A une extréme justesse d'esprit il joignait une simplicité de moeurs tout-à-fait antique et patriarcale.

J. A. Naigeon, _Journal de Paris_, le 9 fev. 1789

Diderot, writing to the Princess Dashkoff in 1771, thus analysed the spirit of his century:

Chaque siècle a son esprit qui le caractérise. L'esprit du nôtre semble être celui de la liberté. La première attaque contre la superstition a été violente, sans mesure. Une fois que les hommes ont osé d'une manière quelconque donner l'assaut à la barrière de la religion, cette barrière la plus formidable qui existe comme la plus respectée, il est impossible de s'arrêter. Dès qu'ils ont tourné des regards menaçants contre la majesté du ciel, ils ne manqueront pas le moment d'après de les diriger contre la souveraineté de la terre. Le câble qui tient et comprime l'humanité est formé de deux cordes, l'une ne peut céder sans que l'autre vienne à rompre. [Endnote 1:1]

The following study proposes to deal with this attack on religion that preceded and helped to prepare the French Revolution. Similar phenomena are by no means rare in the annals of history; eighteenth-century atheism, however, is of especial interest, standing as it does at the end of a long period of theological and ecclesiastical disintegration and prophesying a reconstruction of society on a purely rational and naturalistic basis. The anti-theistic movement has been so obscured by the less thoroughgoing tendency of deism and by subsequent romanticism that the real issue in the eighteenth century has been largely lost from view. Hence it has seemed fit to center this study about the man who stated the situation with the most unmistakable and uncompromising clearness, and who still occupies a unique though obscure position in the history of thought.

Holbach has been very much neglected by writers on the eighteenth century. He has no biographer. M. Walferdin wrote (in an edition of Diderot's Works, Paris, 1821, Vol. XII p. 115): "Nous nous occupons depuis longtemps à rassembler les matériaux qui doivent servir à venger la mémoire du philosophe de la patrie de Leibnitz, et dans l'ouvrage que nous nous proposons de publier sous le titre "D'Holbach jugé par ses contemporains" nous espérons faire justement apprécier ce savant si estimable par la profondeur et la variété de ses connaissances, si précieux à sa famille et à ses amis par la pureté et la simplicité de ses moeurs, en qui la vertu était devenue une habitude et la bienfaisance un besoin." This work has never appeared and M. Tourneux thinks that nothing of it was found among M. Walferdin's papers. [2:2] In 1834 Mr. James Watson published in an English translation of the _Système de la Nature_, _A Short Sketch of the Life and the Writings of Baron d'Holbach_ by Mr. Julian Hibbert, compiled especially for that edition from Saint Saurin's article in Michaud's _Biographie Universelle_ (Paris, 1817, Vol. XX, pp. 460-467), from Barbier's _Dict. des ouvrages anonymes_ (Paris, 1822) and from the preface to the Paris edition of the _Système de la Nature_ (4 vols., 18mo, 1821). This sketch was later published separately (London, 1834, 12mo, pp. 14) but on account of the author's sudden death it was left unfinished and is of no value from the point of view of scholarship. Another attempt to publish something on Holbach was made by Dr. Anthony C. Middleton of Boston in 1857. In the preface to his translation to the _Lettres à Eugenia_ he speaks of a "Biographical Memoir of Baron d'Holbach which I am now preparing for the press." If ever published at all this _Memoir_ probably came to light in the _Boston Investigator_, a free-thinking magazine published by Josiah P. Mendum, 45 Cornhill, Boston, but it is not to be found. Mention should also be made of the fact that M. Assézat intended to include in a proposed study of Diderot and the philosophical movement, a chapter to be devoted to Holbach and his society; but this work has never appeared. [3:3]

