How Philosophy Became Possible: I. When the World Becomes Questionable

Philosophy is often said to have begun in ancient Greece when people stopped explaining the world through myth and started explaining it through reason.

It is an attractive story.

It is also probably too simple.

The Greeks did not suddenly abandon myth. Their poets continued to tell stories about gods, heroes, origins and destinies. Nor did the earlier cultures of the ancient Near East lack sophisticated forms of observation, calculation, prediction or explanation. The distinction between myth and reason was never as clean as the familiar story suggests.

So perhaps the more interesting question is not:

Why did the Greeks stop believing in myth?

It is:

What changed such that the world could increasingly become something to be questioned?

That is a different question. It does not assume that philosophy began when one kind of explanation was replaced by another. It asks what happened to the possibility of explanation itself.

A world already full of order

The earliest Greek thinkers we associate with philosophy are usually called the Pre-Socratics. Among them, Thales, Anaximander and Anaximenes are conventionally identified with the Milesian school of the sixth century BCE.

Their significance is sometimes presented as a simple movement from supernatural explanation to natural explanation.

Thales supposedly proposed water as the fundamental principle of things. Anaximenes proposed air. Anaximander spoke of the apeiron, the indefinite or boundless.

But the important point is not that they chose different substances.

Something more fundamental was changing.

The world was beginning to be approached as an order whose organisation could itself be investigated.

Instead of asking only which divine powers were responsible for particular events, one could ask what kind of underlying principle might account for the diversity and transformation of things.

Why does the world have the order it has?

How does one thing become another?

What persists through change?

What is the relation between the many things we encounter and whatever makes them a coherent world?

These questions do not yet constitute “philosophy” in the fully developed sense that would emerge later. But they begin to alter the conceptual ecology in which such philosophy could become possible.

The world is no longer merely the setting in which stories happen.

The world itself becomes a question.

From events to relations

This change matters because a question about the world is not simply a request for another fact.

Suppose we observe that the seasons change, rivers flow, plants grow, animals reproduce and storms arise. We can describe each event. We can tell stories about them. We can associate them with particular powers or agencies.

But another possibility emerges when we ask what these phenomena have in common.

What kind of relation connects them?

What principle might account for their different forms?

What remains invariant while things change?

The question begins to move from the individual event toward the relations that make events intelligible.

This is one of the transformations that will recur throughout the history of Greek thought.

A phenomenon can be treated not merely as something that happens, but as an instance of a more general order.

That does not mean the Greeks suddenly discovered “scientific thinking.” The categories themselves were still developing. Rather, the possibility of looking for an intelligible order that was not exhausted by the individual event was becoming increasingly available.

And once that possibility exists, it changes the questions that can be asked next.

The problem of beginnings

An especially revealing question concerns the beginning of the cosmos.

A traditional cosmological story can ask how the gods came to be, how the world was generated, or which divine powers govern it. But the Milesians introduce a different kind of problem.

If the world has an underlying order, what is it?

Anaximander's apeiron is particularly suggestive here. Whatever precisely we should make of the fragmentary evidence, the concept does not simply identify another familiar object within the world. It attempts to think about what could underlie the oppositions and transformations through which the world comes to be what it is.

The difficulty is immediately apparent.

If the principle is itself just another thing, we have not really explained the relation among things. But if it is not a thing in the ordinary sense, how are we to think about it?

The question begins to press against the limits of the conceptual vocabulary available to the questioner.

And this is important.

A new kind of question can create a demand for new kinds of concepts.

The conceptual ecology begins to change recursively.

Philosophy does not arrive from nowhere

This is why it is misleading to imagine philosophy as an isolated invention by a handful of exceptionally clever individuals.

The Greeks inherited an enormous conceptual world.

They inherited cosmologies, religious traditions, agricultural knowledge, astronomical observations, systems of measurement, mathematical techniques, political institutions, poetry, navigation, trade and contact with other cultures.

They also inhabited a social world in which argument, public speech and disagreement could acquire unusual significance.

None of these conditions caused philosophy in any simple sense.

But together they created an ecology in which certain possibilities could become more available.

This is an important distinction.

An affordance does not determine what will be done with it.

A landscape can make some paths easier to discover without dictating which path anyone will take.

The emergence of Greek philosophy may therefore be understood not as the sudden appearance of reason in a previously irrational world, but as a reorganisation of possibilities within an already highly structured conceptual ecology.

The Greeks did not discover that the world was intelligible.

They began, in increasingly explicit ways, to ask what would make its intelligibility possible.

From authority to inquiry

There is another subtle transformation here.

An inherited account can have authority because it has been inherited. It belongs to a tradition, a community and a system of practices that tells people how the world is to be understood.

But once an account can be treated as something that might be questioned, another possibility appears.

It can be compared with another account.

It can be criticised.

It can be required to explain something it previously left unexplained.

It can be asked to account for its own assumptions.

And once this happens, explanation acquires a new kind of vulnerability.

A cosmological account is no longer simply something one receives.

It becomes something one may have to defend.

This does not yet give us the fully articulated argumentative practices of later philosophy. But it creates the conditions in which such practices can develop.

The world becomes questionable.

Then explanations of the world become questionable.

And eventually, perhaps, the very concepts with which we question the world become questionable too.

That trajectory will take us a long way.

The first philosophical possibility

It would be tempting to say that the first Greek philosophers discovered nature.

But nature was already there.

What changed was not the existence of the world but the relation between the inquirer and the world.

The world could now increasingly be approached as something whose order was not simply given in the form of inherited narrative. Its regularities, transformations and principles could become objects of inquiry in their own right.

This is a small change in one sense.

No new planet was discovered.

No new substance suddenly appeared.

Yet conceptually it is enormous.

For once the world becomes questionable, almost anything within it can become questionable too.

What is matter?

What is change?

What is permanence?

What is order?

What is number?

What is motion?

What is being?

And eventually:

What is knowledge?

What is justice?

What is truth?

What is a concept?

The history of Greek philosophy can therefore be read not simply as a sequence of answers to these questions, but as the history of new questions becoming possible.

That may be the deeper significance of the Milesian beginning.

Philosophy did not begin when someone finally possessed the right explanation of the world.

It began when the world itself could become an object of inquiry—when an inherited order could be opened, however tentatively, to questioning.

And once that happens, there is no obvious way to close the question again.

The world has become questionable.

The next problem is more difficult.

If everything we observe is changing, what would it mean for anything to remain the same?

When does change itself become a problem?

That is where Heraclitus and Parmenides will take us.
