Modality, morality and belief are among the most controversial topics in philosophy today, and few philosophers have shaped these debates as deeply as Ruth Barcan Marcus. Inspired by her work, a distinguished group of philosophers explore these issues, refine and sharpen arguments and develop new positions on such topics as possible worlds, moral dilemmas, essentialism, and the explanation of actions by beliefs. This 'state of the art' collection honours one of the most rigorous and iconoclastic of philosophical pioneers.

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

In order to avoid the problems faced by standard realist analyses of the “relation” of instantiation, Baxter and, following him, Armstrong each analyze the instantiation of a universal by a particular in terms of their partial identity. I introduce two related conceptions of partial identity, one mereological and one non-mereological, both of which require at least one of the relata of the partial identity “relation” to be complex. I then introduce a second non-mereological conception of partial identity, which allows (...) for both relata to be simple. I take these three conceptions to exhaust the plausible ways of construing two entities as being partially identical. I then argue that there is no analysis (including those offered by Baxter and Armstrong) of a universal and a particular as being partially identical consistent with any of these three conceptions that (i) is coherent, (ii) is consistently realist, (iii) does not lead to absurd consequences, and (iv) offers a “solution” to the problem of instantiation that avoids the problems with the other standard realist responses. In so arguing, I offer a criticism of the analysis of instantiation as partial identity that is independent of the standard criticism that it entails the necessity of predication. (shrink)

[Colour is king in our innate quality space, but undistinguished in cosmic circles.] Most philosophers would agree with at least the second half of Quine's dictum. It is indeed on the general view wrong to believe that, as qualities, colours are extra-mentally actual in even the humblest role. Mind-independent material things have on the general view powers to cause sensations of red or blue, but if, in [sensations of red or blue], [red] and [blue] name qualities, we are not to (...) believe that these qualities are possessed by things causing the sensations. My first thesis, defended in section 2, is that partly because we do count colours as eminent among qualities, we would on reflection want it to be true that some things have such qualities when they are not perceived. It would therefore be sad subsequently to discover the wrongness of believing that this is how things are. My second thesis, defended in sections 3 and 4, is that there is in fact no danger as yet of this kind of disappointment. So far, the philosophers have not shown that, if we believe that colour qualities exist as contents of experience, we ought not also to believe that things have these qualities when they are not perceived. One might of course deny that colour qualities exist even as contents of experience, so that the desire for them to be mind-independently exemplified evaporates on the realization that it lacks an intelligible object. Our pre-scientific concept of red, according to Armstrong, is, apart from being the concept of something falling under a determinable, [all blank or gap]. (shrink)

Cassirer’s Die Platonische Renaissance in England und die Schule von Cambridge, of which the present work is a translation, was first published in 1932; it therefore necessarily takes no account of the mass of work on the English Catholic humanists of the Renaissance, beginning with Chambers’s Thomas More, and on 17th-century English religious thought, which has appeared in the last 20 years. This may partly account for the rather old-fashioned impression which the book produces. Cassirer still understood More, Colet, and (...) Erasmus after the manner of Seebohm’s Oxford Reformers, a book which he frequently quotes. But the misunderstanding which, so it seems to the present reviewer, makes the picture given by the book as a whole a distorted one, goes rather deeper. The eminent neo-Kantian author appears to think that authentic Christian orthodoxy is Augustinianism, and Augustinianism interpreted in the manner of Jansenius or Calvin. Hence the philosophy of St. Thomas, to which he gives some fine and understanding pages, appears to him as a heroic but unsuccessful attempt to establish a Christian humanism on an Aristotelian basis which had little lasting effect ; he is led to represent such great and profoundly Catholic figures of the Renaissance as Cardinal Nicholas of Cusa and St. Thomas More as fundamentally unorthodox; in dealing with his main subject, the Cambridge Platonists, he presents ideas which any Catholic brought up in an enlightened Thomist tradition will naturally recognize as a normal part of his own religious and philosophical inheritance as if they were in the deepest disaccord with the teachings of orthodox Christianity; and he greatly exaggerates the opposition between the Cambridge Platonists and their Puritan contemporaries.

