Is there intelligent life on other worlds? William Whewell, one of the most influential British intellectuals of the nineteenth century, weighed in on this question with Of the Plurality of Worlds. Writing anonymously, Whewell argued that there was no life anywhere else in the universe. Admitting such a possibility, he feared, would threaten humanity's special relationship with God, and open the door to supporters of evolution. The publication of Plurality in 1853 ignited a bitter Victorian debate on science and religion. This book reprints the first edition in facsimile, together with a vigorous response to his critics that Whewell added later and new introductory and bibliographic material by noted Darwin scholar Michael Ruse. This edition also includes 84 typeset pages--never before published--that Whewell cut from the original book at the last moment. Showing clearly the theological underpinnings of Whewell's thinking, these chapters also reveal the difficulties facing any Victorian who tried to reconcile traditional Christian thought with the findings of modern science.
