This paper maintains that objectivism about practical reasons should be combined with pluralism both about the nature of practical reasons and about action explanations. We argue for an ‘expanding circle of practical reasons’, starting out from an open-minded monist objectivism. On this view, practical reasons are not limited to actual facts, but consist in states of affairs, possible facts that may or may not obtain. Going beyond such ‘that-ish’ reasons, we argue that goals are also bona fide practical reasons. This (...) makes for a genuine pluralism about practical reasons. Furthermore, the facts or states of affairs that function as practical reasons are not exclusively natural or descriptive, but include normative facts. That normative facts can be reasons justifies a pluralism about reason explanations, one which allows for what we call enkratic explanations in addition to teleological ones. (shrink)

Implementing equity principles in resource allocation is challenging. In one approach, some US states implemented race-based prioritisation of COVID-19 vaccines in response to vast racial inequities in COVID-19 outcomes, while others used place-based allocation. In a nationally representative survey of n=2067 US residents, fielded in mid-April 2021, we explored the public acceptability of race-based prioritisation compared with place-based prioritisation, by offering vaccines to harder hit zip codes before residents of other zip codes. We found that in general, a majority of (...) respondents supported the place-based approach, and a substantial proportion supported the race-based plan. Support was higher among Democrats compared with Republicans. All US residents became eligible for vaccines on 19 April 2021 but as of this writing, equitable uptake of vaccines remains urgent not only for first doses for adults but also for boosters and for children. Our findings also provide a benchmark for future pandemic planning that racial and social justice in vaccine allocation are salient considerations for the public. The findings may furthermore be of interest to policy makers designing vaccine allocation frameworks in countries with comparable health disparities across social, ethnic and racial groups, and more broadly, for those exploring ways of promoting equity in resource allocation outside of a pandemic setting.

Charles Sanders Peirce is best known as the founder of pragmatism, but the name that he preferred for his overall system of thought was ‘‘synechism’’ because the principle of continuity was its central thesis. He considered time to be the paradigmatic example and often wrote about its various aspects while discussing other topics. This essay draws from many of those widely scattered texts to formulate a distinctively Peircean philosophy of time, incorporating extensive quotations into a comprehensive and coherent synthesis. Time (...) is not an existential subject with past, present, and future as its incompatible predicates, but rather a real law enabling things to possess contrary qualities at its different determinations, and Peirce identifies four classes of such states based on when and how they are realized. Because time is continuous, it is not composed of instants, and even the present is an indefinite lapse during which we are directly aware of constant change. The accomplished past is perpetually growing as the possibilities and conditional necessities of the future are actualized at the present, and the entire universe evolves from being utterly indeterminate toward being absolutely determinate. Nevertheless, time must return into itself even if events are limited to only a portion of it, a paradox that is resolved with the aid of projective geometry. Temporal synechism thus touches on a broad spectrum of philosophical issues including mathematics, phenomenology, logic, and metaphysics. (shrink)

In this paper, I discuss the conceptualist claim that we cannot speak of perceptual content unless we assume it is objective content. The conceptualist argues that only conceptual content can meet the requirement of being objective, so that the view that perceptual experience has nonconceptual content is not tenable. I start out by presenting the argument from objectivity as it can be found in McDowell. I then present the following objections: First, perceptual objectivity cannot be due to the perceiver’s conception (...) of objectivity; and second, even nonconceptual capacities of the individual cannot and need not be appealed to in order to account for objective perceptual content.

We prove completeness and decidability results for a family of combinations of propositional dynamic logic and unimodal doxastic logics in which the modalities may interact. The kind of interactions we consider include three forms of commuting axioms, namely, axioms similar to the axiom of perfect recall and the axiom of no learning from temporal logic, and a Church–Rosser axiom. We investigate the influence of the substitution rule on the properties of these logics and propose a new semantics for the test (...) operator to avoid unwanted side effects caused by the interaction of the classic test operator with the extra interaction axioms.

Mit einer virtuellen Welt kann sehr Verschiedenes und Mannigfaltiges assoziiert werden, unter anderem ein weiterer schillernder Begriff: Die Utopie. Sind nun virtuelle Welten allesamt Utopien? Oder müsste man vielmehr umgekehrt die Utopie als eine besondere virtuelle Welt hervorheben? Dass es überhaupt einen engen Zusammenhang zwischen den beiden Begriffen gibt, scheint nicht einmal selbstverständlich: Es gibt ihn sicherlich nicht, wenn man unter einer virtuellen Welt lediglich ein mit Hilfe von Computertechnik generiertes Szenario und unter einer Utopie schlicht und einfach eine der (...) Wirklichkeit unangemessene Wunschvorstellung versteht oder aber die Utopie als die literarische Konzeption einer für ideal befundenen Gesellschaftsform begreift und ideengeschichtlich demgemäß mit Platons „Staat“ beginnen lässt. Damit das begriffliche Verhältnis zwischen den heute durchaus auch im allgemeinen Sprachgebrauch verwurzelten Ausdrücken „Utopie“ und „Virtualität“ untersucht werden kann, soll der Versuch unternommen werden, anschaulich zu machen, wie sie verwendet werden könnten.

