Introduction

Do great men make history, or does history produce great men?

This is one of the oldest debates in historiography. Ancient sources give contradictory answers:

  • Plutarch writes biographies because he believes character determines outcomes. A man's virtue or vice shapes his decisions, and his decisions shape events.

  • Thucydides analyzes structural forces because he believes circumstances constrain choice. Athens and Sparta went to war not because individuals chose it, but because fear of Athenian power made war inevitable.

  • Homer presents a world where fate is fixed but choices still matter. Achilles knows he will die at Troy, yet he chooses to fight. Hector knows he will lose to Ach

illes, yet he faces him.

This essay examines the tension between individual agency and structural determinism in ancient thought. The answer matters because how we explain the past shapes how we act in the present. If history is made by great men, we should study leadership, character, and moral choices. If history is made by impersonal forces, we should study economics, demographics, and power structures.

The ancient world offers a more nuanced view: both matter, and the balance shifts depending on context.

I. Plutarch's Vision: Character as Destiny

The Purpose of Biography

Plutarch opens his Life of Alexander with a methodological statement:

"I am writing biography, not history. The most glorious exploits often do not reveal a man's virtue or vice. Sometimes a small thing, a casual remark, or a jest reveals character better than battles where thousands die."

For Plutarch, character is the independent variable. A man's virtues (courage, wisdom, self-control) or vices (ambition, cruelty, cowardice) determine his decisions. His decisions determine outcomes.

History is the cumulative result of individual moral choices.

Case Study: Pericles

Plutarch's Life of Pericles demonstrates the "great man" theory in action.

Pericles' Character:

  • Composed and rational
  • Persuasive without demagoguery
  • Incorruptible (rejected bribes, lived modestly)
  • Strategically patient

Result: Athens flourished under his leadership. The democracy was stable. The strategy against Sparta was sound. Art, philosophy, and architecture thrived.

Plutarch concludes:

"The name was democracy, but the reality was rule by the first man."

Athens functioned well because Pericles held it together. His character — his rationality, his persuasive skill, his strategic discipline — was the difference between Athenian greatness and Athenian chaos.

After Pericles died (430 BCE), Athens' strategy collapsed. Cleon advocated reckless expansion. Alcibiades proposed the Sicilian expedition. Nicias vacillated. The democracy, without a stabilizing figure, made catastrophic choices.

For Plutarch, this proves the point: individual character matters. Remove the right man, and everything falls apart.

Case Study: Alexander vs. Caesar

Plutarch pairs Alexander and Caesar to invite comparison. Both conquered vast territories. Both died violently. But their characters differed:

Alexander:

  • Driven by pothos (divine longing for the impossible)
  • Personally courageous (fought in the front line)
  • Generous to followers, cruel to resisters
  • Believed himself descended from gods

Caesar:

  • Driven by dignitas (status and honor within Roman norms)
  • Strategically brilliant but personally cautious
  • Politically calculating
  • Used divine descent as propaganda, did not believe it

Outcome: Alexander conquered the known world but left no stable successor state. His empire fragmented immediately upon his death. Caesar conquered Gaul methodically, used it to seize Rome, and established a political system (the Principate) that lasted centuries.

For Plutarch, the difference is character. Alexander's hubris and belief in his own divinity made him reckless. Caesar's calculated ambition made him effective.

The Moral Lesson

Plutarch's Lives are not neutral history. They are moral instruction through example. Good character leads to success and honor. Bad character leads to ruin.

Good men: Pericles, Cato, Fabius, Lycurgus — disciplined, wise, self-sacrificing.
Bad men: Alcibiades, Antony, Coriolanus — talented but self-destructive.

Plutarch believes we can learn from these examples. If we cultivate virtue, we can shape outcomes like Pericles. If we indulge vice, we will fail like Alcibiades.

II. Thucydides' Vision: Structure as Destiny

The Structural Cause of War

Thucydides opens with a sharp contrast to Plutarch's approach. He does not care about individual character. He cares about forces beyond individual control:

"The real cause I consider to be the one which was formally most kept out of sight. The growth of the power of Athens, and the alarm which this inspired in Lacedaemon, made war inevitable."