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a (...) comprehensive and rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

In his last book, David Armstrong sets out his metaphysical system in a set of concise and lively chapters each dealing with one aspect of the world. He begins with the assumption that all that exists is the physical world of space-time. On this foundation he constructs a coherent metaphysical scheme that gives plausible answers to many of the great problems of metaphysics. He gives accounts of properties, relations, and particulars; laws of nature; modality; abstract objects such as numbers; (...) and time and mind. (shrink)

The Idea of a Moral Economy is the first modern edition and English translation of three questions disputed at the University of Paris in 1330 by the theologian Gerard of Siena. The questions represent the most influential late medieval formulation of the natural law argument against usury and the illicit acquisition of property. Together they offer a particularly clear example of scholastic ideas about the nature and purpose of economic activity and the medieval concept of a moral economy. In his (...) introduction, editor Lawrin Armstrong discusses Gerard's arguments and considers their significance both within the context of scholastic philosophy and law and as a critique of contemporary mainstream economics. His analysis demonstrates how Gerard's work is not only a valuable source for understanding economic thought in pre-modern Europe, but also a fertile resource for scholars of law, economics, and philosophy in medieval Europe and beyond.

The Itinerarium provides a concise introduction to Bonaventure's theological understanding. This new translation presents Latin and English on facing pages, followed by an extensive and detailed commentary on the historical, scriptural, and linguistic contexts of the text and its translation.

An urgent account of the state of our oceans today--and what we must do to protect them The ocean sustains life on our planet, from absorbing carbon to regulating temperatures, and, as we exhaust the resources to be found on land, it is becoming central to the global market. But today we are facing two urgent challenges at sea: massive environmental destruction and spiraling inequality in the ocean economy. Chris Armstrong reveals how existing governing institutions are failing to respond (...) to the most pressing problems of our time, arguing that we must do better. Armstrong examines these crises--from the fate of people whose lands will be submerged by sea level rise to the exploitation of people working in fishing to the rights of marine animals--and makes the case for a powerful World Ocean Authority capable of tackling them. A Blue New Deal presents a radical manifesto for putting equality, democracy, and sustainability at the heart of ocean politics. (shrink)

This paper is an essay in counterfactual epistemology. What if experience have high-level contents, to the effect that something is a lemon or that someone is sad? I survey the consequences for epistemology of such a scenario, and conclude that many of the striking consequences could be reached even if our experiences don't have high-level contents.

Our personal and political worlds are rife with arguments and disagreements, some of them petty and vitriolic. The inability to compromise and understand the opposition is epidemic today, from countries refusing to negotiate, to politicians pandering to their base. Social media has produced a virulent world where extreme positions dominate. There is much demonization of the other side, very little progress is made, and the end result is further widening of positions. How did this happen, and what might be done (...) to address it? Walter Sinnott-Armstrong says there is such a thing as a "good" argument: Reasonable arguments can create more mutual understanding and respect, and even if neither party is convinced by the other, compromise is still possible. Think Again shows the importance of good arguments and reveals common misunderstandings. Rather than a means to persuade other people or beat them in an intellectual competition, Sinnott-Armstrong sees arguments as an essential tool for constructive interaction with others. After showing how the failure of good arguments has led us to society's current woes, he shows readers what makes a good argument. In clear, lively, and practical prose, and with plentiful examples from politics, popular culture, and everyday life, Sinnott-Armstrong explains what defines an argument, identifies the components of good arguments as well as fallacies to avoid, and demonstrates what good arguments can accomplish. Armed with these tools, readers will be able to spot bad reasoning and bad arguments, and to advance their own views in a forceful yet logical way. These skills could even help repair our tattered civic culture. (shrink)

This volume contains a selection of authoritative essays exploring the central questions raised by the conjectured technological singularity. In informed yet jargon-free contributions written by active research scientists, philosophers and sociologists, it goes beyond philosophical discussion to provide a detailed account of the risks that the singularity poses to human society and, perhaps most usefully, the possible actions that society and technologists can take to manage the journey to any singularity in a way that ensures a positive rather than a (...) negative impact on society. The discussions provide perspectives that cover technological, political and business issues. The aim is to bring clarity and rigor to the debate in a way that will inform and stimulate both experts and interested general readers. (shrink)

This work "collects the author's work at the intersection between political philosophy and religion. Alongside his influential earlier essays, it includes nine new essays in which Wolterstorff develops original lines of argument and stakes out novel positions regarding the nature of liberal democracy, human rights, and political authority. Taken together, these positions are an attractive alternative to the so-called public reason liberalism defended by thinkers such as John Rawls"--jacket.

