Cullen Murphy has a great, and horrifying, article that draws a straight line from the Dark Ages to today:
The public profile of torture is higher than it has been for many decades. Arguments have been mounted in its defense with more energy than at any other time since the Middle Ages. The documentary record pried from intelligence agencies could easily be mistaken for Inquisition transcripts.One big difference—today, it's worse:
The Inquisition, with its stipulation that torture and interrogation not jeopardize life or cause irreparable harm, actually set a more rigorous standard than some proponents of torture insist on now. The 21st century’s Ad extirpanda is the so-called Bybee memo, issued by the Justice Department in 2002 (and later revised). In it, the Bush administration put forth a very narrow definition, arguing that for an action to be deemed torture, it must produce suffering “equivalent in intensity to the pain accompanying serious physical injury, such as organ failure, impairment of bodily function, or even death.” To place this in perspective: the administration’s threshold for when an act of torture begins was the point at which the Inquisition stipulated that it must stop.
