** bringing those things in harmony, the constitution, the legislation, and the law, is a really hard, collective problem.

Roberts:
* problem of the found wallet
* problem of the found wallet
* What does economics predict?
* What does economics predict?
** keep it and spend the money = "high level of utility"
or
** return the wallet so you don't feel guilty
** = example of putting morality into the objective function, into the preferences.
* Do I want to raise my children to not feel guilty?
Munger:
*  Suppose it actually is really expensive or difficult for me to find a person.
** What on the margin that'll make it less likely because demand curve slope down.
** Now, I don't know what the level is, but at the margin, it'll make it less likely.
* suppose that I really and probably cannot get caught and there's $10 in it.
** Then I'm probably going to return it.
** Suppose there's $1000? Suppose there's $10 million in it?
** Is there a price where anyone, literally anyone would not return the wallet?
** It's just that they differ about what price that is?
** Is there a different level at which all of us would say: This is so much money, I'm keeping it.
Roberts:
* Demand slopes downward.
** Or, it might be to save the life of a child, like Jean Valjean stealing a loaf of bread.
** You know, it's: We all have our price.
* And yet, when you tell that to people who aren't economists, they find it deeply offensive.
* in economics, we have a term for this: lexicographic preferences.
** It means I have certain things I take care of regardless of price.
Munger:
* E.O. Wilson, the famous entomologist says that we should understand biology, at least, evolutionary biology as a contest between two forces.
** First, any selfish individual will always dominate any altruistic individual.
*** So, you could call it altruism. You could call it morality. It's a big drawback for the individual.
*** if we only were individuals, then the selfish individuals might very well out-compete the altruistic individuals and they wouldn't exist.
** Second, groups of altruistic individuals will always dominate groups of selfish individuals, because we care about each other.
*** And it's not just that we are militarily better.
*** We are better in society; we're happier; we reproduce more; we're more economically active;
*** we're able to trust each other; contracting costs are less.
** any society has this tension between individual and group domination.
* small groups, 150 people have constraint on each other's behaviors
* larger groups do not, the sociopath can hide among 1 million people
* Rule Utilitarianism
** we have is a set of rules and habits.
** there's actually just a few little sets of rules that we can choose among.
** If you choose the one that's the best on average, sure, sometimes you end up paying costs,
*** but you actually become invested in the rule that you've selected.
Roberts:
* the Pandora's box of discretion
** you find yourself erring, making mistakes, doing what's self-interested, harming your reputation, doing things you're ashamed of.
** self-constraint, of tying yourself to the mast, an Odysseus-like method of giving up freedom, of giving up the discretion in this any one case
** you sacrifice some well-being, on average, because you know that the alternative is actually much worse
Munger:
* David Schmidtz book "The Elements of Justice"
** Having discretion means that you're going to get a bunch of rent-seeking contests where people know that the better argument they come up with
*** they're going to be able to win, when it's unlikely that the weak are going to win those contests. It's going to be unjust anyway.
** And the second is that it's just a giant waste of time.
*** You're actually better on average doing the thing that seems not as good.
* Aristotle talks about cultivating a character in exactly those terms
