Evangelicals and the plurality of worlds debate in Scotland, 1810–55

In the first half of the nineteenth century a remarkable group of Scottish evangelicals set out to address the theological questions raised by the possibility of intelligent life on other worlds. These included the popular science writer Thomas Dick, reformer and political economist Thomas Chalmers, natural philosopher David Brewster, and geologist and journalist Hugh Miller. All concluded that only a universe where life was ubiquitous would be compatible with the power and wisdom of the Deity. Each of them proceeded to formulate an answer to the problem of how the incarnation and atonement of Christ could relate to beings on other planets. The writings of these figures present a fascinating case study on how an important group of evangelical thinkers attempted to meet the challenges posed by modern science, not by rejecting its findings, but by developing a new synthesis between it and their religious beliefs.
