This relatively short booklet is on the dual topic of Satan and Hell. In refutation of the religiosity which marked the 19th century, Ingersoll argues against a Devil's existence on a twofold platform; first logical and second emotional. The first, which occupies the bulk of the work, ruminates primarily on inconsistencies within the Bible.As one of the major orators and philosophical minds of his day, Ingersoll here lays out his case for the superiority of there being no spiritual world at all, as opposed to the one professed by the specifically orthodox and very religious.
