Stainislaw Lem

I bumped into an article on Slashdot a couple of days ago about "The Futurological Congress" written by Stainislaw Lem - - I'd never heard about him but it did raise my curiosity enough to go to the site of all semi-relevant human knowledge (wikipeidia) and search his name.

Some of the quotes they had from his work seemed to hit a note:

This one sounds like a politician's motto: "The ancients used to say: mundus vult decipi, ergo decipiatur — the world wants to be deceived, so let it be deceived."

"he who can transform himself has no one in the world but himself to blame for his failings, no one but himself to hold responsible for his dissatisfaction."

Seems like an interesting writer and possibly a worthy read, but he wrote a lot so I'm curious. Where's the best place to start?