Notice the word: inevitable.

Thucydides argues that Athens and Sparta went to war not because Pericles, Archidamus, or any individual chose it, but because structural conditions — rising Athenian power, Spartan fear — made war the only possible outcome.

Individuals might delay or accelerate it. But they could not prevent it.

The Corinthian Speech: National Character as Structure

In Book I, the Corinthians deliver a speech contrasting Athenians and Spartans:

Athenians:

  • Addicted to innovation
  • Designs characterized by swiftness in conception and execution
  • Never at home, always abroad
  • Risk-takers who hope for more than they possess

Spartans:

  • Conservative, keep what they have
  • Slow to act, prefer the status quo
  • Home-bound, reluctant to venture abroad
  • Risk-averse, content with sufficiency

This is not individual psychology. It is collective character — the cultural traits of an entire people.

Thucydides uses this to explain strategic behavior:

  • Athens expanded aggressively because Athenian culture valued innovation and risk
  • Sparta resisted change because Spartan culture valued stability and tradition

The war was inevitable because these two incompatible systems could not coexist. One expanding power and one conservative power in proximity will eventually clash.

Pericles: Constrained by Structure

Plutarch presents Pericles as a great man who shaped Athens.
Thucydides presents Pericles as a skilled operator working within structural limits.

Pericles' strategy was brilliant:

  • Avoid land battles (Sparta's strength)
  • Use naval supremacy (Athens' strength)
  • Outlast Sparta financially

But the strategy depended on conditions Pericles could not control:

  • The plague (unpredictable, killed 1/3 of Athens including Pericles)
  • Democratic volatility (after Pericles died, Athens abandoned his strategy)
  • Spartan persistence (Sparta did not collapse financially as expected)

Thucydides' point: Even the best individual cannot overcome structural constraints. Pericles had a sound plan. Circumstances destroyed it.

The Melian Dialogue: Power as Determinant

The Melian Dialogue (Book V) is Thucydides' starkest statement of structural determinism.

Melos, a neutral island, refuses to submit to Athens. Athens demands submission. The Melians argue:

  • Justice protects the weak
  • The gods favor the righteous
  • Sparta will rescue us

Athens responds:

"The strong do what they can and the weak suffer what they must."

Melos refuses. Athens conquers it. The men are executed, women and children enslaved.

Thucydides is not endorsing this. He is analyzing it. In a world of power politics, capability determines outcomes, not justice, character, or divine favor.

Melos had no chance. Not because its leaders were unvirtuous or incompetent. Because structural power disparities made Athenian victory inevitable.

III. Herodotus: Fortune and the Limits of Human Control

Solon's Warning to Croesus

Herodotus Book I: Croesus, the richest king in the world, asks Solon: "Who is the happiest man you have ever seen?"

Croesus expects Solon to name him. Solon names:

  1. Tellus of Athens — prosperous city, good children, honorable death in battle
  2. Cleobis and Biton — strong sons who pulled their mother's cart to the temple, honored by the gods, died peacefully in their sleep

Croesus is offended. Solon explains:

"Call no man happy until he is dead. Fortune is fickle. Many rich men are miserable. Many poor men are blessed. Until life is finished, we cannot judge."

Years later, Croesus loses his kingdom, his son, and nearly his life. He remembers Solon's words and understands: human happiness depends on forces beyond individual control.

The Oracle's Deception

Croesus consulted the Delphic Oracle: "Should I attack Persia?"

The oracle responded: "If you cross the Halys River, you will destroy a great empire."

Croesus crossed. He destroyed his own empire. The oracle was truthful but deceptive.

Herodotus' lesson: Even kings who plan carefully, consult oracles, and act wisely cannot escape fate. Croesus did everything a prudent king should do. He still fell.

Cyrus' Death: The Pattern Repeats

Cyrus the Great, conqueror of Lydia and Babylon, is warned by Croesus (now his advisor) not to fight the Massagetai. Croesus tells him:

"Fortune is a wheel. The man on top will eventually fall."

Cyrus ignores the warning. He defeats the Massagetai through deception (using wine to intoxicate them). Queen Tomyris' son is captured and kills himself in shame. Tomyris, enraged, defeats Cyrus in battle. Persian forces are annihilated. Cyrus is killed.

