The brief

Peter Adamson and Melissa Lane argue that Herodotus and Thucydides are not just early historians but thinkers whose methods and set speeches place them at the origin of Greek political philosophy. Their works, Lane suggests, are best read alongside the Sophists and the Presocratics rather than against a modern idea of history.

The reasoning starts with the word historia itself, which means inquiry of any kind, not a fixed subject matter like the past. Both writers, Lane notes, were most confident describing events they or living witnesses had seen, which is why their treatment of the remote past differs from their treatment of contemporary war. This methodological concern connects them to the Presocratics' rational sifting of claims, though Lane complicates the picture for Herodotus, who also inherits from Homer a concern with preserving glory rather than only assessing truth. She traces a related difference in ambition: Herodotus is polymathic and inclusive of many stories, while Thucydides pursues strict accuracy, akribeia, and a single credible account. Both, however, use invented speeches, which Lane ties to sophistic rhetorical culture and to the plain fact that Greek and Persian political life ran on deliberation and speech.

The strongest point of contention concerns the Melian Dialogue. The usual reading takes it as Athenian cynicism trampling the weaker Melians' claim to justice. Lane complicates this by noting that Thucydides repeats the idea that justice holds only among equals elsewhere in the text, and by recalling that community organizers she read the dialogue with took the Athenian position seriously, arguing the Melians should have built strength rather than leaned on hope. This leaves open how condemnatory the scene really is.

The conversation closes by placing both historians behind Plato. Lane argues that Plato's Republic, staged after the trauma of the Peloponnesian War, and his account of political decline in Republic 8 and 9, function as philosophical counterhistories, Plato's own rival account of change against the narratives Herodotus and Thucydides had already given. Read this way, Plato's political philosophy looks less like a fresh start and more like an argument with the historians he had at hand.

Strongest arguments

Two related but distinct historical projects

3:49

Thucydides never names Herodotus but clearly reacts to him, criticizing details and inheriting his role as a large-scale prose predecessor. Herodotus is polymathic and inclusive, while Thucydides pursues akribeia, accuracy, through a single credible account. Lane suggests Thucydides fathers history proper while Herodotus also fathers geography and ethnography, so a single standard can mislead.

Historia means inquiry, not our modern history

5:34

The Greek word historia refers to method, inquiry of any kind, rather than a fixed subject matter like the distant past. Lane argues both historians wrote most confidently about contemporary events witnessed firsthand or attested by living witnesses, using autopsy and testimony rather than methods suited to the remote past.

Set speeches link the historians to sophists and real politics

11:08

Lane argues the invented speeches reflect sophistic rhetorical practice, including public recitation, but also reflect the real political fact that Greek and Persian polities conducted affairs through deliberation in councils and assemblies. Thucydides says he presents speeches as what speakers should or would have said, drawing on a sophistic notion of the fitting moment.

Herodotus's rationalism is qualified by Homer and glory

16:01

Herodotus resembles the Presocratics in rationally sifting competing stories, but he also inherits from Homer and Hesiod a concern with preserving glory, kleos, for great deeds. Lane notes he opens his work seeking to keep the deeds of Greeks and barbarians from being forgotten, using Homer's own word, which shows his method is not purely rationalist.

Freedom, slavery, and the diversity of customs

19:22

Lane argues Herodotus shows that attachment to freedom and fear of enslavement were shared across Persians, Greeks, and other peoples, not a uniquely Greek value, since losing a war often meant literal slavery. He also stresses the diversity of customs, nomoi, across peoples, connecting to the sophistic nomos-physis debate, though Lane resists calling him a strict relativist and notes some scholars see his ethnography as rhetorically shaped.

The Melian Dialogue as a study of justice, power, and self-delusion

28:13

Lane presents the Melian Dialogue as a highly constructed set piece, often read as justice versus self-interest between the weaker Melians and stronger Athenians. She complicates this by noting the claim that justice applies only among equals recurs elsewhere in Thucydides, by recalling community organizers reading the Athenian position sympathetically, and by stressing that the Melians rely on hope rather than justice, a reliance that proves self-delusional.

Thucydides's ambivalence toward democracy and Pericles

33:29

Lane argues Thucydides's sympathies were not entirely with democracy, pointing to his praise of the mixed Constitution of the 5,000 as the best regime he witnessed and his remark that Pericles led the people rather than being led by them. She stresses that what Thucydides and later Socrates criticize is specifically imperial Athenian democracy, not democracy as such.

Plato reworking the historians into philosophical counterhistories

39:16

Lane argues Herodotus and Thucydides were the main prose models available to Plato, and that his critique of imperial Athens, the Republic's staging after the Peloponnesian War, and his accounts of political decline in Republic 8 and 9 and Laws Book 3 amount to Plato rivaling the historians with his own account of political change.

Disagreements

Does the Melian Dialogue condemn or vindicate Athens

30:37

Lane contrasts the common reading that the dialogue shows Athenians cynically trampling justice with an alternative she encountered reading it alongside community organizers, who took the Athenian claim that justice only holds among equals seriously and concluded the Melians should have built strength rather than relied on hope.

Was Herodotus a relativist about customs

21:06

Lane addresses whether Herodotus's emphasis on the diversity of nomoi makes him a relativist in the sophistic nomos-physis sense, and gives her own view that he is not exactly a relativist even though he highlights diversity and does not always assess competing customs.

Questions this episode answers

  • What is the relationship between Herodotus and Thucydides?

    3:49

    Thucydides never names Herodotus but criticizes specific details and reacts to his method, since Herodotus was the only major prose predecessor at that scale, and Thucydides pursues strict accuracy over Herodotus's more inclusive, polymathic approach.

  • What does the Greek word historia actually mean?

    5:34

    Historia means inquiry of any kind, referring to method rather than subject matter, and both historians wrote most confidently about contemporary events they had witnessed or heard from living witnesses rather than the distant past.

  • Why do Herodotus and Thucydides include invented speeches in their histories?

    11:08

    The set speeches reflect both the sophistic culture of rhetoric and public recitation, and the real fact that Greek and Persian political life was conducted through deliberative speech in councils and assemblies, making speeches central to the action itself.

  • Is Herodotus a cultural relativist about customs and laws?

    21:06

    Lane argues Herodotus is not exactly a relativist despite his emphasis on the diversity of nomoi across peoples, though this diversity connects to the sophistic nomos-physis debate about whether law is rooted in nature or merely customary.

  • What is the message of the Melian Dialogue in Thucydides?

    28:13

    The dialogue stages a debate over whether justice applies only among roughly equal powers, with the Athenians appealing to advantage and the Melians to hope rather than justice. Lane notes the claim about justice among equals recurs elsewhere in Thucydides, complicating a simple reading of Athenian cynicism.

Related primary passages

He who acts unjustly acts impiously. For since the universal nature has made rational animals for the sake of one another to help one another according to their deserts, but in no way to injure one another, he who transgresses her will, is clearly guilty of impiety towards the highest divinity.

The opening claim of the whole meditation: injustice is not a social lapse but a break with the rational order that made us for each other.
