Subject-sensitive invariantism posits surprising connections between a person’s knowledge and features of her environment that are not paradigmatically epistemic features. But which features of a person’s environment have this distinctive connection to knowledge? Traditional defenses of subject-sensitive invariantism emphasize features that matter to the subject of the knowledge-attribution. Call this pragmatic encroachment. A more radical thesis usually goes ignored: knowledge is sensitive to moral facts, whether or not those moral facts matter to the subject. Call this moral encroachment. This paper (...) argues that, insofar as there are good arguments for pragmatic encroachment, there are also good arguments for moral encroachment. (shrink)

This book develops an argument for a foundational theory of modality using higher-order logic. The use of higher-order logic in metaphysics is motivated, and a particular higher-order logic is introduced. Fine-grained theories of propositional individuation are shown to be problematic, and a course-grained theory of propositional individuation is defended. On the basis of this theory, it is argued that the metaphysical necessities can be delineated using purely logical terms; by adding an actuality operator, it is shown that the logic of (...) metaphysical necessity is S5. The theoretical role of possible worlds is articulated, and shown to be satisfied by maximal propositions if it satisfied by anything; the existence of such maximal propositions is demonstrated using plural propositional quantification. The resulting theory reduces metaphysical modal terms to higher-order logical terms, and thereby vindicates a widespread modal conception of metaphysics. (shrink)

Two expressive limitations of an infinitary higher-order modal language interpreted on models for higher-order contingentism – the thesis that it is contingent what propositions, properties and relations there are – are established: First, the inexpressibility of certain relations, which leads to the fact that certain model-theoretic existence conditions for relations cannot equivalently be reformulated in terms of being expressible in such a language. Second, the inexpressibility of certain modalized cardinality claims, which shows that in such a language, higher-order contingentists cannot (...) express what is communicated using various instances of talk of ‘possible things’, such as ‘there are uncountably many possible stars’.

Call the following claim Asymmetry: rationality often requires a more steadfast response to pure moral disagreement than it does to otherwise analogous non-moral disagreement. This paper briefly motivates Asymmetry and explores its implications for meta-ethics. Some philosophers have thought that anti-realists are better-placed than realists to explain Asymmetry because, if anti-realism is true, disagreement cannot provide evidence against the reliability of one's thinking about objective moral facts. This paper argues that this simple diagnosis fails to support otherwise plausible anti-realisms. It (...) closes by discussing an alternative explanation for Asymmetry, which appeals to the moral importance of steadfastness. (shrink)

This article explores the connection between two theses: the principle of conditional excluded middle for the counterfactual conditional, and the claim that it is a contingent matter which (coarse grained) propositions there are. Both theses enjoy wide support, and have been defended at length by Robert Stalnaker. We will argue that, given plausible background assumptions, these two principles are incompatible, provided that conditional excluded middle is understood in a certain modalized way. We then show that some (although not all) arguments (...) for conditional excluded middle can in fact be extended to motivate this modalized version of the principle. (shrink)

Many writers have recently argued that there is something distinctively problematic about sustaining moral beliefs on the basis of others’ moral views. Call this claim pessimism about moral deference. Pessimism about moral deference, if true, seems to provide an attractive way to argue for a bold conclusion about moral disagreement: moral disagreement generally does not require belief revision. Call this claim steadfastness about moral disagreement. Perhaps the most prominent recent discussion of the connection between moral deference and moral disagreement, due (...) to Alison Hills, uses pessimism about the former to argue for steadfastness about the latter. This paper reveals that this line of thinking, and others like it, are unsuccessful. There is no way to argue from a compelling version of pessimism about moral deference to the conclusion of steadfastness about moral disagreement. The most plausible versions of pessimism about moral deference have only very limited implications for moral disagreement. (shrink)

According to the algebraic approach to spacetime, a thoroughgoing dynamicism, physical fields exist without an underlying manifold. This view is usually implemented by postulating an algebraic structure (e.g., commutative ring) of scalar-valued functions, which can be interpreted as representing a scalar field, and deriving other structures from it. In this work, we point out that this leads to the unjustified primacy of an undetermined scalar field. Instead, we propose to consider algebraic structures in which all (and only) physical fields are (...) primitive. We explain how the theory of natural operations in differential geometry—the modern formalism behind classifying diffeomorphism-invariant constructions—can be used to obtain concrete implementations of this idea for any given collection of fields. For concrete examples, we illustrate how our approach applies to a number of particular physical fields, including electrodynamics coupled to a Weyl spinor. (shrink)

