This paper presents the view that tropes can change, and so are not individuated by their determinate qualitative characters. On the view I have in mind, a trope is at any given time fully determinate, but can change qualitatively within the bounds set by a determinable essence. A charge trope, for example, must at any time have some exact intensity, but can survive changes in intensity. My argument, roughly, is this: Objects can change, and tropes are the parts of objects (...) that change (in a special sense of ‘part’), so tropes can change too. After some preliminaries, I present the argument carefully and discuss the operant notions. I then discuss each premise in turn. I respond to the charge that the view isn't realist, and to objections based on identity‐conditions for tropes. I describe both substratum‐ and bundle‐theoretic versions of the view, and finally, show what the view buys us. (shrink)

We develop a new version of the causal theory of spacetime. Whereas traditional versions of the theory seek to identify spatiotemporal relations with causal relations, the version we develop takes causal relations to be the grounds for spatiotemporal relations. Causation is thus distinct from, and more basic than, spacetime. We argue that this non-identity theory, suitably developed, avoids the challenges facing the traditional identity theory.

It is natural to think that rationality imposes some relationship between what a person believes, and what she believes about what she’s rational to believe. Epistemic akrasia—for example, believing P while believing that P is not rational to believe in your situation—is often seen as intrinsically irrational. This paper argues otherwise. In certain cases, akrasia is intuitively rational. Understanding why akratic beliefs in those case are indeed rational provides a deeper explanation how typical akratic beliefs are irrational—an explanation that does (...) not flow from akrasia per se. This understanding also allows us to diagnose where general anti-akratic arguments go wrong. We can then see why even principles designed to allow only moderate akrasia fail, and also why recognizing the possibility of rational akratic beliefs does not call for finding some other epistemic defect in agents who believe akratically. Believing akratically, in itself, is nothing to apologize for. (shrink)

The problem of probabilities of conditionals is one of the long-standing puzzles in philosophy of language. We defend and update Adams' solution to the puzzle: the probability of an epistemic conditional is not the probability of a proposition, but a probability under a supposition. -/- Close inspection of how a triviality result unfolds in a concrete scenario does not provide counterexamples to the view that probabilities of conditionals are conditional probabilities: instead, it supports the conclusion that probabilities of conditionals violate (...) standard probability theory. -/- This does not call into question probability theory per se; rather, it calls for a more careful understanding of its role: probability theory is a theory of probabilities of propositions; but as conditionals do not express propositions, their probabilities are not subject to the standard laws. -/- We argue that both conditional probabilities and probabilities of conditionals are best understood in terms of the dynamics of supposing, modeled as a restriction operation on a probability space. This version of the suppositionalist view allows us to connect Adams' Thesis to the widely held restrictor view of the semantics of conditionals. -/- We address two common objections to Adams' view: that the relevant probabilities are ‘probabilities only in name’, and that giving up conditional propositions puts us at a disadvantage when it comes to interpreting compounds. -/- Finally, we argue that some putative counterexamples to Adams' Thesis can be diagnosed as fallacies of probabilistic reasoning: they arise from applying to conditionals laws of standard probability theory which are invalid for them.

My topic is how to make decisions when you possess foreknowledge of the consequences of your choice. Many have thought that these kinds of decisions pose a distinctive and novel problem for causal decision theory (CDT). My thesis is that foreknowledge poses no new problems for CDT. Some of the purported problems are not problems. Others are problems, but they are not problems for CDT. Rather, they are problems for our theories of subjunctive supposition. Others are problems, but they are (...) not new problems. They are old problems transposed into a new key. Nonetheless, decisions made with foreknowledge illustrate important lessons about the instrumental value of our choices. Once we've appreciated these lessons, we are left with a version of CDT which faces no novel threats from foreknowledge. (shrink)

(Open Access.) Quantifiers frequently figure in works of fiction. But occurrences of quantificational expressions within fictions seem no more inevitably to be associated with real domains than uses of names within fictions seem inevitably to be associated with existing referents. The paper outlines some philosophical puzzles resulting from this apparent lack of associated domains, puzzles that are broadly analogous to more familiar ones raised by the apparently nonreferential nature of many fictional names. The paper argues, in the light of an (...) important disanalogy between quantifiers and names, that the quantificational puzzles are substantive, in that they cannot be resolved merely by appealing to the possibility of empty domains. It then argues that, despite the cited parallels between occurrences of quantifiers and names within fictions, promising treatments of fictional names do not always straightforwardly generalise to provide accounts of the quantificational phenomena: the quantificational puzzles are therefore not only substantive but also distinctive. The paper provides further testament to the depth and interest of the problems involving content that are generated by fiction, by identifying a very wide range of previously neglected cases, while also helping to situate within a broader context the notoriously hard philosophical challenges posed by fictional names.