Tomyris finds his corpse and plunges his head into a wineskin full of blood:

"You thirsted for blood. Now drink your fill."

The pattern: Even the greatest conqueror cannot escape fortune. Cyrus built the Persian Empire. He died ignominiously, defeated by a woman he had underestimated.

Herodotus' View: Fate Constrains, But Character Matters

Herodotus occupies a middle position between Plutarch and Thucydides:

  • Fate limits outcomes. Croesus and Cyrus were doomed regardless of their choices.
  • But character determines how you meet your fate. Croesus accepted his fall with dignity and became a wise advisor. Cyrus refused to listen and died violently.

Herodotus believes: You cannot control outcomes, but you can control how you respond to them. That is where character matters.

IV. Homer: Fate Fixed, Choice Real

Achilles' Choice

In the Iliad, Achilles knows his fate:

  • If he stays at Troy, he will die young but win eternal glory
  • If he returns home, he will live long but be forgotten

Fate is fixed. Achilles cannot escape death if he fights at Troy. But choice is real. He chooses glory over safety, honor over life.

This is the paradox: Fate determines the outcome, but humans choose which outcome to accept.

Hector's Final Stand

Hector knows he cannot defeat Achilles. The gods have withdrawn their favor. His brothers advise him to retreat behind Troy's walls.

Hector refuses:

"If I die, let me not die without a struggle, inglorious, but in some great deed of arms that men yet to be born will hear."

Fate is inevitable. Hector will die. But how he dies is a choice. He chooses to face Achilles with courage, knowing he will lose.

Thucydides would say: Hector's choice was irrational. He had no chance of winning. He should have retreated and preserved Trojan strength.

Homer says: The manner of death matters as much as the fact of death. Hector died gloriously. That is victory of a different kind.

The Gods and Fate

In Homer, the gods intervene constantly — Apollo sends plagues, Athena deflects spears, Aphrodite rescues Paris. But even gods cannot override fate.

Jupiter (Zeus) grieves for his son Sarpedon, who is fated to die. Juno (Hera) urges him to save Sarpedon. Jupiter refuses:

"Fate cannot be changed. If I save one mortal, every god will expect the same for their favorites. The order of the world will collapse."

Even the king of gods is constrained by fate.

The Homeric worldview:

  • Fate sets the ultimate outcome
  • Gods and humans can influence how and when, but not whether
  • Humans retain moral agency — they choose how to meet their fate

This is neither Plutarch's "character determines outcomes" nor Thucydides' "structure determines outcomes." It is: Outcomes are fixed, but choices still matter because they define who you are.

V. Tacitus: Character Under Constraint

The Emperor's Character Shapes Everything

Tacitus' Annals demonstrate a different dynamic: In an autocratic system, one man's character becomes a structural force.

Under the Republic, individual character mattered less because institutions constrained power. Under the Empire, the emperor's personality determines policy.

Augustus: Competent, restrained, cunning. Result → stable transition from Republic to Empire.
Tiberius: Brilliant but paranoid. Result → purges, terror, retreat to Capri.
Caligula: Mad. Result → chaos, assassination.
Claudius: Competent but manipulated. Result → stability undermined by palace intrigue.

Tacitus' insight: Institutions shape outcomes until institutions collapse. Then individuals do.

Rome's Republic constrained individual power through checks (Senate, tribunes, term limits). When those constraints disappeared, individual character became the primary variable.

Germanicus: The Lost Possibility

Tacitus presents Germanicus as the great "what if" of Roman history:

  • Noble, talented, beloved by soldiers and people
  • Competent general, fair administrator
  • Died young (possibly poisoned by Tiberius or Piso)

Tacitus implies: If Germanicus had lived, Rome might have been governed well. His death removed the possibility of virtuous autocracy, leaving only Tiberius' paranoid tyranny.

This is closer to Plutarch than Thucydides. Tacitus believes individual character could have changed outcomes — but only if circumstances allowed. Germanicus had potential, but structural forces (Tiberius' jealousy, palace conspiracies) destroyed him.

