[Working on my advantageous altruism paper for the 1/10/12 Academy of Management deadline and then for business ethics journal submission...some draft notes for the "Jesus" section of the paper follow...comments welcome as always]
If your enemy hits you on the cheek, turning your other cheek, rewarding as it may well be in giving one a satisfying sense of moral superiority, does not seem to have much potential as a way of getting ahead in the world. The fact that a preacher of a gospel of turning the other cheek and loving one's enemy became the central figure of the world's most widely followed religion, though in some sense a confirmation of the idea that altruism can in some fashion redound to one's practical benefit, is also a profound challenge to that idea. Compared to Plato and Aristotle, with their successful lives and their notion of a virtuous character whose self-interest lies in following the good, Jesus with his disastrous end and his notion of radical self-sacrifice is on the face of it a great rebuker of the notion of advantageous altruism. Think not of the morrow...be not like unto the Pharisees...it is easier for a camel to pass through the eye of a needle than for a rich man to enter the kingdom of God: In all of these maxims attributed to Jesus one senses a spirit radically opposed to calculation and to a morality of egoistic prudence and self-advancement.
And yet, the logic of relative success and resultant Darwinian advantage in cultural reproduction is not simple. It can be the case that the way to get ahead is to disdain getting ahead, and that the way to win is to disdain winning and indeed to embrace outcomes in which one loses. In what follows, I will trace out a claim that the Jesus of the Sermon on the Mount can be reasonably understood as advocating not only self-sacrifice that loses in practical if not moral terms, as he indeed does, but also as advocating a form of altruistic forgiveness that is highly advantageous to the forgiver in his interactions with an egoist. Further, I will suggest that this advantageous form of forgiving altruism has two great virtues compared to the egalitarian altruism of Plato and the masterful altruism of Aristotle. First, forgiving altruism solves an important family of assurance (or trust) games that are not solved by the Platonic or Aristotelian forms of altruism. Second and even more important, forgiving altruists do well with other forgiving altruists. Not everyone can be a successful egalitarian guardian or great-souled man, but everyone in a society can be successful together as forgiving altruists playing games with other forgiving altruists.
The basic idea of advantageous forgiving altruism can be stated as follows: You as the forgiving altruist have a deep positive feeling for the other's payoff, for yourself, and for the situation when you as the forgiving altruist choose an action that could or should result in the highest combined payoff for both of you (with either the best payoff for you and the second best for the other, or the second best payoff for both of you), but the other player "messes up" by choosing an action that gives both of you lower payoffs than you could have enjoyed. The basic concept is expressed much more succinctly in Luke 23:34: "Jesus said, Father, forgive them; for they know not what they do."
Forgiving altruism as just defined is helpful to the forgiving altruist because it amounts to a commitment to play a strategy that is as good as or better for the forgiving altruist as it is for the other player when the other player responds optimally to the commitment. It is also good for the other player--though not quite as good as it is for the forgiving altruist--because the other player receives no worse than her second best payoff, and may well receive her best payoff along with the forgiving altruist.
Although forgiving altruism is not an approach that wins for the altruist or for both players collectively in all games, it has a considerably broader sweep than egalitarian altruism and masterful altruism do. While those two types of selective altruism are effective in three out of the seven games of interest, forgiving altruism is effective not only in Leadership and the Battle of the Sexes, but also in the three assurance games--Trust, Schelling, and Stag Hunt. The only games on which it has no purchase is the Prisoner's Dilemma, where no form of selective altruism can have any purchase given the dominance of non-cooperation for the egoist, and Chicken.
In Chicken, the Greek altruists rule the roost because of their commitment to lead, which causes the egoist to yield. By contrast, the forgiving altruist as defined here does not commit to lead, because doing so would stick the egoist with her second worst payoff. (footnote--A less nice variant of forgiving altruist--Jesus with more Aristotle in him?--who commits to the highest value outcome when it is best for him even when it would stick the other player with a second worst outcome does win Chicken with an egoist. Further, that un-nice but forgving altruist avoids lead-lead wrecks in Chicken with another un-nice forgiving altruist because both commit only to a highest joint value outcome.) The result is that the game is up for grabs with a forgiving altruist and an egoist (or two forgiving altruists), just as it is in a game with two egoists. (footnote--Socially, the "up for grabs" outcome in Chicken in which both players play mixed Nash is not as good as the outcome in which the leader gets first best and the follower gets third best. That is the one case in which the Greek altruists socially outperform the forgiving altruist in interactions with an egoist.)
The Greek altruists clean up in the two pure leadership games. By comparison, the forgiving altruist takes a smaller though still preponderant share of the pie in Leadership and Battle of the Sexes games with an egoist. The reason is that the forgiving altruist as defined here, unlike the Greek altruists, does not play the strategy that gives her the highest payoff if it is not also the strategy that has the highest joint value. That restraint has the very considerable virtue of allowing two forgiving altruists to do very well indeed in playing leadership games with one another. (footnote--One will get his or her highest value payoff, and the other will get her second highest value payoff.) But it also means that the forgiving altruist will not commit to leading if the highest joint value outcome is for the egoist to lead. In those situations, the game between a forgiving altruist and an egoist is up for grabs, as it is in a game between two egoists. (footnote--A nicer type of forgiving altruist than the basic type defined here has a warm glow when the other messes up by deviating from an outcome in which the forgiving altruist earns her second highest payoff and the other earns her highest payoff. That type does not beat the egoist in leadership games; combined with the fact that the basic type as defined here does not beat the egoist in assurance games, the result is that the nicer variant on forgiving altruism does not prevail over the egoist overall, though it also does not lose to the egoist.)
In the three assurance games--Trust, Schelling, and Stag Hunt--the forgiving altruist as defined here does not beat the egoist. In these games, the best payoff for both players comes if they both trust. The "forgive them" commitment by the forgiving altruist to play trust leads to both players getting their best outcomes, not to a win over the egoist by the forgiving altruist. (footnote--A less nice variant of the forgiving altruist that is only committed to trust when his cardinal payoff is at least as high as the other player's will prevail over the egoist. Such a less nice or competitive forgiving altruist will not throw away value in playing assurance games with another un-nice forgiving altruist, since both players will recognize and follow the other's commitment and coordinate on trust-trust.)
Overall, the forgiving altruist does not take the egoist to the cleaners the way the Greek altruists do. But the forgiving altruist does indeed outperform the egoist. And crucially, the forgiving altruist does even better in interactions with another forgiving altruist than she does with an egoist. In contrast with the guardian and the great-souled man, who are both elite types, the forgiving altruist is an excellent candidate to be a general or universal type.
