Mathematicians justify axioms of set theory “intrinsically”, by reference to the universe of sets of their intuition, and “extrinsically”, for example, by considerations of simplicity or usefullness for mathematical practice. Here we apply the same kind of justifications to Nonstandard Analysis and argue for acceptance of BNST+ . BNST+ has nontrivial consequences for standard set theory; for example, it implies existence of inner models with measurable cardinals. We also consider how to practice Nonstandard Analysis in BNST+, and compare it with (...) other existing nonstandard set theories. (shrink)

Currently the two popular ways to practice Robinson’s nonstandard analysis are the model-theoretic approach and the axiomatic/syntactic approach. It is sometimes claimed that the internal axiomatic approach is unable to handle constructions relying on external sets. We show that internal frameworks provide successful accounts of nonstandard hulls and Loeb measures. The basic fact this work relies on is that the ultrapower of the standard universe by a standard ultrafilter is naturally isomorphic to a subuniverse of the internal universe.

We prove that Standardization fails in every nontrivial universe definable in the nonstandard set theory BST, and that a natural characterization of the standard universe is both consistent with and independent of BST. As a consequence we obtain a formulation of nonstandard class theory in the ∈-language.

We study combinatorial principles related to the isomorphism property and the special model axiom in nonstandard analysis.

Cultuurkritisch essay vanuit de optiek van de anti-psychiatrie.

En lisant la République et le Timée de Platon, ce livre propose une enquête sur les deux formes de temporalité irréductibles (celle de la cité armée, celle de l'âme immortelle) pour éclairer la question principale, celle de la nature et de la structure de l'âme, de la cité et du cosmos.

The COVID-19 pandemic has highlighted the difficult task of balancing access to misinformation with respect for patient decision-making. Due to its innate antagonism, the paradigm of “physician paternalism” versus “patient autonomy” may not adequately capture the clinical relationship. The authors hypothesized that most patients would, in fact, prefer significant physician input as opposed to unopinionated information when making medical decisions. There is a lack of empirical data corroborating this in the United States. To that end, a survey was distributed to (...) 650 individuals through Amazon Mechanical Turk, of which 499 responses met pre-determined quality criteria. Most respondents believed their doctor's insight would be better than their own if injured or gravely ill. When asked to affirm preferences separately, a significantly higher proportion of respondents preferred guidance from their doctor when making medical decisions compared to being presented with unopinionated information ( p < 0.001). Encouragingly, 93.1% believed that the doctor's primary goal was their health. When asked directly to compare physician guidance to unopinionated information, 69.1% respondents stated they would prefer physician guidance. We found a consistent association between educational/economic background and affirmative responses ( p < 0.001), suggesting particular attention should be paid to patients that are disadvantaged with respect to these demographic factors. The belief in a shared goal, and a consistent preference for physician input, suggests that patients endorse a more collaborative view of the clinical dynamic than is suggested by the paternalism-autonomy paradigm. This pilot study suggests physicians should not be afraid to communicate conviction with regard to treatment decisions. (shrink)

Public debate on acceptable farm animal husbandry suffers from a confusion of tongues. To clarify positions of various stakeholder groups in their joint search for acceptable solutions, the concept of animal welfare was split up into three notions: no suffering, respect for intrinsic value, and non-appalling appearance of animals. This strategy was based on the hypothesis that multi-stakeholder solutions should be based on shared values rather than on compromises. The usefulness of such an artificial value distinction strategy was tested in (...) a small series of experiments. The results demonstrate that the chosen concept to distinguish between values is effective in a stakeholder context. Farmers’ views on doing good to animals appeared to be largely based on their value to prevent suffering and predominantly focused on the provision of regular care. Their priority for this value is clearly shared with other stakeholders, providing a basis for joint solutions. The concept of intrinsic value does not play a discernable role in farmers’ considerations. Based on the varying views on welfare, it can be inferred that there is a gradual rather than a principal difference between government legislation and farmers’ values, whereas public perception and acceptance of farm practices remains complicated. Distinction between value groups and focusing on a selected notion (such as no suffering) proved to be effective in bringing representatives of stakeholder groups together, but is unlikely to bridge the emotional gap between commercial farm practices and public ideals.

This paper provides a finer analysis of the well-known form of the Local Deduction Theorem in contraction-free logics . An infinite hierarchy of its natural strengthenings is introduced and studied. The main results are the separation of its initial four members and the subsequent collapse of the hierarchy.

Pojem řádu má své veliké dějiny od předsókratiků až k H. Kringsovi, který v roce 1941 vydává knihu Ordo. U nás se pojmu řádu a řádovosti věnoval po celý život ze­jména brněnský a olomoucký myslitel J. L. Fischer (1894–1973). Idea řádu byla také jedním z pilířů jeho skladebné filosofie, jež měla základní problémy moderní společnosti vyřešit účinněji než marxismus. Současně s „laickým“ Fischerem usilovala v kritických 30. letech dvacátého století o nastolení kýženého řádu vyhraněně katolická skupina sou­středěná kolem tehdy nově (...) založené revue Řád. Oběma pólům šlo sice o podobný cíl (skoncovat s vládou neblahého kapitalismu), ale neporozuměly si pro různost svých věr. Toto osudové neporozumění bychom měli především na univerzitách v Brně a Olomou­ci napravovat využitím odkazu W. C. Smithe, který zásadně rozlišil setrvačnou tradiční víru (belief) a otevřenou víru všech opravdu tvůrčích lidí (faith). Takovou víru měl totiž podle autora také a snad především nový řád usilovně hledající Josef Ludvík Fischer. (shrink)

