I am an Professor in the Department of Philosophy at Lewis & Clark College. My main areas of research interest are in the philosophy and history of science (especially biology and psychology) with strong interests in aesthetics and ethics. In the history of philosophy, I am especially engaged by the American pragmatists and their descendants. Here is my CV.
My research focuses on foundational issues related to the sciences especially in evolutionary biology and ecology. In my published work, I have examined a variety of topics including: the strategies that scientists employ to use highly idealized models in the face of limited data; the nature of species, communities, and ecosystems; the role of consensus, dissent, and advocacy in science and policy. Some of my papers are downloadable here. This year my short book entitled Ecological Models for Cambridge University Press will appear which explores many of these themes.
This fall I am finishing a book manuscript In a Sentimental Mood: Emotion, Evolution, and Expression. It is interdisciplinary exploration of what psychology, behavioral ecology, and evolutionary biology have to say about our emotions and their expression. In addition, I examine what light they shed on emotions in moral judgment and emotional expression in the arts.
In the tradition of American pragmatism, I believe philosophy can be deeply practical. It is help us solve the "problematic situations" we face as John Dewey put it. As recent examples, in 2009 I participated in a working group on the topic of "managed relocation" which is the deliberate movement of species due to anthropogenic climate change. This working group met to discuss the scientific, legal, and ethical challenges that managed relocation presents and our essay on the topic "Managed Relocation: Integrating the Scientific, Regulatory, and Ethical Challenges" has appeared in Bioscience. Here is a press release regarding the paper. In 2013, I participated in a conference and working group on de-extinction at Stanford University. In 2015, I participated in a workshop on denialism in science at Wake Forest University. In 2016, I participated in workshops at the Environmental Law Institute which brought together scientists, journalists, lawyers and one philosopher to discuss how to communicate scientific uncertainty more effectively. And, if you are curious, I was recently on the radio show Philosophy Talk in a discussion regarding the nature of wilderness and whether, and to what extent, Homo sapiens is simply another part of the natural world. And, this past year I gave a keynote address to the Fish and Wildlife Service conference here in Portland.
Philosophy in its best moments is about instilling intellectual accountability. As William James noted, "A great many people think they are thinking when they are really rearranging their prejudices." To understand our beliefs and values is important not only for intellectual reasons but for deeply practical reasons. Beliefs and values have effects — some beneficial and some not. It thus is of profound importance to be responsible for one’s view of the world and my teaching is first and foremost an attempt to bring students to understand and respect that responsibility.