Some actions we perform “just like that” without taking a means, e.g., raising your arm or wiggling your finger. Other actions—the nonbasic actions—we perform by taking a means, e.g., voting by raising your arm or illuminating a room by flipping a switch. A nearly ubiquitous view about nonbasic action is that one's means to a nonbasic action constitutes the nonbasic action, as raising your arm constitutes voting or flipping a switch constitutes illuminating a room. In this paper, I challenge this (...) view. I argue that one's means to a nonbasic action can cause rather than constitute it. In the process, we gain a clearer understanding of the scope of our agency—one that includes mental actions such as judgment and decision—and the pluralistic nature of basic features of action including control, purposefulness, and agent participation.

In this paper I will introduce a new compatibilist account of free action: indirect conscious control compatibilism, or just indirect compatibilism for short. On this account, actions are free either when they are caused by compatibilist‐friendly conscious psychological processes, or else by sub‐personal level processes influenced in particular ways by compatibilist‐friendly conscious psychological processes. This view is motivated by a problem faced by a certain family of compatibilist views, which I call conscious control views. These views hold that we act (...) freely when we act in a way that is caused by certain conscious psychological processes. One problem for such views is that current neuroscience suggests that most of our actions are not caused by such processes. Instead, many of the actions we typically suppose are free are caused by sub‐personal level processes and hence would count as not free according to contemporary conscious control views. I argue, contra these views, that many actions caused by these sub‐personal level processes are indirectly free. Further, most of the actions we ordinarily judge to be free are free in this indirect manner. (shrink)

Shared agency is a distinctive kind of sociality that involves interdependent planning, practical reasoning, and action between participants. Philosophical reflection suggests that agents engage in this form of sociality when a special structure of interrelated psychological attitudes exists between them, a set of attitudes that constitutes a collective intention. I defend a new way to understand collective intention as a combination of individual conditional intentions. Revising an initial statement of the conditional intention account in response to several challenges leads to (...) a specification of the properties these intentions need to have in order to be genuine commitments. I then show how a structure of conditional intentions with these properties settles a collection of agents on engaging in social interactions that display all the features typically associated with shared agency.

Traditionally epistemologists have taken doxastic states to come in three varieties—belief, disbelief, and suspension. Recently many epistemologists have taken our doxastic condition to be usefully represented by credences—quantified degrees of belief. Moreover, some have thought that this new credal picture is sufficient to account for everything we want to explain with the old traditional picture. Therefore, belief, disbelief, and suspension must map onto the new picture somehow. In this paper I challenge that possibility. Approaching the question from the angle of (...) suspension, I argue that all possible credal accounts face serious challenges. They either (i) falsify central claims that uphold the credal picture itself or (ii) do not permit suspension in cases where it is permissible or (iii) rule out the possibility of plainly possible confidence comparisons.

There are important similarities between moral thought and talk and thought and talk about gender: disagreements about gender, like disagreements about morality, seem to be intractable and to outstrip descriptive agreement; and it seems coherent to reject any definition of what it is to be a woman in terms of particular social, biological, or other descriptive features, just as it seems coherent to reject any definition of what it is to be good or right in terms of any set of (...) descriptive properties. These similarities give us reason to investigate the idea that, like moral thought and talk, gender thought and talk is inherently normative. This paper proposes a normative account of gender thought and talk in terms of fitting treatment. On this fitting treatment account, to judge that A is gender G is just to judge that it is fitting to treat A as a G. This account is a descriptive or hermeneutical account of our gender thought and talk rather than an ameliorative account of our gender concepts or a metaphysical account of gender properties in social metaphysics. This paper argues that other descriptive accounts of gender thought and talk face problems that the fitting treatment account overcomes. (shrink)

Knowledge implies the presence of a positive relation between a person and a fact. Factual ignorance, on the other hand, implies the absence of some positive relation between a person and a fact. The two most influential views of ignorance hold that what is lacking in cases of factual ignorance is knowledge or true belief, but these accounts fail to explain a number of basic facts about ignorance. In their place, we propose a novel and systematic defense of the view (...) that factual ignorance is the absence of awareness, an account that both comes apart from the dominant views and overcomes their deficiencies. Given the important role that ignorance plays in moral and legal theory and our understanding of various epistemic injustices, a precise and theoretically unproblematic account of the nature of ignorance is important not only for normative epistemology, but also for law, ethics, and applied epistemology.
