Marc Hauser puts forth the theory that humans have evolved a universal moral instinct, unconsciously propelling us to deliver judgments of right and wrong independent of gender, education, and religion. Combining his cutting-edge research with the latest findings in cognitive psychology, linguistics, neuroscience, evolutionary biology, economics, and anthropology, Hauser explores the startling implications of his provocative theory vis-à-vis contemporary bioethics, religion, the law, and our everyday lives.

This paper argues that philosophers require a strict canonical definition of terrorism if they are to be of any use in morally evaluating the changing character war. This definition ought to be a narrow, critical one, articulating precisely what is wrong with terrorism and strictly specifying which incidents fall into this derogatory category and which do not. I argue against those who avoid definitions or adopt wide and apologetic ones. The latter claim neutrality for themselves and accuse those who define (...) terrorism strictly of political bias. The apologetics of terrorism often allege that stringent, critical, definitions of terrorism beg important questions of justification, rendering terrorism unjustifiable by definition. The apologetics of terrorism however, have an obvious political agenda. Those who deliberately blur the distinctions between terrorism and other forms of violence cannot claim academic ?neutrality? or ?objectivity? for their wide, defensive definitions, which are in fact deliberately designed to advance particular political views.

Elaborating on the notions that humans possess different modalities of decision-making and that these are often influenced by moral considerations, we conducted an experimental investigation of the Trolley Problem. We presented the participants with two standard scenarios (‹lever’ and ‹stranger’) either in the usual or in reversed order. We observe that responses to the lever scenario, which result from (moral) reasoning, are affected by our manipulation; whereas responses to the stranger scenario, triggered by moral emotions, are unaffected. Furthermore, when asked (...) to express general moral opinions on the themes of the Trolley Problem, about half of the participants reveal some inconsistency with the responses they had previously given.
