Trivers, pursuing his theory of the emotions to its logical conclusion, notes that in a world of walking lie detectors the best strategy is to believe your own lies. You can’t leak your hidden intentions if you don’t think they are your intentions. According to his theory of self-deception, the conscious mind sometimes hides the truth from itself the better to hide it from others. But the truth is useful, so it should be registered somewhere in the mind, walled off from the parts that interact with other people.
In our world, that’s the way you live your grown-up life: you must constantly rebuild your identity as an adult, the way it’s been put together it is wobbly, ephemeral, and fragile, it cloaks despair and, when you’re alone in front of the mirror, it tells you the lies you need to believe. For Papa, the newspaper and the coffee are magic wands that transform him into an important man. Like a pumpkin into a coach.
You can repeat [the] lies of others without hesitation because you don’t have to give justification. But saying truth you have to be fearless and courageous because you have to defend your views. You cannot say truth without hurting [the] sentiments of many people.
If the Great Way perishes there will be morality and duty. When cleverness and knowledge arise great lies will flourish. When relatives fall out with one another there will be filial duty and love. When states are in confusion there will be faithful servants.
