In the first chapter of the Origin of species and in two chapters of the Variation of animals and plants under domestication, Darwin discusses the origin of domestic pigeons, claiming that all the known breeds were produced from a single species: Columba livia, the rock pigeon. The detailed defense of this point is of high relevance in Darwin’s argumentation strategy, since the differences between the several domestic breeds is so large that, if they were found in the wild, they could (...) be classified as different species or genera. If man was able to produce such large differences, it becomes plausible that nature can produce even larger differences, and therefore the process of natural selection becomes acceptable. Darwin emphasizes the enormous differences between the several domestic breeds (that may have dissimilar cranial structures and a varying number of vertebrae), and at the same time he attempts to show that there are connections and transitions between the extreme types, arguing for their common origin. One of the several interesting parts of his argument is an experiment of crossing between widely different breeds, which led him to obtain pigeons similar to the wild species. The detailed analysis of Darwin’s study of pigeons shows the extreme care he took in his attempt to provide strong arguments for his theory. RESUMO: No primeiro capítulo do Origin of species, e em dois capítulos do Variation of animals and plants under domestication, Darwin discute a origem dos pombos domésticos, defendendo que todas as raças conhecidas provêm de uma única espécie: Columba livia, o pombo de rocha. A defesa detalhada desse ponto é de grande importância na estratégia argumentativa de Darwin, pois as diferenças entre as várias raças de pombos são tão grandes que, se fossem encontradas em estado selvagem, poderiam ser classificadas como espécies ou gêneros diferentes. Se o homem foi capaz de produzir mudanças tão grandes como essas, torna-se plausível que a natureza possa produzir diferenças ainda maiores, e assim o processo de seleção natural se torna aceitável. Darwin enfatiza as grandes diferenças entre as raças de pombos (que chegam a possuir, por exemplo, diferentes estruturas cranianas e diferentes números de vértebras), e ao mesmo tempo procura mostrar a existência de nuances e transições entre os tipos extremos, para defender a origem comum. Um dos aspectos interessantes de sua argumentação é um experimento de cruzamento entre raças bem diferentes, através da qual obtém pombos semelhantes à espécie selvagem. A análise detalhada desse estudo de Darwin mostra o extremo cuidado que ele tomava para tentar proporcionar fortes argumentos a favor de sua teoria. (shrink)

Among the studies on the history of philosophy recently published in Italy, one that may be of some interest to the English reader is by D R . Abbagnano , a young pupil of Aliotta , and is devoted to the new English idealism. 1 Truthfully speaking, the term ‘ new ’ is inappropriate, or partly so, because Abbagnano dedicates the greater part of his study to what we might call the ‘ old ’ idealism in England, represented by Stirling, (...) the two Cairds, Wallace, Green, and Bradley. However, he does also pass in review the more recent doctrines, particularly those of J. H. Muirhead, G. H. Howison, D. G. Richtie, J. E. Creighton, J. B. Baillie, J. S. Mackenzie, H. Jones, W. E. Hocking, A. S. Pringle Pattison, and G. P. Adams. Abbagnano regards as a distinctive trait of English idealism inspired by Hegel as opposed to Hegel himself, this, that “for Hegel the absolute is essentially process, change and becoming; it is thought which differentiates itself and becomes articulate in a life of its own, in the threefold rhythm of thesis, antithesis, and synthesis, in which each moment passes into the next. For Green, Bradley, and Royce, the absolute is on the other hand immutability, completeness, static perfection, in which each process and becoming is overcome and resolved.” At any rate, Abbagnano is equally unsympathetic towards Hegel and towards his followers, against whom he opposes, not without scholastic ingenuity, his own irrationalistic views, set out in another book whose contents are sufficiently expressed in the title. 1.

In 1920 Bignone published an Italian translation of the writings and fragments of Epicurus in Laterza's library of Ancient and Mediaeval Philosophers which in many respects added to and improved upon Usener's classic collection, of Epicurea. He has since then zealously prosecuted these studies, and arrived at some very interesting conclusions which he has given out in two volumes published lately.1 His starting-point is the observation that the writings of Epicurus often have a polemical tone, and not only rebut the (...) accusations of adversaries who misinterpret the new doctrine, but are often directed also against those preceding philosophers who denied to pleasure a stable and certain nature on which a system of ethics could be based. Bignone has set himself the task of particularizing these anonymous predecessors, and thereby bringing the Epicurean polemic into more striking relief. I t was easy and safe to start from the standpoint that Epicurus in his rehabilitation of pleasure had to oppose Plato and the Platonists, but at what Platonists in particular did he take aim? In answering this question Bignone has been able to make use of recent Aristotelian studies, especially those of Jaeger, which have thrown much light on the first phase of the Stagirite's philosophy, of a purely Platonic inspiration. As is well known, some exoteric dialogues belong to this phase, such as the Eudemos, the Protrepticon, and On Philosophy, which have to a large extent disappeared, though it has been found possible to reconstruct a few scattered fragments of them. The great scholastic works which reveal the full independence and maturity of Aristotle's genius have eclipsed them in the memory of posterity. But originally there were only these dialogues, the only ones published, to make Aristotle's thought known to the public outside the peripatetic school. The scholastic writings on the other hand remained unknown until the time of Sulla. What wonder, then, if Epicurus, in combating Platonism, had in mind these dialogues, which give out the fundamental conceptions of Platonism in a more decisive and dogmatic form than that of the Platonic dialogues?