Modern science began as natural philosophy, an admixture of philosophy and science. It was then killed off by Newton, as a result of his claim to have derived his law of gravitation from the phenomena by induction. But this post-Newtonian conception of science, which holds that theories are accepted on the basis of evidence, is untenable, as the long-standing insolubility of the problem of induction indicates. Persistent acceptance of unified theories only in physics, when endless equally empirically successful disunified rivals (...) are available, means that physics makes a persistent, problematic metaphysical assumption about the universe: that all disunified theories are false. This assumption, precisely because it is problematic, needs to be explicitly articulated within physics, so that it can be critically assessed and, we may hope, improved. The outcome is a new conception of science—aim-oriented empiricism—that puts science and philosophy together again, and amounts to a modern version of natural philosophy. Furthermore, aim-oriented empiricism leads to the solution to the problem of induction. Natural philosophy pursued within the methodological framework of aim-oriented empiricism is shown to meet standards of intellectual rigour that science without metaphysics cannot meet. (shrink)

How is consciousness possible? What biological purpose does it serve? And why do we value it so highly? In Soul Dust, the psychologist Nicholas Humphrey, a leading figure in consciousness research, proposes a startling new theory. Consciousness, he argues, is nothing less than a magical-mystery show that we stage for ourselves inside our own heads. This self-made show lights up the world for us and makes us feel special and transcendent. Thus consciousness paves the way for spirituality, and allows (...) us, as human beings, to reap the rewards, and anxieties, of living in what Humphrey calls the "soul niche." Tightly argued, intellectually gripping, and a joy to read, Soul Dust provides answers to the deepest questions. It shows how the problem of consciousness merges with questions that obsess us all--how life should be lived and the fear of death. Resting firmly on neuroscience and evolutionary theory, and drawing a wealth of insights from philosophy and literature..."--Jacket. (shrink)

Centring on human perception, attunement to others, and a transcendent conception of the good, Iris Murdoch's intervention in moral philosophy remains an insightful and evocative source for ethical theory. Discerning some pervasive dualisms that hamper its coherence and development, I suggest that her work finds a generative conversation partner in the contemporary metaphysician, William Desmond. Desmond's thought offers promising avenues to overcome these dualisms by repositioning the source and nature of value and by theorising an anti-reductive, relational ontology. Staging a (...) constructive encounter between these two thinkers that preserves Murdoch's distinct prioritisation of attention and individuality within a Desmond-inspired metaphysics, I present a synthetic ethical approach that promotes the ideal of attending to an other—in the givenness of its particularity, manifold surplus, and constitutive relationality—as good in itself.

Here I show that the one-variable fragment of several first-order relevant logics corresponds to certain S5ish extensions of the underlying propositional relevant logic. In particular, given a fairly standard translation between modal and one-variable languages and a permuting propositional relevant logic L, a formula $$\mathcal {A}$$ A of the one-variable fragment is a theorem of LQ (QL) iff its translation is a theorem of L5 (L.5). The proof is model-theoretic. In one direction, semantics based on the Mares-Goldblatt [15] semantics for (...) quantified L are transformed into ternary (plus two binary) relational semantics for S5-like extensions of L (for a general presentation, see Seki [26, 27]). In the other direction, a valuation is given for the full first-order relevant logic based on L into a model for a suitable S5 extension of L. I also discuss this work’s relation to finding a complete axiomatization of the constant domain, non-general frame ternary relational semantics for which RQ is incomplete [11]. (shrink)

I propose a revision of Cantor’s account of set size that understands comparisons of set size fundamentally in terms of surjections rather than injections. This revised account is equivalent to Cantor's account if the Axiom of Choice is true, but its consequences differ from those of Cantor’s if the Axiom of Choice is false. I argue that the revised account is an intuitive generalization of Cantor’s account, blocks paradoxes—most notably, that a set can be partitioned into a set that is (...) bigger than it—that can arise from Cantor’s account if the Axiom of Choice is false, illuminates the debate over whether the Axiom of Choice is true, is a mathematically fruitful alternative to Cantor’s account, and sheds philosophical light on one of the oldest unsolved problems in set theory.

