This chapter begins with a discussion of humanist criticisms of scholastic logic. It then discusses the evolution of the scholastic tradition and the influence of Renaissance Aristotelianism, Descartes and his influence, the Port-Royal Logic, the emergence of a logic of cognitive faculties, logic and mathematics in the late 17th century, Gottfried Wilhelm Leibniz's role in the history of formal logic, and Kant's influence on logic.

Dieser Aufsatz zeigt die Möglichkeiten auf, aus den von Leibniz im April 1679 geschriebenen logischen Abhandlungen ein numerisches Modell für die durch Widerspruchsfreiheit bestimmten Modalbegriffe zu lesen. Dazu wird als erstes die Definition der Modalisatoren durch die Widerspruchsfreiheit betrachtet und die Probleme‚ die das Leibniz'sche ‘continere’ oder ‘implicare contradictionem’ auslöst. Danach werden die in den Schriften von 1679 entwickelten numerischen Modelle untersucht‚ besonders dasjenige‚ das sich auf den Mechanismus des charakteristischen Zahlenpaares stützt. Dieses Modell wird für den Aufbau formaler Definitionen (...) von Möglichkeit‚ Unmöglichkeit‚ Kompatibilität und Inkompatibilität benutzt. Schließlich werden kurz einige spezifische Probleme angeführt‚ die die vorgeschlagene Interpretation offenläßt: die Darstellung der einfachen Begriffe innerhalb des numerischen Kalküls und die Beziehung zwischen den Wortpaaren Kompatibilität-Inkompatibilität und Kompossibilität-Inkompossibilität. Was diese letzteren betrifft‚ wird die Bedeutung betont‚ die eine diachronische Betrachtung der Leibnizschen Lehre für ein besseres Verständnis der theoretischen Zusammenhänge hat‚ in denen diese Bezeichnungen auftreten.

Premessa Questo intervento si propone di presentare, in maniera sintetica ma—speriamo — ragionevolmente completa, un’idea in fondo abbastanza semplice: utilizzare alcuni strumenti di lavoro collaborativo in rete per la redazione di bozze o progetti di testi normativi (e in particolare di progetti di legge). Le potenzialità degli strumenti di rete nel favorire non solo una maggiore trasparenza nelle varie fasi di elaborazione dei testi normativi e una loro migliore reperibilità e accessibilità...

The Wealth of Ideas, first published in 2005, traces the history of economic thought, from its prehistory to the present day. In this eloquently written, scientifically rigorous and well documented book, chapters on William Petty, Adam Smith, David Ricardo, Karl Marx, William Stanley Jevons, Carl Menger, Léon Walras, Alfred Marshall, John Maynard Keynes, Joseph Schumpeter and Piero Sraffa alternate with chapters on other important figures and on debates of the period. Economic thought is seen as developing between two opposite poles: (...) a subjective one, based on the ideas of scarcity and utility, and an objective one based on the notions of physical costs and surplus. Professor Roncaglia focuses on the different views of the economy and society and on their evolution over time and critically evaluates the foundations of the scarcity-utility approach in comparison with the Classical/Keynesian approach.

It is now generally accepted that the motor system is not purely dedicated to the control of behavior, but also has cognitive functions. Mirror neurons have provided a new perspective on how sensory information regarding others’ actions and gestures is coupled with the internal cortical motor representation of them. This coupling allows an individual to enrich his interpretation of the social world through the activation of his own motor representations. Such mechanisms have been highly preserved in evolution as they are (...) present in humans, apes and monkeys. Recent neuroanatomical data showed that there are two different connectivity patterns in mirror neuron networks in the macaque: one is concerned with sensorimotor transformation in relation to reaching and hand grasping within the traditional parietal-premotor circuits; the second one is linked to the mouth/face motor control and the new data show that it is connected with limbic structures. The mouth mirror sector seems to be wired not only for ingestive behaviors but also for orofacial communicative gestures and vocalizations. Notably, the hand and mouth mirror networks partially overlap, suggesting the importance of hand-mouth synergies not only for sensorimotor transformation, but also for communicative purposes in order to better convey and control social signals.

In The Cultural Roots of Strategic Intelligence, Gino LaPaglia argues that Strategic Intelligence is a core dynamic of human rationality and that it has always been foundational for creating meaning in society. For thousands of years the identity of the heroic strategist has provided hope for human life lived in extremis.

En contra de la interpretación de Anselm Jappe del fetichismo de la mercancía como contradicción principal del capitalismo, sostengo que su obra adolece de un sobredimensionamiento del fetichismo que resulta determinista y reduccionista, y que comprende la contradicción en la obra de Marx de un modo simplista. Ofrezco, en cambio, una interpretación del fetichismo que parte de la noción de que la mercancía es una cristalización de las relaciones sociales de las sociedades capitalistas junto con una defensa de la contradicción (...) como motor dinámico del capitalismo antes que como aspecto paradójico del mismo.

A comprehensive interpretation of the "Scienza Nuova" and of the ways in which Vico managed to present his essentially naturalistic philosophy in a form acceptable within the ecclesiastical climate of 18th century Italy.

Archibald Pitcairne’s medical writings are inspired by Newton’s Principia mathematica, as the Scottish physician assumed Newtonian physics as a model for scientific inquiry that should be applied to other branches of natural philosophy, including physiology and pathology. The ideal of a comprehensive mathematical science was very appealing to late seventeenth-century intellectuals, including physicians. This essay focuses on how Pitcairne tried to implement these ideas. In particular, I argue that Pitcairne’s medical thinking is based on three philosophical assumptions: first, a methodological (...) assumption, for which medical knowledge should be sought in the form of a deductive system; second, an epistemological assumption, that is, that our knowledge of physiological processes is sound only when we reduce them to a set of mathematical laws; and, third, an ontological assumption that identifies blood as the substance on which animal life most directly depends. I also suggest that such ideas should be studied against the backdrop of Pitcairne’s general mindset, including his personal sympathy for political conservativism. I further argue that his insistence on the reduction of natural processes to mathematical relations and his search for the universal order of nature also connect to his religious and political ideals.

The contributions to this book touch the different aspects of Popper's philosophy of science.

Describing the will and the extent of its causal power over human actions, Joseph Priestley famously compared the mind to a stone, as both are subject to deterministic laws: “Though an inclination...