Of the two works bearing Holbach's name as a title, one is a piece of libellous fiction by Mme. de Genlis, _Les Diners du baron d'Holbach_ (Paris, 1822, 8vo), the other a romance pure and simple by F. T. Claudon (Paris, 1835, 2 vols., 8vo) called _Le Baron d'Holbach_, the events of which take place largely at his house and in which he plays the rôle of a minor character. A good account of Holbach, though short and incidental, is to be found in M. Avézac-Lavigne's _Diderot et la Société du Baron d'Holbach_ (Paris, 1875, 8vo), and M. Armand Gasté has a little book entitled _Diderot et le cure de Montchauvet, une Mystification littéraire chez le Baron d'Holbach_ (Paris, 1895, 16vo). There are several works which devote a chapter or section to Holbach. [3:4] The French critics and the histories of philosophy contain slight notices; Rosenkranz's "Diderot's Leben" devotes a chapter to Granval, Holbach's country seat, and life there as described by Diderot in his letters to Mlle. Volland; and he is included in such histories of ideas as Soury, J., "Bréviaire de l'histoire de Matérialisme" (Paris, 1881) and Delvaille, J., _Essai sur l'histoire de l'idée de progrès_ (Paris, 1910); but nowhere else is there anything more than the merest encyclopedic account, often defective and incorrect.

The sources are in a sense full and reliable for certain phases of his life and literary activity. His own publications, numbering about fifty, form the most important body of source material for the history and development of his ideas. Next in importance are contemporary memoirs and letters including those of Voltaire, Rousseau, Diderot, Grimm, Morellet, Marmontel, Mme. d'Epinay, Naigeon, Garat, Galiani, Hume, Garrick, Wilkes, Romilly and others; and scattered letters by Holbach himself, largely to his English friends. In addition there is a large body of contemporary hostile criticism of his books, by Voltaire, Frederick II, Castillon, Holland, La Harpe, Delisle de Sales and a host of outraged ecclesiastics, so that one is well informed in regard to the scandal that his books caused at the time. Out of these materials and other scattered documents and notices it is possible to reconstruct--though somewhat defectively--the figure of a man who played an important rôle in his own day; but whose name has long since lost its significance--even in the ears of scholars. It is at the suggestion of Professor James Harvey Robinson that this reconstruction has been made. If it shall prove of any interest or value he must be credited with the initiation of the idea as well as constant aid in its realization. For rendering possible the necessary investigations, recognition is due to the administration and officers of the Bibliothèque Nationale, the British Museum, the Library of Congress, the Libraries of Columbia and Harvard Universities, Union and Andover Theological Seminaries, and the Public Libraries of Boston and New York.

CHAPTER I. HOLBACH, THE MAN.

Paul Heinrich Dietrich, or as he is better known, Paul-Henri Thiry, baron d'Holbach, was born in January, 1723, in the little village of Heidelsheim (N.W. of Carlsruhe) in the Palatinate. Of his parentage and youth nothing is known except that his father, a rich parvenu, according to Rousseau, [5:5] brought him to Paris at the age of twelve, where he received the greater part of his education. His father died when Holbach was still a young man. It may be doubted if young Holbach inherited his title and estates immediately as there was an uncle "Messire Francois-Adam, Baron d'Holbach, Seigneur de Héeze, Léende et autres Lieux" who lived in the rue Neuve S. Augustin and died in 1753. His funeral was held at Saint-Roch, his parish church, Thursday, September 16th, where he was afterward entombed. [5:6] Holbach was a student in the University of Leyden in 1746 and spent a good deal of time at his uncle's estate at Héeze, a little town in the province of North Brabant (S.E. of Eindhoven). He also traveled and studied in Germany. There are two manuscript letters in the British Museum (Folio 30867, pp. 14, 18, 20) addressed by Holbach to John Wilkes, which throw some light on his school-days. It is interesting to note that most of Holbach's friends were young Englishmen of whom there were some twenty-five at the University of Leyden at that time. [6:7] Already at the age of twenty-three Holbach was writing very good English, and all his life he was a friend of Englishmen and English ideas. His friendship for Wilkes, then a lad of nineteen, lasted all his life and increased in intimacy and dignity. The two letters following are of interest because they are the only documents we have bearing on Holbach's early manhood. They reveal a certain sympathy and feeling--rather gushing to be sure--quite unlike anything in his later writings, and quite out of line with the supposedly cold temper of a materialist and an atheist.

[Footnote: These letters, contrary to modern usage, are printed with all the peculiarities of eighteenth century orthography. It was felt that they would lose their quaintness and charm if Holbach's somewhat fantastic English were trifled with or his spelling, capitalization and punctuation modernized.]

