We give a geometric realization of space-time spinors and associated representations, using the Jordan triple structure associated with the Cartan factors of type 4, the so-called spin factors. We construct certain representations of the Lorentz group, which at the same time realize bosonic spin-1 and fermionic spin- $${\raise0.7ex\hbox{$1$} \!\mathord{\left/ {\vphantom {1 2}}\right.\kern-0em}\!\lower0.7ex\hbox{$2$}}$$ wave equations of relativistic field theory, showing some unexpected relations between various low-dimensional Lorentz representations. We include a geometrically and physically motivated introduction to Jordan triples and spin factors.

The classics appear conspicuously in the pamphlet wars of the American Revolution, though in the opinion of Bernard Bailyn , their presence is “window-dressing” and their influence “superficial.” They are “ everywhere illustrative, not determinative, of thought” . Up the scale in influence comes Enlightenment rationalism, also “superficial” but only “at times”—that removes the foreigners, ancient and modern. Then, further up the scale are English common-law writers, “powerfully influential” though still insufficiently “determinative”; above them, a “major source,” New England (...) Puritan thought and culture; and finally, at the top, seventeenth-century British “heroes of liberty” and the “early eighteenth-century transmitters of this tradition,” e.g. Commonwealth men, Bishop Hoadly. Who would have thought that the bishop of Winchester weighed in the balance more heavily than Plato and Aristotle? Only once in passing does Bailyn even mention Machiavelli, to whom J. G. A. Pocock, Quentin Skinner, and Harvey C. Mansfield would grant large prominence in the development of Revolutionary thought. (shrink)

Conscious experience is one of the most difficult and thorny problems in psychological science. Its study has been neglected for many years, either because it was thought to be too difficult, or because the relevant evidence was thought to be poor. Bernard Baars suggests a way to specify empirical constraints on a theory of consciousness by contrasting well-established conscious phenomena - such as stimulus representations known to be attended, perceptual, and informative - with closely comparable unconscious ones - such (...) as stimulus representations known to be preperceptual, unattended, or habituated. Adducing data to show that consciousness is associated with a kind of global workplace in the nervous system, and that several brain structures are known to behave in accordance with his theory, Baars helps to clarify many difficult problems.

Manipulationism holds that information about the results of interventions is of utmost importance for scientific practices such as causal assessment or explanation. Specifically, manipulation provides information about the stability, or invariance, of the relationship between X and Y: were we to wiggle the cause X, the effect Y would accordingly wiggle and, additionally, the relation between the two will not be disrupted. This sort of relationship between variables are called 'invariant empirical generalisations'. The paper focuses on questions about causal assessment (...) and analyses the status of manipulation. It is argued that manipulationism is trapped in a dilemma. If manipulationism is read as providing a conceptual analysis of causation, then it fails to provide a story about the methods for causal assessment. If, instead, manipulationism is read as providing a method for causal assessment, then it is at an impasse concerning causal assessment in areas where manipulations are not performed. Empirical generalisations are then reassessed, in such a way that manipulation is not taken as methodologically fundamental. The paper concludes that manipulation is the appropriate tool for some scientific contexts, but not for all. (shrink)

In Morality Bernard Williams confronts the problems of writing moral philosophy, and offers a stimulating alternative to more systematic accounts which seem nevertheless to have left all the important issues somewhere off the page.

Descartes has often been called the 'father of modern philosophy'. His attempts to find foundations for knowledge, and to reconcile the existence of the soul with the emerging science of his time, are among the most influential and widely studied in the history of philosophy. This is a classic and challenging introduction to Descartes by one of the most distinguished modern philosophers. Bernard Williams not only analyzes Descartes' project of founding knowledge on certainty, but uncovers the philosophical motives for (...) his search. With acute insight, he demonstrates how Descartes' _Meditations _are not merely a description but the very enactment of philosophical thought and discovery. Williams covers all of the key areas of Descartes' thought, including God, the will, the possibility of knowledge, and the mind and its place in nature. He also makes profound contributions to the theory of knowledge, metaphysics and philosophy generally. With a new foreword by John Cottingham. (shrink)

