Then IFoR position labels some animal behaviour ethical, for no very strong reason, and then assumes that it translates into human interactions,
The indexicality of the IFoR solution is the real problem, "Predation is a moral value for predators" translates to "Mugging is a moral value for muggers"....but it's not so great for the victim/prey....and the function of ethics in human societies is to decide which behaviours get approved forbidden. So is mugging allowed?
Humans are animals affected by natural selection, wherefore no translation from animals to humans is necessary or even possible.
An individual is neither a predator nor a mugger by default. An individual is a predator or a mugger because of its traits and behaviour. Probably the mugger does not value the mugging itself. Humans who value the survival of their own behavioural genes would in all probability put into practice and enforce laws against mugging, since allowing mugging would risk adversely affecting not only each individual herself, but also other ...
I noticed that there has been some earlier discussion about Sam Harris’s Moral Landscape Challenge here at LW. As a writer on the Swedish politico-philosophical blog The Inverted Fable of Reality, I would like to share a response to the challenge, written by our main contributor, which I believe is interesting to read even if you are not familiar with The Moral Landscape or its content. See this link for the response and a short explanation of the challenge.
