In the UK we are being treated to a rich and enjoyable series of programmes on Justice featuring Michael Sandel . No doubt there will be quibblers, but I think he’s done a great job so far. Last night’s episode discussed Bentham, Kant and Aristotle and, for my money, both utilitarians (in the shape of Peter Singer) and various German Kant-fans came across as slightly unhinged. The moment that most summed this up, however, was discussion of the German Constitutional Court’s Kant-inspired dismissal of a law that would allow the federal authorities to shoot down a hijacked airliner destined to crash into a city with catastrophic loss of life. Judgement here . According to these Kantians, even if the passengers are doomed to die in the next few minutes and shooting-down the plane will save many lives on the ground, to attack the airliner would show a lack of respect for their human diginity, purposiveness, endiness etc. and so is forbidden. For me, that looks like a reductio.
