I: The Relation of Defence to Aggression explained

This chapter argues that the necessity for armaments arises from the motive for aggression, and that reducing that motive is a more effective form of defence than military buildup.

What happens

This chapter argues that the necessity for armaments arises from the motive for aggression, and that reducing that motive is a more effective form of defence than military buildup. Angell responds to critics who misunderstand his position, clarifying that he does not advocate abandoning self-defence but rather addressing the economic illusions that drive aggression. He uses the analogy of a bank replacing gold with checks to illustrate how economic changes can eliminate the incentive for attack, and he emphasizes that nations are justified in defending even their follies against attack.

Themes in this chapter

  • Economic Futility of War

    Angell argues that military force is economically futile, as conquest cannot seize modern intangible wealth.

  • Interdependence of Nations

    The chapter highlights how financial interdependence makes aggression counterproductive for the aggressor.

  • Illusion of Political Power

    Angell challenges the universal belief in the social and economic advantages of successful conquest.

  • Critique of Militarism

    The chapter critiques the assumption that armaments are purely defensive, showing they stem from aggressive motives.

Characters to notice

Key passages

  • Necessity for defence arises from the existence of a motive for attack

    The need for defence is created by the presence of a reason for someone to attack.

    Angell's central platitude that underlies the relation of defence to aggression.

  • the mechanical development of the last thirty or forty years, especially in the means of communication, had given rise to certain economic phenomena—of which reacting bourses and the financial interdependence of the great economic centres of the world are perhaps the most characteristic—which render modern wealth and trade intangible in the sense that they cannot be seized or interfered with to the advantage of a military aggressor

    Recent technological advances have made wealth and trade intangible, so they cannot be captured by military force.

    Angell's key argument that economic interdependence makes conquest futile.

  • the bank was never attacked again. Now, the demonstration that gold had been replaced by books in that bank was as much a work of defence as though the bank had spent tens of thousands of dollars in constructing forts and earthworks

    Eliminating the motive for attack is a more effective and cheaper form of defence than military fortifications.

    Analogy illustrating that removing the incentive for aggression is a superior defence strategy.
