‎First printing of a series of influential papers by Leibniz, Jacob Bernoulli and Johann Bernoulli.First publication of Jakob Bernoulli's famous and influential ""Bernoulli Equation"". In ""Notatiuncula Constructiones Lineae"" Bernoulli proposed a solution to non linear equations which today is one of the most common used solutions of the general fluid. Bernoulli equations are significant because they are nonlinear differential equations with known exact solutions. In the ""Specimen dynamicum"" Leibniz presents a conception of body and force which distinct between primitive and derivative forces and between active and passive forces. This article is regarded as being the clearest exposition of Leibniz' dynamics. (DSB VII, 151b).""The first attempt at a detailed account of the dynamics was a long dialogue, the ""Phoranomus seu de potentia et legibus naturae,"" written in July 1689 while Leibniz was in Rome. This was quickly followed be the composition of the massive Dynamica de potential et legibus naturae corporeae (1689-90) [...]. Though it was written with the intention of publication, and though Leibniz work at publishing it, he never considered it entirely finished and it remained unpublished during his lifetime.The later [...] he finally revealed some of the metaphysical foundations of the project in an essay [the present paper]."" (Garber, Daniel. Leibniz: body, substance, monad. 2009. 132 p.)""Its title suggests a summary of or a selection from the earlier work [...]. However, it actually contains something in a way rather more interesting: a careful exposition of the metaphysical foundations of the new science, something that is hard to find in the old Dynamica or any of the more Technical pieces."" (Garber, Daniel. Leibniz: Body, Substance, Monad. 2009. 133 p.)‎

‎Rare third German edition. Last Richter-edition. First published in French in 1710. It is the only larger philosophical work, Leibnitz himself published and it is a work of immense importance to philosophy, theology and mathematics. In this work Leibniz represents his excellent calculating machine, which has served as the basis for what we now call a computer, as he presents the binary arithmetic, ""Rechnen mit Null und Eins"" (""calculating with zero and one"") in the Beylage (p. 926), which forms the basis for the much later developed computer science (see PMM 177). This work contains ""Anmerkungen"" by Richter and ""Lebens=Beschreibung"" by Fontenelle, followed by ""Beylage"". In these ""Beylage"" we find the method of converting numbers into the binary system, which here is said to be ""etwas recht neues, welches der Herr Leibnitz zu Hanover erfunden"" (""something brand new, which Mr. Leibnitz von Hanover has discovered"") as well as ""Eine Schrift. In welcher klar gezeiget wird/ dass nicht Herr Neuton,sondern der Herr von Leibnitz Erfinder des CALCULI DIFFERENTIALIS sey."" (A Treatise. In which it is clearly shown/ that Mr. Leibniz and not Mr. Newton is the inventor of the CALCULI DIFFERENTIALIS"").All early editions of the Theodicee are rare. See D.S.B.: VIII, pp. 161-166.‎

‎First edition thus, being the first collected edition of Leibnitz' philosophical works in French and Latin, and containing the FIRST PRINTING of one of Leibnitz' most important philosophical works, his ""Nouveaux essays sur l'entendement humain"" (New Essays on Human Understanding), in which he attacks and refutes Locke and his ""Essay on Human Understanding"" and gives important testimony to his own philosophical ideas. With its 496 pages, this extensive work takes up most of this collection of philosophical works, and it also constitutes one of his largest and most important of his philosophical works. As explained by Raspe, the editor, in his preface to this publication, ""LES NOUVEAUX ESSAIS SUR L'ENTENDEMENT HUMAIN, qui sont la partie principale de recueil, sont connûs trés imparfaitement par l'histoire de la Philosophie de Leibnitz, que Mr. Ludovici a publiée"" (p. X), and the reason why the work was known, even though it had not been published, is because of a letter that Leibnitz had written in 1714, in which he explains why he did not wish to publish the work. Raspe quotes the letter (p. X), from which it becomes clear that Leibnitz had not wished to publish an attack on Locke and his work, because Locke had died in 1704 (the same year that Leibnitz had actually written the work), and because Leibnitz was against publishing refutations of dead authors: ""Mais je me suis degouté de publier des refutations des Auteurs morts, quoiqu'elles dissent paroitre Durant leur vie & étre communiqués à eux memes"". Raspe points to the nobleness of this decision, but he also points to what could be other reasons for Leibnitz not wishing to publish his seminal work, one of them being that towards the end of his life (he died in 1716), he did not wish to enter into any more controversies with the British, since he was already engaged in two very important ones that occuopied much of his time and energy: The first concerned the invention of the differential calculus, the second was against Mr. Clarke on liberty and important metaphysical and theological questions. Another reason could also be that he did not want to begin controversies with the friends of Locke, who at that time were many and important.Locke's ""An Essay Concerning Human Understanding"", which is the work here being refuted by Leibnitz, became the crucial groundwork for the future empiricists with David Hume in the foreground, and thus Leibnitz' work, though published posthumously, probably came to play a bigger role in the history of philosophy than it would have done had it been published just after he wrote it. Few philosophers of his time were susceptible to Leibnitz' ideas and his application of logic to the problems of metaphysics, as most of them were far more receptive to Locke's empiricism. However, when Leibnitz' ""Nouveaux essays..."" was finally published here in his ""Oeuvres philosophiques"" in 1765, it became hugely influential and was also an important factor in the development of Kant's transcendental philosophy.The hugely famous work by Locke, in which he stated his famous theory that the mind of the newborn is like a blank slate (tabula rasa) and concluded that all ideas come from experience and that there are no such things as innate principles, was generally sharply criticized by the rationalists, the most important of them being Leibnitz. Leibnitz' response, his ""Les nouveaux essays sur l'entendement humain"" constitutes the most important of the rationalist responses and it is written in the form of a chapter-by-chapter refutation. He refutes the major premise of Locke's work, that the senses are the source of all understanding, primarily by adding to this ""except the understanding itself"", thus going on to distinguish between his three levels of understanding, which are part of the centre of his philosophy.For Leibnitz as well as for Locke the great inspiration was Descartes, but they chose two fundamentally different directions, Locke the materialistic one and Leibnitz the idealistic one. The present work represents the greatest clash between the two giants of late 17th century philosophy. The effect of Leibnitz' work was enormous, and among the Germans he invoked a great passion for philosophical studies. Leibnitz represents a striking contrast to both Locke with his empiricism and Spinoza. One earlier collection of some of Leibnitz' works had been printed before this one, but it did not contain his ""New Essays on Human Understanding"", and only consisted of his ""Smaller Philosophical Works"". This is the German 1740-edition ""Kleinere philosohische Schriften"". The other writings contained in this publication are ""Examen du sentiment du P. Malebranche que nous voyons tout en Dieu"", """"Dialogus de connexione inter res & verba"", ""Difficultates quaedam Logicae"", ""Discours touchant la methode de la certitude & de l'art d'inventer"", ""Historia et commendatio charactericae universalis quae simul sit ars inveniendi"".Graesse IV:152. ‎
