I am one of the few people I know of who has argued in print that torture may be an ethical necessity in our war on terror.

If our well-being depends upon the interaction between events in our brains and events in the world, and there are better and worse ways to secure it, then some cultures will tend to produce lives that are more worth living than others; some political persuasions will be more enlightened than others; and some world views will be mistaken in ways that cause needless human misery.

Unfortunately, failure enjoys a natural advantage. Wrong answers to any problem outnumber right ones by a wide margin, and it seems that it will always be easier to break things than to fix them.
