In “Bioethicists Today: Results of the Views in Bioethics Survey,” Pierson et al. (2024) provide a valuable snapshot of the normative commitments and demographic backgrounds of 824 U.S. bioethicist...

Brian Leftow offers a theist theory of necessity and possibility, and a new sort of argument for God's existence. He argues that necessities of logic and mathematics are determined by God's nature, but that it is events in God's mind - his imagination and choice - that account for necessary truths about concrete creatures.

"Anselm of Canterbury gave the first modal "ontological" argument for God's existence. Yet, despite its distinct originality, philosophers have mostly avoided the question of what modal concepts the argument uses, and whether Anselm's metaphysics entitles him to use them. Here, Brian Leftow sets out Anselm's modal metaphysics. He argues that Anselm has an "absolute", "broadly logical", or "metaphysical" modal concept, and that his metaphysics provides acceptable truth makers for claims in this modality. He shows that his modal argument (...) is committed to the Brouwer system of modal logic, and defends the claim that Brouwer is part of the logic of "absolute" or "metaphysical" modality. He also defends Anselm's premise that God would exist with absolute necessity against all extant objections, providing new arguments in support of it and ultimately defending all but one premise of Anselm's best argument for God's existence"--.

This article provides an explanation of Anselm’s understanding of necessity. Anselm did not write much about modality, and what he did write is puzzling. The dominant readings of Anselm see him as having two concepts of necessity, one merely physical or causal, the other logical or “alethic.” This article argues that Anselm has just one concept of necessity, which corresponds best to what is now called broadly logical or absolute necessity, but whose metaphysics is in terms of powers and lacks (...) of power. The rival interpretations of A. D. Smith, Thomas Williams, and Sandra Visser are discussed and criticized in detail. (shrink)

[I] Introduction The Western religions all claim that God is eternal. This claim finds strong expression in the Old Testament, which is common property of ...

Before Duns Scotus, most philosophers agreed that God is identical with His necessary intrinsic attributes--omnipotence, omniscience, etc. This Identity Thesis was a component of widely held doctrines of divine simplicity, which stated that God exemplifies no metaphysical distinctions, including that between subject and attribute. The Identity Thesis seems to render God an attribute, an abstract object. This paper shows that the Identity Thesis follows from a basic theistic belief and does not render God abstract. If also discusses how one might (...) move from the Identity Thesis to the full doctrine of divine simplicity and shows that the Identity Thesis generates a new ontological argument. (shrink)

Western theism holds that God cannot do evil. Christians also hold that Christ is God the Son and that Christ was tempted to do evil. These claims appear to be jointly inconsistent. I argue that they are not.

Latin models of the Trinity begin from the existence of one God, and try to explain how one God can be three Persons. I offer an account of this based on an analogy with time-travel. A time-traveler returning to the same point in time repeatedly might have three successive events in his/her life occurring at that one location in public time. So too, God’s life might be such that three distinct parts of His life are always occurring at once, though (...) without any succession between them, and this might give God the triune structure Christian theology believes He has. (shrink)

This chapter presents and critically discusses the main historical variants of the “ontological argument,” a form of a priori argument for the existence of God pioneered by Anselm of Canterbury. I assess the contributions of Anselm, Descartes, Leibniz, and Gödel, and criticisms by Gaunilo, Kant, and Oppy among others.

Anselm of Canterbury (1033-1109), Benedictine monk and the second Norman archbishop of Canterbury, is regarded as one of the most important philosophers and theologians of the Middle Ages. The essays in this volume explore all of his major ideas both philosophical and theological, including his teachings on faith and reason, God's existence and nature, logic, freedom, truth, ethics, and key Christian doctrines. There is also discussion of his life, the sources of his thought, and his influence on other thinkers. New (...) readers will find this the most convenient, accessible guide to Anselm currently available. Advanced students and specialists will find a conspectus of recent developments in the interpretation of Anselm. (shrink)

William Hasker has rejected my rejection of his criticisms of my “Latin” account of the Trinity. I now reject his rejection.

After defining presentism, I consider four arguments that presentism and divine atemporality are incompatible. I identify an assumption common to the four, ask what reason there is to consider it true, and argue against it.

