I've read Crime and Punishment but it still struck me as a simplified tale on crime with a rather laughable moral justification. (for its time it was probably very good though) I was looking for a little bit more analytical.
My interest in hard sci-fi sort of ended after Larry Niven (of which, I can heartily recommend the first Ringworld novel and most of his short stories. If you can track down the compilation Neutron Star you can't really go wrong. One of Niven's most interesting short stories is On the Theory and Practice of Teleportation where he establishes various parameters for a teleportation device, and looks at how that might impact society.)Someone please recommend me some diamond-hard sci-fi. I'm in the mood.
