On Diachronic, Synchronic, and Logical Necessity
According to EJ Lowe, diachronic necessity and synchronic necessity are logically independent. Diachronic possibility concerns what could happen to an object over time and therefore concerns future possibilities for that object given its past history. Synchronic possibility concerns what is possible for an object in the present or at a past present moment. These are logically independent, given certain assumptions. While it may true that because I am 38, it is impossible diachronically for me to be 30 (at least once we restrict the degree of relevant possibility), it is possible, given that at some point in the past, I may have been conceived slightly earlier than I was, that I am now 37. Likewise, it is possible diachronically for me to be somewhere other than where I am, but given that one object cannot be in different places at the same time, it is impossible for me now to be somewhere other than where I am, and this is true at each past point in my history too. There are, then, two axis upon which to distinguish what is and is not possible: tensed possibilities and possibilities of degree, which include nomic, metaphysical, and logical necessities, among others. I examine the interactions between these possibilities and I come to the conclusion that logical necessity is not in fact logical necessity simpliciter. Whether something is logically necessary depends upon tensed possibilities. I argue that while synchronic logical necessity entails diachronic logical necessity, the reverse entailment does not hold. I explore the consequences of this for certain philosophical debates in semantics including the concept of rigid designation, and descriptive names. 

It's Easy Being Free: Notes on Frankfurt-Style Real Self Conceptions of Free Will (with Noah Sider)
On Frankfurt's view of free will, in its simplest form, an agent is free just in case her second-order volitions -- those second-order desires she wishes to be effective -- are in accord with her first-order volitions -- those first-order desires that one actually acts upon. That is, an agent has free will just in case she has the desires she wants to have and they are the desires she acts upon. But now consider an agent who lacks free will because her first-order volitions and second-order volitions conflict. Suppose also that, with enough therapy, she could alter her first-order volitions to be in accord with her second-order volitions. So it is true that she can alter her first-order volitions. Still, there is the question of what she should she do. A natural response that a real self theorist might make is that the agent should change her first-order volitions in order to reflect her second-order volitions. But this is not, in principle, the only option available to our agent. Instead of changing her first-order volitions to reflect her second-order volitions, she might also consider simply revising her second-order volitions to fit with her first-order volitions. In fact, since second-order volitions are arguably more reasons responsive, it could turn out for our agent that changing her second-order volitions is actually the most rational option to take. This applies to even the most recent developments of real self, hierarchical, reasons responsive, and even intention embedded accounts of free will. Indeed, there is empirical evidence that people change their conceptions of themselves quite readily in the face of cognitive dissonance of the kind faced by desire conflicts. But this way of attaining free will does not seem to comport with our conception of a free agent. Free will seems too easy to obtain if all that is required is that our second-order volitions are in accord with our first-order volitions, and I see no particularly principled way of arguing that we shouldn't consider changing our second-order volitions instead of changing our first-order volitions. Secondly, this conception of free will is also subject to Gettier style counter examples. A person, for instance, may not be able to respect hierarchies due to some personality trait or other, but she might also be the kind of person for whom even were this trait lacking, still would not want to respect hierarchies. Here we have case in which a person's first order volitions and second order volitions coincide, but we do not want to call her free either. Additional evidence that this cannot be the right conception of free will comes from ideas put forth in the literature on practical rationality: I can be in situations in which the only rational action for me to take is to change my desires (MacIntosh), but many think that we cannot make irrational decisions assuming we know that a certain action would be irrational. I conclude, then, that any compatibilist conception of free will of the kind mentioned will be ultimately unsatisfying.

The Contingencies of Ontological Commitment
Some time ago, Quine once asserted that to be is to be value of a variable. This entails that if one wishes to accept any theory as true, we must be committed to the existence of those objects over which we existentially quantify. I suggest instead that we are committed to the existence only of those things that have at least some intrinsic contingent properties. Any discourse that involves existential quantification over entities whose instrinsic properties can change will, of necessity, be given an objectual interpretation. In contrast, by default, all discourse that involves existential quantification over objects all of whose instrinsic properties are essential will be given a substitutional interpretation, leaving open room for debate about whether the discourse in question ought to be given an objectual interpretation. This alternative conception of what constitutes ontological commitment does not entail that we must be committed to the existence of mathematical entities, sets, or even of properties. However, it can still make good sense of the disagreements over whether such entities exist. Those disagreements are disagreements about how to understand the relevant quantifiers. 

