Hmmm... pretty tall order.
Moby-Dick. Greatest novel in existence.
Huckleberry Finn. Second greatest novel in existence.
The Border Trilogy, Cormac McCarthy
Love in the Time of Cholera, Gabriel Garcia Marquez
Origin of the Species, Charles Darwin
Shakespeare. All of it.
Nothing by Henry James (that's not the title of a novel).
Agents of Innocence, David Ignatius (a light read)
A Farewell to Arms, Hemingway
The Gate, Bizot (remarkable autobiographical account of a Frenchman in Cambodia as the Khmer took power)
Nothing by any existentialist, with the exception of The Brothers Karamazov (the third greatest novel in existence).
Essence of Decision, Graham Allison (analysis of Cuban Missile Crisis, but a great general and fascinating introduction to political analysis)
Principles of Neural Science, Kandel et al
On Liberty, JS Mill
Theory of Justice, John Rawls
Anything by Gordon Wood or Bernard Baylin.
In Retrospect, Robert McNamara
The Sweet Science, A.J. Liebling
Strategy, B.H. Liddell Hart
Blindness, Saramago
At least one introductory textbook each on macroeconomics and microeconomics
I should stop... I guess perhaps some of Richard Rorty's papers, though I forget the titles at the moment.
