The Necessity of Atheism — A Reader’s Guide

Rhetorical Framing and Diction

Brooks’s language is deliberately confrontational. He describes religious beliefs as “crutches” and “encumbrances,” and he characterizes orthodox believers as assuming the freethinker acts “with regret.” The preface’s epigraph from Nietzsche—where gods “laughed themselves to death”—signals a scornful, almost gleeful tone. Throughout the excerpts, Brooks uses terms like “delusion,” “atrocities,” and “mercilessness” to describe religious history. His choice of the word “magician” for Jesus in the witchcraft chapter is a calculated provocation, reducing miracles to tricks. This diction is not neutral; it is designed to undermine reverence and frame religion as a harmful superstition.

Use of Biblical and Historical Evidence

Brooks grounds his argument in specific biblical passages, quoting Exodus 22:18 (“Thou shalt not suffer a witch to live”) and Matthew 8:28–32 (the Gadarene swine). He then argues that these texts provided “the chief source and sanction” for the witch hunts. His method is to take scripture literally and then hold it responsible for historical atrocities. He cites a French judge, Boguet, who “burnt multitudes of lycanthropes” and wrote a code permitting witches to be strangled but lycanthropes to be “burnt alive.” Brooks does not merely assert a link; he traces a causal chain from biblical commands to church-sanctioned violence, using specific names and dates to lend his argument an empirical weight.

Structure and Cumulative Argument

The book’s table of contents reveals a systematic progression: after chapters on the evolution of beliefs and the prophets, Brooks devotes separate chapters to religion’s conflicts with science, medicine, astronomy, geography, chemistry, physics, geology, philology, and evolution. This encyclopedic approach aims to show that religion has been refuted in every field of knowledge. The later chapters on morality, war, slavery, labor, and women extend the critique to social ethics. The final chapter, “Contemporary Opinion,” suggests Brooks sought to anchor his argument in the views of his time. The structure itself is a rhetorical device: by accumulating evidence across domains, he attempts to make the case for atheism seem inevitable.

Voice and Authorial Stance

Brooks writes as a polemicist, not a dispassionate scholar. He uses the first-person plural (“we”) to align himself with the reader against the “orthodox believer.” His sentences are often declarative and sweeping: “There are no problems related to human progress and happiness in this age which any theology can solve.” He frequently invokes authorities—Havelock Ellis, Draper, Nietzsche—to bolster his position. Yet his voice is also that of a compiler: long lists of biblical references (devil, Satan, witch, etc.) and historical examples (Boguet, the Council of Ancyra) suggest a methodical, almost legalistic accumulation of evidence. The combination of passionate rhetoric and catalogued facts gives the text a distinctive, urgent tone.

Readers should note that Brooks’s argument is built on a literalist reading of scripture and a selective use of history. His evidence is marshaled to support a predetermined conclusion, and the book’s structure is designed to overwhelm rather than persuade through nuance. Approaching it as a primary document of early 20th-century freethought—rather than as a balanced inquiry—will help the reader appreciate its rhetorical strategies and historical context.

There’s a certain loneliness in a book that argues so fiercely for disbelief—I remember feeling it while reading The Necessity of Atheism, its bracing certainty. Yet afterward, I found myself reaching for something quieter, almost companionable, in The Cradle of the Christ: A Study in Primitive Christianity — Reading Notes. Both wrestle with belief, but one leaves the room; the other, somehow, keeps the door open.
