  It would be a mistake to exaggerate the extent of moral disagreement. There is considerable psychological and anthropological evidence that a small number of core moral values are espoused universally, such as: benevolence (avoiding harm to others and offering aid when the costs are not high); fairness (reciprocating help and sharing goods); loyalty (especially to family and community); respect for authority (of one’s parents and community leaders, when it is exercised responsibly); personal purity in body and mind (notably as it reflects moral character); and freedom (especially from oppressive control by others). See Haidt 2012; Haidt &amp; Joseph 2004. Thus, when there is no conflict in moral values, as in Peter Singer’s famous example of rescuing a toddler from drowning in a shallow pond by wading into it and ruining one’s new suit, there is universal agreement about what a person ought to do across all cultures (Singer 1972).
