Introduction générale à la philosophie des sciences du 20e siècle.

Answer-set programming (ASP) has emerged as a declarative programming paradigm where problems are encoded as logic programs, such that the so-called answer sets of theses programs represent the solutions of the encoded problem. The efficiency of the latest ASP solvers reached a state that makes them applicable for problems of practical importance. Consequently, problems from many different areas, including diagnosis, data integration, and graph theory, have been successfully tackled via ASP. In this work, we present such ASP-encodings for problems associated (...) to abstract argumentation frameworks (AFs) and generalisations thereof. Our encodings are formulated as fixed queries, such that the input is the only part depending on the actual AF to process. We illustrate the functioning of this approach, which is underlying a new argumentation system called ASPARTIX in detail and show its adequacy in terms of computational complexity. (shrink)

The paper proposes to integrate literary studies in consciousness research to develop a strong ethical and existential dimension in the field. More specifically, it considers the value of fictional narrative for developing concepts of selfhood and personal identity that cohere with the reductionist explanations of human consciousness and self in modern empirical consciousness research. My central claim is that looking to the literary representations of human consciousness and existence that reject or are free from conventional essentialist ideas of self, agency, (...) and anthropocentrism can help 'normalize' the reductionist scientific descriptions of humans and reduce their psychologically and socio-culturally disruptive impact. The paper uses Virginia Woolf's The Waves as an example, showing how the novel's non-anthropocentric and non-essentialist conceptions of self and consciousness overlap with materialist theories in neuroscience and -philosophy but present these in a distinctive narrative framework and poetic terms that bring out the inherent emancipatory potential of the materialist explanation of human existence and offer the reader the possibility of relating to these experientially and emotionally.

Einstein Versus Bohr is unlike other books on science written by experts for non-experts, because it presents the history of science in terms of problems, conflicts, contradictions, and arguments. Science normally "keeps a tidy workshop." Professor Sachs breaks with convention by taking us into the theoretical workshop, giving us a problem-oriented account of modern physics, an account that concentrates on underlying concepts and debate. The book contains mathematical explanations, but it is so-designed that the whole argument can be followed with (...) the math omitted. Professor Sachs' story begins with classical and nineteenth century physics, describes the early discoveries in particle theory, and introduces the "old" quantum theory, which evolved into the quantum mechanics of the Copenhagen School. Such important ideas as the Einstein Photon Box experiment and the Einstein-Podolsky-Rosen Paradox, and Schrodinger's Cat Paradox are clearly expounded, followed by a completely fresh explanation of relativity in conceptual terms, showing how apparent paradoxes can be removed by Einstein's own interpretation, especially that of his later years. Professor Sachs gives a detailed comparison of the fundamentals of the quantum and relativity theories, suggesting how the contradictions might be resolved. In an epilogue, he makes suggestions, with reference to religious notions, Taoism, and Buber's theory of I-Thou, for generalizing Einstein's approach beyond physics. (shrink)

Structural Realism (SSR), as embodied in the Ramsey-sentence H* of a theory H, is defended against the view that H* reduces to a trivial statement about the cardinality of the domain of H, a view which arises from ignoring the central role of observation within science. Putnam’s theses are examined and shown to support rather than undermine SSR. Finally: in view of its synthetic character, applied mathematics must enter into the formulation of H* and hence be shown to be finitely (...) axiomatisable; this is done in the Appendix, which is the most important part of the paper.

The Ramsey-sentence H* of any hypothesis H is shown to be a synthetic proposition containing mathematics as a finite component. Far from being quasi-tautological, H* proves to have as much physical content as H itself.

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

With the rise of the scientific authority of neuroscience and recent neurotechnological advances, the understanding of the human being and its future is beginning to undergo a radical change. As a result, a normative and existential vacuum is opening and hopes as well as fears about the future are flourishing. Some philosophers are anticipating a broad neuroscientific disenchantment, sociocultural disruption and a new existential anxiety related to the clash of the neuroscientific and humanistic image of humans. Others are expecting the (...) technological and scientific developments to lead to human enhancement and existential emancipation. In the first part of this commentary, I outline these two contrasting responses to the rise of neurocentricism and non-anthropocentrism. In the second part, I argue that the divide between the old anthropocentric paradigm and the emerging neuroscientific is misconceived and that literature and fictional narrative are particularly illustrative of the possibility of integrating scientific materialism with humanism. I use the contemporary literary-philosophical work The Creative Act by Rick Rubin to show that humanist ideas can indeed cohere with anti-essentialist and neuroscientific notions of personal identity and self and how existential meaning and comfort can be found in a neuroscientifically and deterministically explained world.

We thank Leo Lam and Taylor Nichols for their response1 to our paper ‘COVID-19 vaccine boosters for young adults: a risk–benefit assessment and ethical analysis of mandate policies at universities’.2 In our paper, we demonstrate that the risk–benefit calculus to mandate boosters for young adults aged 18–29 is a net risk intervention. The authors assert that we have made three inappropriate comparisons of benefits versus risks of the mRNA vaccine booster dose in this age group. We provide our response to (...) each below. We erred on the side of overestimating benefits of the booster dose against severe COVID-19 in this age group and still found net harms to outweigh net benefits. The conclusion of our paper holds, and university booster mandates for young people were—and remain—unethical. For the first comparison, we weighed predicted hospitalisations prevented by one booster dose of BNT162b2 with vaccine-associated SAEs from the manufacturer’s randomised trial (3/5055).3 We found that the rate of expected SAEs would outweigh the benefits of the booster against hospitalisation by at least 18-fold. Lam and Nichols suggest that this was an inappropriate comparison, as not all SAEs result in hospitalisation. However, the definition of SAE as used in the trial included death, hospitalisation, disability, permanent damage, life-threatening event or condition, which required medical or surgical intervention to prevent a serious outcome.4 While all comparisons include some degree of incommensurability, comparing these SAEs with hospitalisations prevented by the booster is more reasonable than Lam and Nichols’ suggestion of comparing SAEs to infections prevented. The COVID-19 infection hospitalisation risk in this age group was <0.5% (or <1/200)5 even prior to widespread immunity, thus comparing SAEs to infection risk is entirely inappropriate. Furthermore, a booster dose will only offer transient (if any) protection against infection6 and cumulative infection rates …. (shrink)

