Abstract

This articles exposes the methodological errors involved in attempting to operationalize or value-neutralize the concept of 'terrorism.' It defends, instead, an effects-based approach to the taxonomy of 'terrorism' that builds out from a central conceptual connection between the term's negative connotation and a widely shared moral presumption against the killing of innocent non-combatants. Although this approach to the core meaning of 'terrorism' is far from value-neutral, it has a number of virtues to recommend it. First, it has the political virtue of even-handedness in the way it enables competing appraisals of asymmetric conflicts. Second, it is has the ethical virtue of being flexible enough to accommodate nuanced appraisals of various modes and degrees of terrorist violence. And third, it has the empirical virtue of being useful for purposes of rigorous social scientific research.
