George Berkeley notoriously claimed that his immaterialist metaphysics was not only consistent with common sense but that it was also integral to its defense. Roberts argues that understanding the basic connection between Berkeley's philosophy and common sense requires that we develop a better understanding of the four principle components of Berkeley's positive metaphysics: The nature of being, the divine language thesis, the active/passive distinction, and the nature of spirits. Roberts begins by focusing on Berkeley's view of the nature of being. (...) He elucidates Berkeley's view on Locke and the Cartesians and by examining Berkeley's views about related concepts such as unity and simplicity. From there he moves on to Berkeley's philosophy of language arguing that scrutiny of the famous "Introduction" to the Principles of Human Knowledge reveals that Berkeley identified the ideational theory of meaning and understanding as the root cause of some of the worst of man's intellectual errors, not "abstract ideas." Abstract ideas are, rather, the most debilitating symptom of this underlying ailment. In place of the ideational theory, Berkeley defends a rudimentary "use theory" of meaning. This understanding of Berkeley's approach to semantics is then applied to the divine language thesis and is shown to have important consequences for Berkeley's pragmatic approach to the ontology of natural objects and for his approach to our knowledge of, and relation to other minds, including God's. Turning next to Berkeley's much aligned account of spirits, the author defends the coherence of Berkeley's view of spirits by way of providing an interpretation of the active/passive distinction as marking a normative distinction and by focusing on the role that divine language plays in letting Berkeley identify the soul with the will. With these four principles of Berkeley's philosophy in hand, he then returns to the topic of common sense and offers a defense of Berkeley's philosophy as built upon and expressive of the deepest metaphysical commitments of mainstream Christianity. Roberts' reappraisal of this important figure should appeal to all historians of philosophy as well as scholars in metaphysics and philosophy of language. (shrink)

Memory representation for time was studied in two settings. First, an analysis of timing in a laboratory analog of a foraging situation revealed that departure times from a patchy resource followed a Weber Law-like property implied by scalar timing. A trial-by-trial analysis was then pursued in a similar but more structured experimental paradigm, the Peak procedure. Study of covariance structures in the data implicated scalar variance in the memory for time as well as in the decision process, but the correlation (...) pattern ruled out multiple access to memory within a trial.

Summary The Copernican system was condemned as heretical by a decree of the Roman Inquisition in 1633. This decree was effectively, though not officially, withdrawn in 1757, after which date Catholic astronomers felt themselves free to accept and propagate the system without reserve. Between these dates their attitudes varied greatly. In France the decree was never promulgated and was legally unenforceable. Astronomers could be Copernican without any fear of consequences and most of them were, though some, out of respect for (...) the Church, refrained from declaring themselves publicly. In Italy the possible risks were greater, but a few Copernican or near-Copernican works were published without hostile reactions. The ecclesiastical authorities were tolerant and made little positive effort to enforce conformity. By 1744, the system was being freely propagated in Rome itself. (shrink)

There is a problem regarding God and perception right at the heart of Berkeley ’s metaphysics. With respect to this problem, I will argue for : It is intractable. Berkeley has no solution to this problem, and neither can we hope to offer one on his behalf. However, I will also argue for : The truth of need not be seen as threatening the viability of Berkeley ’s metaphysics. In fact, it may even be seen as speaking in its favor.

Is the fact that our universe contains fine-tuned life evidence that we live in a multiverse? Ian Hacking and Roger White influentially argue that it is not. We approach this question through a systematic framework for self-locating epistemology. As it turns out, leading approaches to self-locating evidence agree that the fact that our own universe contains fine-tuned life indeed confirms the existence of a multiverse. This convergence is no accident: we present two theorems showing that, in this setting, any updating (...) rule that satisfies a few reasonable conditions will have the same feature. The conclusion that fine-tuned life provides evidence for a multiverse is hard to escape. (shrink)

This essay offers a defense of Axiarchism's answer to the question, "Why does the world exit?" against prominent objections leveled against it by Derek Parfit. Parfit rejects the Axiarchist answer while abstracting from it his own Selector strategy. I argue that the abstraction fails, and that even if we were to regard Axiarchism as an instance of a Selector hypothesis, we should regard it as the only viable one. I also argue that Parfit's abstraction leads him to mistake the nature (...) and, thereby, the force of Axiarchism's claim to being an ultimate explanation. Finally, I defend the Axiarchist's claim that the good could not fail to rule. (shrink)

I present a dilemma which depressive behavioral pathology poses for both Humean and non-Humean theories of motivation and value. Although the dilemma shows that neither theory can be considered adequate in its standard form, I argue that if the Humean theory is modified so as to embrace a richer notion of satisfaction than it currently does, it can solve the problem which depression poses for it and, thus, the dilemma can be avoided. Embracing a richer notion of satisfaction not only (...) solves this problem, it also extends the scope of the Humean theory in a potentially dramatic way, by extending the explanatory reach of moral psychology to issues often thought to fall outside its scope, namely, issues in moral psychopathology.

