Peter Singer is an Australian moral philosopher. He is perhaps the most famous contemporary utilitarian ethicist. His 1975 book Animal Liberation is sometimes cited as the beginning of the modern animal advocacy movement. He is also known for Famine, Affluence, and Morality, which argued that there is a strong ethical obligation to donate money to those who are less well-off, and influenced the development of the effective altruism movement. His more controversial views include arguing that parents should have a right to euthanize their severely disabled infants.
Singer has discussed Nick Bostrom's argument for the overwhelming importance of reducing existential risk, and is an advisor to the Centre for the Study of Existential Risk, although he has exercised discretion as he believes few are likely to be convinced. He believes that the interests of sentient machines should be taken into consideration, and that we should be doing more to ensure that advanced artificial intelligence will be ethical.
In the early 1990s, Singer wrote an article outlining some possible objections to radical life extension from a total utilitarian perspective. Mark Alan Walker has responded, providing some utilitarian arguments in favor of life extension, while Russell Blackford has argued that moral pluralist approach (rather than total utility view) can avoid the problems raised by Singer. More recently, Singer seems to have been persuaded by Aubrey de Grey that life extension research should be a medical priority.