Contacts between Italian and English thought of late years have been both frequent and effective.

In his celebrated historic-epistemological work Identité et réalité, Émile Meyerson claimed that the scientific conservation principles were first suggested and accepted for philosophical reasons, and only afterwards were submitted to experimental tests. One of the instances he discussed in his book is the principle of mass conservation in chemical reactions. Meyerson pointed out that several authors, from Antiquity to Kant, accepted the idea of quantitative conservation of matter; and Lavoisier himself was strongly influenced by a priori ideas, using this principle (...) instead of attempting to test it. This paper will review Meyerson’s claim and historic evidence, focusing especially the late nineteenth and early twentieth century, when the principle of mass conservation was tested in highly accurate experiments. Instead of confirming the principle, some of those experiments led to the detection of anomalies. Hans Landolt, for instance, noticed that there were some small violations of the principle. He observed mass variations of about 10−6 in chemical reactions produced in hermetically sealed glass tubes. Since Landolt was a famous chemist, his results produced a strong response. Several researchers repeated his experiments, with different results. Landolt himself improved his experiments, with a balance that could detect mass changes of 10−7. After changes of the experimental procedure, the chemical reactions did not show significant mass changes. There was not, however, any “crucial experiment” “proving” that mass was conserved. The observed anomalies were set aside mainly by theoretical reasons, after the discovery of radioactivity and the development of the theory of relativity. (shrink)

Originally published in 1921, this volume represents De Ruggiero's first appearance in English, being the first time his philosophical works were translated. Modern Philosophy presents a positive philosophical position of great interest, avowedly in continuation of Croce and in close agreement with Gentile, which sums up the progress of Italian idealism down to the writing of this book. It is a remarkable piece of historical work, focusing on the development of European philosophy in the second half of the nineteenth (...) century and the beginning of the twentieth, and was the first volume to comprehensively handle this time period.

F. Enriques and G. de Santillana have begun in collaboration the composition of a general history of scientific thought. The first volume of this work, which has been recently published, is concerned with the science of antiquity,1 and to a large extent covers the same ground as the history of ancient philosophy, as the frontiers of philosophy and natural science, at any rate until the time of Aristotle, were not yet clearly differentiated. But the two historians are interested in bringing (...) into prominence a great many problems and personalities that the history of philosophy generally leaves on one side, although they help to complete and vivify the picture of the mentality of the ancients. Mathematics, medicine, geography, astronomy, applied mechanics, and physics, in short all the particular scientific studies that were just beginning to detach themselves from the parent trunk of general philosophy are studied by the authors in their individual developments and through the personalities of their cultivators. The explanations are clear and simple and can be followed even by readers unversed in science; the information is at first hand and is supplemented by a careful discussion of sources. The scientific questions are not isolated from the historical setting of the civilization of antiquity, but are shown in relation to matters of philosophy, religion, art, and moral and political life. The bibliography, intended for the more purely scientific and technical departments of philosophy, forms a very useful and timely completion of the bibliography of philosophic thought in general. (shrink)

Of late years, even in Italy, no really new personalities or original orientations of thought have made their appearance in philosophy. The best that has been done in our studies consists in ample work consolidating the mental positions already gained during the prewar period, and in slow but unceasing efforts of philosophic thought to permeate the other strata of our culture. It is not paradoxical to affirm that to-day the best fruits of the renewed philosophic education are to be gathered (...) not in books of philosophy, but in books of literary and artistic criticism, of history, and of political and moral science. All this is not merely fortuitous, but proceeds directly and consciously from the trend of the new Italian philosophic thought, which shrinks from isolating itself in an intellectual and fictitious superworld, preferring on the contrary to be a living methodology of the sciences, and to give to its universals the relief and, I might almost say, the savour, of particular things.

