Brooks repeated this formulation from his earlier Sewanee speech because it captured the 'inverse logic' at the heart of his argument. The moral world, he told Dartmouth graduates, is 'not structured like the market world' — it operates by a completely different set of rules. In the market, input leads to output, effort leads to reward. In the moral world, 'you have to give to receive, you have to surrender to something outside yourself to gain strength within yourself.' This passage connected to Brooks's distinction between 'resume virtues' and 'eulogy virtues' from his book. Resume virtues are the ones that make you good at your job; eulogy virtues are the moral qualities people mention after you die. 'We all know that the eulogy virtues are more important,' Brooks said, 'but we live in a society that puts a lot more emphasis on how to build skills than how to build character.' By 2015, Brooks had refined the idea further. He told the Dartmouth audience that he had come to see commitment-making itself as the path to character. 'Becoming a good, moral person is not being able to control your temptations,' he said. 'It's about this ability to make commitments.'
