The Optimal Size of States: A Philosophical Inquiry

Overview

In this study, we explore the concept of state size in relation to national defense and survival. Aristotelian thinking on this matter is contrasted with modern liberal perspectives, highlighting the tension between liberalism and the need for a robust military presence. We examine how the size of states affects their ability to defend themselves against external threats.

Context

The concept of state size has been debated throughout history. In ancient Greece, the city-state was a common form of governance, but it proved vulnerable to larger powers such as Macedonia. This led to the rise of larger entities like the Hellenistic kingdoms and eventually the Roman Empire. In modern times, the nation-state has become the dominant form of governance.

Timeline

Ancient Greece: City-states like Athens and Sparta coexist with smaller and larger polities.
Aristotle’s Politics (c. 350 BCE): The philosopher argues that a state must be large enough to defend itself, but small enough to maintain civic virtue.
Hellenistic Period (323-31 BCE): Kingdoms like Macedon and Ptolemaic Egypt emerge as dominant powers in the Mediterranean.
Roman Empire (27 BCE-476 CE): The empire expands across Europe, North Africa, and parts of Asia.
Renaissance Humanism (14th-17th centuries): Thinkers like Machiavelli and Hobbes begin to question traditional notions of state size and power.
Modern Liberalism (18th-19th centuries): Philosophers like Locke, Rousseau, and Kant emphasize individual rights and the social contract.
World Wars I and II (1914-1945): The devastating consequences of aggressive militarism lead to calls for international cooperation and collective security.
Cold War (1945-1991): Superpowers like the United States and Soviet Union engage in a decades-long struggle for global influence.

In a world where military might is still an essential factor in global politics, states must balance their commitment to peace and international cooperation with the need for robust national defense.
