Overview

The book is a series of letters to a young woman — Eugénie — that reason her, patiently and one prejudice at a time, out of her religion. Its title offers a préservatif contre les préjugés, a preservative against prejudice, and its claim is that piety serves a woman badly: devotion keeps her fearful, credulous and dependent where plain reason would leave her free. It was printed in Amsterdam in 1768 by Marc-Michel Rey, the Dutch bookseller who handled much of the century's forbidden trade, at Holbach's own expense and without any author's name on it. Jacques-André Naigeon supplied a preface partly meant to keep the authorship a mystery — a precaution that held for decades, since Holbach never claimed a single one of his attacks on religion. It never made the noise the System of Nature would, and it was not meant to: it aimed lower and closer, at the ordinary formation of a believer, and argued that unbelief was not a danger to a woman but a release. It reached English readers only much later, one more book that spent its first life in the underground channel that carried Holbach's nameless volumes across Europe.

Key concepts

Who is Eugenia in the book?

The young woman the letters are addressed to, a believer whose faith Holbach sets out to reason away. Whether she was real or a device, she gives the book its intimate frame: not a treatise aimed at everyone but counsel aimed at one person's formation. Writing to her lets Holbach argue close and personal, one prejudice at a time, rather than build a system.

Why does Holbach target a woman's faith in particular?

Because he thinks piety harms a woman more than most. Devotion, he argues, keeps her fearful, credulous and dependent, exactly the traits her society already imposed, where reason would leave her free and self-possessed. The book presents unbelief not as a danger to a woman's virtue but as a release from a servitude religion deepened. This gendered angle is what sets it apart from his general attacks.

What does the subtitle's 'preservative against prejudice' mean?

The book bills itself as a preservative, a preventive medicine, against prejudice. Prejudice here means belief held on authority and habit rather than reason, above all religious belief absorbed in childhood. Holbach's cure is patient argument that loosens each inherited certainty in turn. The medical image frames unbelief as health, and faith as an ailment reason can protect a mind from or nurse it out of.

How is this book different from Holbach's systematic works?

It is intimate where they are architectural. The System of Nature and Good Sense build or summarize a whole philosophy; the Letters simply work on one believer's mind, close and slow, without laying down materialist metaphysics. Holbach aimed it lower and nearer, at the ordinary making and unmaking of faith, and at readers, women especially, his louder books were not written for.

Why was it published anonymously in Amsterdam?

For the same reason as everything Holbach wrote against religion: safety. Marc-Michel Rey, the Dutch bookseller who handled the century's forbidden trade, printed it in 1768 at Holbach's own expense and without an author's name; Naigeon's preface helped keep the authorship a mystery for decades. Holbach never claimed a single one of his irreligious books, and this one spent its first life in that underground channel.

Themes of the book

What this book returns to, gathered into themes and ordered by how much of the text each one occupies.

What piety costs a woman

Does religion serve a woman well? Holbach's letters argue the reverse: devotion keeps her fearful, credulous and dependent, where plain reason would leave her free to think and act for herself.

The book is a series of letters coaxing a young woman, Eugenie, out of her faith one prejudice at a time, and its argument is pointed at her situation in particular. Piety, Holbach writes, serves a woman badly: it trains her to fear, to believe on authority, and to depend, when reason would make her free. He is not attacking a system so much as the ordinary formation of a believer, and he casts unbelief not as a danger to a woman but as a release. Printed in Amsterdam at his own expense and without his name, it aimed lower and closer than his systematic books, at a single life.

Reasoned out of faith, one prejudice at a time

Can a settled believer be argued free? The letters try, patiently dismantling the terrors and contradictions of dogma, on the wager that unbelief is not a loss but a relief.

Rather than storm religion with a system, Holbach works at close range, taking Eugenie's beliefs one at a time and reasoning her out of each: the fear of hell, the contradictions in the idea of God, the authority of priests. The method assumes that piety rests on prejudice sustained by habit, and that patient reason can loosen it. Its promise is that what waits on the far side of belief is not despair but calm and freedom. Quieter than the System of Nature and never as notorious, it aimed at the readers those louder books were not written for.

1766 Christianity Unveiled: Being an Examination of the Principles and Effects of the Christian Religion (Le Christianisme dévoilé)
The opening work in the run of anonymous antireligious books Holbach produced with his circle; the System of Nature and Good Sense that followed would build the philosophy out, where this one simply indicts the religion.

1770 Ecce Homo! Or, A Critical Inquiry into the History of Jesus of Nazareth: Being a Rational Analysis of the Gospels (Histoire critique de Jésus-Christ)
Where Christianity Unveiled indicts the religion and the System of Nature builds the philosophy, this one goes at the source texts, applying to the Gospels the historical scrutiny Holbach's circle applied to everything held sacred.
EN
1770 The System of Nature, or, the Laws of the Moral and Physical World (Système de la nature)
The centrepiece of Holbach's output and the fullest statement Enlightenment atheism produced: where the shorter books indict religion, this one lays down the whole materialist system — no God, no design, only matter in motion — that the rest assume.
EN
1772 Good Sense (Le Bon-Sens)
The popular abridgement of the System of Nature, written to carry the same atheism to readers who would never open the larger book; lighter, blunter, and the one of Holbach's works that reached furthest.
