This book borrows from the intellectual labor of queer theory in order to unsettle--or "queer"--the discourses of "religion" and "science," and, by extension, the "science and religion discourse." Drawing its intellectual and social cues from works by influential theorists such as Michel Foucault, Judith Butler, and Eve Sedgwick, queer theory begins with the idea that assumptions about heteronormativity, monogamy, gender and sexual dimorphism, among other norms, are not merely natural but also culturally constructed: they have a history which includes traditions, politics, and power dynamics. Extending this assumption to all ideas about what is natural, universal, and given ultimately suggests that reality is more complex and far stranger than any thought, idea, system, or belief can capture. While the scientific method of exploration and deconstructive strands of religious thought both have mechanisms that unsettle and challenge truth claims--and in this sense are much "queerer" than popularly imagined--such iconoclastic streams within religious and scientific thought often give way to the institutionalization of more solid ways of understanding reality. Because queer theory is at heart about continuing the conversations and explorations of the world in which we live, rather than arriving at any final conclusion about the "true" nature of reality, it helps to keep these conversations flowing and open in an ever-changing world. In this sense, there are at least three common features of queer theory on which all of the chapters in this volume converge. First, queer theory challenges givens that on occasion still undergird religiously and scientifically informed ways of thinking. Second, it takes embodiment seriously. Third, this engagement inevitably generates new pathways for thinking about how religious and scientific "truths" matter. These three features ultimately lend support to critical investigations into the meanings of "science" and "religion," and the relationships between the two.
