Peter Singer Quotes
We see things like reciprocity which are fairly central to our view of ethics. But if you're talking about a set of worked-out rules on what we are supposed to do then, yes, it is a human product.

Peter Albert David Singer AC is an Australian moral philosopher, currently the Ira W. DeCamp Professor of Bioethics at Princeton University. He specialises in applied ethics and approaches ethical issues from a secular, utilitarian perspective. He is known in particular for his book Animal Liberation (1975), in which he argues in favour of veganism, and his essay "Famine, Affluence, and Morality", in which he argues in favour of donating to help the global poor. For most of his career, he was a preference utilitarian, but he stated in The Point of View of the Universe (2014), coauthored with Katarzyna de Lazari-Radek, that he had become a hedonistic utilitarian.
