In the alarm caused by the invasion he urged a bold and resolute policy. He was a member of the Convention and of the Committee of Public Safety. At the crisis of the struggle with Robespierre, Danton declined to strike the first blow and disdained to fly. Arrested March, 1794, he said when interrogated by the judge, “My name is Danton, my dwelling will soon be in annihilation; but my name will live in the Pantheon of history.” He maintained his lofty bearing on the scaffold, where he perished 5 April, 1794.

In ’39 he married, and in ’42 left London and settled at Down, Kent. His studies, combined with the reading of Lamarck and Malthus, led to his great work on The Origin of Species by means of Natural Selection, ’59, which made a great outcry and marked an epoch. Darwin took no part in the controversy raised by the theologians, but followed his work with The Fertilisation of Orchids, ’62; Cross and Self Fertilisation of Plants, ’67; Variations of Plants and Animals under Domestication, ’65; and in ’71 The Descent of Man and Selection in relation to Sex, which caused yet greater consternation in orthodox circles. The following year he issued The Expression of the Emotions of Men and Animals. He also published works on the Movements of Plants, Insectivorous Plants, the Forms of Flowers, and Earthworms. He died 19 April, 1882, and was buried in Westminster Abbey, despite his expressed unbelief in revelation. To a German student he wrote, in ’79, “Science has nothing to do with Christ, except in so far as the habit of scientific research makes a man cautious in admitting evidence. For myself I do not believe that there ever has been any revelation.” In his Life and Letters he relates that between 1836 and 1842 he had come to see “that the Old Testament was no more to be trusted than the sacred books of the Hindoos.” He rejected design and said “I for one must be content to remain an Agnostic.”

De Roberty (Eugene). See Roberty.

Desbarreaux (Jacques Vallée), Seigneur, French poet and sceptic, b. Paris, 1602, great-nephew of Geoffrey Vallée, who was burnt in 1574. Many stories are related of his impiety, e.g. the well-known one of his having a feast of eggs and bacon. It thundered, and Des Barreaux, throwing the plate out of window, exclaimed, “What an amount of noise over an omelette.” It was said he recanted and wrote a poem beginning, “Great God, how just are thy chastisements.” Voltaire, however, assigns this poem to the Abbé Levau. Died at Chalons, 9 May, 1673.

Descartes (René), French philosopher, b. at La Haye, 31 March, 1596. After leaving college he entered the army in ’16, and fought in the battle of Prague. He travelled in France and Italy, and in ’29 settled in Holland. In ’37 he produced his famous Discourses upon the Method of Reasoning Well, etc., and in ’41 his Meditations upon First Philosophy. This work gave such offence to the clergy that he was forced to fly his country “parce qu’il y fait trop chaud pour lui.” He burnt his Traite du Monde (Treatise on the World) lest he should incur the fate of Gallilei. Though a Theist, like Bacon, he puts aside final causes. He was offered an asylum by Christina, Queen of Sweden, and died at Stockholm 11 Feb. 1650.

He became correspondent of Voltaire, Rousseau, d’Alembert, Helvetius, and other philosophers. “Ce prêtre athée,” as Ad. Franck calls him, was the author of a treatise entitled La Vérité, ou le Vrai Système, in which he appears to have anticipated all the leading ideas of Hegel. God, he says, as separated from existing things, is pure nothingness. An analysis of his remarkable work, which remained in manuscript for three-quarters of a century, has been published by Professor Beaussire (Paris, 1855). Died at Montreuil-Bellay, 19 April 1774.

Deslandes (André François Boureau), b. Pondichery, 1690.

His Pygmalion, a philosophical romance, was condemned by the parliament of Dijon, 1742. His Reflexions sur les grands hommes qui sont mort en Plaisantant (Amsterdam, 1732) was translated into English and published in 1745 under the title, Dying Merrily. Another work directed against religion was On the certainty of Human Knowledge, a philosophical examination of the different prerogatives of reason and faith (London, 1741). Died Paris, 11 April, 1757.

Des Maizeaux (Pierre), miscellaneous writer, b. Auvergne, 1673. He studied at Berne and Geneva, and became known to Bayle who introduced him to Lord Shaftesbury, with whom he came to London, 1699. He edited the works of Bayle, Saint Evremond and Toland, whose lives he wrote, as well as those of Hales and Chillingworth. Anthony Collins was his friend, and at his death left him his manuscripts. These he transferred to Collins’s widow and they were burnt. He repented and returned the money, 6 Jan. 1730, as the wages of iniquity.

Desmoulins (Lucié Simplice Camille Benôit), French revolutionary writer, b. Guise, 2 March, 1760. He was a fellow-student of Robespierre at Paris, and became an advocate and an enthusiastic reformer. In July ’89 he incited the people to the siege of the Bastille, and thus began the Revolution. On 29 Dec. 1790 he married Lucile Laridon-Duplessis. He edited Le Vieux Cordelier and the Révolutions de France et de Brabant, in which he stated that Mohammedanism was as credible as Christianity. He was a Deist, preferring Paganism to Christianity. Both creeds were more or less unreasonable; but, folly for folly, he said, I prefer Hercules slaying the Erymanthean boar to Jesus of Nazareth drowning two thousand pigs. He was executed with Danton, 5 April 1794. His amiable wife, Lucile, who was an Atheist (b. 1770), in a few days shared his fate (April 13). Carlyle calls Desmoulins a man of genius, “a fellow of infinite shrewdness, wit—nay, humor.”