Die "Paradoxien des Unendlichen" sind ein Klassiker der Philosophie der Mathematik und zugleich eine gute Einführung in das Denken des "Urgroßvaters" der analytischen Philosophie. Das Unendliche - seit jeher ein Faszinosum für die philosophische Reflexion - wurde in der Zeit nach der Grundlegung der Analysis durch Leibniz und Newton in der Mathematik zunächst als Problem betrachtet, das sich nicht vollkommen widerspruchsfrei behandeln lässt. Bernard Bolzano, der heute als "Urgroßvater der analytischen Philosophie" (Michael Dummett) gilt, zeigt in diesem klassisch gewordenen (...) Text jedoch, dass es beim Nachdenken über das Unendliche, sofern man begrifflich differenziert argumentiert und klare Definitionen zugrunde legt, keine echten Widersprüche gibt und sich die "Paradoxien des Unendlichen" auflösen lassen. Bolzano setzt sich zunächst mit den Unendlichkeitsbegriffen der Mathematik und der (idealistisch geprägten) Philosophie seiner Zeit auseinander, bevor er sich Schritt für Schritt die analytischen Grundlagen einer konsistenten Theorie des Unendlichen erarbeitet. Bereits einige Jahrzehnte vor Georg Cantors bis heute maßgeblicher mathematischer Unendlichkeitsdefinition gelingt Bolzano mit diesem Werk, dessen logische Klarheit und dessen Grad an philosophischer Durchdachtheit bis heute Beispielcharakter haben, die Rehabilitation des Unendlichen für die Philosophie der Mathematik. Die "Paradoxien des Unendlichen" wurden zuerst 1851 aus dem Nachlass herausgegeben. Diese Neuausgabe beruht auf dem der Erstausgabe zugrundeliegenden Manuskript. (shrink)

Questo libro suggerisce d'inserire il nome di Arthur Schopenhauer nella tradizione della filosofia come stile di vita. Sulla scia dei pioneristici lavori di Paul Rabbow, Michel Foucault e soprattutto Pierre Hadot, si argomenta come anche nei libri di Schopenhauer questa tradizione sia viva. In particolare, è negli "Aforismi sulla saggezza della vita", contenuti nei "Parerga e paralipomena", che è possibile trovare traccia di quelle pratiche che Hadot ha proposto di chiamare esercizi spirituali. Ciò che ne emerge è un "altro" Schopenhauer. (...) Non più, non tanto, non solo il grande campione del pessimismo, il negatore della volontà di vita, il filosofo del dolore e della noia. Ma un prezioso suggeritore su come sia possibile vivere una vita se non proprio più felice, certamente il meno infelice possibile. (shrink)

C’è prima la persona o prima la società? Per non cadere in una risposta dualistica, bisogna risalire alle radici antropologiche della vita sociale, che stanno alla base delle diverse forme che essa storicamente può assumere. Questo saggio esamina il rapporto tra le tendenze socializzanti innate e le virtù relazionali, alla luce di un’antropologia integrale, nella quale la persona umana è considerata nella sua globalità somatico-psichico-spirituale. Vengono qui esaminati il tessuto di legami in cui è inserita la nostra esistenza e la (...) responsabilità che compete a ognuno nei confronti del cosiddetto capitale sociale. (shrink)

Julián Marías (1914-2005) è un pensatore ancora poco conosciuto al lettore italiano, spesso oscurato dall’ombra del suo celebre maestro, José Ortega y Gasset. Filosofo indipendente e coraggioso, offre una proposta più coerente rispetto a Ortega sul tema essenziale comune a entrambi: il poter “dare ragione” della vita evitando gli opposti scogli del razionalismo e del vitalismo. “Dare ragione” della vita significa comprenderla nella sua “condizione morale” che trova espressione nel desiderio di felicità, nell’esigenza di amore e di amicizia, nei differenti (...) vissuti di ciascuna età. Significa riconoscerne la dimensione elettiva: vivere è preferire, saper fornire ragioni per l’opzione di qualcosa rispetto a qualcos’altro. Per questo motivo, più che alla categoria del bene, l’attenzione è rivolta a quella del meglio, fondamentale per comprendere il senso pieno delle proprie scelte e dell’intera trama della propria biografia.

