Self-doubt can be the first step to moral improvement. But our biases are so subtle, alluring, and persistent that converting a wave of doubt into enduring wisdom takes work. The most-impressive cases of bias neutralization I’m aware of involve people who have spent ungodly amounts of time—several hours a day for many years—in meditative practices that make them more aware of the workings of their minds. These people seem much less emotion-driven, much less wrapped up in themselves, and much less judgmental than, say, I am. (And brain scans of these highly adept meditators have found low levels of activity in brain networks associated with self-regarding thought.)
Read the whole thing. I think he is saying that utilitarianism is insufficient as a moral framework, because utilitarians with too much hubris can be morally dangerous. Maybe you will read him differently.
Like every other belief or ethos, yes. Utilitarianism is harmful when taken to the extreme.
I would say that *every* moral framework is insufficient in and of itself.
Maybe less emotion-driven, self-regarding people are more likely to meditate.
