chair of dogmatic theology. Published works In 1679 in Saumur were published Liberii de Sancto Amore Epistolae Theologicae (Irenopoli: Typis Philalethianis), usually attributed to Leclerc. They deal with the doctrine of the Trinity, the Hypostatic union of the two natures in Jesus Christ, original sin, and other topics, in a manner unorthodox for the period. In 1685 he published with Charles Le Cène Entretiens sur diverses matières de théologie. In 1685 he published Sentimens de quelques theologiens de Hollande sur l'histoire critique du Vieux Testament composée par le P. Richard Simon, in which, while pointing out what he believed to be Richard Simon's faults, he advanced views of his own. These included: arguments against the Mosaic authorship of the Pentateuch; his views as to the manner in which the five books were composed; and his opinions on the subject of divine inspiration in general, in particular on the Book of Job, Book of Proverbs, Ecclesiastes, and Canticles. Simon's Réponse (1686) drew from Le Clerc a Defence des sentimens in the same year, which was followed by a new Réponse (1687). In 1692 appeared his Logica sive Ars Ratiocinandi, and also Ontologia et Pneumatologia; these, with the Physica sive de rebus corporeis (1696), are incorporated with the Opera Philosophica, which have passed through several editions. In his Logica, Le Clerc rewrites the Catholic Port-Royal Logique from a protestant Remonstrant perspective and supplements the Logique with analyses taken from Essay of his friend, John Locke. In turn, Charles Gildon published a partial and unattributed translation of Le Clerc's Logica as the treatise "Logic; or, The Art of Reasoning" in the second (1712) and subsequent editions of John Brightland's Grammar of the English Tongue. In 1728, Ephraim Chambers used Gildon's translation of Le Clerc's version of the Port-Royal Logique as one of his sources when he compiled his Cyclopaedia. John Mills and Gottfried Sellius later translated Chambers's Cyclopaedia into French. Their translation was appropriated by Denis Diderot and Jean le Rond d'Alembert as the starting point for their Encyclopédie. In particular, the article on définition (1754) in the Encyclopédie can be traced through this chain of writers, editors, translators, and compilers to the Port-Royal Logique through the Logica of Jean Le Clerc. In 1693 his series of Biblical commentaries began with that on the Book of Genesis; the series was not completed until 1731. The portion relating to the New Testament books included