Many theorists writing about moral responsibility accept that voluntary control is necessary for responsibility. Call such theorists volitionists. Recently, volitionism has been called into question by theorists I call nonvolitionists. Yet neither volitionists nor nonvolitionists have carefully articulated a clear volitionist thesis, nor have they sufficiently explained the concept of voluntary control that somehow seems connected to volitionism. I argue that attempts to explain the volitionist thesis, voluntary control, and their relation are more problematic than have previously been recognized. Instead, (...) I recommend understanding volitionism in terms of intentional actions and omissions. This understanding has several benefits. It clarifies the debate and its parameters, it avoids the problematic notion of voluntary control while relying on the clearer notion of intentional action, and it highlights that the debate between volitionists and nonvolitionists essentially concerns the nature and scope of obligations. As a result, understanding volitionism in terms of intentional actions and omissions can help breathe new life into the volitionist debate. (shrink)

Tae Wan Kim, John Hooker, and Thomas Donaldson make an attempt, in recent articles, to solve the alignment problem. As they define the alignment problem, it is the issue of how to give AI systems moral intelligence. They contend that one might program machines with a version of Kantian ethics cast in deontic modal logic. On their view, machines can be aligned with human values if such machines obey principles of universalization and autonomy, as well as a deontic utilitarian principle. (...) Programming machines to do so might be useful, in their view, for applications such as future autonomous vehicles. Their proposal draws both on traditional logic-based and contemporary connectionist approaches, to fuse factual information with normative principles. I will argue that this approach makes demands of machines that go beyond what is currently feasible, and may extend past the limits of the possible for AI. I also argue that a deontological ethics for machines should place greater stress on the formula of humanity of the Kantian categorical imperative. On this principle, one ought never treat a person as a mere means. Recognition of what makes a person a person requires ethical insight. Similar insight is needed to tell treatment as a means from treatment as a mere means. The resources in Kim, Hooker, and Donaldson’s approach is insufficient for this reason. Hesitation regarding deployment of autonomous machines is warranted in light of these alignment concerns. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Origen and Prophecy: Fate, Authority, Allegory, and the Structure of Scripture by Claire HallMilanna FritzOrigen and Prophecy: Fate, Authority, Allegory, and the Structure of Scripture by Claire Hall (Oxford: Oxford University Press, 2021), 195 pp.Origen's (AD 185–255) surviving corpus is studied by scholars across the disciplines of theology philosophy and classics. Drawing from each of these fields, in Origen and Prophecy, Clare Hall applies Origen's self-proposed tripartite exegesis (...) of Scripture, in which verses can be read at a "somatic, psychic, or pneumatic level," to his conceptualization of prophecy [End Page 293] (193). Hall's argument examines the "landscape of pagan, Jewish, and early Christian religiosity" and considers the "whole range of Origen's corpus" in relation to "wider structures and themes in his work" (4, 25). In doing so, Hall presents a compelling analysis embedding Origen's system of exegesis and theology of prophecy within the intellectual history of prophecy in the late classical and early Christian world.In her first few chapters, Hall explores Origen's definitions of prophecy in relation to its Jewish and Greco-Roman influences and his system of scriptural exegesis. Hall remains cognizant of terminology used by classical authors as she describes Origen's word choice, noting, for instance, that he varies his language most when the prophetic validity of the author is in question (9–12). She summarizes Greek, Roman, and Jewish conceptualizations of prophecy, then turns to Scripture and early Christian texts, all of which shape Origen's own "notions of wisdom, knowledge, and prophecy" (20, 29). Hall argues that Origen's On First Principles and homilies on Exodus, Leviticus, and Numbers are underlaid by a coherent exegetical system. Further, she explains, Origen's Commentary on the Song of Songs applies this same system to other forms of knowledge, including prophecy, which has a future-telling sense, a moral sense, and a mystical and revelatory sense (27, 50, 39–45). In her analysis, Hall provides insight into the philosophical and theological foundations for the "revelatory potential of allegory" as understood by Origen and other early Christian authors and carefully distinguishes Origen's own beliefs from the tenets of Origenism (30–31). To strengthen her argument, Hall cites a plethora of secondary scholars on Origen, including Caroline Bammel, Gunnar af Hällström, Robert Hauck, and Ilaria Ramelli (18–25).In her next few chapters, Hall unfolds Origen's system of distinguishing between true and false prophets and his advocacy for the unity of prophecy within Scripture in his response to Marcionism (199, 149–52). Chief among Hall's insightful contributions, however, is her treatment of the complex interrelation of prophecy and human autonomy: within Origen's framework, how does providential foreknowledge permit human free choice? To approach an answer, Hall traces the emerging conception of free will as "freedom of decision" among Greek authors such as Aristotle, Chrysippus and the Stoics, the Platonists, the Epicureans, and Alexander of Aphrodisias, who, she argues, laid the groundwork for Origen's "innovative narrative understanding of free will" in the context of "epistemological considerations surrounding prophecy" (55–71, 75). These sections of her book present a striking glimpse into early Christian departure from the Greek classical tradition, and her exploration of Origen's defense of both free will and [End Page 294] divine foreknowledge opens the door to further research on his theology of conversion and the relation between grace and nature (75–85, 91).While the entirety of her work is thought-provoking, some elements of Hall's presentation of Origen's theology may be open to a critical response by patristic scholars. Throughout her work, Hall consistently characterizes Origen's spiritual readings of Scripture—and prophecy—in direct opposition to its literal readings. For instance, she writes that, for Origen, just as "some verses do not have a somatic reading and cannot be taken literally," some prophecies are intended to be read as "stumbling blocks or riddles for the exegete to ponder," rather than accurate or "coherent" predictions of the future (193, 53). Additionally, Hall ties Origen's insights on prophecy in the Old Testament to his depiction of Christ as the "ultimate content of... (shrink)