In this article I challenge the standard view that clarity and coherence in moral philosophy and ethics are always good and obscurity necessarily bad. The appraisal of clarity, I argue, entails a risk of reducing and misrepresenting the complex and multifaceted nature of good, productive and true thinking and communication. Uncertainty and obscurity do not necessarily lead to vagueness, imprecision or meaning-obstruction. There are productive forms of uncertainty and there are unproductive forms. Indeed, to be precise, lucid and truthful sometimes (...) requires respecting and linguistically and conceptually reproducing the incoherence, obscurity and uncertainty of reality. (shrink)

With the analysis of the scattering ashes in a Norwegian context as its point of departure, the article sets out to explore ash scattering and how it relates to the governance of deathscape and religion/worldview in the public space. Referring to ethnographic study, the focus is on the bereaved and the deceased in the governance process for ash scattering and on critically rethinking the governance of ash scattering from the private actors’ experiences. I argue that ash scattering is in the (...) process of establishing a spatial ritual institution, deregulated vis-à-vis organized religion/worldview, which, on the one hand, opens up the possibility for the privatization of death and provides ideals of individuality, privacy and discretion, and, on the other hand, this takes place paradoxically not in private but rather within public space.

Health research is increasingly being conducted on a global scale, particularly in the developing world to address leading causes of morbidity and mortality. While research interest has increased, building scientific capacity in the developing world has not kept pace. This often leads to the export of human tissue (defined broadly) from the developing to the developed world for analysis. These practices raise a number of important ethical issues that require attention.

Proofs and Refutations is essential reading for all those interested in the methodology, the philosophy and the history of mathematics. Much of the book takes the form of a discussion between a teacher and his students. They propose various solutions to some mathematical problems and investigate the strengths and weaknesses of these solutions. Their discussion raises some philosophical problems and some problems about the nature of mathematical discovery or creativity. Imre Lakatos is concerned throughout to combat the classical picture of (...) mathematical development as a steady accumulation of established truths. He shows that mathematics grows instead through a richer, more dramatic process of the successive improvement of creative hypotheses by attempts to 'prove' them and by criticism of these attempts: the logic of proofs and refutations.

Structural Realism (SSR), as embodied in the Ramsey-sentence H of a theory H, is defended against the view that H reduces to a trivial statement about the cardinally of the domain of H, a view which arises from ignoring the central role of observation within science. Putnam's theses are examined and shown to support rather than undermine SSR. Finally: in view of its synthetic character, applied mathematics must enter into the formulation of H and hence to be shown axiomatisable; this (...) is done in the Appendix, which is the most important part of the paper.

It has been maintained, by bothphilosophers and modern scjentists, that the twa domains of discourse of science and of philosophy are disjoint. Though admitting that many physicists subscribed to metaphysical principies, it was claimed - by Duhem and Reichenbach among others - that the scientist's philosophical convictions play, or shouldplay, no role in his scientiflc work. The presentpaper attempts lo refute this separatist view by showing that Einstein 's metaphysical realism - caupied with his Platonistic panmathematicism - played a crucial (...) role in his construction of the Relativity Programme and in his criticism of Quantum Mechanics (EPRparadox). The article also shows that although Einstein was neither a strict Humean nor a strict Machian, his phenomenalist interpretation of the empirical basis proved ta be an antidote against bath conventianalist scepticism and Neurath's coherence theory of (scientific) truth.

In this paper I try to explain why Lakatos’s conventionalist view must be replaced by a phenomenological conception of the empirical basis; for only in this way can one make sense of the theses that the hard core of an RP can be shielded against refutations; that this metaphysical hard core can be turned into a set of guidelines or, alternatively, into a set of heuristic metaprinciples governing the development of an RP; and that a distinction can legitimately be made (...) between novel predictions and facts to which a theory might have been adjusted post hoc. Two basic metaprinciples are finally examined: the Correspondence Principle and various symmetry requirements; both of these heuristic devices illustrate the fundamental role which, according to Lakatos, mathematics plays in the progress of empirical science.

Since the spectrum of possibilities in linguistic theory construction is much broader and more variegated than students of linguistics have perhaps been led to believe, the Current Issues in Linguistic Theory series has been established in order to provide a forum for the presentation and discussion of linguistic opinions of scholars who do not necessarily accept the prevailing mode of thought in linguistic science. CILT is a theory-oriented series which welcomes contributions from scholars who have significant proposals to make towards (...) the advancement of our understanding of language, its structure, functioning, and development. Current Issues in Linguistic Theory is especially designed, by offering an alternative outlet for meaningful contributions to the current linguistic debate, to furnish the community of linguists the diversity of opinion which a healthy discipline must have.
