The Ethics

In 'The Ethics,' Spinoza presents a comprehensive philosophical system that covers metaphysics, epistemology, and ethics.

The book is divided into five parts and argues that the universe is governed by rational laws, and that reason is the primary guide for living.

Spinoza rejects transcendent good and evil, Cartesian dualism, and the anthropomorphization of God, instead positing an ethical system based on joy and the pursuit of understanding and virtue.
