Baruch Spinoza

1632–1677 · Rationalism · Early modern

Baruch Spinoza was born in Amsterdam in 1632, in the Portuguese Jewish community, and was expelled from the synagogue in 1656. He made a living grinding lenses and died in 1677. The Ethics, published just after his death, is written in Latin like geometry: definitions, axioms, propositions, and scholia. There is one substance, God or nature.

Whatever is, is in God. The order of ideas is the order of things. Human actions are to be studied as lines and planes are studied. Each thing strives to persevere. People think themselves free because they feel their appetites and miss the causes. Virtue is power to seek one's own advantage, rightly understood, and blessedness is that virtue, not a later reward.

Something of the mind is eternal, and the claim is not a personal afterlife. Edwin Curley's translation is the English this library follows. A two-word equation, God or nature, is the most dangerous quotation in the book, because it is exact and almost never self-explanatory.

Ethics, part 1 appendix, then part 3 preface and propositions 6 to 9, in Curley

The appendix is continuous prose on the prejudice of freedom. The opening of part 3 shows the method and the striving on which the ethics runs.

Key ideas

  • One substance

    Whatever is, is in God, and God is nature, not a person outside the world issuing decrees.

  • Striving

    Each thing strives to persevere, and human virtue is power to seek one's own advantage under that striving.

  • Freedom as understanding

    People feel free because causes are hidden, and real freedom is acting from adequate ideas, not being uncaused.

  • Blessedness

    Blessedness is virtue itself, the intellectual love of God, not a wage paid after the act.

Major works

  • Ethics (completed by 1675, published 1677)
