Abstract. Philosophers frequently invoke our ability to imagine, conceive or suppose various thing in order to explain how we achieve our cognitive goals when we make decisions about future actions, when we perform thought experiments, and when we engage in games of pretense. But what is the relationship between imaginings, conceivings, and supposings? And what exactly are the epistemic roles they play in the cognitive projects in which they are involved? This chapter provides answers to these questions by first bringing out a contrast between what we do when we imagine and what we do when we suppose, and then by showing how to fit conceivings into the emerging systematic picture of the ways we use different forms of hypothetical thinking to acquire knowledge.
The Concept of Beastliness: Philosophy, Ethics and Animal Behaviour
Introduction: Every age has its pet contradictions. Thirty years ago, we used to accept Marx and Freud together, and then wonder, like the chameleon on the tartan, why life was so confusing. Today there is similar trouble over the question whether there is, or is not, something called Human Nature. On the one hand, there has been an explosion of animal behaviour studies, and comparisons between animals and men have become immensely popular. People use evidence from animals to decide whether man is naturally aggressive, or naturally territorial; even whether he has an Aggressive or Territorial Instinct. On the other hand, many sociologists and psychologists still seem to hold the Behaviourist view that man is a creature entirely without instincts, and so do existentialist philosophers. If so, all comparison with animals must be irrelevant. On that view, man is entirely the product of his culture. He starts off infinitely plastic, and is formed completely by the society in which he grows up.
Leibniz on Causation, Part 1
Abstract: Leibniz holds that created substances do not causally interact with each other but that there is causal activity within each such creature. Every created substance constantly changes internally, and each of these changes is caused by the substance itself or by its prior states. Leibniz describes this kind of intra-substance causation both in terms of final causation and in terms of efficient causation. How exactly this works, however, is highly controversial. I will identify what I take to be the major interpretive issues surrounding Leibniz’s views on causation and examine several influential interpretations of these views. In ‘Leibniz on Causation – Part 2’ I will then take a closer look at final causation.
Leibniz on Causation, Part 2
Abstract: Leibniz is almost unique among early modern philosophers in giving final causation a central place in his metaphysical system. All changes in created substances, according to Leibniz, have final causes, that is, occur for the sake of some end. There is, however, no consensus among commentators about the details of Leibniz’s views on final causation. The least perfect types of changes that created substances undergo are especially puzzling because those changes seem radically different from paradigmatic instances of final causation. Building on my more general discussion of efficient and final causation in ‘Leibniz on Causation – Part 1,’ I will examine and assess some of the rival interpretations of Leibniz’s account of final causation.
Does Dispositionalism Entail Panpsychism?
Abstract: According to recent arguments for panpsychism, all (or most) physical properties are dispositional, dispositions require categorical grounds, and the only categorical properties we know are phenomenal properties. Therefore, phenomenal properties can be posited as the categorical grounds of all (or most) physical properties—in order to solve the mind–body problem and/or in order avoid noumenalism about the grounds of the physical world. One challenge to this case comes from dispositionalism, which agrees that all physical properties are dispositional, but denies that dispositions require categorical grounds. In this paper, I propose that this challenge can be met by the claim that the only (fundamentally) dispositional properties we know are phenomenal properties, in particular, phenomenal properties associated with agency, intention and/or motivation. Versions of this claim have been common in the history of philosophy, and have also been supported by a number of contemporary dispositionalists (and other realists about causal powers). I will defend a new and updated version of it. Combined with other premises from the original case for panpsychism—which are not affected by the challenge from dispositionalism—it forms an argument that dispositionalism entails panpsychism.
Freedom, Self-Prediction, and the Possibility of Time Travel
Abstract: Do time travellers retain their normal freedom and abilities when they travel back in time? Lewis, Horwich and Sider argue that they do. Time-travelling Tim can kill his young grandfather, his younger self, or whomever else he pleases—and so, it seems can reasonably deliberate about whether to do these things. He might not succeed. But he is still just as free as a non-time traveller. I-ll disagree. The freedom of time travellers is limited by a rational constraint. Tim can-t reasonably deliberate on killing his grandfather, certain that he-ll fail. If Tim follows his evidence, and appropriately self-predicts, he will be certain he won-t kill his grandfather. So if Tim is both evidentially and deliberatively rational, he can-t deliberate on killing his grandfather. This result has consequences. Firstly, it shows how evidential limits in the actual world contribute to our conception of the future as open. Secondly, it undercuts arguments against the possibility of time travel. Thirdly, it affects how we evaluate counterfactuals in time travel worlds, as well as our own. I-ll use the constraint to motivate an evidential and temporally neutral method of evaluating counterfactuals that holds fixed what a relevant deliberating agent has evidence of, independently of her decision. Using this method, an agent-s local abilities may be affected by what happens globally at other times, including the future.
Going Beyond the Fundamental: Feminism in Contemporary Metaphysics
Abstract: Much recent literature in metaphysics attempts to answer the question, ‘What is metaphysics?’ In this paper I argue that many of the most influential contemporary answers to this question yield the result that feminist metaphysics is not metaphysics. I further argue this result is problematic.
Observations upon Experimental Philosophy (1666)
Publisher’s Note: Margaret Cavendish’s 1668 edition of Observations upon Experimental Philosophy, presented here in its first modern edition, holds a unique position in early modern philosophy. Cavendish rejects the Aristotelianism which was taught in the universities in the seventeenth century, and the picture of nature as a grand machine which was propounded by Hobbes, Descartes and members of the Royal Society of London, such as Boyle. She also rejects the views of nature which make reference to immaterial spirits. Instead she develops an original system of organicist materialism, and draws on the doctrines of ancient Stoicism to attack the tenets of seventeenth-century mechanical philosophy. Her treatise is a document of major importance in the history of women’s contributions to philosophy and science.
Causation and Free Will
Publisher’s Note: Carolina Sartorio argues that only the actual causes of our behaviour matter to our freedom. The key, she claims, lies in a correct understanding of the role played by causation in a view of that kind. Causation has some important features that make it a responsibility-grounding relation, and this contributes to the success of the view. Also, when agents act freely, the actual causes are richer than they appear to be at first sight; in particular, they reflect the agents’ sensitivity to reasons, where this includes both the existence of actual reasons and the absence of other reasons. So acting freely requires more causes and quite complex causes, as opposed to fewer causes and simpler causes, and is compatible with those causes being deterministic. The book connects two different debates, the one on causation and the one on the problem of free will, in new and illuminating ways.
Processes, Continuants, and Individuals
Abstract: The paper considers and opposes the view that processes are best thought of as continuants, to be differentiated from events mainly by way of the fact that the latter, but not the former, are entities with temporal parts. The motivation for the investigation, though, is not so much the defeat of what is, in any case, a rather implausible claim, as the vindication of some of the ideas and intuitions that the claim is made in order to defend — and the grounding of those ideas and intuitions in a more plausible metaphysics than is provided by the continuant view. It is argued that in addition to a distinction between events (conceived of as count-quantified) and processes (conceived of as mass-quantified) there is room and need for a third category, that of the individual process, which can be illuminatingly compared with the idea of a substance. Individual processes indeed share important metaphysical features with substantial continuants, but they do not lack temporal parts. Instead, it is argued that individual processes share with substantial continuants an important property I call ‘modal robustness in virtue of form’. The paper explains what this property is, and further suggests that the category of individual process, thus understood, might be of considerable value to the philosophy of action.
