The content of Boscovich’s Theoria philosophiae naturalis was well-known to his contemporaries, but both scientists and philosophers chiefly discussed it during the 19th century. The observations that Boscovich presented in this text, and that he himself defined as “philosophicas metitationes”, soon showed their being a good programme for the forthcoming atomic physics, and contributed to get rid of the mechanistic paradigm in science. In this paper I’ll go back to some meaningful moments of the history of Boscovich’s (...) reception in the era of contemporary philosophy, by referring to what authors such as Popper, Cassirer, Nietzsche and Fechner wrote about him. These thinkers, indeed, particularly stressed the importance of the Theoria in the history of Western thought, and showed that it can easily be evaluated beyond the plane of a pure scientific investigation.

Leibniz’s main thesis regarding the nature of space is that space is relational. This means that space is not an independent object or existent in itself, but rather a set of relations between objects existing at the same time. The reality of space, therefore, is derived from objects and their relations. For Leibniz and his successors, this view of space was intimately connected with the understanding of the composite nature of material objects. The nature of the relation between space and (...) matter was crucial to the conceptualization of both space and matter. In this paper, I discuss Leibniz’s account of relational space and examine its novel elaborations by two of his successors, namely, the young Immanuel Kant and the Croat natural philosopher Roger Boscovich. Kant’s and Boscovich’s studies of Leibniz’s account lead them to original versions of the relational view of space. Thus, Leibniz’s relational space proved to be a philosophically fruitful notion, as it yielded bold and intriguing attempts to decipher the nature of space and was a key part in innovative scientific ideas.

L’analisi dei principali temi della filosofia di Nietzsche conduce all’individuazione della nozione di forza come elemento centrale delle sue riflessioni. Egli la incorpora ed utilizza filosoficamente, in periodi diversi, per la definizione di teorie centrali quali l’eterno ritorno, la volontà di potenza e il prospettivismo conoscitivo. L’assimilazione di questa nozione – come è stato osservato in passato – può essere riportata alla sua lettura nel 1873 della Theoria philosophiae naturalis del matematico Ruggero Boscovich. Attraverso una dettagliata analisi del materiale (...) postumo oltre che del contesto delle discussioni scientifiche dell’epoca, questo studio si propone di chiarire nella maniera più esaustiva fino a che punto il sistema di Boscovich e, più in generale, la visione dinamica del mondo in esso delineata abbiano influito sul pensiero nietzscheano, con la precisa finalità di restituire nella sua complessità il rapporto di Nietzsche con questa figura.

Boscovich' theory of natural philosophy, published in 1758, made a great influence on his peers and had plenty of followers in centuries to come. It contributed to the discovery of atomic structure and inspired many scientists to work on further advancements of modern material structure comprehensions. In 1993, the physicist Leon Ledermann, a Nobel Prize laureate, wrote that 'Boscovich's philosophy is a key for the entire modern physics'. German philosopher Nietzsche regarded Boscovich's theory 'the greatest triumph over (...) the senses that has yet been achieved on earth'. Frenchman Herismann believed that 'the entire Boscovich's philosophy will become a philosophy of the 21st century'. This article includes a presentation of Boscovich's life and activities, description of his philosophy as well as its contributions to modern science and philosophy. (shrink)

It is often assumed that the suppression of the Jesuits in 1773 meant an abrupt dissipation of Jesuit intellectual culture and science. Recent interest in this period, however, indicates that Jesuit theologians, philosophers, and scientists constituted a heterogenous group and that the suppression affected them in various ways. This paper builds on this research and deals with the following question. What can a micro-historical approach, focusing on individuals rather than on general cultural trends, reveal about the effects of the suppression? (...) The paper focuses on five Jesuit scientists who lived through the suppression and who represent different lines, or forms, of philosophical and empirical inquiry. After this first section, the argument shifts to more general considerations, referring to some counterfactual situations, in view of evaluating the cultural and scientific cost of the suppression.

