On the Nature of the Gods

Cicero

Epicurean, Stoic, and Academic speakers confront accounts of gods, providence, and the world. Cicero distributes argument among several voices so theology, physics, and criticism of evidence can answer one another without a summary conclusion.

Before reading

What you will learn

Compare Epicurean and Stoic theologies, identify Academic criticism, and distinguish philosophical doctrine, civic rite, and authorial position.

Short summary

Epicurean, Stoic, and Academic speakers confront accounts of gods, providence, and the world. Cicero distributes argument among several voices so theology, physics, and criticism of evidence can answer one another without a summary conclusion.

Long summary

One exposition presents blessed gods detached from the world; another defends divine reason ordering the cosmos; Academic criticism tests their images, analogies, and consequences. Philosophical traditions thereby meet Roman cult.

The dialogue is not a Ciceronian catechism. Its plurality requires readers to distinguish the strength of a case, the objections answering it, and the public caution of an author committed to civic religion.