Richard Brian Davis offers several criticisms of a semantics I once proposed for subjunctive conditionals with impossible antecedents. I reply to these.

The claim that God is eternal is a standard feature of late–classical and mediaeval philosophical theology. It is prominent in discussions of the relation of God's foreknowledge to human freedom, and its consequences pervade traditional accounts of other kinds of divine knowledge, of God's will, and of God's relation to the world. So an examination of the concept of eternity promises to repay our efforts with a better understanding of the history of philosophical theology and with insight into the concept (...) of God. Eleonore Stump and Norman Kretzmann's ‘Eternity’ is a forceful, sophisticated presentation and defence of the notion of eternity. Our treatment of eternity will focus on two of Stump and Kretzmann's claims. First, Stump and Kretzmann contend that eternity isa kind of ‘atemporal duration’. We will see that while this is true, it is only part of the story. Second, Stump and Kretzmann claim to provide a viable account of how the existence of an eternal being can be simultaneous with some temporal event. We will see that and why they have not done so.

Augustine, Aquinas and many other medievals held the doctrine of divine simplicity (DDS) -that God has no parts of any sort. Augustine took this to imply that for any non-relational attribute F, if God is F, God = Fness. This can seem to create three problems. I set them out. Having done so, I show that Augustine's DDS is set within a view of attributes now unfamiliar to us. When we bring this into the picture, it turns out that two (...) of the problems do not really arise and the third is not really problematic. I then suggest that my rescue of Augustine may rescue other prominent friends of DDS as well. (shrink)

This paper examines Anselm’s reply to this argument in order to shed light on a number of issues in philosophical theology, including the metaphysics of the Incarnation, the relation between perfect being theology and the doctrines of the Incarnation and the Atonement, the senses in which the Christian God might be impassible, and the nature of God’s perfect rationality and wisdom. (edited).

Most analytic philosophers hold that if God exists, He exists with broad logical necessity. Richard Swinburne denies the distinction between narrow and broad logical necessity, and argues that if God exists, His existence is narrow-logically contingent. A defender of divine broad logical necessity could grant the latter claim. I argue, however, that not only is God's existence broad-logically necessary, but on a certain understanding of God's relation to modality, it comes out narrow-logically necessary. This piece argues against Swinburne's overall account (...) of modality and rebuts his argument for narrow-logical contingency. (shrink)

William Hasker replies to my arguments against social Trinitarianism, offers some criticism of my own view, and begins a sketch of another account of the Trinity. I reply with some defence of my own theory and some questions about his.

Philosophers have argued that stakes affect knowledge: a given amount of evidence may suffice for knowledge if the stakes are low, but not if the stakes are high. By contrast, empirical work on the influence of stakes on ordinary knowledge ascriptions has been divided along methodological lines: “evidence‐fixed” prompts rarely find stakes effects, while “evidence‐seeking” prompts consistently find them. We present a cross‐cultural study using both evidence‐fixed and evidence‐seeking prompts with a diverse sample of 17 populations in 11 countries, speaking (...) 14 languages. Our study is the first to use an evidence‐seeking prompt cross‐culturally, and includes several previously untested populations (including indigenous populations). Across cultures, we do not find evidence of a stakes effect with our evidence‐fixed prompt, but do with our evidence‐seeking prompt. We argue that the divergent results reveal a tension within folk epistemology: people's beliefs about when it is appropriate to ascribe knowledge differ significantly from their actual practice in ascribing knowledge.

I rebut four claims made in a recent article by Katherin Rogers. En route I discuss how a timeless God might perceive all of “tensed” time at once.

I explain the doctrine of divine simplicity, and reject what is now the standard way to explicate it in analytic philosophy. I show that divine simplicity imperils the claim that God is free, and argue against a popular proposal for dealing with the problem.

Anselm is commonly credited with two a priori arguments for God's existence, the non-modal argument of Proslogion 2 and a modal argument some find in Proslogion 3. But his Reply to Gaunilo contains a third. The argument as Anselm gives it has flaws, but they are not fatal, and its main premise can serve as the basis of a simpler, stronger argument.

I display the historical roots of perfect being theology in Greco-Roman philosophy, and the distinctive reasons for Christians to take up a version of this project. I also rebut a recent argument that perfect-being reasoning should lead one to atheism.
