The Twenty Years' Crisis

The Twenty Years' Crisis: An Introduction to the Study of International Relations was written by E. H. Carr in 1939, with the second edition (ISBN: 0333069137) following it in 1946.

Chapter 1 is an exploration of epistemology of political science. The author's position is that a political science is necessarily a study of both what is and what ought to be. Persuading others about how to think about politics is itself a political act, and in turn influences politics. Still, the author differentiates "infantile", "utopian" theories that describe how things ought to be without regard for how things are, and scientific theories that describe how things are and infer how to make things more like they ought to be.

Author argues that there was no interest in international relations until WW1. At most there was an awareness of/anxiety towards war, and the best remedy to that was professional (not popular) diplomacy.

Author argues that the post WW1 regime was designed based on utopian theories that failed given a couple decades of crisis.

Altogether, these theories combined to suggest that free trade, democracy, and world peace are eventualities when the public is simply informed.

The author also explores the realist critique of this utopian theory, pulling from Machivelli, Bacon, Bodin, Hobbes, Spinoza...

The trap of realism, he describes, is determinism. A study of how things are too easily slips into a study justifying the way things are. A causative model that tries to map history, economic interests, or otherwise agents, onto policy outcomes has assumed that policy is deterministic on static parameters. At the same time, the supposition of an eventuality or equilibria that history races towards is a direct violation of the original framework.

These utopian ideas were baked into the post WW1 regime.

The contemporary failures of this regime were attributed to either "muddled thinking" (irrationality?) (Zimmern, Neutrality and Collective Security) or wickedness (following from the above equation to virtue) (Toynbee).

The idea that popular opinion was anti war is fundamentally flawed.

Ultimately, the concept of war being bad was quite eurocentric.

Politics is about power, and war is an intrinsic part of international relations.

The first factor of power is military strength.

Wars are fought to forestall fighting a war with worse odds later.

Economic strength is a factor of power, if only for the production of armaments. The policies to consider for increasing power are (1) autarky and (2) economic influence over other states.

The ability to persuade is a factor of power. Men must be convinced to go to war.

Public opinion is in fact dynamic, and any government's ability to coerce is limited, so really persuasion is everywhere.

Law is merely the reflection of politics. The only meaningful international laws are the ones that carry the interest of international powers.

Author predicts that if the League of Nations had sanctioned Italy for the invasion of Abyssinia and removed troops by force, the necessary next step would be occupation of all Italian foreign holdings, which certainly would lead to formal war.
