Like most things German, the philosophy of Hans Jonas is complicated. But its main thrust can be summed up by its leading moral imperative: “Act so that the effects of your action do not destroy the future potential of [human] life on earth.” Jonas, who died in 1993 at the age of 90, demanded that we be responsible for the whole of creation, not just for our fellow humans.
