Normative ethics, especially virtue theory, drew me to philosophy. Since graduate school my active research has tended in the direction of methods in practical ethics and questions at the intersection of philosophy of disability and theories of well-being. I also write short stories when time allows. The moral theory questions I've moved to the academic back burner sometimes show up there.

"Humans Should Not Colonize Mars," Journal of the American Philosophical Association, Vol. 3, No. 3, 2017, pp. 334-353. [ doi | pre-print ]

This article offers two arguments for the conclusion that we should refuse, on moral grounds, to establish a human presence on the surface of Mars. The first argument appeals to a principle constraining the use of invasive or destructive scientific techniques. The second appeals to a principle governing appropriate human behavior in wilderness. These arguments are prefaced by two preliminary sections. The first preliminary section argues that authors working in space ethics have good reason to shift their focus away from theory-based arguments in favor of arguments that develop in terms of pre-theoretic principles and beliefs. The second argues that, of the popular justifications for sending humans to Mars, the justification of scientific curiosity alone survives reflective scrutiny.

The BBC World Service's In the Balance produced an episode on the ethics and economics of Mars colonization. I was privileged to participate along with Dr. David Parker (director of human and robotic exploration for ESA) and Bas Lansdorp (founder and CEO of Mars One). Our discussion touches on some of the content of "Humans Should Not Colonize Mars."

The inaugural issue of the Journal of Astrobiology and Space Science Reviews focuses on Martian biology. I contributed an invited commentary that includes an overview of the principle of scientific conservation, which I introduced in Section 3 of "Humans Should Not Colonize Mars."

"Fanciful Examples," with Jason Swartwood, Metaphilosophy, Vol. 48, No. 3, April 2017, pp. 325-344. [ doi | pre-print ]

This article defends the use of fanciful examples within the method of wide reflective equilibrium. First, it characterizes the general persuasive role of described cases within that method. Second, it suggests three criteria any example must meet in order to succeed in this persuasive role; fancifulness has little or nothing to do with whether an example is able to meet these criteria. Third, it discusses several general objections to fanciful examples and concludes that they are objections to the abuse of described cases; they identify no special problem with fanciful examples.

"Ways to Be Worse Off," Res Philosophica, Vol. 93, No. 4, October 2016, pp. 921-949. [ doi | pre-print ]

Does disability make a person worse off? I argue that the best answer is yes and no, because we can be worse off in two conceptually distinct ways. Disabilities usually make us worse off in one way (typified by facing hassles) but not in the other (typified by facing loneliness). Acknowledging two conceptually distinct ways to be worse off has fundamental implications for philosophical theories of well-being.

"Ways to Be Worse Off" won the 2017 Routledge, Taylor & Francis Prize awarded by the APA to the two best papers published by non-tenure-track faculty in 2016.

"Eight Lacunae," in Typehouse Literary Magazine Vol. 6 No. 1 (2019). [ publisher | gratis: all rights reserved ]

There's an art to liner notes. The best ones tend to be so dense with in-group references and proper nouns they can be difficult for anyone outside the band's inner circle to parse, yet a story somehow emerges, the warmer for its insulating layer. It was Chris Butler's notes for Best of the Waitresses and Byron Coley's for a series of Flesh Eaters reissues that convinced me that liner notes are an underexplored medium for narrative fiction.

"The Egg Collection," reprinted in Midwestern Gothic (Winter 2018). [ publisher | amazon ]

When I moved to St. Paul for graduate school, my parents gave me a membership to the Science Museum of Minnesota. Back then, the museum displayed an early-20th-Century collection of birds' eggs, which I loved and visited a few times a year. Along with hundreds of eggshells from all over the country, the curators included in the display a bird-egg price-guide from 1920. It got me thinking about the different kinds of people who might have been attracted to egg collecting, back in the day, and the different ways they might have valued their collections.

Midwestern Gothic posted a short "Contributor Spotlight" interview with me in May 2018.

"The Egg Collection" first appeared in South Dakota Review Vol. 51 No. 3&4 (2015), which sold out in a heartbeat.

"The Sort of Thing Everyone Knows," in Eclectica Vol. 21 No. 1 (Jan/Feb 2017). [ archived online ]

My family moved to Sacramento from a small town in central Ohio when I was eleven. The immediate and unforeseen effect of the move, for me, was the discovery that I like music. That discovery in turn caused changes to my world-view and character, some of which probably qualify as significant. This personal essay/memoir traces some specific consequences of my youthful mania for Erasure. It also functions as an elliptical characterization of my understanding of the limited but real role philosophical reflection can play in moral development.

"Conflagration" (as D.L.E. Roger) in This Is How You Die (Grand Central, 2013). [ amazon | gratis: cc by-nc-nd ]

T. Rex, star of Ryan North's "Dinosaur Comics," once fantasized about writing a story set in a world in which a simple blood test could determine, with perfect accuracy, the future cause of a patient's death. Ryan and some of his colleagues in the web-comic world pursued the idea, editing and publishing an anthology of stories using T. Rex's hook. It was an indie blockbuster, successful enough that they put together a second volume, which includes a story by me. (Visit the Machine of Death website for more information about the history of the anthology and its penumbra of spin-off projects.)


The Reward of Virtue [ archived online ]

Most work in neo-Aristotelian virtue ethics begins by supposing that the virtues are the traits of character that make us good people. Secondary questions, then, include whether, why, and in what ways the virtues are good for the people who have them. My dissertation is an argument that the neo-Aristotelian approach is upside down. If, instead, we begin by asking what collection of character traits are good for us-- that is, what collection of traits are most likely to promote our own well-being-- we find a collection of traits a lot like the traditional slate of virtues. This suggests an egoistic theory of the virtues: the virtues just are those traits of character that reliably promote the well-being of their possessor. In addition to making the positive case for character egoism, I defend it from some anticipated objections. Most importantly, I argue that character egoism doesn't inherit the problems of ethical egoism. I conclude by arguing that character egoism can account for two virtues traditionally thought beyond its reach: honesty and justice.

I defended my dissertation on June 17th, 2011. This is the précis I prepared for the open-to-the-public portion of the defense. It's a 20-minute presentation, intended for a general audience.