Free Will and Foreseeability 
For many of us, at least, some of the most important events in our lives were not foreseeable. Indeed, for many of us, the trajectory of our lives in retrospect is often completely unexpected. We can, it seems, predict very few of the results of our efforts at controlling our lives. Particularly troubling is that this phenomenon seems to affect us exponentially in the long term, and some of our most important goals in life are long-term goals. What's more, is that attending more closely to the micro-effects of our actions on the world does little to alleviate this problem, since our efforts alone are not sufficient to determine the outcomes of our actions, as Nagel's discussion of moral luck taught us. Of course, there are those whose life trajectory seems entirely predictable in retrospect, leading to the belief that we are in control of our lives after all. However, it is not clear that such reasoning is much more justified than the reasoning that leads people to conclude that Nostradamus must have been predicting the future given that things turned out as he said. Because the unpredictability of our lives is so prevalent and the status of cases in which they do seem predictable are unclear, I conclude that the existence of the kind of free will that seems matters to us, the kind that determines our life paths, is largely a myth. But, on the positive side, taking my cue from Wolf's work on moral saints, I also conclude that since having this kind of free will would likely make our lives much less interesting, perhaps we shouldn't care about having it after all. 

Meta-Ethics
The Inevitability of Death: Going from an Is to an Ought
Since Hume, many ethicists have assumed that inferring normative claims from descriptive claims is fallacious. Some classic examples that illustrate this fact are those in which everyone commits some act, but we do not therefore conclude that it is the right thing to do. Everyone may jump off a bridge, asserts your mother, but that does not entail that you should. However, not all such claims illustrate this. In fact, some of them illustrate precisely the opposite claim. For example, consider the person who repeatedly bemoans the unfairness or sadness of dying, and who is often faced with the response that this happens to everyone. What should she do? One plausible response is that she should accept the fact that this occurs and make her peace with it, an unequivocally normative directive. This example, then, is a prima facie counterexample to the infamous gap between is-claims and ought-claims. Of course, if one accepts the ought-implies-can principle, then this example is merely an application of its contrapositive. However, one might instead believe that examples such as these are what ground such a principle, or one might reject such a principle and still accept this as a counterexample to the is-ought gap, nevertheless.
   
Philosophy of Language
Performative Meta-linguistic Actions
At least one of the issues surrounding proper names is how to understand the act of naming itself. Thus far, there has been little in the way of analysis of this phenomenon, save for using certain buzz words like "dubbing" or "christening" or "baptizing." The views that have been developed -- the causal theory, and the property attribution theory -- fail.  Unlike the latter, I hold that an act of naming must in some way be meta-linguistic. And, unlike the former, I also hold that naming is not grounded in objects of reference themselves, but rather speakers' intentions. There are, however, several objections to this understanding of naming. I will argue, by relying on a distinction due to Austin -- the performative-constative distinction -- that we can understand naming as fundamentally a meta-linguistic action so long as we recognize performative meta-linguistic types of speech acts. Austin pointed out that by using certain expressions, we could thereby make certain things true. My claim is that we can achieve the same effects, at least in cases of naming, simply by mentioning an expression. 

The Problem with Meta-linguistic Analyses of the Meanings of Proper Names
Some time ago, Kripke argued that meta-linguistic analyses of proper names were utterly uninformative. I suggest here that his objection relies on conflating the language used to talk about a particular language L -- the meta-language -- with direct speech reports made within a language -- the object language. Making this distinction leads to an understanding of meta-linguistic analyses of proper names that are not simply tautologous, so long as we do not understand the meta-linguistic analysis of, say, the expression 'quark' in the following way: the expression 'quark' is whatever we call a 'quark'. Instead, we should understand the analysis in the following way: the expression 'quark' is whatever we call a "quark," where the double quotes represent an act of reporting on direct speech, leaving open the possibility that a theorem like this can be informative insofar as we might be able to learn the meaning of the expression 'quark' by examining instances of the use of the expression "quark," Quinean worries aside. 
Philosophy of Mind
Against False "Pretences"
Any plausible account of the act of pretending, either by presupposition or constitution, involves an assumption that the facts are other than what they are. An examination of various accounts of pretence shows this to be the feature that distinguishes it from other actions such as imagining, fantasizing, creating, or hypothesizing. This discovery has implications for standard analyses of the nature of fiction. To wit, whatever is occurring when engaged in reading a work of fiction, it is not an act of pretence, since in reading a work of fiction, whether the facts are other than what they are is irrelevant to understanding and enjoying the story. The rather long history of appeals to pretence to explain the nature of fiction and our engagement with it, then, fail.

