By being kind to yourself, by respecting yourself, you won’t have the need to prove to others how ‘good’ you are by demeaning yourself in any way. True satisfaction of doing good comes from a conscious choice to do good, not from being coerced into it.
Scientists ideally approach a subject from a neutral viewpoint, without emotional pay-off for either the confirmation or the falsification of a hypothesis. The true utility of research is to discover the truth, not to be right. But we ordinary people also sometimes have to choose between getting wiser, and hanging on to an existing belief. If we really want to pursue wisdom, then we must leave behind the idea that giving up a belief comes at an emotional cost. We have to accept that it is a good thing to lose one’s beliefs.
