What Came Before Philosophy: Greek Mythology, Hesiod & Homer Explained

Key Takeaways

Before philosophy, mythology provided answers to humanity’s deepest questions through imaginative storytelling.
Philosophy was born when thinkers began questioning mythological stories and demanding reason and evidence.
Hesiod’s Theogony describes the origin of the gods and establishes Chaos as the first principle of existence.
Homer’s Iliad illustrates heroic virtues — strength, courage, and moderation — and the nature of Greek gods.
Moderation (balance) is a central moral theme in Homer: without it, even the greatest qualities become destructive.
Mythology and early philosophy were opposed yet deeply connected — philosophers were often shaped by the myths they questioned.

Introduction

Before the first philosophers appeared, ancient Greek culture already had a rich tradition of answers to life’s deepest questions — answers told through mythology. Understanding this mythological background is essential for any student of Western philosophy, because the earliest philosophers were not writing in a vacuum. They were responding to, and were shaped by, the stories, gods, and values that surrounded them. This note explores what came before philosophy, why mythology matters to philosophical history, and what the works of the two most important Greek poets — Hesiod and Homer — tell us about the world that philosophy grew out of.

1. Mythology: The World Before Philosophy

Human beings have always been curious. Questions about identity, origin, death, and the nature of the world have occupied people across all cultures and all ages. Before philosophy, these questions were answered not through reasoned argument but through stories.

How Mythology Developed

Ancient peoples sought answers to fundamental questions: Who are we? Where do we come from? How was the world made? What happens after death?
Their answers took the form of imaginative stories featuring gods, demigods, dragons, and supernatural beings.
These stories were passed from generation to generation and gradually became organised into consistent systems.
We call these organised story-systems mythology — from the Greek mythos (story or narrative) — because they are rooted in imagination rather than evidence.
Myths became foundational: entire cultures, traditions, and civilisations were built upon them, and they shaped the thinking, values, and behaviour of millions of people.

From Mythology to Philosophy

Philosophy was born when certain individuals began to question the myths: Why should we believe these stories? What evidence supports them? What is their logical basis?
This questioning attitude — demanding reason rather than accepting inherited authority — is the defining move that separates philosophical thinking from mythological thinking.
The transition was not peaceful. Philosophers who challenged traditional mythology faced serious social consequences.

Example: Socrates was put on trial in Athens and sentenced to death. The charges against him included questioning the city’s traditional gods and corrupting the minds of the young by encouraging doubt.

Despite their opposition, mythology and early philosophy remained deeply connected. Philosophers who challenged the myths were still shaped by the values, themes, and questions those myths had raised.
The relationship between mythology and philosophy is therefore not simply one of conflict — it is also one of inheritance and influence.

Why Study Mythology Before Philosophy?

Understanding mythology helps us see where the first philosophers were coming from and what problems they were trying to solve.
The themes Greek mythology explored — the origin of the world, the nature of the gods, justice, honour, human virtue — became the first themes of Greek philosophy.
Without this background, the ideas of Thales, Pythagoras, and Socrates are harder to place and understand.

2. Hesiod and the Theogony

Hesiod was one of the earliest and most important Greek poets. Active around the 8th century BCE (approximately 800–700 BCE), he wrote the single most important text of Greek mythology: the Theogony.

What Is the Theogony?

Theogony comes from the Greek words for ‘origin’ or ‘birth of the gods’ — it is literally an account of how the gods came into being.
It is the foundational text of Greek mythology and had a profound influence on Greek culture, literature, and later philosophy.
Hesiod begins the poem by describing how the Muses — goddesses who inspire poets and writers — appeared to him while he was shepherding his lambs and taught him poetry.
He then claims the Muses breathed their sacred voice into him — meaning everything he writes comes from divine authority, not from his own reasoning.

Note: This is a crucial philosophical point. Hesiod validates his account not through argument or evidence, but through appeal to divine authority. This is precisely the kind of reasoning that the first philosophers would later challenge.