Molecular Revolution in BrazilFélix Guattari and Suely Rolniktranslated by Karel Clapshow and Brian HolmesYes, I believe that there is a multiple people, a people of mutants, a people of potentialities that appears and disappears, that is embodied in social, literary, and musical events.... I think that we're in a period of productivity, proliferation, creation, utterly fabulous revolutions from the viewpoint of this emergence of a people. That's molecular revolution: it isn't a slogan or a program, it's something that I (...) feel, that I live....--from Molecular Revolution in BrazilFollowing Brazil's first democratic election after two decades of military dictatorship, French philosopher Félix Guattari traveled through Brazil in 1982 with Brazilian psychoanalyst Suely Rolnik and discovered an exciting, new political vitality. In the infancy of its new republic, Brazil was moving against traditional hierarchies of control and totalitarian regimes and founding a revolution of ideas and politics. Molecular Revolution in Brazil documents the conversations, discussions, and debates that arose during the trip, including a dialogue between Guattari and Brazil's future President Luis Ignacia Lula da Silva, then a young gubernatorial candidate. Through these exchanges, Guattari cuts through to the shadowy practices of globalization gone awry and boldly charts a revolution in practice.Assembled and edited by Rolnik, Molecular Revolution in Brazil is organized thematically; aphoristic at times, it presents a lesser-known, more overtly political aspect of Guattari's work. Originally published in Brazil in 1986 as Micropolitica: Cartografias do desejo, the book became a crucial reference for political movements in Brazil in the 1980s and 1990s. It now provides English-speaking readers with an invaluable picture of the radical thought and optimism that lies at the root of Lula's Brazil. Félix Guattari, post-'68 French psychoanalyst and philosopher, is the author of Anti-Oedipus, The Anti-Oedipus Papers, 2006), and other books. Semiotext has published the first two volumes of his complete essays, Chaosophy and Soft Subversions, and will publish the final volume, Chaos and Complexity, in 2008. Suely Rolnik is a psychoanalyst, cultural critic, and curator who lives and works in São Paulo, Brazil. She was a close collaborator of Guattari during her exile in Paris from the military dictatorship in Brazil. (shrink)

Dostoevsky wrote that love in action is a harsh and terrible thing compared to love in dreams. That reality is particularly evident in medicine, where there is an almost universal, involuntary participation of physicians and other healthcare workers in the suffering of their patients. This paper explores this phenomenon through the paradigm of ‘mystery’ as explained by the French existentialist philosopher Gabriel Marcel. A mystery is different from a problem in the sense that the former requires the active immersion of (...) the person involved in order to be truly experienced. It is a ‘meta-problem’ that cannot be analyzed objectively and separately from the person that it affects, without changing the nature of the thing experienced. The authors contend that the human suffering encountered in medicine is one such phenomenon, and the paper draws on illustrations of this concept in art and literature. Awareness of the subtle but important difference between mystery and problem may help physicians better understand their personal entanglement with the suffering of patients. (shrink)

In Liberalism’s religion, Laborde defends a liberal egalitarian position and tackles, from a new perspective, some issues dealt with in his republican writings. This article examines some of these issues, paying attention to the place that the recognition of identities occupies both in her republican and in her liberal theories, as well as the type of justification advanced in both cases. The article shows that the recognition of identities has gone from having a peripheral and instrumental role in her republican (...) writings to having a central role in her liberal theory. (shrink)

Intentionally or not, our clinical practice is informed by our philosophical premises. A subtle misunderstanding can have frequent, though insidious, implications in day-to-day clinical encounters....

Many biologists still believe in a sort of post-Cartesian foundation of reality wherein objects are independent of subjects which cognize them. Recent research in behaviour, cognition, and psychology, however, provides plenty of evidence to the effect that the perception of an object differs depending on the kind of animal observer, and also its personality, hormonal, and sensorial set-up etc. In the following, I argue that exposed surfaces of organisms interact with other organisms’ perception to form semiautonomous relational entities called semantic (...) organs, which participate in biological reality as discrete heritable evolutionary units. The inner dimensions and potentialities of an organism can enter the senses of another living being when effectively expressed on the outer surfaces of the former and meaningfully perceived by the latter. Semantic organs have three basic sources of variability: intrinsic, i.e., genetic, epigenetic, and developmental processes; extrinsic, meaning the biotic and abiotic environmental conditions which affect the developmental generators of intrinsic variability; and perceptual, stemming from differences in the subject-specific interpretation of a SO’s structural basis. Extrinsic and intrinsic sources of variability are, however, just precursors to semantic organs. SOs are relational entities which always come into existence through an act of perception and their actual form depends both on the physical potentialities of the bearer and the species- or group-specific interpretation of the receiver.

In the Belgian constitutional order, there is no room for any direct political powers to be exercised by the King. Even on the occasion of a crisis- when the Cabinet tenders its resignation or when the Kingperforms His constitutional mission in the process towards the formation of a new government ; His freedom of action is restricted by the objective context, defined mainly by the political parties.The King, however, retains the possibility of exercising his political influence. This influence may be (...) all the more important in a country, such as Belgium, where the parliamentary system of proportional representation and the constitutional rule that both major linguistic groups be equally represented in the Cabinet -amongst other factors - cause a cabinet formation to be a complex and delicate process.