I should not have felt by half enough the pleasure your kind letter gave me, If I had words to express it; I never doubted of your friendship, nor I hope do you know me so little as to doubt of mine, but your letter is full of such favorable sentiments to me that I must own I cannot repay them but by renewing to you the entire gift of my heart that has been yours ever since heaven favour'd me with your acquaintance. I need not tell you the sorrow our parting gave me, in vain Philosophy cried aloud nature was still stronger and the philosopher was forced to yield to the friend, even now I feel the wound is not cur'd. Therefore no more of that--_Hope_ is my motto. Telling me you are happy you make me so but in the middle of your happiness you dont forget your friend, What flattering thought to me! Such are the charms of friendship every event is shar'd and nothing nor even the greatest intervals are able to interrupt the happy harmony of truly united minds. I left Leyden about 8 or 10 days after you but before my departure I thought myself obliged to let Mr Dowdenwell know what you told me, he has seen the two letters Mr Johnson had received and I have been mediator of ye peace made betwixt the 2 parties, I don't doubt but you have seen by this time Messrs Bland & Weatherill who were to set out for Engelland the same week I parted with them. When I was leaving Leyden Mr Vernon happen'd to tell me he had a great mind to make a trip to Spa. So my uncles' estate being on ye road I desir'd him to come along with me, he has been here a week and went on afterwards in his journey, at my arrival here, I found that General Count Palfi with an infinite number of military attendants had taken possession of my uncles' house, and that the 16 thousd men lately come from Germany to strengthen the allies army, commanded by Count Bathiani and that had left ye neighborhood of Breda a few days before and was come to Falkenswert (where you have past in your journey to Spa) one hour from hence. Prince Charles arrived here the same day from Germany to take ye command of the allies, the next Day the whole army amounting to 70thd men went on towards the county of Liège to prevent the French from beseiging Namur, I hear now that the two armies are only one hour from another, so we expect very soon the news of a great battle but not without fear, Count Saxes army being, by all account of hundred ten thoud. men besides. Prince Counti's army of 50 thd. this latter General is now employ'd at the siege of Charleroy, that can't resist a long while, it is a report that the King of France is arrived in his army, I hope this long account will entertain you for want of news papers: Mr. Dowdeswell being left alone of our club at Leyden I Desir'd him to come and spend with me the time of his vacations here, which proposal I hope he will accept and be here next week. What happy triumvirat would be ours if you were to join: but that is impossible at present; however those who cant enjoy reality are fond of feeding their fancies with agreable Dreams and charming pictures; that helps a little to sooth the sorrow of absence and makes one expect with more pati[ence] till fortune allows him to put in execution the cherish'd systems he has been fed upon fore some [time] I shall expect with great many thanks the books you are to send me; it will be for me a dubble pleasure to read them, being of your choice which I value as much as it deserves, and looking at them as upon a new proof of your benevolence, as to those I design'd to get from Paris for you, I heard I could not get them before my uncles' return hither all commerce being stopt by the way betwixt this country and France.

A few days before my departure from Leyden I receiv'd a letter from Mr Freeman from Berlin, he seams vastly pleas'd with our Germany, and chiefly with Hambourg where a beautiful lady has taken in his heart the room of poor Mss. Vitsiavius, my prophesy was just; traveling seems to have alter'd a good deal his melancholy disposition as I may conjecture by his way of writing. He desired his service to you. As to me, Idleness renders me every day more philosopher every passion is languishing within me, I retain but one in a warm degree, viz, friendship in which you share no small part. I took a whim to study a little Physic accordingly I purchased several books in that Way, and my empty hours here are employ'd with them. I am sure your time will be much better employ'd at Alesbury you'll find there a much nobler entertainment Cupid is by far Lovlier than Esculapius, however I shall not envy your happiness, in the Contrary I wish that all your desires be crown'd with success, that a Passion that proves fatal to great many of men be void of sorrow for you, that all the paths of love be spred over with flowers in one Word that you may not address in vain to the charming Mss. M. I am almost tempted to fall in love with that unknown beauty, 't would not be quite like Don Quixotte for your liking to her would be for me a very strong prejudice of her merit, which the poor Knight had not in his love for Dulcinea.

