The Levels of Analysis
Thucydides' History is not just a chronicle of battles. It is a study of political behavior.
To help navigate his work, we can use the framework that Kenneth Waltz established in Man, The State, and War, which divides conflict into three "images" or levels.
Thucydides refuses to simplify.
He reveals a tragic, mutually reinforcing cycle: while human fear drives the state to war, the anarchy of the war recoils back—radicalizing the state's politics and dehumanizing the individual's nature.
Level I: The Individual (Physis)
Fear, Honor, and Interest: Thucydides argues that all human action—and by extension, state actions—stems from these primal drivers, often masking themselves as "justice."
Hope vs. Reality: The dangerous gap between Logos (words and plans) and Ergon (deeds and reality); how "hope" blinds leaders to the cold math of probability.
The Corrosion of Morality: How moral laws (justice) disintegrate under the pressures of Ananke (expedience or necessity); the struggle to maintain civilization when survival is at stake.
Level II: The State (Polis)
Democracy vs. Oligarchy: The contrast between the energetic, fickle nature of Athenian democracy and the slow, cautious stability of Spartan oligarchy.Sea Power vs. Land Power: How geography shapes ideology—the commercial, imperial logic of the navy (Athens) versus the agrarian, isolationist logic of the Army (Sparta).
Civil Strife (Stasis): The internal collapse of the state; how polarization and faction destroy a city more effectively than an invading army.
Level III: The System (Kinesis)
Escalation Dynamics: The "truest cause" of the war—the inevitable conflict caused by the growth of Athenian power and the fear it inspired in Sparta.
Empire and Hegemony: The paradox of hegemony; why empires constantly expand to appear strong, even when expansion leads to strategic overreach.
Alliance Politics: How great powers lose control of their destiny by getting dragged into wars tied to the grievances of smaller allies.

Level I: The Individual (Physis)
The unchangeable constants of human nature that drive all political behavior
Level II: The State (Polis)
How domestic structure and material resources shape state behavior
Level III: The System (Kinesis)
The dynamics of power and conflict in an anarchic international system
Systemic Dynamics: The Reinforcing Loop
It is not a linear path from Man to War, to use Waltz's parlance. The pressure moves both ways.
As you work through the book, bear this dynamic in mind. You can explore how the levels interact in two critical events:
- The Plague of Athens | Upward Pressure (Micro → Macro)
How the psychological collapse of the Individual (fear of death) destroyed the political order of the State, causing the failure of the Systemic grand strategy. - The Corcyraean Civil War | Downward Pressure (Macro → Micro)
"War is a violent teacher." How the pressure of the international System radicalized the domestic State, eventually mutating the Individual psyche until "words changed their meanings."
Thucydides operates at all three levels simultaneously, making his work uniquely sophisticated as political theory and as a framework for thinking about world events.
