So your first principle, on which you base your claim that zaps are counterproductive to the betterment of human social order, is serendipity? To which I would add, at risk of repeating, that for an incentive to lube the inner workings of the social contract, it does not have to be intended. Gifts, in this way, are like ideology: they work whether you believe in them or not. Or, as Yogi Berra said: “If you don’t know where you’re going, you’ll end up somewhere else.” A gift is still a debt owed, even if the horse has cavities or halitosis.
