The Structure of Explanations and Counter-Explanations of Homosexuality

The aim of this paper is to revisit an ongoing controversy within the so called “Science Wars”; more specifically, I will address a particular topic within the “human nature” debate: the ontological and epistemological status of homosexuality. I claim that, in this particular chapter of the “Science Wars”, we are continually left in an explanatory impasse even when more data are collected, more rigorous experimental techniques are developed, more subtle arguments are offered and more pluralistic narratives are told. My diagnosis of the source of this impasse leads me to the conclusion that here we are dealing with a structural problem that cannot be solved with an elaboration of new models and theories that maintain an on- tology and an epistemology that are no longer suited as an explanans of human nature in general, and homosexuality in particular. Nevertheless, my analysis of the structural features of the biological explanations and the constructivist counter-explanations also leads me to the belief that, although biologists do not fully understand the intricacies of subjects, neither constructivists understand the facticity of evolution and the challenge that it implies. If so, then the subject might be the right target of explanation. And, if so, constructivists might be right about the uniqueness of human homosexuality as a modern, western phenomenon explainable in terms of subjectivities and identities that mold and are molded by desires and institutions. But, if they are, evolution is not expendable because now we are facing a most intriguing question: How is that we humans became subjects?
