Well, if you guys are going to get Classic on me, I'll add the following:
All the writings of Plato are a must.
Most of the plays by Shakespeare.
Homer's Oddessy.
Hobbe's Leviathan.
More modern, but intellectually interesting and full of insight:
A Brief History of Time, S. Hawking
Dungeon, Fire & Sword, J. Robinson
Hyperspace, M. Kaku
Holy Blood, Holy Grail, Baigent/Liegh/Lincoln
The Raven, Marquis James
A History of God, K. Armstrong
The Demon Haunted World, C. Sagan.
The Bell Curve, Herrnstien/Murray
The End of History and The Last Man, Fukuyama
Man, The State and War, Waltz
On the more practical side of everyday insight are:
Life is a Contact Sport, Ken Kragen
The Way you wear your hat, Bill Zehme
Hope is Not a Method, Gen. G. R. Sullivan
On the fun side, I can't believe I forgot David Morrell.. he rocks...My favorites include:
The Fifth Profession
Bortherhood of the Rose
The League of Night and Fog
First Blood
The Fraternity of the Stone
