[more notes for the adv. alt. paper]
The question of whether the advantageous altruism with which this paper is concerned is morally worthy or not cannot be elided, whether or not it can be answered. From a Smithian/Humean/Aristotelian perspective, the answer is yes. Morality only makes sense if in some broad sense it aligns with interest, and the historical growth in respect for anonymous others, to the extent it has indeed occurred, is a function of respect, trust, and benevolence being in people's interest now in a way that they once were not. From a Jesus/Kant perspective, the answer is no. The beauty, truth, and supreme goodness of morality inheres in its challenge to mere common sense, complacency, and calculation as well as to outright evil. Only if one is as a little child, or as a god-like follower of duty who kills inclination and evil even to point of killing himself can one truly reside at the right hand of the father in the kingdom of heaven or the kingdom of ends.
The differences between the Smithian and the Jesus/Kant perspectives are intensely felt by partisans on both sides. Not only is there the contempt of the idealist for the seeker of advantage; there is also the contempt of the practical man for an idealism that the practical man sees as a cover for the power-seeking that the practical person suspects is the actual meaning or "cash value", to borrow William James's phrase, of the moralist's idealism.
My personal sympathies in the ideological opposition between the practical man and the idealist lie mostly on the former side. I believe that future progress not only in practical standards of living and everyday morality but also in scaling the pinnacles of theoretical ethics is much more likely to come from developments on the Smithian side than the Kantian side of modern ethics, and I have a similar belief about the generally impressive if highly zig-zag progress our species has achieved over the past several hundred years.
At the same time, I as one who is on the Smithian side both as a matter of methodology and as a matter of sympathy have an apologia to make to Kantian friends and opponents who may well be offended by the calculating spirit of this paper: You are right, in a very important sense. Absent a clear disclaimer, you are warranted in believing that the Smithian argument of this paper is one little piece in a bigger claim that the truth, goodness, and beauty of morality lies on the Smithian side. I strongly disclaim any such belief. I affirm on the contrary a belief that the bulk of the truth, goodness, and beauty of morality lies on the Kantian side, not on my own Smithian side. Lest this be taken as a much stronger renunciation than it is actually is, I also hasten to affirm a belief that morality is only one piece of life, and not necessarily the most important piece at that.
To put the point another way: I strongly agree with and affirm the Joshua Greene claim that Kantianism gets and articulaters the human moral gut in a way that utilitarianism does not. I also empathize with what I take to be Greene's bent toward utilitarianism, which I share. But--although I may be reading him quite wrong--I do not agree with what seems to me his implicit Kantian argument that utilitarianism is nobler for philosophers (though not for merchants) because it rises above our guts just as Kant counseled, while Kant himself does not. I'm with Smith, or where I take Smith to be, all the way down. Human nature is okay, even pretty good. To the extent it's not, let's imagine that it's a bit better than it is and use our moral imagination as a basis for our getting along a bit better with each other. Being pretty decent along with other people who are pretty decent is pretty good. And yet: A Jesus who is truly impelled by duty, love, self-sacrifice, justice, etc. is indeed a much finer type than me and thee. Jesus and Kant not only rule the moral world; they deserve to.
