The Golden Rule (do unto others as you would have others do unto you) isn't bad, exactly -- it can serve a valuable role -- but I think there's something more empirically and ethically attractive about the relatively underappreciated idea of "extension" found in the ancient Chinese philosopher Mengzi.

The fundamental idea of extension, as I interpret it, is to notice the concern one naturally has for nearby others -- whether they are relationally near (like close family members) or spatially near (like Mengzi's child about to fall into a well or Peter Singer's child you see drowning in a shallow pond) -- and, attending to relevant similarities between those nearby cases and more distant cases, to extend your concern to the more distant cases.

I see three primary advantages to extension over the Golden Rule (not that these constitute an exhaustive list of means of moral expansion!).

(1.) Developmentally and cognitively, extension is less complex. The Golden Rule, properly implemented, involves imagining yourself in another's shoes, then considering what you would want if you were them. This involves a non-trivial amount of "theory of mind" and hypothetical reasoning. You must notice how others' beliefs, desires, and other mental states relevantly differ from yours, then you must imagine yourself hypothetically having those different mental states, and then you must assess what you would want in that hypothetical case. In some cases, there might not even be a fact of the matter about what you would want. (As an extreme example, imagine applying the Golden Rule to an award-winning show poodle. Is there a fact of the matter about what you would want if you were an award winning show poodle?) Mengzian extension seems cognitively simpler: Notice that you are concerned about nearby person X and want W for them, notice that more distant person Y is relevantly similar, and come to want W for them also. This resembles ordinary generalization between relevant cases: This wine should be treated this way, therefore other similar wines should be treated similarly; such-and-such is a good way to treat this person, so such-and-such is probably also a good way to treat this other similar person.

(2.) Empirically, extension is a more promising method for expanding one's moral concern. Plausibly, it's more of a motivational leap to go from concern about self to concern about distant others (Golden Rule) than to go from concern from nearby others to similar more distant others (Mengzian Extension). When aid agencies appeal for charitable donations, they don't typically ask people to imagine what they would want if they were living in poverty. Instead, they tend to show pictures of children, drawing upon our natural concern for children and inviting us to extend that concern to the target group.

(3.) Ethically, it's more attractive to ground concern for distant others in the extension of concern for nearby others than in hypothetical self-interest. Although there's something attractive about caring for others because you can imagine what you would want if you were them, there's also something a bit... self-centered? egoistic? ... about grounding other-concern in hypothetical self-concern. Rousseau writes: "love of men derived from love of self is the principle of human justice" (Emile, Bloom trans., p. 235). Mengzi or Confucius would never say this! In Mengzian extension, it is ethically admirable concern for nearby others that is the root of concern for more distant others. Appealingly, I think, the focus is on broadening one's admirable ethical impulses, rather than hypothetical self-interest.