Causal analysis in the social sciences takes advantage of a variety of methods and of a multi-fold source of information and evidence. This pluralistic methodology and source of information raises the question of whether we should accordingly have a pluralistic metaphysics and epistemology. This paper focuses on epistemology and argues that a pluralistic methodology and evidence don’t entail a pluralistic epistemology. It will be shown that causal models employ a single rationale of testing, based on the notion of variation. Further, (...) I shall argue that this monistic epistemology is also involved in alternative philosophical theories of causation. (shrink)

Medical practitioners have always been expected to abide by certain standards of conduct and uphold certain values, more or less throughout the world. In this book, besides discussing specific ethical issues, the author ponders questions such as the right to life and the integrity of the human person. Ethics in medicine takes account of the principles that underlie the best decisions, particularly in unusual circumstances – such as a pandemic. Many of these are enshrouded in the oaths most doctors take (...) – the Hippocratic Oath is perhaps the best known, and has influenced numerous others over the centuries. However, these principles and the resulting conduct have taken different directions at various moments in history and in different parts of the globe, though always primarily oriented to the protection of human health. The author compares some interesting similarities and differences, tracing the main social, legal and religious attitudes, in what has come to be known as "medical ethics", with all its benefits to Mankind. Alongside basic human dignity, four main values have been pivotal in medical ethics: Caring for sick people, putting their well-being at the center of concern, and doing good. Not causing harm: never making a patient take risks, and never prescribing a doubtful treatment. Fairness: treating all patients in accordance with their health needs, never favoring or neglecting anyone on the basis of background, occupation, etc. Self-determination: the patient can be informed about treatments and, when possible, should approve the prescriptions. The doctor must show empathy, respect for confidentiality, and responsibility. Briefly, this overview of the medical profession’s ethics focuses on experience, principles, aims, virtues and above all the basic rules which in various places through the centuries have governed the tortuous paths of Mankind. Written by an acclaimed expert in the field, this book is of value for all those working in healthcare, and people interested in its ethics. (shrink)

This book offers an up-to-date insight into the early philosophical debate on Einsteinian relativity. The essays explore the reception and interpretation of Einstein’s ideas by some of the most important philosophical schools of the time, such as logical positivism (Reichenbach), neo-Kantianism (Cassirer, Natorp), critical realism (Sellars), and radical empiricism (Mach). The book is aimed at physicists and historians of science researching the epistemological implications of the theory of relativity, as well as to scholars in philosophy interested in understanding how leading (...) philosophical figures of the early twentieth century reacted to the relativistic revolution.

The book is devoted to the study of the sign-object relation in the semiotics of Charles Peirce. It puts this issue in the context of Peirce's philosophy of knowledge and of reality and individuates the final causality as the foundation of the semiotic relation, which gains its gnoseological reliableness from its underlying teleological tendencies.

In this article, I intend to propose an ethical model for digital solidarity. On the one hand, it emphasises the importance of adopting a solidarity model to escape the logic of surveillance capitalism and the race for profits typical of the digital giants’ business model. On the other, it is intended to point out that a model of solidarity embodied in the digital network may instead offer a more universalistic alternative to the types of solidarity that have often imposed themselves (...) in our contemporary political landscape, namely solidarity limited to groups in opposition to others. In order to show what economic and political characteristics this model should respect, two case studies will be examined, namely Wikipedia and Occupy Wall Street. (shrink)

This book presents the thought of the Kyoto School in comparison with continental philosophers better known in the West and addresses the affiliation of some of its members with the militarism of the 1930s and 1940s.

The burden of proof (BOP) fallacy is an informal fallacy involving the failure to recognize or properly assign the BOP in a persuasive reasoned dialogue, that is, an interchange between two or more parties whose aim is to prove or defend a position and, in doing so, persuade the other side of its truth or plausibility. In some such dialogues, the amount or strength of evidence required in order to accomplish this goal reasonably may differ for one of the parties (...) involved. The BOP fallacy can occur in two ways. The first is when one side of the dialogue fails to recognize that its opponent incurs the BOP. The second way the BOP fallacy can occur is when one side of the dialogue assigns the BOP incorrectly. There are still some factors that play a role in determining which side of a dialogue incurs the BOP and this chapter discusses these factors. (shrink)
