I have to say, despite considering myself well read, I've only read a handful of those works, and there were several I hadn't even heard of.

I also wonder at the emphasis on modern physics and biology with the books on that list.

I do have to agree with Iris: given the conflict and progress it has spawned, the bible should be on such a list, along with the Koran. 'The Art of War' should also be included. Maybe Freuds masterpiece (the title of which escapes me at the moment). Argument could be made for Shakespheres plays as well (which I'll have to get to some day). 'Uncle Toms Cabin' would be another one.