The excellent quality and depth of the various essays make [the book] an invaluable resource....It is likely to become essential reading in its field.—CHOICE.

This essay consists of two parts. Part I offers an explanation of Berkeley's understanding of the relationship between materialism and evil. Berkeley regards materialism as the chief instrumental cause of evil in the world. It is the belief in matter that encourages us to believe that God is not immediately, intimately present in every aspect of our life. Immaterialism, by contrast, makes God's immediate presence vivid and thereby serves to undermine the motivation to vice. Part II locates Berkeley's view on (...) matter and evil within the Christian Neoplatonic tradition. I compare Plotinus' minimalist approach to matter and his identification of matter with evil to Berkeley's eliminitivism about matter and his corresponding identification of materialism as the chief source of evil.

Draft version of essay. ABSTRACT: Benjamin Whichcote developed a distinctive account of human nature centered on our moral psychology. He believed that this view of human nature, which forms the foundation of “Cambridge Platonism,” showed that the demands of reason and faith are not merely compatible but dynamically supportive of one another. I develop an interpretation of this oft-neglected and widely misunderstood account of human nature and defend its viability against a key objection.

Draft. Berkeley denied the existence of abstract ideas and any faculty of abstraction. At the same time, however, he embraced innate ideas and a faculty of pure intellect. This paper attempts to reconcile the tension between these commitments by offering an interpretation of Berkeley's Platonism.

This dissertation defends Berkeley's spirit-based Idealism by way of providing an interpretation of the fundamental distinction of his metaphysics, the "active/passive" distinction. I argue that Berkeley developed a distinctively normative reading of "activity" and "passivity" during the exploration of the limits of Lockean-style empiricism recorded in his preparatory notebooks, the Philosophical Commentaries, limits that became especially apparent in connection with the notion of the self or "spirit". After considering and rejecting a proto-Humean "bundle theory" of the self, Berkeley formulated the (...) irreducibly normative conception of "spirit" characteristic of all his published works. In Berkeley's hands, 'spirit' is what Locke would have called a "forensic term, appropriating actions and their merit." The active/passive distinction consequently concerns one's responsibility for something: If a spirit is "active" with respect to X, then X is dependent upon that spirit's will, and, correlatively, it is responsible, answerable, or accountable for X. If a spirit is "passive" with respect to X, then it is not responsible for X. Since Berkeley's idealism is notoriously a spirit-based ontology, the consequences of these understandings were sweeping and dramatic. In the balance of the dissertation I pursue the implications of this interpretation with respect to Berkeley's view of semantics, ontological commitment, knowledge of other minds, and freedom and determinism.

Famous results by David Lewis show that plausible-sounding constraints on the probabilities of conditionals or evaluative claims lead to unacceptable results, by standard probabilistic reasoning. Existing presentations of these results rely on stronger assumptions than they really need. When we strip these arguments down to a minimal core, we can see both how certain replies miss the mark, and also how to devise parallel arguments for other domains, including epistemic “might,” probability claims, claims about comparative value, and so on. A (...) popular reply to Lewis's results is to claim that conditional claims, or claims about subjective value, lack truth conditions. For this strategy to have a chance of success, it needs to give up basic structural principles about how epistemic states can be updated—in a way that is strikingly parallel to the commitments of the project of dynamic semantics.

How should a group with different opinions (but the same values) make decisions? In a Bayesian setting, the natural question is how to aggregate credences: how to use a single credence function to naturally represent a collection of different credence functions. An extension of the standard Dutch-book arguments that apply to individual decision-makers recommends that group credences should be updated by conditionalization. This imposes a constraint on what aggregation rules can be like. Taking conditionalization as a basic constraint, we gather (...) lessons from the established work on credence aggregation, and extend this work with two new impossibility results. We then explore contrasting features of two kinds of rules that satisfy the constraints we articulate: one kind uses fixed prior credences, and the other uses geometric averaging, as opposed to arithmetic averaging. We also prove a new characterisation result for geometric averaging. Finally we consider applications to neighboring philosophical issues, including the epistemology of disagreement. (shrink)

This paper focuses on four passages in the journey of the universe from beginning to end: its origin in the Big Bang, the production of heavy elements in first generation stars, the buzzing symphony of life on earth, and the distant future of the cosmos. As a physicist and a Christian theologian, I will ask how each of these passages casts light on the deepest questions of existence and our relation to God, and in turn how these questions are being (...) explored through ongoing research into the interaction between Christian theology and the natural sciences.