A significant part of Kit Fine’s work in metaphysics assumes a very fine-grained individuation of propositions and facts. This article discusses how such fine distinctions lead to inconsistency in ways which are similar to the inconsistency of naive set comprehension. The case of constraints on individuation arising from a relation of metaphysical ground will be considered in particular. Fine has developed a view of sets in response to the inconsistency of naive set comprehension according to which sets are postulated, and (...) so form a merely potential hierarchy. This article explores what an analogous potentialist response might look like in the case of finely distinguished propositions and facts, and applies the resulting view to the case of metaphysical grounding. A potentially problematic feature of the view is highlighted, which is that it is unclear how it might allow one to formulate in suitable generality the claim that grounding is a well-founded relation among possible propositions.

The author considers ethical obligations in relation to all living beings. As a result, he formulates the guiding principle of our actions - a bioethical imperative «Respect each living being as an end in itself and, if possible, treat it, as yourself». Based on this principle, you can pedagogically influence morality with the help of various scientific disciplines.

The Divine Right of Kings and the Right of Resistance in the Early Middle Ages. Kern demonstrates that the medieval ruler was dependent on God and on the people. Both are under God and under the law. Laws are not made but discovered. In order to be valid, a law does not have to be made by the state, but it has to be old and good. (Kern shows this also in his article 'Recht und Verfassung im Mittelalter'.) Neither the (...) ruler nor the people were 'sovereign' in the modern sense. Thus, 'Gottesgnadentum' (the divine right of kings) does not mean that the ruler can do and rule as he wants. (shrink)

This volume contains invited and contributed papers delivered at a symposium on the occasion of Professor Glauber's 60th birthday. The papers, many of which are authored by world leaders in their fields, contain recent research work in quantum optics, statistical mechanics and high energy physics related to the pioneering work of Professor Roy Glauber; most contain original research material that is previously unpublished. The concepts of coherence, cooperativity and fluctuations in systems with many degrees of freedom are a common base (...) for all of Professor Glauber's research initiatives and, in fact, for much of contemporary physics. His role in shaping these cconcepts is reflected and honoured in the papers contained in this book. (shrink)
