The Great Monkey Trial

In the preface, de Camp states that the books goal is to "tell the story of the Scopes evolution trial of 1925, at Dayton, Tennessee, as truthfully as possible."[6] De Camp rejects previous descriptions of the trial such as "a witch hunt", "a travesty of justice", or "a deathblow to Fundamentalism." Instead, de Camp classifies the trial as one battle in a long and ongoing war between two philosophical worldviews. The first, a "theistic view", sees the world as governed by entities that are sensitive to human sentiment and are not bound by natural law in their actions. The second, a "mechanistic view", sees the world as governed by absolute and unchanging natural laws, which gods cannot affect.[7]

In summation of the trial's cultural impact, de Camp suggests that the public ridicule placed on the law by this trial may have influenced politicians against supporting other such "monkey laws". He also suggests that the trial accomplished its goal of raising public interest in evolution. In conclusion, de Camp states that the truth is always competing against many other factors in shaping public perception, but truth has the advantage of persistence.[8]

The book frames the trial as a militaristic conflict, frequently using terms such as skirmish and combatant. Additionally, it includes chapter titles such as "The War Cries and Banners", "The Crusade" and "The Din of Battle Rises".[9] Each chapter has a quote at the start which holds some relevance to its contents. These include historical examples of conflict between religion and science, such as selections from Darwin's Origin of Species and the Inquisition's Condemnation of Galileo, as well as more poetic statements on human nature from Shakespeare and Lewis Carroll.

Reviews praised the book for its comprehensiveness.[10] Several reviewers have commended the book for providing a factual and unbiased portrayal of the full story of the trial, as opposed to the fictionalized Inherit the Wind or the one-sided H.L. Mencken reporting that they claim shaped previous public perception of the Scopes trial.[11][12] Some have held that this and other "books written specifically about the Scopes trial serve ... to reinforce the spirit of ridicule" associated with the trial.[13]

Kirtley Mathers, one of the scientists who testified for the defense in the Scopes Trial, spoke highly of the book in a review that appeared in Science. Mathers referred to the book as the definitive account of the Scopes trial, praising its ability to capture both the atmosphere and the human element of the trial. Mathers also highly commended the research that went into the book. However, he notes one instance where he feels that de Camp misrepresents thoughts that may have gone through trial members' minds as things which were actually said in court. Mathers also notes several typographic errors, including a few relating to the dates of his own interviews.[14]

The Scopes Trial was also the subject of a chapter in Darwin and His Great Discovery, written by the author in collaboration with his wife Catherine Crook de Camp and published in 1972.
