“When the truth is, their adherence to such absurdly costly principles is precisely to signal that, compared to those who cannot afford their morality, they have it easy.”
I think the idea that “morality is a form of signalling” is inaccurate. I agree that moral principles have an evolutionary explanation, but I think that standard game theory provides the best explanation. Generally, it’s better to cooperate than to defect in the iterated prisoner’s dilemma; and the best way to convince others you’re a cooperator is to be, truly, madly and deeply, a cooperator.
Cf. Elizier’s claim that he wouldn’t break a promise, even if the whole of humanity was at stake. It certainly makes him seem more trustworthy, right?
Yeah. But it’s certainly possible for both to theories to be true. Morality is a pretty big umbrella term anyway. Also, evolution likes to exapt existing adaptations for other functions.
