Leibniz: Works

An English translation of Leibniz's fragment "Horizon rerum humanarum... " in which he announces a plan to demonstrate "that the number of truths or falsehoods enunciable by humans as they are now is limited; and also that if the present condition of humanity persisted long enough, it would happen that the greatest part of what they would communicate in words, whether by talking or writing, would have to coincide with what others have already communicated in the past; and moreover that (...) new humans would lead an entire life that appears thoroughly the same to the senses as lives that others have already led." .

An English translation of a draft essay by Leibniz from 1715, in which Leibniz argues for the conclusion: "if humanity endured long enough in its current state, a time would arrive when the same life of individuals would return, bit by bit, through the very same circumstances. I myself, for example, would be living in a city called Hannover located on the Leine river, occupied with the history of Brunswick, and writing letters to the same friends with the same meaning.".

This paper addresses some issues of Leibniz’s metaphysics to show the relationship between religion, God, and the conception of eternal truths, and with that to reveal that Leibniz’s philosophy is a coherent and intertwined whole. His idea of religion is set out briefly, then his metaphysics is analyzed, in particular creation and what are the eternal truths. The paper ends with a commentary on some quotations from the New essays that make evident that these truths require the existence of God. (...) // Se abordan algunas cuestiones de la metafísica leibniziana para mostrar el vínculo entre la religión, Dios y la concepción de las verdades eternas, y con ello poner de manifiesto que la filosofía de Leibniz es un todo engarzado y coherente. Se expone sucintamente su idea de religión, se analiza su metafísica, en particular la creación y lo que son las verdades eternas, y finalmente se comentan algunas citas de los Nuevos ensayos que evidencian que dichas verdades exigen la existencia de Dios.

Through the reconstruction of Leibniz's theory of the degrees of knowledge, this e-book investigates and explores the intrinsic relationship of imagination with space and time. The inquiry into this relationship defines the logic of imagination that characterizes both human and non-human animals, albeit differently, making them two different species of imaginative animals. -/- Lucia Oliveri explains how the emergence of language in human animals goes hand in hand with the emergence of thought and a different form of rationality constituted by (...) logical inferences based on identity and contradiction, principles that are out of reach of the imagination. The e-book concludes that the presence of innate principles in human animals transforms the way in which they sense-perceive the world, thereby constantly increasing the distinction between human and non-human animals. -/- Keywords: human and non-human animals, Leibniz and Locke on ideas, Leibniz on bodies, Leibniz on conceivability, Leibniz on degrees of knowledge, Leibniz on degrees of perception, Leibniz on innate ideas, Leibniz on modality, Leibniz on similarity and congruence, Leibniz on space and time, Leibniz’s philosophy of language, theory of types.

Rita Widmaier and Malte-Ludolf Babin have done a valuable scholarly service for studies of the early modern European reception of China in collecting letters from Leibniz's extensive correspondence concerning China and translating them from the original Latin and French into German. This multi-lingual and chronologically organized edition gathers letters to and from Leibniz as well as supplementary texts composed between the years 1694 and 1716. It incorporates helpful clarificatory notes as well as an informative and lucid introduction.This edition focuses on (...) the exchanges between Leibniz and the Jesuit theologian and philosopher Barthélemy Des Bosses S.J. and other Jesuits in Europe who were in...

Leibnizian metaphysics is traditionally held to be idealistic. It means that reality is composed of soul-like substances whereas material bodies are mere phenomena. The traditional interpretation presupposes that Leibniz’s view has not changed during the mature period (from 1683 onward). Some commentators have recently challenged this view. They claim that either Leibniz (despite inconsistency) was both a realist and an idealist (Hartz), or changed his view on the nature of substance (Garber). The aim is to defend the traditional interpretation and (...) to reply to the arguments by realist commentators. (shrink)

A fresh translation and in-depth commentary of Leibniz's seminal text, the Monadology. -/- Written in 1714, the Monadology is widely considered to be the classic statement of Leibniz's mature philosophy. In the space of 90 numbered paragraphs, totalling little more than 6000 words, Leibniz outlines - and argues for - the core features of his philosophical system. Although rightly regarded as a masterpiece, it is also a very condensed work that generations of students have struggled to understand. -/- Lloyd Strickland (...) presents a new translation of the Monadology, alongside key parts of the Theodicy, and an in-depth, section-by-section commentary that explains in detail not just what Leibniz is saying in the text but also why he says it. The sharp focus on the various arguments and other justifications Leibniz puts forward makes possible a deeper and more sympathetic understanding of his doctrines. (shrink)

Leibniz’s short letter to the mathematician and physicist Ludovico Casati of 1689 is a short but interesting text on the Principle of Identity of Indiscernibles, to which it is entirely dedicated. Since there is no watermark in the paper of the letter, the letter is difficult to date, but it is likely that it was written during Leibniz’s stay in Rome, sometime between April and November of 1689 (A 2 2 287–8). When addressing the letter, Leibniz wrote ‘Casani’, but this (...) seems to be a mistake and the real addressee is thought to be Ludovico Casati, nephew of Paolo Casati, the Jesuit mathematician. The letter, reproduced in the Berlin’s Academy edition of Leibniz’s works, was first published by Gerhardt in the Archiv für Geschichte der Philosophie in 1892 (Gerhardt 1892: 53–54). It also appears in Robinet’s Iter Italicum (Robinet 1988: 134–35). But neither Gerhardt nor Robinet provide a philosophical discussion of the letter, and I am not aware of any other philosophical discussion of it. Furthermore, as far as I know, the letter has never been translated into any language. Thus I shall here provide a transcription (from A 2 2 288–89) and a translation of the letter into English, and a philosophical discussion of its treatment of the Identity of Indiscernibles.

LEIBNIZ AND THE TWO SOPHIES is a critical edition of all of the philosophically important material from the correspondence between the philosopher Gottfried Wilhelm Leibniz (1646-1716) and his two royal patronesses, Electress Sophie of Hanover (1630-1714), and her daughter, Queen Sophie Charlotte of Prussia (1668-1705). In this correspondence, Leibniz expounds in a very accessible way his views on topics such as the nature and operation of the mind, innate knowledge, the afterlife, ethics, and human nature. The correspondence also contains the (...) only known philosophical writings by Sophie and Sophie Charlotte, and thus provides a valuable insight into their views and concerns, as well as throwing light on their characters. The texts are accompanied by a substantial introductory essay which sets the context for the correspondence and analyzes its main philosophical themes. (shrink)

This volume contains more than 60 original translations of papers written by the German philosopher Gottfried Wilhelm Leibniz (1646-1716). As well as contributing to Leibniz scholarship, it is intended to function as an introductory text for students.

Letters exchanged by scientists are a crucial source by which to trace the process that accompanies their scientific evolution. In this paper -accomplished through a historical approach- I aim to throw new light on Leibniz's continuing interest in classical geometry and to stress the significance of his correspondence with the Italian mathematician Vitale Giordano.