“There are no gaps in logical space,” David Lewis writes, giving voice to sentiment shared by many philosophers. But different natural ways of trying to make this sentiment precise turn out to conflict with one another. One is a *pattern* idea: “Any pattern of instantiation is metaphysically possible.” Another is a *cut and paste* idea: “For any objects in any worlds, there exists a world that contains any number of duplicates of all of those objects.” We use resources from model (...) theory to show the inconsistency of certain packages of combinatorial principles and the consistency of others.

Is it harder to acquire knowledge about things that really matter to us than it is to acquire knowledge about things we don't much care about? Jason Stanley 2005 argues that whether or not the relational predicate 'knows that' holds between an agent and a proposition can depend on the practical interests of the agent: the more it matters to a person whether p is the case, the more justification is required before she counts as knowing that p. The evidence (...) for Stanley's thesis includes a number of intuitive judgments about examples. In this paper we provide parallel examples for which Stanley's thesis requires unwelcome knowledge-attributions, and argue that this is possible because his thesis conflicts with familiar and plausible principles about knowledge.

I gratefully acknowledge and respond here to four reviews of my recent book, Cosmology from Alpha to Omega. Nancey Murphy stresses the importance of showing consistency between Christian theology and natural science through a detailed examination of my recent model of their creative interaction. She suggests how this model can be enhanced by adopting Alasdair MacIntyre's understanding of tradition in order to adjudicate between competing ways of incorporating science into a wider worldview. She urges the inclusion of ethics in my (...) model and predicts that this would successfully challenge the competing naturalist tradition in contemporary society. John F. Haught weighs the alternatives of viewing divine action as objective versus subjective and of divine action at one level in nature or at all levels. He asks whether physics is fundamental to nature, arguing instead that metaphysics should be considered as fundamental. Michael Ruse assesses occasional versus universal divine action, the problems raised to divine action when it is related to quantum mechanics, and the way these relations exacerbate the challenge of natural theodicy. As an alternative he suggests viewing God as outside time and acting through unbroken natural law. Willem B. Drees discusses my use of the bridge metaphor for the relation between theology and science, the implications when science is inspired by theology, the role of contingency and necessity in the anthropic principle/many-worlds debate, and the challenge of cosmology to eschatology with the ensuing problem of theodicy.

Japanese constructions of whiteness have been shaped by mainstream media and popular culture, which both reproduces and localizes the western discourse of whiteness. At the same time, the growth of the internet, social media, and online culture have exposed Japan to contentious debates in the United States (and elsewhere) concerning racial representation, race-switching, and diversity, as well as providing a platform for Japanese to reexamine contemporary Japanese racial attitudes. This chapter explores the impact that the discourse of representation and diversity (...) in the United States, the Black Lives Matter (BLM) movement, and demographic changes, particularly the growth of diasporic African communities in Japan since the 1980s, have had on Japanese perceptions of “whiteness,” “blackness,” and “Japaneseness.”.

Christopher Southgate offers a remarkable evolutionary theodicy that includes six affirmations and arguments; together they form a unique and very persuasive proposal which he terms a “compound evolutionary theodicy.” Here I summarize the arguments and offer critical reflections on them for further development, with an emphasis on the ambiguity in the goodness of creation; the role of thermodynamics in evolutionary biology; the challenge of horrendous evil in nature; and the theological response to theodicy in terms of eschatology, with its own (...) severe challenge from cosmology.

This paper explores a possible relationship between entropy and evil in terms of metaphor. After presenting the various meanings of entropy in classical thermodynamics and statical mechanics, and the Augustinian and Irenaean theodicies, several similarities and dissimilarities between entropy and evil are described. Underlying the concepts of evil and entropy is the assumption that time has a direction. After examining the scientific basis for this assumption, it is hypothesized that, if evil is real in nature, entropy is what one would (...) expect to find at the level of physical processes, and conversely that, if entropy is coupled to a physical arrow of time, one could expect to find dissipative yet catalytic processes in history and religious experience.
