Proving the existence of God is a perennial philosophical ambition. An armchair proof would be the jackpot. Ontological arguments promise as much. This Element studies the most famous ontological arguments from Anselm, Descartes, Plantinga, and others besides. While the verdict is that ontological arguments don't work, they get us entangled in fun philosophical puzzles, from philosophy of religion to philosophy of language, from metaphysics to ethics, and beyond.

While Hermann Levin Goldschmidt didn’t read Yiddish anarchists, there seems to have been a convergent evolution in their thinking. Goldschmidt’s looking up to Jewish lore as a source of liberating creativity is commonly encountered in Yiddish anarchist texts. His view of action as a constant response to internal and external challenges in the struggle for an open future is developed by Isaac Nachman Steinberg on the basis of nineteenth-century vitalism. Goldschmidt’s theory of anarchist individualism as willed self-limiting (...) solidarity has a compelling parallel in Hillel Solotaroff’s view of history. His use of impressionism and photography to eternalize the immediacy of human actuality is akin to Rudolf Rocker’s championing of decadent literature. In both cases, the goal of anarchism is not a dictatorship of the former downtrodden, but a continuous and contradictory evolution of freedom in ever-changing contexts. (shrink)

Jürgen Habermas vertritt die These, dass sich das Konsensprinzip des kommunikativen Handelns in den Meinungs- und Willensbildungsprozess der Politik übertragen lasse. In der vorliegenden grundlegenden Kritik zeigt die Autorin, dass diese These nicht haltbar ist. Anders als Habermas annimmt, findet kommunikatives Handeln keinen Eingang in die Prozeduralität der Politik. Das politische Handeln wird vielmehr durch systemische Vorgaben bestimmt. Diese ergeben sich im Wesentlichen aus der Prozeduralität des ökonomischen Systems sowie aus der über Macht bestimmten Prozeduralität des politischen Systems selbst.

Several philosophers have proposed Knowledge-Based Decision Theories (KDTs)—theories that require agents to maximize expected utility as yielded by utility and probability functions that depend on the agent’s knowledge. Proponents of KDTs argue that such theories are motivated by Knowledge-Reasons norms that require agents to act only on reasons that they know. However, no formal derivation of KDTs from Knowledge-Reasons norms has been suggested, and it is not clear how such norms justify the particular ways in which KDTs relate knowledge and (...) rational action. In this paper, I suggest a new axiomatic method for justifying KDTs and providing them with stronger normative foundations. I argue that such theories may be derived from constraints on the relation between knowledge and preference, and that these constraints may be evaluated relative to intuitions regarding practical reasoning. To demonstrate this, I offer a representation theorem for a KDT proposed by Hawthorne and Stanley (2008) and briefly evaluate it through its underlying axioms. -/- In section 1, I present knowledge-based decision theories generally and the versions of such theories suggested in the literature. In section 2, I argue that KDTs and theories of practical reasoning conjoined with Knowledge-Reasons norms generate constraints on the same relation—the relation between knowledge and preference. In section 3, I present a formal framework in which constraints on this relation may be expressed and from which KDTs may be derived. In section 4, I present a representation theorem for a specific KDT. In section 5, I briefly evaluate the axioms of the theory, and in section 6, I conclude. (shrink)

In light of Jewish tradition and the metaphysics of time, we argue that God can and will change the past. The argument makes for a new answer to the problem of evil and a new theory of atonement.

We study the representation of attitudes to risk in Jeffrey’s decision-theoretic framework suggested by Stefánsson and Bradley :602–625, 2015; Br J Philos Sci 70:77–102, 2017) and Bradley :231–248, 2016; Decisions theory with a human face, Cambridge University Press, Cambridge, 2017). We show that on this representation, the value of any prospect may be expressed as a sum of two components, the prospect’s instrumental value and the prospect’s intrinsic value. Both components have an expectational form. We also make a distinction between (...) a prospect’s overall intrinsic value and a prospect’s conditional intrinsic value given each one of its possible outcomes and argue that this distinction has great explanatory power. We explore the relation between these two types of intrinsic values and show that they are determined at the level of preferences. Finally, we explore the relation between the intrinsic values of different prospects and point to a strong restriction on this relation that is implicit in Jeffrey’s axioms. We suggest a natural interpretation to this restriction. (shrink)

