It has been argued recently that classical theism and Lewisian modal realism are incompatible theses. The most substantial argument to this effect takes the form of a trilemma. It argues that no sense can be made of God’s being a necessary being in the modal realistic picture, on pain of, among other things, modal collapse. The question of this essay is: Is that so? My goal here is to detail the reasons that have been offered in support of this contention (...) and then defend the coherence of theistic modal realism from the trilemma. I call my reply to the argument an “Anselmian-Thomistic” defense, since it appeals to resources from classical medieval philosophy, especially from Anselm and Aquinas. (shrink)

Essentialists suppose that for every individual, if that individual exists at any possible world, then necessarily that individual exemplifies some non-trivial qualitative property essential to it, as such. Anti-essentialists deny this. One important argument leveled by some anti-essentialists against essentialism takes the form of a thought experiment, one originally introduced by Roderick Chisholm, sometimes referred to as Chisholm's Paradox (CP). In this essay, I defend essentialism against CP. I begin by presenting the argument and showing how it leads to a (...) contradiction of the essentialist thesis. I then consider one of the most popular solutions to CP to date, that given by Nathan Salmon. Next, I critique Salmon's proposal and show that it is an insufficient response on behalf of the essentialist. And finally, I propose a novel solution to the paradox and discuss why it is that many metaphysician in the past have found CP plausible, despite being fallacious. (shrink)

The moral principle that Ought Implies Can (“OIC”) is often assumed without argument in normative discourse. Is this assumption defensible? Some would argue that it is not, as there are many purported counterexamples against it in the literature. However, OIC is not so much a single principle as rather a family of them. In this paper, I will argue that, while not every OIC-type principle is defensible, at least one of them may be. I defend the cognate moral principle that (...) Ought Implies Can or Could Have (“OICCH”). I first show that it is able to circumvent the traditional counterexamples to OIC. And then I show that OICCH is even more plausible than some of the best alternative OIC-type principles to date. The upshot of this paper is that those who find OIC compelling should consider accepting OICCH instead. (shrink)

Here I offer a critical evaluation of modalism about essential properties. To that effect, I begin by rehearsing Fine’s now infamous counterexamples to pure modalism. I then consider two recent defenses of it, offered by Livingstone-Banks and Cowling, respectively. I argue that both defenses fail. Next I consider the most plausible variety of impure modalism – sparse modalism – which has recently been defended by Wildman and de Melo. Skiles has argued that sparse modalism fails too. I argue that Skiles’s (...) counterexamples misfire; nonetheless, his conclusion that, like pure modalism, sparse modalism is too broad, is on the right track. And so, I offer an original objection – the sparse modal propria counterexample – to show that this is so. I conclude by considering ways the modalist might once again modify her account to circumvent this new objection and improve the account’s extensional adequacy. (shrink)

This is a paper on the philosophical clinical psychology of PTSD. How best to improve our treatment plans for the disorder is the primary imperative in the clinical literature. Our failure to properly treat those suffering from PTSD up until now could be either the result of merely a problem in practice or, more seriously, a problem in principle. In this essay, I explore three possible accounts consistent with the supposition that what we have here is a problem in principle. (...) I call the first the “Somatic” hypothesis; the second, the “Memorial”; and the third, a “Rilkean” hypothesis of PTSD, which is inspired by the recent work of M. Rowlands. The first two have been more-or-less articulated previously; the third is introduced here for the first time. The primary argument of this essay is abductive: I argue in favor of a Rilkean Memory hypothesis of PTSD by comparing it to the other two accounts and showing that it possesses greater theoretical virtue than they do. I then conclude the essay by noting certain limitations with the account here sketched, nonetheless suggesting that this hypothesis can open up new avenues of clinical research and treatment options for the disorder.

This essay offers an original interpretation and defense of the doctrine of flux, as it is presented in Plato’s Theaetetus. The methodology of the paper’s analysis is in the style of rational reconstruction, and it is highly analytic in scope, in the sense that I will focus on the text itself, and only on certain parts of it too, while ignoring the rest of Plato’s extensive corpus, and without worrying about whether, how, and to what extent the interpretation of the (...) view coheres well with the other elements of the secret doctrine view discussed in the dialogue, as well. In the first part of the essay, I’ll offer my interpretation of the doctrine. Then, in the second part of the essay, I’ll examine two potential criticisms of the doctrine, including Socrates’s infamous linguistic paradox, and show how my interpretation of Heraclitean flux metaphysics is able to circumvent both.

This essay offers a revisionist defense of classical utilitarianism from an infamous objection to it, which is derived from American science fiction writer, Ursula Le Guin’s, short story, “The Ones Who Walk Away from Omelas.” To that effect, the reply takes inspiration from Le Guin and John Stuart Mill in appealing to the natural law theoretical concept of conscience. I argue that a conscientious utilitarian ethic can escape Le Guin’s objection more satisfactorily than other popular utilitarian ethics. Along the way, (...) this essay discusses at length conscience and its place in moral epistemology, both as it occurs in the natural law tradition and in Mill. The natural law account of conscience is defended and Mill’s account is critiqued. Consequently, this paper also provides an interesting synthesis of utilitarianism with natural law ethics. (shrink)

The subject of this essay is propria and their relation to essence. Propria, roughly characterized, are those real properties of a thing which are natural but nonessential to it, and which are said to “flow from” the thing’s essence, where this “flows from” relation is understood to designate a kind of explanatory relation. For example, it is said that Socrates’s risibility flows from his essential humanity; and it is said that salt’s solubility in water flows from the essential natures of (...) both salt and water. The question I raise and attempt to answer in this essay is: In what sense do propria “flow from” essences? What kind of explanatory relation is this exactly? Some suggest that it is a relation of logical consequence ; others, of grounding ; and still others, of formal causation. In this essay, I reintroduce and defend a view suggested by the late scholastic Spanish philosopher and theologian Francisco Suárez, who in 1597 wrote that effluence is best understood as a very special kind of efficient causation, which we can call the relation of emanation. The thesis of this essay, then, is that propria emanate from essences. Along the way, this paper offers a new taxonomy of types of propria; it explains the significance of propria for the metaphysics and epistemology of essences; it discusses at length varieties of efficient causation ; and then it offers an extensive abductive argument in favor of Suárez’s account, whereby the former accounts of effluence are critiqued, each in turn, and Suárez’s view is motivated and ultimately shown to be superior to its competitors.

The purpose of this essay is exegesis. I explicate Nicolas Malebranche's (1674, 1678, 1688, 1714) concept of intelligible extension. I begin by detailing how the concept matured throughout Malebranche's work, and the new functions it took on within his metaphysical system. I then examine Gustav Bergmann's “axiomatic” interpretation, as well as the criticism of it offered by Daise Radner. I argue that Radner's criticism of the interpretation is only partly successful; some of her objections can be met; others cannot. I (...) then develop a novel interpretation of the concept, given insights from this dispute. I call it the “programmatic interpretation.” I argue that this interpretation coheres well with Malebranche's famous Vision in God thesis, as well as many of his other commitments. I conclude by considering a certain pertinent objection to my proposal, summarizing the dialectic, and forcefully restating my case. (shrink)