I shall not ask your pardon for the length of this letter I am sure friendship will forgive the time I steal to Love however I cannot give up so easily a conversation with a true friend with whom I fancy to speak yet in one of those delightfull evening walks at Leyden. It is a dream, I own it, but it is so agreable one to me that nothing but reality could be compared to the pleasure I feel: let me therefore insist a little more upon't and travel with my Letter, we are gone! I think to be at Alesbury! there I see my Dear Wilkes! What a Flurry of Panions! Joy! fear of a second parting! what charming tears! what sincere Kisses!--but time flows and the end of this Love is now as unwelcome to me, as would be to another to be awaken'd in the middle of a Dream wherein he is going to enjoy a beloved mistress; the enchantment ceases, the delightfull images vanish, and nothing is left to me but friendship, which is of all my possessions the fairest, and the surest, I am most sincerely Dear Wilkes

Your affectionate friend and humble servant DE HOLBACH Heze the 9th august 1746 N. S.

I shall expect with impatience the letter you are to write me from Alesbury. Will it be here very soon!

HOLBACH TO WILKES [HÉEZE Dec. 3rd. 1746]

During a little voyage I have made into Germany I have received your charming letter of the 8th. September O. S. the many affairs I have been busy with for these 3 months has hindered me hitherto from returning to you as speedy an answer as I should have done. I know too much your kindness for me to make any farther apology and I hope you are enough acquainted with the sincerety of my friendship towards you to adscribe my fault to forgetfulness or want of gratitude be sure, Dear friend, that such a disposition will allways be unknown to me in regard to you. I don't doubt but you will be by this time returned at London, the winter season being an obstacle to the pleasures you have enjoyed following ye Letter at Alesbury during the last Autumn. I must own I have felt a good deal of pride when you gave me the kind assurance that love has not made you forget an old friend, I need not tell you my disposition. I hope you know it well enough and like my friendship for you has no bounds I want expressions to show it. Mr Dowdeswell has been so good as to let me enjoy his company here in the month of August, and returned to Leyden to pursue his studies in the middle of September. We often wished your company and made sincere libations to you with burgundy and Champaigne I had a few weeks there after I set out for Germany where I expected to spend the whole winter but the sudden death of my Uncle's Steward has forced me to come back here to put in order the affairs of this estate, I don't know how long I shall be obliged to stay in the meanwhile I act pretty well the part of a County Squire, id est, hunting, shooting, fishing, walking every day without to lay aside the ever charming conversation of Horace Virgil Homer and all our noble friends of the Elysian fields. They are allways faithfull to me, with their aid I find very well how to employ my time, but I want in this country a true bosom friend like my dear Wilkes to converse with, but my pretenssions are too high, for every abode with such a company would be heaven for me.

Cushing's study opens with Diderot's 1771 letter to Princess Dashkoff, which frames the century's spirit as one of liberty, attacking religion as the first barrier to fall. This epigraph sets the stage for a work that is itself structured as a doctoral dissertation, with a detailed table of contents dividing the subject into three chapters: Holbach the man, his works, and the Système de la Nature. The book moves from biography to bibliography to philosophical analysis, a progression that mirrors the author's methodical approach.

The excerpts reveal a recurring pattern: Cushing juxtaposes Holbach's ideas with the reactions of his contemporaries. Voltaire's harsh condemnation of the Système as "un chaos" and "un grand mal moral" is set against Goethe's dismissal of it as "grau" and "cimmerisch." This dialectical structure, moving between text and response, gives the study its analytical momentum.

A Dissertation's Architecture

The book's structure is immediately visible in its detailed table of contents, which lists chapters, an appendix of unpublished letters, and a two-part bibliography. This academic framework is not merely formal; it shapes how Cushing presents his evidence. Chapter I, "Holbach the Man," draws on early letters to John Wilkes and relationships with Diderot, Rousseau, Hume, and Garrick to construct a portrait. Chapter II catalogs Holbach's works, distinguishing translations of German scientific texts and English deists from original atheistic tracts like Le Christianisme devoilé and Théologie portative. Chapter III then focuses entirely on the Système de la Nature, its philosophy, and its refutations.

This tripartite structure allows Cushing to move from personal context to textual analysis, but it also means that the philosophical core is reached only after extensive biographical and bibliographical groundwork. Readers should note how the author uses the appendix—five unpublished letters to John Wilkes—as a primary source to support claims about Holbach's character and network.

