This little quiz that I found on R's blog matches rather synchronously with the book I'm reading entitled Peace on Earth by Stanislaw Lem.

The premise of the story is that a man has been sent to the Moon to spy on the robotic war machines there. He is shot by a ray which cleanly bissects his corpus callosum, the large nerve bundle that connects the right and left hemispheres. This causes his right hemisphere (the creative, intuitive side) to become independent of his left hemisphere (the anal-retentive, type A side) and the right side seems to be unable to stand the left. As they say, hilarity ensues.

Stanislaw Lem is a Polish science fiction writer. The books of his that I've read are really philosophical and, at times, satiric, informed by Cold War sensibilities and perspectives on both the capitalist and communist side of things. He also seems to have predicted a lot of what would happen once the Cold War was over. Some of his other books that I've read include Solaris which was made and re-made into a movie and Chain of Chance

But it turns out that I'm actually pretty right-brained, which explains a lot.
