The author makes dismantling the Pentateuch look easy. I have yet to hear or read a theologian debater or writer who is the equal of Ingersoll, or able to present any persuasive rebuttal in response to his arguments. Rather, generally, Ingersoll's detractors have either: urged the faithful to ignore his arguments; and/or heaped personal attacks upon him. Ironically, this is the same methodology that hate groups such as the KKK, the Neo-Nazi's, and others of their ilk, use in response to those who urge different views. The rationale of such strategy is that the end justifies the means. However, such conduct tacitly ackowledges that the defenders of the faith have conceded they cannot directly confront Ingersoll's arguments and ideas on the merits.
Ingersoll's chapters on Noah's Ark and the flood to end all floods (pages138-168), the plagues God had Moses inflict upon Egypt (pages 190-209), the tower of Babel (pages 169-175), and the Jews flight from Pharaoh, including their forty years of wandering in the Sinai Desert (pages 210-240), render these stories fanciful and unworthy of literal belief, much less divine inspiration. This book is a must read for any thinking Christian or Jew. The author demonstrates logic, common sense,and humor. Ingersoll disects the contradictions and impossibilities of these, and other, Old Testament scriptures.
I am now reading "American Infidel: Robert G. Ingersoll", a biography by Orvin Larson. I recommend it as a good read too.
