The New Atlantis has just posted a very interesting article from their latest issue about Charles Darwin's personal sensitivity to the problem of evil and suffering in nature, and how it influenced his views on evolution. It is entitled "Darwin's World of Pain and Wonder." Excellent. I recommend it highly.
It calls to mind an excellent book I read on the same subject not long ago, entitled "Darwin's God" by Cornelius Hunter, about which I wrote some thoughts at the time.
Another very interesting article on evil I found via Wikipedia. It is by a Catholic theologian, explaining the theodicies, or defenses of God against evil and suffering, offered by Saints Augustine and Ireneaus. I found it interesting because it acknowledges how many puzzling issues remain for the believer even today. Of course, the author attempts to resolve some of those problems in his theory of "salvation." Which I will continue reading with interest.
