The Trolley Problem - a podcast by BBC Radio 4

In 1967, the philosopher Philippa Foot developed a thought experiment about a runaway trolley. It involved countless dilemmas designed to illustrate human behaviour.

But whatever the scenario, the rhetoric was always the same....the overwhelming desire was for the trolley to kill fewer people and save more.AL Kennedy argues that today that rhetoric is in danger of being turned on its head.

Producer: Adele Armstrong.
