The article presents the various phases in which one of the most eminent journals of the history of philosophy, the Archiv für Geschichte der Philosophie (1888–), dealt with Leibniz’s philosophy and his intellectual legacy. In particular, this study compares the main moments of historiographical interest and disinterest for this subject to the specific attitudes of the journal during the long 20th century.

During the 19th and the 20th century the concept of system undergoes significant transformations. The interplay of biology and sociology gives rise to an olistic definition of the concept, in order to understand society by means of schemes developed in the field of theoris of organisms. It is possible to follow this development from Pareto and Henderson, to Parsons, and finally to Luhmann, by examining the various biological models to which they refer.

To avoid the mystical rapture that seizes interpreters put before the theme of unitas oppositorum in Cusanus and Leibniz, this contribution shall move from the prosaic question: what does ensue from such opposites or from their conjunction? 2) interweave the analysis with some external point of view, notably that of Erasmus. This question will be investigated on the background of two antitethical traditions in dealing philosophically with opposition and contradiction, although in the end we shall try and find out other (...) ways and reasons for connecting the two thinkers on the ground of the various possible unitates oppositorum, than those of the metaphysical doctrine of the opposites.

Ludovico Geymonat was the most important philosopher of science in 20th-century Italy, but he also engaged in the Liberation War and in political activity. Here the first part of his career, when his activity was mostly based in Turin, is aketched, and an overall balance is suggested.

Leibniz participates in a quite important thought tradition of christian Europe, that of concordia between Christians, or between religions. With him this heritage is universalised: the globalization of concordia gives birth to Leibniz’s harmony of universal truth, that the whole of humankind can access.

It is well known that Peano had a reluctant attitude towards philosophy, including philosophy of mathematics. Some scholars have suggested the existence of an 'implicit' philosophy, without being able to describe it. In this paper a first attempt is done to reconstruct, if not a general philosophy of mathematics, at least Peano' epistemology of mathematics and its relation to contemporary positions.

The paper (an ample reworking of a 2005 Italian paper) tries to evaluate Leibniz’s enduring fascination with Spinoza and presents an overview in five stages of the development of his complex relationship to his thought, beginning with the time of Mainz, when Leibniz shows a strange urgency to get in epistolary contact with the author of the Theologico-Political Treatise, despite his public rejection of both the work and the author; then Leibniz’s stay in Paris, especially in the year 1675, when (...) he seeks information through Tschirnhaus on Spinoza’s clandestine doctrines; their personal meeting in the Hague, towards the end of the year 1676, and the subsequent distancing of Leibniz from Spinozism; the reading by Leibniz of Spinoza’s Opera Posthuma and the extension of his arguments against Spinozism to discredit Cartesian philosophy in general, and, finally, Leibniz’s retrospective evaluation of Spinoza’s thought in the Theodicy.

Between Giuseppe Peano and Camillo Berneri, a foremost protagonist of the Italian anarchist movement, an interesting correspondence was exchanged in the years 1925-1929. Along with a presentation of the correspondence, Peano's political attitude and the role of his international language projects in early 20th century Italian left are discussed.

The paper discusses problems related to historical change in the field of technology applied to the preservation and communication of knowledge. Debates of the years 1990s about the possible decadence of (printed) books in favour of other technologies, are evaluated with the help of a historical analogy. The art of memory was a widespread non-material technique for managing information in a world of prevalent oral communication, which was set aside by the new technologies of printed communication. In the first part, (...) the Author discusses the final phase in the history of the art of memory, sketching Lambert Schenckel’s biography as a good example of utmost individual success in the teaching of the art. Schenckel’s time sees the maximum demand for teaching in the art of memory; nevertheless those are the years when the printed book has already completely won its battle. The second part regards the possibility of a survival of the book as a technological model (i.e. as a model to build applications in new technologies for knowledge communication), notwithstanding the technologies involved in its production, just as the art of memory has been recently used as a model for constructing hypermedia, and just as the book itself survived technological revolutions in past ages. The issue is discussed carefully avoiding to engage in prophecy. (shrink)