At the very beginning of L’Homme-Machine, La Mettrie claims that Leibnizians with their monads have “rather spiritualized matter than materialized the soul”; a few years later Pierre-Louis Moreau de Maupertuis, President of the Berlin Academy of Sciences and natural philosopher with a strong interest in the modes of transmission of ‘genetic’ information, conceived of living minima which he termed molecules, “endowed with desire, memory and intelligence,” in his Système de la nature ou Essai sur les corps organisés. This text first (...) appeared in Latin in 1751 under the title Dissertatio inauguralis metaphysica de universali naturae systemate, with the pseudonym Dr Baumann; it was translated by Maupertuis in 1754 as Essai sur la formation des corps organisés and was later included in his 1756 Œuvres under the title Système de la nature. Now, it is clear that Maupertuis was a kind of Leibnizian; and that his molecule possessed higher-level, ‘mental’ properties. In that sense he falls under the first category described by La Mettrie. But he was also involved in a debate on this issue with Diderot, who put forth a sustained critique of Maupertuis’ theory of the molecule in the additions to his 1753 Pensées sur l’interprétation de la nature. Where Maupertuis attributes higher-level properties to his living minima, Diderot argues that these properties are ‘organizational’, i.e., they can only be properties of the whole. At issue here is the degree of commitment to a form of materialism. (shrink)

This essay shows three things: first, that we cannot comply with a command from God to believe in God; second, that God cannot command us to believe in God; and, third, that the divine command theory is false. The third conclusion follows from the second, and the second follows from the first. The essay focuses on an argument from the medieval Jewish philosopher, Hasdai Crescas. It also draws from, and is something of a sequel to, an argument from Brown and (...) Nagasawa published previously in this journal.†. (shrink)

Experiments have suggested that umbilical cord blood stem cells can be used to prevent diseases such as atherosclerosis. This paper discusses ethical issues surrounding such usage such as the uncertainty that individuals at risk of a disease will actually get the disease; issues related to research with children; safety issues; from where these stem cells would be obtained; and whether these usages should be considered as therapies or as physical enhancements.

Despite its small size, profilin is an amazingly diverse and sophisticated protein whose precise role in cells continues to elude the understanding of researchers 15 years after its discovery. Its ubiquity, abundance and necessity for life in more evolved organisms certainly speaks for its exterme importance in cell function. So far, three ligands for profilin have been well‐characterized in vitro: actin monomers, membrane polyphosphoinositides and poly‐L‐proline. In the years following its discovery, profilin's role in vivo progressed from that of a (...) simple actin‐binding protein which inhibits actin polymerization, to one which, as an important regulator of the cytoskeleton, can even promote actin polymerization under the appropriate circumstances. In addition, interactions with components of the phosphatidylinositol cycle and the RAS pathway in yeast implicate profilin as an important link through which the actin cytoskeleton is able to communicate with major signaling pathways.

Nonexistence is ubiquitous, yet mysterious. This volume explores some of the most puzzling questions about non-being and nonexistence, from metaphysics to ethics and beyond: the contributors offer answers from diverse philosophical perspectives, drawing on analytic, continental, Buddhist, and Jewish philosophical traditions.

Timothy O’Connor presents a novel and powerful version of the cosmological argument from contingency. What distinguishes his argument is that it does not depend on the Principle of Sufficient Reason. This version thus avoids powerful objections facing the Principle. We present and develop the argument, strengthening it in various ways. We fill in big gaps in the argument and answer criticisms. These include the criticisms that O’Connor considers as well as new criticisms. We explain how his replies to a Kantian (...) criticism and to the demand for contrastive explanation fail, and properly answer the criticism and the demand. We develop two new criticisms, the objection from opaqueness and the objection from constitution, and explain how these objections can be answered. (shrink)

Idealism is the view that reality is fundamentally mental. Idealism has been influential historically, but it has been neglected in contemporary metaphysical debate. This volume of 17 essays by leading philosophers rectifies the situation.

Cet ouvrage de Victor Goldschmidt, pour la premiere fois en edition de poche, est le seul consacre a une notion centrale de la philosophie platonicienne, le paradigme, a la fois exemple, comparaison et modele.En prenant comme fil conducteur la definition donnee dans le Politique, l'auteur commence par etudier le role joue par ce procede privilegie dans la methode dialectique des derniers Dialogues. S'exercer sur une realite banale permet de decouvrir la structure d'un grand sujet, plus difficile a definir, comme (...) le sophiste ou l'art politique. Cependant la reussite d'une demarche en saurait en fonder la legitimite. En s'interrogeant sur son fondement, Victor Goldschmidt montre que l'usage d'un paradigme obeit a un mouvement profond de la pensee platonicienne, il nous mene du visible a l'invisible. (shrink)

Many religious traditions teach that we should worship God, and philosophers have explored the requirement to worship God, and what might make God worthy of worship. These religious traditions also prohibit worshipping other gods. This essay explores, from a Jewish perspective, what it might mean to worship other gods, what the rationale behind the prohibition might be, and why the prohibition might be so grave.

The papers in this volume are largely about research ethics and cover questions of consent, reproduction, pediatric research, ethical codes, and clinical relationships. Half the papers have this common aspect: they are conservative—in the sense of supporting the standard, prevailing, or popular view—but they shift the focus—supporting the standard views in terms of moral factors generally neglected by the literature. The volume provides a diverse set of papers for the reader: variously addressing abstract and concrete problems from within different philosophical (...) traditions. (shrink)
