Abstract
The object of the exercise is to understand what we can do to stop something bad. It would be better if people stopped for the purest of motives, but it’s best if they stop. And if the choice is between their stopping for the wrong reasons and their not stopping I favour their stopping for the wrong reasons. Kant may be right that people ought to stop killing because they see that it’s wrong. That ought to be enough, but it may not be, and if it isn’t, if there’s something else that can actually get them to stop, then I favour using it.