Social Ontology
Fractured Selves and Personal Identity
Selves or persons are fundamentally psychological in nature. However, many accounts of that psychological nature involve making two separate assumptions: (a) that selves should be integrated, and (b) that we can understand ourselves as psychological beings independent of our embedding environments. These assumptions are intertwined in a particular way: the possibility of an integrated self depends upon whether a person can be understood independently of its embedding environment.
Both assumptions are mistaken for a specific reason. While the integrated self is an ideal we hold dear, it is one that can be pursued only by those who have adequate control over their environments, a luxury reserved only for the most privileged among us. For many of us, even attempting to achieve an integrated self is beyond our grasp, those of us who may have been raped, who live as outsiders within, who have mental health issues, or who are members of groups that have faced historical and current forms of oppression. Such circumstances produce what we might call “fractured selves,” selves that face a multitude of environmental forces many times thrusting contradictory norms, roles, and traits, upon those subjected to them. These considerations raise the issue of whether an integrated self is a goal even worth pursuing. That is, the facts about who can pursue and potentially achieve an integrated self make assumption (a) questionable, at the least. Secondly, the role that many persons’ standing plays in undermining (a), a standing which does not permit much in the way of environmental manipulation, results in undermining assumption (b). 
It is therefore plausible to think that understanding selves or persons correctly requires rejecting (b), and replacing it with an alternative view on which we understand persons as fundamentally dependent upon their environments — that their identities ought to be understood as constituted not only by internal psychological relations, but also by their external relations to their surrounding environments. This is a view that can accommodate fractured selves as full persons, and it can allow for various psychological configurations to satisfy the criteria for being a person. 
Having a view that can accommodate those with fractured selves as persons is preferable to views that require integration. It is preferable, for instance, even to narrative views of the self — the idea that we construct our personal identities by constructing a coherent narrative about ourselves. While this view allows for some fluidity in what counts as psychological continuity than the standard theories of what constitutes psychological continuity, which require similarity between adjacent stages of a person, it nevertheless makes being a person depend upon having an integrated self, again, a condition not met by many who plausibly count as persons by anyone's measure. Even further, however, and perhaps surprisingly, it is also preferable to views that are externalist, but that bind selves to their socio-political contexts. Such theories are often offered as replacement theories for internalist psychological views, known as social constitution views; persons should not be understood as having an intrinsic nature independent of their social environment. Selves are socially relational, and this relationality can accommodate various kinds of psychologies as satisfying the criteria for being a person. Nevertheless, the idea that selves are constituted by social relations may bind persons too closely to their particular socio-cultural context. In contrast, a view like the one advocated for above, understands persons as dependent not only on social relations, but also upon other non-social relations to their environments. This view has the advantage of allowing not only for various kinds of psychologies to satisfy the criteria for personhood, it also frees persons from particular socio-cultural contexts, a welcome alternative for those whose privilege does not allow them the luxury of pursuing an integrated self, and who yet need an avenue of resistance against their current socio-cultural context.

Why Narrative and Social Constitution Views of the Self are not Enough
An alternative view to standard psychological continuity theories is the idea that we construct our personal identities by constructing a coherent narrative about ourselves. While this view allows for more fluidity in what counts as psychological continuity, it nevertheless makes being a person depend upon having an integrated self, a condition not met by many who plausibly count as persons by anyone's measure. A replacement theory often put forward is the social constitution view. Persons should not be understood as having an intrinsic nature independent of their social environment. Selves are socially relational, and this relationality can accommodate various kinds of psychologies as satisfying the criteria for being a person. Still, the idea that selves are constituted by social relations may bind persons too closely to their particular socio-cultural context. I argue that we should understand persons as dependent not only on social relations, but other non-social relations to the environment. This view has the advantage of allowing not only for various kinds of psychologies to satisfy the criteria for personhood, it also frees persons from particular socio-cultural contexts, a welcome alternative for those whose privilege does not allow them the luxury of an integrated self, and who yet need an avenue of resistance against their current socio-cultural context.

Social and Political Philosophy
"No" means "No:" Feminist and Victim Understandings of Sexual Assault (public address)
While there are many different motivations for raising questions about the Sexual Assault Awareness Movement, at least one motivation comes from feminist controversies about what counts as consensual sex. Historically, this controversy arose between those known as "anti-pornography feminists", and "sex positive feminists" whose proponents had very different understandings of what counts as sexual autonomy for women. It is important to understand that questioning the current definitions of what counts as an instance of sexual assault does not entail an anti-feminist agenda. There is not a unified feminist front on this topic. To assume otherwise is to risk silencing victims of sexual assault even further by imposing a particular conception of sexual assault upon them that they might themselves reject. If we are to properly address sexual assault as feminists we must listen to victims of sexual assault and develop a theory of consent in tandem with victims' own understanding of that concept.