The Creation Account in the Theogony

First came Chaos — a formless, undefined being or condition that Hesiod does not explain further. This is his ‘first principle’: the starting point of all existence.
Then came Earth (Gaia), Tartaros (a deep region beneath the earth), and Eros (the god of love, desire, and attraction) — again, without explanation of how or why.
From Chaos came Darkness (Erebus) and Night (Nyx). From Earth came Sky (Ouranos), Mountains, and Sea.
From the union of Earth and Sky were born the twelve Titans — six male gods and six female gods. The youngest and most significant Titan was Kronos.
Earth and Sky also produced three Cyclopes (each with a single eye at the centre of the forehead) and three Hundred-Handers (each with one hundred hands and fifty heads).

The Story of Kronos and Zeus

Sky (Ouranos) hated the Cyclopes and the Hundred-Handers and hid them deep within the Earth, which enraged their mother, Earth.
Earth persuaded her son Kronos to attack his father Sky — an act of violence by a son against his father, a recurring theme in the poem.
Kronos defeated Sky, but Sky cursed him: ‘Your own son will do to you what you did to me.’
To prevent this, Kronos swallowed each of his children at birth. His wife Rhea hid their youngest son Zeus in a cave and tricked Kronos into swallowing a stone wrapped in cloth instead.
Zeus grew up, returned, and waged war against Kronos and all the Titans. After ten years of battle, Zeus defeated them and became the supreme ruler of the gods.

Key Philosophical Points from the Theogony

Authority over argument: Hesiod does not prove or justify his account — he relies entirely on divine authority. The Muses told him, therefore it is true.
Human-like gods: the gods in the Theogony are born, feel anger, jealousy, and fear, take sides, and act from self-interest — just like human beings.
Chaos as first principle: Hesiod’s Chaos is the earliest attempt in Western thought to name a single origin or first cause of everything — a question that would dominate early Greek philosophy.
Recurring themes: violence, justice (dike), and vengeance (nemesis) run throughout the poem, foreshadowing the moral concerns that Greek philosophy would later address through reasoned argument.

3. Homer and the Iliad

Homer was Hesiod’s contemporary — another great Greek poet of the 8th century BCE. He wrote two epic poems, the Iliad and the Odyssey, both of which had an enormous and lasting influence on Greek culture and thought. The Greeks regarded Homer as their greatest teacher, turning to his stories for guidance on morality, human life, and proper conduct. Western philosophy begins, in a very real sense, from the worldview that Homer created.

The Story of the Iliad

The Iliad is set during the Trojan War (approximately 1300–1100 BCE) — a conflict between Greece and the city of Troy.
The cause of the war: Paris, a prince of Troy (son of King Priam), abducted Helen, the wife of Menelaus, the king of Sparta.
Menelaus’s brother Agamemnon, king of Argos, assembled a vast Greek army and launched an assault on Troy to recover Helen.
The greatest warrior in the Greek army was Achilles — universally regarded as the most powerful fighter of his generation. Homer opens the poem with his name.

The Central Conflict: Achilles and Agamemnon

During the war, the Greeks captured a girl and gave her as a prize to Agamemnon. She was the daughter of a priest of the god Apollo.
The priest appealed to Agamemnon to return his daughter; Agamemnon refused. The priest then prayed to Apollo, who struck the Greek army with a devastating plague.
Under pressure, Agamemnon agreed to return the girl but demanded the prize given to Achilles as compensation.
Achilles refused and, furious at the injustice, withdrew from the war and returned to his tent.
Without Achilles, the Greek army began losing. Achilles’ closest friend, Patroclus, put on Achilles’ armour and entered battle disguised as him — restoring Greek morale temporarily.
Patroclus was killed by Hector, the greatest Trojan warrior and brother of Paris.
Grief-stricken and enraged, Achilles returned to the war, killed Hector, and dragged his body behind his chariot back to the Greek camp.
King Priam secretly entered the Greek camp at night and begged Achilles to return his son’s body. Both men wept — Priam for Hector, Achilles for Patroclus — and Achilles agreed. The poem ends here.

Key Philosophical Themes in the Iliad

Moderation (balance) as a central virtue: Achilles had extraordinary strength and courage, but he lacked moderation — sophrosyne — the ability to keep powerful qualities in check.

Illustration: Achilles’ uncontrolled anger caused him to withdraw from battle (harming his own side), allowed Patroclus to die, and led him to dishonour Hector’s body. His greatest qualities became destructive because they were not balanced by restraint.