[English in PhilArchive, unpublished]. Ruđer Bošković's (Rogerius Joseph Boscovich, 1711-1787) induction is described as a reasoning procedure that combines abductive, generalizing and deductive forms of inference. According to Bošković, the application of inductive reasoning extends beyond natural science. Bošković's critique of the use of the principle of sufficient reason is discussed, and constructive rules of Bošković's inductive logic are proposed from the standpoint of contemporary justification logic. To that end, justification logic could be extended with Bošković's typology of reasons. (...) Hunter's result (1965) is conceived as a confirmation that the inference from the constructive defectus rationis is a necessary component of Bošković's induction. - English version in _PhilArchive_.

Joseph Priestley was a man of many and varied intellectual interests. This thesis surveys his philosophical thought, with a central focus on his philosophical theology. The subject can be divided into two parts, natural theology and moral theology. Priestley's natural theology is a perhaps unique attempt to combine and harmonize materialism, determinism and theism, under the auspices of Newtonian methodology. His materialism is based on three arguments: that interaction between matter and spirit is impossible; that a dynamic theory of matter (...) breaks down the active/passive dichotomy assumed by many dualists; and that Newton's "Rules of Reasoning in Philosophy" require the rejection of the "hypothesis" of the soul. His determinism arises from his theory of causation. He attempts to show that the only acceptable account of causation is one in which every cause is invariably followed by the same effect, and that libertarianism violates this central assumption of scientific thought. His theism rests on the Argument from Design. He defends the Argument by trying to show that none of the alternatives to Design advanced in Hume's Dialogues concerning Natural Religion constitute a plausible scientific hypothesis. His critics accused his synthesis of materialism, determinism and theism of leading to atheism or pantheism. His defence against these charges is that his system is essentially theistic, and that its ontology is determined by the Argument from Design. Priestley's moral theology is also in part a response to Hume's Dialogues. He offers a number of replies to the "problem of evil". Evil and adversity heighten our appreciation of good; they are a consequence of the finitude of the creation; they follow from the desirability of having a world governed by general laws; and they make possible the achievement of moral character. Character-formation is his main defence, and his methodology requires him to show that adversity leads more often than not to positive results. This requirement is embodied in his progressivist philosophy of history. History, he holds, exhibits temporal purpose and Design, just as nature exhibits atemporal purpose and Design. Priestley's political thought can be seen as arising from his moral theology, mediated by the notions of "luxury", which he regards as morally harmless, and "idleness", which is the main source of moral evil. His combination of liberalism and radicalism is examined both for internal consistency and as a response to the events of his day, ending with the French Revolution. Priestley is interesting partly for his unorthodoxy, partly for the inter-connectedness of his diverse concerns, and partly because he debated with distinguished contemporaries. Throughout the thesis his views are juxtaposed with those of Hume, Reid, Price, Boscovich, Burke and a number of other thinkers. (shrink)

Marea varietate de materie cu care ne confruntăm în experiența de zi cu zi este formată din atomi. Existența unor astfel de particule a fost propusă pentru prima dată de către filosofii greci, precum Democrit, Leucip, și epicurienii, dar fără niciun argument real, astfel încât conceptul a dispărut. Aristotel argumenta împotriva indivizibililor lui Democrit (care diferă considerabil de utilizarea istorică și modernă a termenului "atom"). Conceptul atomic a fost reînviat de Rudjer Boscovich în secolul XVIII, și apoi aplicat în (...) chimie de John Dalton. Atomul este cel mai mic constitutiv ireductibil al unui sistem chimic. Cuvântul este derivat din limba greacă, atomos, indivizibil, format din particula a-, nu, și tomos, divizare. Acesta reprezintă de obicei atomi chimici, componentele de bază ale moleculelor și materia obișnuită. Acești atomi nu sunt divizibili prin reacții chimice, dar sunt acum cunoscuți a fi compuși din particule subatomice chiar mai mici. Dimensiunile acestor atomi sunt în general în intervalul de la 22 până la 100 pm. (shrink)
