Philosophical Perspectives on the Problem of Extraterrestrial Signal Detection


Arthur C. Fricke




SETI (the Search for Extra-Terrestrial Intelligence) is, from a philosophical perspective, a unique scientific activity.  Given that SETI researchers purport to study a phenomenon that has yet to be demonstrated, some commentators have claimed that the field cannot in fact be called "scientific" at all, and/or cannot be legitimately differentiated from the study of UFOs, ancient astronauts, and other speculative phenomena commonly associated with pseudoscientific endeavors.  Drawing from work in the philosophy of science, particularly the philosophies of Karl Popper and Paul Feyerabend, this paper will examine whether SETI can be considered a properly scientific activity.  It will explore how basic SETI hypotheses can be framed in a philosophically well-grounded, logical manner.  Finally, this paper will survey some of the practical implications that different overall philosophical groundings may have for specific established approaches to the problem of intelligent extra-terrestrial signal detection, and argue for supporting widely divergent technical and theoretical detection efforts.
