My favorite books are:
"On Human Nature" by E.O. Wilson Always believed this message and reading the book validated it.
"The Singularity is Near" by Ray Kurtzweil.....ruined reading science fiction for me...for the most part. Time to grow up. Now I see a different future for humanity.
"The Little Book of Atheist Spirtuality" by Andre' Comte-Sponville Smoothed the edges to my belief system.