The goal of this paper is an interpretation of Aristotle's modal syllogistics closely oriented on the text using the resources of modern modal predicate logic. Modern predicate logic was successfully able to interpret Aristotle's assertoric syllogistics uniformly , that is, with one formula for universal premises. A corresponding uniform interpretation of modal syllogistics by means of modal predicate logic is not possible. This thesis does not imply that a uniform view is abandoned. However, it replaces the simple unity of the (...) assertoric by the complex unity of the modal. The complexity results from the fact that though one formula for universal premises is used as the basis, it must be moderated if the text requires . Aristotle introduces his modal syllogistics by expanding his assertoric syllogistics with an axiom that links two apodictic premises to yield a single apodictic sentence . He thus defines a regular modern modal logic. By means of the regular modal logic that is thus defined, he is able to reduce the purely apodictic syllogistics to assertoric syllogistics. However, he goes beyond this simple structure when he looks at complicated inferences. In order to be able to link not only premises of the same modality, but also premises with different modalities, he introduces a second axiom, the T-axiom, which infers from necessity to reality or - equivalently - from reality to possibility. Together, the two axioms, the axiom of regularity and the T-axiom, define a regular T-logic. It plays an important role in modern logic. In order to be able to account for modal syllogistics adequately as a whole, another modern axiom is also required, the so-called B-axiom. It is very difficult to decide whether Aristotle had the B-axiom. The two last named axioms are sufficient to achieve the required contextual moderation of the basic formula for universal propositions. (shrink)

Für Teichmüller waren die Religionen das «Erz» der Philosophie. Alle Weltauffassungen seien in vorwissenschaftlicher Form in ihnen enthalten und müssten von der Philosophie «in Begriffen gewonnen werden». Dies unternimmt die 1886 erschienene Religionsphilosophie. Sie schliesst an Die wirkliche und die scheinbare Welt an und ist Teil von Teichmüllers Projekt der Entwicklung einer neuen, personalistischen Philosophie. Aus dieser Perspektive analysiert er auch die Religionen. Dafür zieht er nicht nur Texte, sondern auch zahlreiche religiöse Verhaltensweisen, Kulte und Artefakte heran. Die Zurücknahme der (...) Projektion des Gottesbewusstseins und das zunehmende Bewusstsein um das eigene Ich bestimmen nach Teichmüller die religiöse Entwicklung. Dabei unterscheidet er eine projektivische, eine pantheistische und eine personalistische Stufe der Religion. Der zweite geplante Band der Religionsphilosophie sollte das Christentum als Vertreterin der personalistischen Religion behandeln. Wegen des unerwarteten Todes Teichmüllers blieb er ungeschrieben. Als Ersatz wird der Religionsphilosophie ein aus dem Nachlass ediertes Manuskript seiner Vorlesungen über Philosophie des Christenthums beigefügt, die zeitlich und inhaltlich unmittelbar an die Religionsphilosophie anschlossen. Teichmüllers entmythologisiertes Christentum ist nicht nur die Religion der selbständigen, ewigen menschlichen Person. Es befreit auch von der Angst vor Gottes Strafe, von der Qual des Sündenbewusstseins und dem Bangen um Erlösung und emanzipiert das Individuum von totalitären religiösen Institutionen. (shrink)

As synthetic biology develops into a promising science and engineering field, we need to have clear ideas and priorities regarding its safety, security, ethical and public dialogue implications. Based on an extensive literature search, interviews with scientists, social scientists, a 4 week long public e-forum, and consultation with several stakeholders from science, industry and civil society organisations, we compiled a list of priority topics regarding societal issues of synthetic biology for the years ahead. The points presented here are intended to (...) encourage all stakeholders to engage in the prioritisation of these issues and to participate in a continuous dialogue, with the ultimate goal of providing a basis for a multi-stakeholder governance in synthetic biology. Here we show possible ways to solve the challenges to synthetic biology in the field of safety, security, ethics and the science-public interface. (shrink)

Mit dem treffenden Ausdruck "Der wunderbare florentinische Geist" bezeichnet Jacob Burckhardt den Geist der Erneuerung in Florenz zur Zeit der italienischen Renaissance - des Rinascimento. Er revolutionierte die unterschiedlichsten kulturellen Bereiche, wie etwa das politische Denken, Wissenschaft, Technik und Kunst. Dieser Geist wirkt bis heute fort. In seiner vielfältigen Gestalt dient er als Ausgangspunkt, um den Hintergrund der europäischen Kultur zu erkunden.
