This article is about the religious roots of violence, in particular religious terrorism. The author argues that there is a great reluctance to study this relationship. This is unfortunate because only on the basis of a realistic estimate of the facts can a successful counterterrorist strategy be developed. One of the problems with religious violence is that holy scriptures, in some passages, exhort believers to violent acts. In combination with a theory of ethics that is known as “divine command morality” (...) this is problematic. Even if the holy book contains only a small percentage of passages invoking violence they pose a problem if the whole book is considered to be holy and the word of God. (shrink)
