Prof Max Bazerman’s book “Better, Not Perfect“:
Bazerman’s guiding light is the philosophy of utilitarianism, which teaches the goal of creating the greatest good for the greatest number of people. But he tempers that with the principle of “maximum sustainable goodness,” a term he coined based on the environmental concept of “maximal sustainable yield”—that is, the amount of goodness that a person can achieve over time without depleting their ability to do good in the future.
