The Industrial Revolution was well under way and people were looking for some way to justify the cruelty that accompanied this revolution. (Child labor, sweat houses, etc. ) Darwin's book was just what the world needed to justify the cruel ruthless tactics of the industrial revolution. Darwin had a theology degree. He became a deist, and later, very proudly an atheist. There are many stories of him repenting on his death bed, but there still is much confusion on the issue.