In a posthumous book by F. Meli 1 there are joined two interesting studies in the history of philosophy. The first discusses the religious and political doctrines of Fausto Socino and their developments in the thought of the seventeenth century, and the second the rationalistic mentality of Spinoza. The two themes are essentially related, for in the religious rationalism of Socino the author recognizes one of the currents of thought that were to meet later in Spinoza’s philosophy. The first essay (...) has the merit of greater novelty, because Socinian studies have been neglected up to the present and only touched on indirectly, in their repercussions rather than in their origins. For Meli the historical importance of Fausto Socino lies in the fact that he draws from the religious experience of the Reformation a new conception of religion, clearly affirming the principle that Holy Scripture does not aim at conveying abstract knowledge, a scientific doctrine, but on the contrary, as Galileo confirmed, it aims at increasing in us justice, charity, and the moral sense.

A re-publication of the whole of the work of Marsilio Ficino, being an impossibility, Kristeller1has presented students with a monumentalSupplementum Ficinianum, in which he brings together everything that was not included in the Basle edition, which he takes for his basis, everything, that is to say, that he has been able to trace in the course of a very thorough search made in numerous Italian and foreign libraries. In a learned introduction there are prefixed to the edition three indexes, of (...) the codices, editions, and works of Ficino, and with each work is given a concise account of its origin, purpose, and fortune in the world. There follows the collection of Ficino's writings, some unpublished, and some having already been published sporadically, but omitted from the Basle edition. The final items are two indexes of proper names quoted in the Basle edition and in theSupplementumrespectively. (shrink)

Of late yeaxs Benedetto Croce's interpretation of the philosophy of G. B. Vico has been exposed to continual criticism from Catholic writers anxious to claim for themselves the figure of the great eighteenth-century thinker, wrested from them by Croce for inclusion in a setting of secular and immanentistic philosophy. The Catholic polemic was founded partly on a false supposition: it derived from the idea that Croce meant to deny entirely Vico's Catholicism. Instead, Croce made a distinction between Vico the man (...) and Vico the philosopher. While he recognized that the man cherished Catholic sentiments and beliefs, he denied that the philosopher could reenter the circle of dogmatic and confessional philosophy. To confirm the accuracy of his interpretation, Croce has now republished an interesting monograph by an eighteenth-century Catholic writer, a little later than Vico, G. F. Finetti,1 who subjects the doctrine of Vico to a lively criticism. The motive of this exhumation is plain: “The protest of eighteenth-century Catholic criticism against the doctrines of Vico, or rather, against the doctrines of an author well known to be a blameless observant throughout his life, is of considerable importance because it is the first real acknowledgment of the revolutionary spirit, the anti-Catholic and generally anti-religious spirit, which informed his doctrines.”.

There has lately been published a posthumous work on “pure realism” by an Italian philosopher who died a little while ago at an early age. He had been working on the book for some time with great concentration of energy, but did not live to finish it. In the form in which it has been edited for publication some parts of it have been developed almost to completion, while others are mere sketches and notes—though not wanting in interest, for they (...) reveal the author's method of working, and expose doubts and difficulties in the immediate form in which they presented themselves to his mind and found the way to a solution. The most complete section is one dealing with the critique of idealism, a critique which, while it is not devoid of ingenuity, is in the main stringent and vigorous, and deserves particularly the consideration of idealists. The principal thesis is that there are two possible solutions of the problem of consciousness. It admits the possibility either that consciousness itself creates its own world, endowing it, thanks to the action of the mind on its own images, with those physical attributes that make it appear external to the subject or independent of the activity by virtue of which it is formed ; or that consciousness is the immediate revelation of the world itself to itself, a revelation that can only consist in a unique act whereby the world establishes itself as identical with itself and as different from itself, as internal and external knowing and known, spirit and nature. At the basis of idealism, according to Ranzoli, is the implied presupposition that like is conscious only of like, and at the basis of realism is the Anaxagorean presupposition that opposite is conscious of opposite.

Shaftesbury is one of those philosophers who are usually placed more or less in the margin of the history of thought because an insufficient idea of system and a certain looseness of conception make it difficult to grasp their ideas and to classify them. Yet when you are able to break down or to dismiss the mental figures in which you have been accustomed to consider the historical succession of doctrines and are prepared to revive their words with an open (...) mind, not only do they give you in their originality more than you had hoped, but also they help to render your representation of intellectual life as a whole more complex and more harmonious in its development. Bandini,1an Italian scholar, in making a zealous study of Shaftesbury, has succeeded in drawing out his rich personality, and at the same time in explaining the importance of his contribution to theperennis philosophia. We could hardly succeed in understanding the modern English mind in its genesis if we concentrated our attention exclusively on those empiristic currents which, although they preponderate in Anglo-Saxon speculation, do not contain all its originality. There is a deep fount of romance in the spirit of this people which wells up from time to time, and the drier and harder the surface earth the more strongly it gushes forth. Shaftesbury is just such a fount, isolated and inexplicable to all outward appearances, but far otherwise for anyone who knows how to penetrate below the surface. In his essay Bandini, while emphasizing the contrast between the philosophy of moral enthusiasm and feeling and the contemporaneous doctrines of Hobbes and Locke, examines with equal penetration the way in which the former becomes reattached to English speculative tradition and by what means it contributes in its turn to furnishing new trends in philosophy.

