I was reading the reviews on Amazon.com for the book The End of Faith, and noticed on of the reviewers citing the line bolded above. I then searched the book to find this quote in context. It appears the author, Sam Harris, advocates the idea that it may be ethical to kill someone for believing what he calls a "dangerous idea."The End of Faith, p. 52-53 wrote:The link between belief and behavior raises the stakes considerably. Some propositions are so dangerous that it may even be ethical to kill people for believing them. This may seem an extraordinary claim, but it merely enunciates an ordinary fact about the world in which we live. Certain beliefs place their adherents beyond the reach of every peaceful means of persuasion, while inspiring them to commit acts of extraordinary violence against others. There is, in fact, no talking to such people. If they cannot be captured, and they often cannot, otherwise tolerant people may be justified in killing them in self-defense. This is what the United States attempted in Afghanistan, and is what we and other Western powers are bound to attempt, at an even greater cost to ourselves and to innocents abroad, elsewhere in the Muslim world. We will continue to spill blood in what is, at bottom, a war of ideas.
Do you believe it is ethical to kill people for believing "dangerous ideas?" Why?