There is an extensive literature on time travel in both philosophy and physics. Part of the great interest of the topic stems from the fact that reasons have been given both for thinking that time travel is physically possible—and for thinking that it is logically impossible! This entry deals primarily with philosophical issues; issues related to the physics of time travel are covered in the separate entries on time travel and modern physics and time machines. We begin with the definitional (...) question: what is time travel? We then turn to the major objection to the possibility of backwards time travel: the Grandfather paradox. Next, issues concerning causation are discussed—and then, issues in the metaphysics of time and change. We end with a discussion of the question why, if backwards time travel will ever occur, we have not been visited by time travellers from the future. (shrink)

A doctrine of intelligent design through evolution is not going to find many friends. It is destined to encounter opposition on all sides. Among scientists the backlog of evolution will have little patience for intelligent design. Among religiousists, many who form intelligent design have their doubts about evolution. In the general public s mind there is a diametrical opposition between evolution and intelligent design: one excludes the other. This book will argue that this view of the matter is not correct, (...) and that in actuality one can regard evolution itself as a pathway to intelligent design. We would do well to go beyond The Origin of Species and taking as our guide such works as W. Wentworth Thomson s On Growth and Form acknowledging that evolutionary adaptation can result in solutions of a sort that intelligence could readily ratify. Accordingly, what the present book seeks is a naturalization of Intelligent Design that sees such design as itself the result of natural and evolutionary processes.". (shrink)

This chapter provides a classification scheme for artificial intelligence (AI) predictions, and tools for analyzing their reliability and uncertainties. It presents a series of brief case studies of some of the most famous AI predictions: the initial Dartmouth AI conference; Hubert Dreyfus' criticism of AI; Ray Kurzweil's predictions in The Age of Spiritual Machines; and Stephen Omohundro's AI Drives. The chapter takes every falsifiable statement about future AI to be a prediction. Thus the following four categories are all predictions: Timelines (...) and outcome predictions, Scenarios, Plans, and Issues and metastatements. The following schema was suggested by a review of the AI predictions literature : Causal models, Non‐causal models, The outside view, Philosophical arguments, and Expert judgment. The chapter looks at four prominent AI predictions, and analyses their accuracy, attempting to gain insights that will be useful for assessing future prediction. (shrink)

Pragmatic processes crucially rely on background or contextual information supplied by the hearer, which may significantly affect the outcome of the comprehension process. Construed as a branch of cognitive psychology, pragmatics is the study of the cognitive systems apart from the I‐language and the parser which enable speaker and hearer (or communicator and audience) to co‐ordinate on the intended interpretation, and this is how we propose to treat it here. This chapter considers some of Noam Chomsky's suggestions about how the (...) cognitive systems underlying human abilities might be investigated. It discusses his reasons and consider how far this skepticism may be due to his particular conception of pragmatics. The chapter outlines an approach to pragmatics that seems to be compatible with his general methodology and is based on an alternative conception of pragmatics that we sketch out. (shrink)

The aim of the Schematism chapter of the Critique of Pure Reason is to solve the problem posed by the “inhomogeneity” of intuitions and categories: the sensible properties of objects represented in intuition are of a different kind than the properties represented by categories. Kant's solution is to introduce what he calls “transcendental schemata,” which mediate the subsumption of objects under categories. I reconstruct Kant's solution in terms of two substantive premises, which I call Subsumption Sufficiency (i.e., that subsuming an (...) object under a transcendental schema is sufficient to subsume it under the corresponding category) and Real Possibility (i.e., that it is really possible to subsume objects under each of the transcendental schemata). These two principles, together with a trivial modal one (the Subsumption-Possibility Link), entail that it is possible to subsume objects under categories; in other words, the argument of the Schematism is valid. The main work of the paper consists in reconstructing Kant's arguments for, and explanations of, these premises. I argue that they hinge on Kant's claim that transcendental schemata are “time-determinations,” which I interpret to mean: rules for reflexively representing the temporal relations among our own representational states. On the basis of this reading, I reconstruct Kant's argument for Subsumption Sufficiency, category by category. I also explain why Real Possibility follows almost immediately. Granting Kant the argument up to this point in the Critique, the argument of the Schematism is sound. (shrink)
