About this ebook
Philosophical Thoughts (Pensées philosophiques) is one of Diderot's earliest and most provocative works, written in the form of aphorisms. In this text, Diderot grapples with questions of faith, reason, and morality, often questioning the dominant religious and philosophical orthodoxies of his time. He critiques superstition and blind faith, advocating instead for a rational and skeptical approach to understanding the world. The work also shows Diderot's fascination with the conflict between materialism and spirituality, as he studies the consequences of a universe governed by natural laws rather than divine intervention. Philosophical Thoughts was controversial upon its publication and even led to Diderot's imprisonment for a time, as it was seen as a direct challenge to religious authority. Despite its brevity, the work is a cornerstone of Diderot's early intellectual development and a precursor to his later, more expansive philosophical inquiries. Diderot's voice in this early work does not yet carry the full thrum of his later atheism, but it hums with an unmistakable friction against dogma. Already, Diderot was in open conflict with his overly religious brother, whom he openly hated, driving his philosophy towards an unanchored Materialism. The supporting apparatus for Philosophical Thoughts comprises a new Afterword by the translator, a short biography, a glossary of Philosophical Terms used by Diderot, a chronology of his core life and works, and a summary index of all of Diderot's works. This edition translates Philosophical Thoughts from Diderot's Enlightenment-era French into contemporary English while retaining its intellectual context. Diderot's Philosophical Thoughts, written between Good Friday and Easter Monday of 1746, earned him 50 louis, intended for his companion Madam de Puisieux, whose demands spurred his productivity. Condemned to burning by Parliament in July 1746, the work's first edition (adorned with an elegant frontispiece of Truth unmasking a fallen Superstition) survived symbolically, as authorities often burned substitutes. It sparked immediate controversy, resurfacing in altered forms: a 1757 edition titled New Year's Gifts to Free Thinkers, falsely attributed editions (including one to Voltaire), and international reprints with dubious notes or appendices, like the 1777 bilingual edition paired with a fictional dialogue. Critics pounced: La Mettrie denied authorship when Diderot's text was wrongly ascribed to him; Formey's Rational Thoughts (1749) rebutted the ideas, mocked by Voltaire; Jesuit Father Senemaud's 1756 parody drew Grimm's ire; and a 1761 Hague edition parroted Diderot's arguments in reverse. Abbé Ilharat de la Chambre dismissed the work as "dangerous" in his Letters (1749), urging Diderot to read his own Treatise on True Religion, ironic, as Diderot had already cited it. Anti Encyclopedist pamphleteers like Palissot seized on the text, attacking its deist leanings. While Diderot here rejects orthodox religion, he remains a deist, echoing Bayle's skepticism by presenting opposing arguments without resolution, seen in his case against atheism (Thoughts xxii, xxiii) and a fleeting, unconvincing nod to Catholic doctrine (Thought lviiith). Though later portrayed by Naigeon as free of "superstitious matter," the Thoughts reveal a transitional thinker, balancing critique and belief, leaving readers to choose their path without any real resolution to the angry, reactionary and polemic worldview Diderot developsDiderot's skeptical method operates asymmetrically throughout the text, rigorously applied to religious claims while more tentatively directed toward emerging naturalistic explanations. This methodological inconsistency shows his transitional philosophical position. In aphorism 15, he writes: "Skepticism is the touchstone by which truth must be tested; it reveals both authentic certitude and mere prejudice." Yet his application of this skeptical principle varies in intensity, suggesting an intellectual trajectory still in motion. The evidence from his private correspondence during this period confirms this reading, in a letter to Voltaire dated June 1746, Diderot acknowledges "following evidence toward conclusions that remain unsettled in my mind."
