The transformative power of artificial intelligence (AI) is coming to philosophy—the only question is the degree to which philosophers will harness it. In this paper, we argue that the application of AI tools to philosophy could have an impact on the field comparable to the advent of writing, and that it is likely that philosophical progress will significantly increase as a consequence of AI. The role of philosophers in this story is not merely to use AI but also to help (...) develop it and theorize about it. In fact, we argue that philosophers have a prima facie obligation to spend significant effort in doing so, at least insofar as they should spend effort philosophizing. (shrink)

What can we know? How should we live? What is there? Philosophers famously diverge in the answers they give to these and other philosophical questions. It is widely presumed that a lack of convergence on these questions suggests that philosophy is not progressing at all, is not progressing fast enough, or is not progressing as fast as other disciplines, such as the natural sciences. Call the view that ideal philosophical progress is marked by at least some degree of convergence on (...) the core philosophical questions the pro-convergence thesis. I will argue that there is reason to reject the pro-convergence thesis in favor of the anti-convergence thesis, the view that significant viewpoint convergence is at odds with the aims of a philosophically ideal community. The argument centers on a thought experiment about two different philosophical communities. (shrink)

Mary Shepherd (1777–1847) was a fierce and brilliant critic of Berkeley and Hume, who moreover offered strikingly original positive views about the nature of reality and our access to it which deserve much more attention (and credit, since she anticipates many prominent views) than they have received thus far. By way of illustration, I focus on Shepherd's 1824 Essay Upon the Relation of Cause and Effect, Controverting the Doctrine of Mr. Hume, Concerning the Nature of that Relation (ERCE). After a (...) brief setup, I canvas certain of her trenchant objections to Hume’s argumentation; I then present the positive core of her response to Hume, which consists in providing novel accounts of how reason alone or reason coupled with experience can justify, first, that every effect must have a cause, and second, that it is necessary that like causes produce like effects. Among other contributions here, Shepherd provides a distinctively metaphysical argument for the claim that nothing can begin to exist 'of itself' (going beyond an appeal to the Principle of Sufficient Reason, in particular), and leverages difference-making considerations to make the case that a single 'experimentum crucis' can justify causal belief (anticipating Mill's 'method of difference'). I close by highlighting salient features of Shepherd's metaphysics of causation, whereby causation is singularist and local (anticipating Ducasse and Anscombe) and involves synchronic interactions (anticipating Mill's and certain contemporary accounts), and according to which objects are essentially characterized by their causes and effects (anticipating contemporary causal or dispositional essentialist positions).

Is the world internally connected by a web of necessary connections or is everything loose and independent? Followers of David Hume accept the latter by upholding Hume’s Dictum, according to which there are no necessary connections between distinct existences. Roughly put, anything can coexist with anything else, and anything can fail to coexist with anything else. Hume put it like this: “There is no object which implies the existence of any other if we consider these objects in themselves.” Since Hume’s (...) day, Hume’s Dictum has played a major role in philosophy, especially in contemporary metaphysics. In ruling out necessary connections, Hume’s Dictum implies that causal relations and the laws of nature are contingent. It makes other demands on our metaphysics of science as well; for example, it places restrictions on our metaphysics of counterfactuals, dispositions, and explanation. The principle has applications in other areas too. Hume’s Dictum places constraints on our theories of abstract objects and moral properties. For example, Hume’s Dictum rules out the view that moral properties are distinct from, but necessarily connected to, non-moral properties. While Hume’s Dictum is a prominent principle in metaphysics, few Humeans have defended the principle at length. It is assumed more often than it is argued for. As a result, Hume’s Dictum no longer enjoys the reputation it once did. It’s common to hear complaints about the lack of arguments in support of Hume’s Dictum. Moreover, philosophers are increasingly willing to defend views that are at odds with Hume’s Dictum. A striking example of this is the recent explosion of interest in views that take causal relations and the laws of nature to be necessary. Humeans can no longer afford to be complacent. An extended defense of Hume’s Dictum is called for, and that’s what this dissertation aims to offer. This dissertation has three parts. In the first part, I lay out some preliminaries and offer a precise formulation of Hume’s Dictum. In the second part, I develop three arguments in favor of Hume’s Dictum. In the final part, I defend Hume’s Dictum against objections. (shrink)

Novelty—the value of saying something new—appears to be a good-making feature of a philosophical contribution. Beyond this, however, novelty functions as a metric of success. This paper challenges the presumption and expectation that a successful philosophical contribution will be a novel one. As I show, the pursuit of novelty is neither as desirable nor as feasible as it might initially seem.

In recent years, there has been increasing discussion of whether philosophy actually makes progress. This discussion has been prompted, in no small part, by the depth and persistence of disagreement among philosophers on virtually every major theoretical issue in the field. In this paper, I examine the role that the Method of Cases – the widespread philosophical method of testing and revising theories by comparing their verdicts against our intuitions in particular cases – plays in creating and sustaining theoretical disagreements (...) in philosophy. Drawing on work from cognitive psychology, I argue that there is a fundamental incompatibility between the structure of the theories that philosophers seek to construct using the MoC and the structure of the concepts on which our case-specific intuitions are based. This incompatibility renders MoC-based philosophical theorizing unable ever to succeed by the very standards of adequacy that it sets for itself. And this, in turn, helps to explain the depth and persistence of theoretical disagreements – and, in certain ways, the lack of progress – in the many areas of philosophy where the MoC plays an important role.