VI. Synthesis: When Does Character Matter?

The ancient sources converge on a nuanced answer: Character matters most when structural constraints are loose. Structure matters most when constraints are tight.

High Individual Agency (Character Matters More)

1. Periods of Transition
When institutions are weak or collapsing, individuals can shape outcomes more than usual.
Examples:

  • Caesar crossing the Rubicon (Republic → Empire transition)
  • Cyrus overthrowing Astyages (Media → Persia transition)
  • Vercingetorix uniting the Gauls (brief moment before Caesar's victory)

2. Small-Scale Decisions with Large Consequences
Sometimes a single choice cascades into massive outcomes.
Examples:

  • Pericles' decision to reject Sparta's peace offer (prolonged the war)
  • Alcibiades' defection to Sparta (changed Athenian strategy)
  • Nicias' delay in evacuating Sicily (destroyed the Athenian expedition)

3. Autocratic Systems
When one person holds absolute power, their character becomes a structural force.
Examples:

  • Tiberius' paranoia shaped Roman politics for 23 years
  • Alexander's ambition drove Macedon from regional power to world empire

Low Individual Agency (Structure Matters More)

1. Deep Structural Conflicts
When underlying forces are strong, individuals cannot prevent inevitable outcomes.
Examples:

  • Athenian-Spartan rivalry (cultural incompatibility made war inevitable)
  • Rome's Republic → Empire transition (civil wars made autocracy necessary)
  • Gallic fragmentation (tribal divisions ensured Caesar's victory even against Vercingetorix)

2. Material Constraints
When resources, geography, or logistics dominate, character becomes irrelevant.
Examples:

  • Athens in Sicily (logistics failure, disease, distance — no commander could save them)
  • Xenophon's Ten Thousand (hunger and cold mattered more than generals' skill)
  • Sparta vs. Athens (land power vs. sea power — structural mismatch)

3. Demographic and Economic Forces
Long-term trends constrain individual action.
Examples:

  • Rome's expansion (population growth, land hunger, military capacity created imperial momentum)
  • Athens' democratic volatility (institutional weakness invited demagoguery)

VII. The Modern Debate

This ancient tension reappears in modern historiography:

"Great Man" Theory (Plutarch's heirs):

  • Thomas Carlyle: "The history of the world is but the biography of great men."
  • Leaders like Churchill, Caesar, Napoleon shaped outcomes through will and character.

Structural/Materialist Theory (Thucydides' heirs):

  • Karl Marx: Economic forces determine outcomes; individuals are products of their time.
  • World War I was inevitable due to imperial competition, regardless of personalities.

Modern Consensus (Herodotus' heirs):

  • Both matter. The balance shifts depending on context.
  • Strong institutions constrain individuals. Weak institutions amplify them.
  • Contingency matters — small choices at critical junctures have outsized effects.

Conclusion: The Tragic View

The ancient world's deepest insight is neither Plutarch's heroism nor Thucydides' determinism. It is Homer's tragic view:

Fate constrains outcomes, but choices reveal character.

Hector cannot defeat Achilles. But he can choose to face him with courage.
Croesus cannot prevent his fall. But he can accept it with dignity.
Achilles cannot escape death. But he can choose glory.

This view acknowledges:

  1. Structural forces limit what is possible. Not all outcomes are achievable, no matter how virtuous the leader.
  2. Character determines which possible outcome occurs. Within constraints, individuals still choose.
  3. The manner of action matters as much as the result. How you fail defines who you are.

The most dangerous delusion is believing you have more control than you do (Croesus, Cyrus, Athens in Sicily). The second most dangerous is believing you have no control at all (fatalism, passivity, surrender to determinism).

The Wisdom is knowing which you face:

  • When structure dominates, adapt or perish (Xenophon in the Anabasis)
  • When agency is possible, act decisively (Caesar crossing the Rubicon)
  • When fate is inevitable, choose how you meet it (Hector's final stand)

History is neither made by great men nor by impersonal forces alone. It is made by individuals acting within constraints, sometimes transcending them, often succumbing to them, always revealing their character in how they respond.

That is the truth the ancient world understood, and which modern historiography is still struggling to articulate.
