Critique of Judgment
1790 · 448 pages
Beauty sits in no object, yet you expect everyone to agree with you. Kant grounds that strange demand, and shows why a raging ocean enlarges the person watching it rather than crushing him.

Meditations on First Philosophy
1641 · 59 pages
Descartes sits by a fire and doubts everything, down to whether a demon feeds him the world. What survives is the thinking, and philosophy has argued from there ever since.

Ethics
1667 · 208 pages
Spinoza proves, in numbered propositions, that God and nature are one substance and that everything follows from it as necessarily as a theorem. Freedom is understanding that necessity, not escaping it.

Critique of Practical Reason
1788 · 224 pages
You know you ought to do what you would rather not, and Kant takes that as proof you are free. Freedom, God, and immortality return as what practical reason must assume.

Groundwork of the Metaphysics of Morals
1785 · 130 pages
Nothing is good except a good will. From that Kant derives two commands: act only on a principle you could will everyone to follow, and treat persons as ends, never merely as means.

1637 · 207 pages

Early Greek Philosophy
Various and Jonathan Barnes
500 BC · 282 pages

Foundation
1951 · 320 pages
Hari Seldon predicts the Galactic Empire's fall and thirty thousand years of darkness, then founds a colony to cut the wait to one thousand. Paul Krugman went into economics wanting Seldon's job.

Discourse on Metaphysics
1686 · 84 pages
