Abstract

Future technology may dramatically extend the human lifespan. Peter Singer argues that we should reject life extension because developing it would result in a world with lower total and average happiness. Singer’s argument depends on the claim that we should maximise average happiness per moment. I will argue that developing the life-extending drug would not be impermissible because doing so will maximise average happiness per person. I offer an independent argument for why we should adopt a consequentialist principle which says to maximise average happiness per person.
