here again, Plato shows rather than merely tells. He does not write a treatise explaining that intellectual humility is important. He constructs encounters in which confident people discover that they do not understand what they thought they understood.

The reader is drawn into the same experience. We may agree with a definition that Socrates then dismantles. We may become impatient with an interlocutor only to realise that our own answer would have been no better. Because Plato does not step forward to explain the meaning of every exchange, we must judge for ourselves. The author’s absence is therefore not a literary eccentricity. It is part of the educational design. Plato refuses to do all the work for us because the work of judgment cannot be transferred.

Philosophy begins not in the possession of an answer, but in the moment when the familiar answer no longer satisfies.

Metaphor and perception

Plato’s use of metaphor belongs to the same understanding of education.

The cave, the divided line, the charioteer, the ship of state and the ring of Gyges do not merely illustrate arguments completed elsewhere. They organise perception. They allow relationships among knowledge, desire, power, education and character to become visible.

Modern work on metaphor has shown how deeply metaphors structure thought. We spend time, defend positions, climb career ladders, process information and manage human resources. When an organisation is understood as a machine, we notice efficiency and control but may overlook tacit knowledge, emotion and improvisation. When the mind is understood as a computer, we notice processing and retrieval but may neglect embodiment, judgment and lived meaning.

The danger is not that metaphor distorts a world we might otherwise grasp literally. We cannot think without metaphor. The danger begins when a metaphor becomes so familiar that we no longer recognise it as one.

Plato understood that people inhabit imaginative structures before they articulate theories. To change how they think, one may first have to change what they can see.

This is why his myths and metaphors are not detachable ornaments. They are instruments of formation. The cave does not merely make an argument more memorable. It gives the reader a structure through which reality can be reinterpreted.

A proposition tells. A metaphor can continue to show.

Plato in the age of AI

These questions matter now because contemporary culture increasingly describes knowledge, language and intelligence in computational terms.

Large language models can summarise books, reconstruct arguments, define concepts, draft essays and generate fluent explanations. Their abilities are extraordinary. At the same time, our understanding of these systems often begins from a definition of thinking that goes largely unexamined.

If intelligence is information processing, then a system capable of processing immense quantities of information appears self-evidently intelligent. If writing is the arrangement of words to convey ideas, a system capable of producing clear prose appears to be doing what writers do. If education is the delivery of personalised content, AI may appear capable of replacing much of the teacher’s role.

Plato encourages us to examine the metaphor before accepting the conclusion. What if understanding involves more than possessing accurate representations? What if it includes a reorientation of attention, a growing sensitivity to what matters and an ability to judge what a situation requires? What if meaning arises through participation in practices, relationships, histories and forms of life rather than solely through the manipulation of symbols?

These questions do not justify an easy dismissal of machine intelligence. AI can expose assumptions, generate alternative perspectives and help people articulate ideas they have struggled to express. This essay itself has developed partly through an extended dialogue with AI. The technology has helped me retrieve material, test formulations and see connections.

Yet the experience also clarifies a distinction. Producing a plausible interpretation is not the same as understanding what that interpretation means within a life. A model may generate an account of the cave. It does not encounter the image as a person might whose assumptions about education, authority or reality have been unsettled by it.

Human understanding is bound up with the fact that something is at stake for us. We occupy situations, inherit histories, make commitments and live with the consequences of judgment. AI is extraordinarily powerful within an instrumental frame: it can organise, compare, calculate, summarise and optimise. Plato’s dialogues point towards another dimension of intelligence—the capacity to question the purposes themselves and to become differently oriented towards them.

A dialogue in the Platonic sense does not simply move efficiently towards an answer. It may alter the question, expose the inadequacy of the original aim or change the person who asked it. This is the distinction between producing a conclusion and undergoing an education.

What kind of philosopher was Plato?

