Great list! You might have excluded non-fiction, but ok. And since “everyone has an opinion”...
- Faust by Goethe
- Rules for Radicals by Alinsky (sigh)
- Principia by Newton
- Two Treatises of Civil Government by Locke
- Atlas Shrugged by Rand
- Meditations on First Philosophy by Descartes
- 100 Years of Solitude by Marquez [Latin American representation]
- Fear and Trembling by Kierkegaard
- Civization and its Discontents by Freud (sigh)
I would rate Borges as a much better South American writer than Marquez, and also Cortázar.