The heroic ideal: Homer’s vision of the perfect human being combines strength, courage, and cleverness — but only when held together by moderation. This is what the Greeks taught their children.
The nature of the gods: Greek gods in Homer are immortal and far more powerful than humans, but in every other respect they are fully human — they take sides, feel jealousy, anger, and love, and interfere constantly in human affairs.

Example: Apollo sends plague on the Greek army to punish Agamemnon. Achilles’ goddess mother Thetis intercedes with Zeus on her son’s behalf. The gods are not impartial or perfectly just — they are partisan and emotional.

Honour and justice: Homer places honour (time) at the highest level of human value. His concept of justice is that every person must receive the honour they deserve — no more, no less.
Moral order: Homer presents Paris’s abduction of Helen as morally wrong — a violation of the sacred duty of a guest toward his host. Zeus himself is angered by this breach, and Troy’s defeat is presented as a consequence of it.
Gods and humans share a common nature: the only differences Homer identifies between gods and humans are power and immortality. In mind, emotion, motivation, and behaviour, they are essentially alike.

Conclusion

Greek mythology was not mere entertainment — it was the intellectual and moral framework within which an entire civilisation lived and thought. Hesiod’s Theogony raised the question of first origins and established a tradition of cosmic storytelling rooted in divine authority rather than reasoned argument. Homer’s Iliad gave the Greeks their model of the ideal human being — courageous, strong, clever, and above all, moderate. When the first philosophers arrived, they did not create their questions from nothing; they inherited them from this rich mythological tradition and then asked: can we answer these questions through reason instead of stories? That critical shift — from myth to reason — is where Western philosophy begins.

Frequently Asked Questions

What came before philosophy in ancient Greece?

Before philosophy, Greek culture relied on mythology to answer fundamental questions about the world, human existence, and morality. Mythological stories — passed down through generations and eventually recorded by poets like Hesiod and Homer — explained the origins of the world, the nature of the gods, and the proper values of human life. Philosophy emerged when thinkers began questioning these stories and demanding rational justification rather than accepting divine authority.

How did Greek mythology lead to the birth of philosophy?

Philosophy was born out of a critical attitude toward mythology. When thinkers began asking ‘Why should we believe these stories? What is the evidence? What is the reason?’ they made the foundational philosophical move — replacing appeal to authority with a demand for reasoned argument. Socrates is the most famous example of this: he was executed in Athens partly because he questioned the city’s traditional gods and encouraged others to think critically.

What is Hesiod’s Theogony about?

Hesiod’s Theogony, written around the 8th century BCE, is the foundational text of Greek mythology. It describes the origin and genealogy of the Greek gods, beginning with Chaos as the first principle of existence, and proceeding through the births of Earth, Sky, the Titans, and ultimately Zeus. It is philosophically significant because it attempts to give a systematic account of cosmic origins — even if that account rests on divine authority rather than rational argument.

What is the main philosophical lesson of Homer’s Iliad?

The Iliad’s central philosophical lesson is the importance of moderation — the ability to keep one’s strongest qualities in balance. Achilles has unparalleled strength and courage, but without moderation his virtues become destructive: his unchecked anger leads to the death of his friend Patroclus and to his own dishonourable treatment of Hector’s body. Homer’s ideal human being combines strength, courage, and cleverness, but only when these qualities are held together by self-restraint.

What are the Greek gods like in Homer’s Iliad?

In Homer’s Iliad, the gods are essentially human in nature. They experience the same emotions as human beings — anger, jealousy, grief, love — and they take sides in human conflicts based on personal preference. The only qualities that distinguish gods from humans are their superior power and their immortality. This portrayal would later be challenged by philosophers who argued that a true god must be rational, impartial, and morally perfect.

What is the concept of justice in Homer?

In Homer, justice is closely linked to honour. His concept of justice is that every person must receive the honour they deserve — no more and no less. When Paris abducts Helen, he violates a fundamental moral and social duty (the duty of a guest to his host), which angers Zeus and sets in motion the catastrophic events of the Trojan War. Justice, for Homer, is ultimately enforced by the gods, not by human institutions alone.