Recurring Images of Attack and Defense

A striking image recurs throughout the excerpts: the assault on religion as a violent, unstoppable attack. Diderot's letter speaks of giving "l'assaut à la barrière de la religion" and turning "regards menaçants" from heaven to earthly sovereignty. Cushing picks up this martial language, describing Holbach's work as part of an "attack on religion that preceded and helped to prepare the French Revolution." The metaphor of breaking barriers and directing threats appears again in Voltaire's reaction, where he calls the Système "un ouvrage de ténèbres" and "un péché contre la nature."

This imagery of assault and defense is mirrored in the list of refutations Cushing provides—eleven works explicitly directed against the Système de la Nature, from Abbé Rive's Lettres philosophiques to Frederick II's Examen critique. The study thus presents intellectual history as a battlefield, with Holbach's materialism as the target of a coordinated counterattack.

Movement Between Circles: Paris and Strasbourg

Cushing's narrative moves between two distinct intellectual circles: Holbach's Parisian salon, frequented by Diderot, Rousseau, and Hume, and the university circle at Strasbourg where Goethe encountered the Système de la Nature. The contrast is sharp. In Paris, Voltaire's letters seethe with bitterness; he accuses Holbach's circle of "caresser les gens en place, et d'abandonner ceux qui n'y sont plus." In Strasbourg, Goethe and his peers find the book "harmless and uninteresting," its atheistic twilight casting a veil over the beauty of the earth.

This geographical and generational shift highlights a key tension in the study: the same text that provoked Voltaire's fury was dismissed by young romantics as "die echte Quintessenz der Greisenheit"—the true quintessence of old age. Cushing uses this juxtaposition to illustrate the rapid romantic reaction that obscured the clarity of eighteenth-century issues. The movement between these scenes gives the study a dynamic, comparative quality.

The Weight of the Bibliography

The bibliography occupies a prominent place in the book's structure, divided into two parts: editions of Holbach's works in chronological order and a general bibliography. This is not a mere appendix; it reflects Cushing's method of building his argument on a foundation of primary and secondary sources. The list of refutations alone—eleven titles with full publication details, including prices like "40 sols broché"—demonstrates a meticulous attention to the material history of ideas.

Readers should pay attention to how Cushing uses these bibliographic details to support his claims. For example, the inclusion of Frederick II's Examen critique among the refutations signals the political stakes of Holbach's atheism. The bibliography also serves as a roadmap for further research, listing works by Bergier, Castillon, and others that Cushing engages with in the text. This scholarly apparatus is integral to the study's argument, not a decorative afterthought.

Cushing's study is best approached as a work of intellectual history that privileges documentation over narrative. The detailed table of contents and extensive bibliography reward readers who follow the footnotes and endnotes. Pay particular attention to the appendix of unpublished letters, which offers direct access to Holbach's voice. The book's value lies less in its conclusions than in the network of sources it assembles—a network that reveals how radical ideas traveled through letters, refutations, and salons in the decades before the French Revolution.

Reading about Holbach’s quiet certainty among his fierce friends, I kept thinking how some ideas just settle in you, unasked. Later, I found a gentle companion in The World's Greatest Books — Volume 14 — Philosophy and Economics — Story, Setting & Ideas, where old thoughts feel less like arguments and more like shared rooms we can sit in. That lingering stayed with me.

    {'content': "An insightful biography that brings to life the radical thinker Baron d'Holbach, a central figure of the French Enlightenment. The book richly details his contributions to atheism, materialism, and political philosophy, placing him in the turbulent context of 18th-century France. The author's scholarship is impeccable, making this an essential read for anyone interested in the history of radical thought and the intellectual foundations of modernity."}

    {'content': "This study of d'Holbach offers a solid overview of his life and ideas, with good historical context. The book is well-researched but at times reads more like a dry academic monograph, lacking narrative flair. Nevertheless, if you're seeking a comprehensive account of this important yet often overlooked thinker, this is a reliable source."}

    Michael Howard - 2 weeks ago
    {'content': "The book fails to make d'Holbach's philosophy engaging; the prose is stilted and the analysis superficial. It reads like a long list of facts and sources, without a compelling thesis or fresh insights. For a figure as radical and interesting as d'Holbach, this biography is disappointingly dull, offering only a surface-level account that neglects the intellectual ferment of the era."}