So, was Plato a philosopher? Of course he was. But the apparent absurdity of the question exposes how much the meaning of the word has changed. The modern academic philosopher is usually identified by a recognisable set of activities: analysing concepts, constructing arguments, responding to specialist literature and publishing claims that can be scrutinised by other specialists. This work can be exceptionally demanding and valuable.

But the Greek word points towards something broader and less secure: the love of wisdom. It suggests not the possession of wisdom, but a life oriented towards it.

Plato belongs to this older conception. He did not regard philosophy primarily as a body of conclusions to be communicated. It was an activity: a disciplined turning towards reality and a testing of the assumptions by which one lived. A treatise tells us where its author has arrived. Plato wanted to show something of the journey. This required arguments, but also characters, situations, myths, failures and silences. It required an author who would not settle every question in advance and readers who could not simply extract the correct view and move on.

Plato understood that reason does not operate in isolation. It is entangled with desire, status, ambition, fear and self-image. A person may reject an argument because it is weak, but also because accepting it would threaten the life he has constructed. The dialogue makes these entanglements visible. This is not a retreat from truth or argument. It is a more sophisticated understanding of what argument can and cannot do. Argument is necessary because philosophy requires reasons. It is insufficient because reasons must be seen, absorbed and related to a life.

Plato did not merely want to tell his readers what to think. He wanted to form the kind of readers who might become capable of seeing for themselves.The familiar Plato is the architect of a metaphysical system: the thinker who divided reality into appearance and truth, body and soul, opinion and knowledge. That Plato may exist. But there is another Plato in the dialogues: elusive, dramatic, ironic and unwilling to separate philosophy from the education of perception.

This Plato stands partly in the lineage of Homer, Sophocles and the older literary tradition, as well as in the lineage of Aristotle, Descartes and Kant. He is not merely a philosopher who happened to write well. He is a philosophical dramatist whose choice of form expresses his understanding of philosophy. Like Shakespeare, Plato created works that have to be entered rather than merely decoded. Their meaning changes as the reader changes because they do not simply contain information. They show human beings thinking, resisting, misunderstanding and sometimes beginning to see.

They stage the activity of understanding.

Returning to the question

It has taken me more than thirty years to understand the question I thought I was asking when I went to Oxford. At the time, I believed I was making a scholarly argument about dialogue form. I wanted to show that character, setting and dramatic structure were philosophically significant, and that Socrates should not be treated as a transparent vehicle for Plato’s doctrines.

I still believe that. But I can now see that the issue was larger. It concerned the relationship between telling and showing, between knowledge and formation, between philosophy as the communication of conclusions and philosophy as a change in vision. It concerned why some truths can be stated clearly and leave us untouched, while a story, an image or an encounter may continue working upon us for years.

While I was at Oxford, I lacked the resources to articulate that argument then. The years outside academia, which once seemed like a departure from the work, have become part of the route back to it. Educational publishing, organisational life, technological change and reading across disciplines have altered the horizon from which I now encounter Plato.

Plato has not changed, but I have, and because I have changed, the question has changed too. I once thought I was defending the dialogue form against philosophers who wanted to extract the argument. I now see Plato’s writing as part of a broader challenge to the way modern culture imagines knowledge, education, intelligence and philosophy itself.

We are drawn towards forms that promise frictionless transmission: the concise explanation, the efficient presentation, the argument stripped of ambiguity, the correct answer delivered on demand. These forms are useful, sometimes indispensable. But Plato reminds us that the most important kinds of understanding may involve difficulty, interruption and the loss of certainty.

Was Plato a philosopher? Yes. But I think he was a philosopher in a sense we have partly forgotten. He understood that telling people the truth is not the same as enabling them to see it. That is why he did not simply explain philosophy. He showed it happening.

Part Two will turn from Plato to the people and institutions through whom I first encountered him: an almost unknown teacher in Dublin who seemed to embody philosophy as the love of wisdom, and some of the most celebrated philosophers in Oxford, whose brilliance forced me to ask whether cleverness and wisdom are quite the same thing.
