Which golden rule of ethics?

The golden rule says: ‘Treat others as you want to be treated’. This article organizes contemporary interpretations of the rule into three groups: the ‘material’ golden rule, the ‘relativistic’ golden rule, and the ‘formal’ golden rule. The article also argues that (a) the relativistic golden rule is the weakest, (b) the formal golden rule is virtually irrefutable, (c) the material golden rule is less evident than the formal one, but not necessarily false and (d) the formal golden rule and the material golden rule are not incompatible—they can complement each other. This assumes that the substantive assumptions of the material golden rule are real.
