However, when co-authoring The Point of View of the Universe (2014), Singer shifted to the position that objective moral values do exist, and defends the 19th Century utilitarian philosopher Henry Sidgwick's view that objective morality can be derived from fundamental moral axioms that are knowable by reason. Additionally, he endorses Derek Parfit's view that there are object-given reasons for action.  Furthermore, Singer and de Lazari-Radek (the co-author of the book) argue that evolutionary debunking arguments can be used to demonstrate that it is more rational to take the impartial standpoint of "the point of view of the universe", as opposed to egoism—pursuing one's own self-interest—because the existence of egoism is more likely to be the product of evolution by natural selection, rather than because it is correct, whereas taking an impartial standpoint and equally considering the interests of all sentient beings is in conflict with what we would expect from natural selection, meaning that it is more likely that impartiality in ethics is the correct stance to pursue. 
In time, it’s going to be impossible to deny that abortion is violence against children. Future generations, as they look back, are not necessarily going to go easy on ours. Our bland acceptance of abortion is not going to look like an understandable goof. In fact, the kind of hatred that people now level at Nazis and slave-owners may well fall upon our era. Future generations can accurately say, “It’s not like they didn’t know.” They can say, “After all, they had sonograms.” They may consider this bloodshed to be a form of genocide. They might judge our generation to be monsters.
Christensen ends her essay with a plea to New York readers to push the state Senate’s majority leader and health committee head, both Republicans, to bring the new legislation to the floor for a vote before the legislative session ends in late June. “Only percent of abortions happen after 22 weeks, but each of us has a unique story,” she writes. “I implore you to question any narrative that requires you to consider women to be monsters for protecting their own health, or for offering a merciful end to an unviable pregnancy.” The New York law would come too late for Christensen and thousands of other women, but for many others in similarly devastating circumstances, it could offer compassionate care just in time.