After an interruption of seven years I take up once again my surveys of Italian philosophy. Many things have happened in the interval, but it is perhaps too soon for them to be susceptible of calm philosophical reflection. The problems that most interest the cultured public to-day are those of existentialism, of historicism and its limits, of German romanticism, and, more generally, of Germanic culture in relation to new spiritual orientations. The interest in existentialism is due, at least in part, (...) to the fact that it is the philosophy in fashion. But there is in it nevertheless a depth of seriousness that is not overlooked. The tragedies of recent years have placed in the foreground the problems of immediate existence, of human personality and its place in the world, which the preceding idealistic philosophy had too easily absorbed in an impersonal and trans-subjective view of the spirit and its universal values. And, as has often happened in the course of history, there has resulted a reaction of individuality, in its most irrational and vital expressions, against the pretensions of reason to dominate it from above, and imprison it in the net of its concepts. But if, in this regard, existentialism represents a just demand, which can exercise a beneficial influence on philosophical thought, yet to many its claim to represent a new era in philosophy seems excessive. Its value is only that of an episode. Hence some interpreters of contemporary thought have been drawn to limit the importance of the new movement. (shrink)

BenedettoCroce'sbook on history1is the ideal continuation of his earlier book published over a score of years ago on “La Teoria e Storia della storiografia” forming the final part of the “Filosofia dello spirito.” During this long period Croce has had the opportunity to enrich and extend his historiographical experiences with a series of volumes, of which those on the History of Naples, the History of Italy, and the History of Europe in the Nineteenth Century are the most important and have (...) had the widest repercussions. In all this range of experience his fundamental theses on the character and value of history have not been substantially altered. They have actually developed in breadth and depth, so that in the present volume we find them with their characteristic lineaments, old and new together, rendered fuller and more vivid by the rich lymph of the concrete problems of historical life by which they are nourished. In the meantime a series of violent and tumultuous changes, provoking vehement opposing mental reactions, has brought into discussion grave doubts, raised on certain points which first appeared firmly established in the historical view of the world. The antithesis has moved Croce to reaffirm his thought with renewed polemic ardour, thereby throwing it into stronger relief, and giving it a greater sense of reality. (shrink)

Although the few references to the term, Nietzsche's notion of perspectivism is an important assumption of his philosophical reflection. It is a notion, as it will be tried to demonstrate, significant for the understanding of many theoretical positions of the author concerning science and knowledge and decisively for the interpretation of both notions as interpretative perspectives The following argument aims to analyze the influences and assumptions of this notion, highlighting its Kantian (Neokantian), Schopenhaurian background, but also considering influences outside of (...) philosophy, such as Ruggero Boscovich's theoretical physics, which plays a decisive role in the formulation of the notions of perspectivism and perspectivist interpretation in Nietzsche's philosophy.

O objetivo deste artigo é investigar quais são as bases ontológicas da ética do futuro, tendo como leitmotiv o conceito de reciprocidade ou, sendo mais preciso, justamente a sua prescindibilidade no âmbito ético, a qual repercute como necessidade ontológica de fundamentação. Partiremos de uma análise do próprio conceito de “ética do futuro” para, explicitar, na sequência, por que, com Jonas, o futuro se torna objeto ético e como ele exige a prescindibilidade da reciprocidade. A partir daí, pretendemos mostrar que a (...) fundamentação ontológica da ética é o caminho de solução para o problema da ausência de reciprocidade e de que modo ela se constitui como crítica àquilo que Jonas chama de dois dogmas da filosofia: “nenhuma verdade metafísica” e “nenhum caminho do é para o deve” (PR, p. 95). Por isso, finalmente, tentaremos mostrar que é contra esses dogmas que se ergue a proposta jonasiana, fundamentada numa metafísica racional que nada mais é do que uma ontologia biológica. (shrink)

Este trabajo analiza las diferencias entre las teorías de Lorentz y Poincaré (quienes aceptaban el éter) y de Einstein, cuestionando las explicaciones comunes de los motivos por los cuales la teoría de la relatividad es preferible a la anterior. La principal diferencia entre los puntos de vista de Einstein y de Lorentz y Poincaré era de naturaleza epistemológica y no teórica. Cada uno de los enfoques tenía aspectos epistémicos positivos, pero de la misma manera les hacía falta a los dos (...) puntos de vista determinados aspectos que estaban presentes en la otra propuesta. Por lo tanto, una de ellas no era superior a la otra. De ese modo, no había argumentos conclusivos que permitieron elegir una de ellas y rechazar a la otra. (shrink)