Des Periers (Jean Bonaventure), French poet and sceptic, b. Arnay le Duc, about 1510. He was brought up in a convent, only to detest the vices of the monks.

He probably knew Rabelais, whom he mentions as “Francoys Insigne.” Attached to the court of Marguerite of Valois, he defended Clement Marot when persecuted for making a French version of the Psalms. He wrote the Cymbalum Mundi, a satire upon religion, published under the name of Thomas de Clenier à Pierre Tryocan, i.e., Thomas Incrédule à Pierre Croyant, 1537. It was suppressed and the printer, Jehan Morin, imprisoned. Des Periers fled and died (probably by suicide, to escape persecution) 1544. An English version of Cymbalum Mundi was published in 1712. P. G. Brunet, the bibliographer, conjectures that Des Periers was the author of the famous Atheistic treatise, The Three Impostors.

Deubler (Konrad). The son of poor parents, b. Goisern, near Ischl, Upper Austria, 26 Nov. 1814. Self-taught amid difficulties, he became the friend of Feuerbach and Strauss, and was known as “the Peasant Philosopher.” In 1854 he was indicted for blasphemy, and was sentenced to two years’ hard labor and imprisonment during pleasure. He was incarcerated from 7 Dec. ’54, till Nov. ’56 at Brünn, and afterwards at Olmutz, where he was released 24 March, 1857. He returned to his native place, and was visited by Feuerbach.

Diagoras, Greek poet, philosopher, and orator, known as “the Atheist,” b. Melos. A pupil of Democritus, who is said to have freed him from slavery. A doubtful tradition reports that he became an Atheist after being the victim of an unpunished perjury. He was accused (B.C. 411) of impiety, and had to fly from Athens to Corinth, where he died. A price was put upon the Atheist’s head. His works are not extant, but several anecdotes are related of him, as that he threw a wooden statue of Hercules into the fire to cook a dish of lentils, saying the god had a thirteenth task to perform; and that, being on his flight by sea overtaken by a storm, hearing his fellow-passengers say it was because an Atheist was on board, he pointed to other vessels struggling in the same storm without being laden with a Diagoras.

Diderot (Denis), French philosopher, b. Langres, 6 Oct. 1713. His father, a cutler, intended him for the Church. Educated by Jesuits, at the age of twelve he received the tonsure. He had a passion for books, but, instead of becoming a Jesuit, went to Paris, where he supported himself by teaching and translating. In 1746 he published Philosophic Thoughts, which was condemned to be burnt. It did much to advance freedom of opinion. Three years later his Letters on the Blind occasioned his imprisonment at Vincennes for its materialistic Atheism. Rousseau, who called him “a transcendent genius,” visited Diderot in prison, where he remained three years. Diderot projected the famous Encyclopédie, which he edited with Alembert, and he contributed some of the most important articles. With very inadequate recompense, and amidst difficulties that would have appalled an ordinary editor, Diderot superintended the undertaking for many years (1751–65). He also contributed to other important works, such as Raynal’s Philosophic History, L’Esprit, by Helvetius, and The System of Nature and other works of his friend D’Holbach. Diderot’s fertile mind also produced dramas, essays, sketches, and novels. Died 30 July, 1784. Comte calls Diderot “the greatest thinker of the eighteenth century.”

Dippel (Johann Konrad), German alchemist and physician, b. 10 Aug. 1672, at Frankenstein, near Darmstadt. His Papismus vapulans Protestantium (1698) drew on him the wrath of the theologians of Giessen, and he had to flee for his life. Attempting to find out the philosopher’s stone, he discovered Prussian blue. In 1705 he published his satires against the Protestant Church, Hirt und eine Heerde, under the name of Christianus Democritos. He denied the inspiration of the Bible, and after an adventurous life in many countries died 25 April, 1734.

He was acquainted with Rabelais, Des Periers, and other advanced men of the time. In 1543 the Parliament condemned his books to be burnt, and in the next year he was arrested on a charge of Atheism. After being kept two years in prison he was strangled and burnt, 3 Aug. 1546. It is related that seeing the sorrow of the crowd, he said: “Non dolet ipe Dolet, sed pia turba dolet.”—Dolet grieves not, but the generous crowd grieves. His goods being confiscated, his widow and children were left to beggary. “The French language,” says A. F. Didot, “owes him much for his treatises, translations, and poesies.” Dolet’s biographer, M. Joseph Boulmier, calls him “le Christ de la pensée libre.” Philosophy has alone the right, says Henri Martin, to claim Dolet on its side. His English biographer, R. C. Christie, says he was “neither a Catholic nor a Protestant.”

With Helmholtz he has done much to establish the new era of positive science, wrongly called by opponents Materialism. Du Bois-Reymond holds that thought is a function of the brain and nervous system, and that “soul” has arisen as the gradual results of natural combinations, but in his Limits of the Knowledge of Nature, ’72, he contends that we must always come to an ultimate incomprehensible. Du Bois-Reymond has written on Voltaire and Natural Science, ’68; La Mettrie, ’75; Darwin versus Galiani, ’78; and Frederick II. and Rousseau, ’79.

She corresponded for many years with Horace Walpole, D’Alembert and Voltaire. Many anecdotes are told of her; thus, to the Cardinal de Polignac, who spoke of the miracle of St. Denis walking when beheaded, she said “Il n’y a que le premier pas qui coûte.” Died 24 Sept. 1780. To the curé of Saint Sulpice, who came to her death-bed, she said “Ni questions, ni raisons, ni sermons.” Larousse calls her “Belle, instruite, spirituelle mais sceptique et materialiste.”
