Should my posts ever seem to contradict each other you have two choices: believe the most recent post, or think about it yourself. You can apply the same options when I seem to be mistaken, if you like. The most recent post then would refer to the one you are reading and think is dumb, since it's the only one in the relevant set.

TCS does have some constant points, which I alluded to in saying there is a present day group of people who are identifiably "TCS". Should they give up the constant points, they'd probably think they should give up the name too.

But the constant points are not, as I also mentioned, the sort of things you'd expect. There are no prescribed behaviors. Common debates on the TCS email list include the merits of TV, ice cream, no bed times, and home schooling. But if we turn out to be wrong and TV really is harmful that won't make TCS wrong. The TV thing is just our best ideas about TV, not a necessary part of TCS.

The more constant things are much more abstract. TCS says that morality is a type of knowledge and that the same laws of epistemology (study of knowledge) which apply to knowledge in general also apply to moral knowledge. It is also committed to parenting according to rational principles and not, say, parochial ageism -- this is part of a general commitment to *living* rationally. TCS is also generally committed to the idea that the laws of epistemology are Popperian (roughly: evolutionary).

None of these things are especially about children or parenting. But TCS is about how they apply to parenting. When we apply them we reach conclusions like TV being good. We might have applied them wrong. Maybe they are true and TV is bad. That'd be our mistake but not any fault of TCS's core ideas.

I'd like here to say something like, "so, for example, if X was true, then TCS could be essentially given up on. the world would not be the way we think it is. it'd be like y." but the problem is there are no rival theories to Popperian epistemology which make even the slightest bit of sense. I don't mean to express any sort of certainty that Popperian epistemology is correct. it's just there aren't any respectable rivals today. i think we're lucky to have one sensible theory -- 100 years ago we had zero (well we had the beginnings).

let's talk about disobedient children now and ways of exercising authority.

hitting people is good for obedience. it has its flaws -- they might disobey when they think you won't find out. but essentially it is effective. people don't like being hit. they will go to a lot of trouble to avoid it.

the standard theme in parenting advice, historically, has been if you hit your kids early they become obedient quickly and you don't have to hit them very many times.

recently hitting has been confined largely to spanking. people say two different things about spanking. one is that it helps improve obedience, even if you only do it once or twice. well they usually don't put it quite like that. they might say it improves behavior. but they are judging the improved behavior in terms of which behaviors the parent finds pleasing. so that means good behavior consists of obedience to the parents wishes. the second thing they say is spanking your kid just a few times isn't cruel. if he's very young he will hardly remember later. it's just a very temporary pain. no big deal. but the behavioral improvements will be lasting.

this is kind of contradictory. how can the behavior improvements last if the fear does not?

i think what happens is the fear becomes less explicit. child isn't thinking to himself all the time "if i better do X or i'll get spanked". he doesn't verbally complain about spankings. but he is in the habit of obedience and has vague fears of doing otherwise. of course parents do many things to encourage this. vague threats are very common. "you better not do X". why not? what, exactly, will parent do if you disobey? almost all parental commands are backed up, implicitly, by some threat of force, but it's vague what it will be, and it frequently does not come to that.

other force parents use is time outs. these are supposed to be more humane than hitting children. as i understand it they originated as a "time out from love and affection" essentially. they are absolutely a tool for controlling and manipulating children. if you notice your kid really values your kindness, affection, warmness, etc, then you just take it away when he doesn't do what you want. sigh.

now let's stop and think a moment. these sorts of use of force are common expressions of authority. we sort of take for granted they actually have something to do with authority. but do they? parents aren't able to hit their kids due to parental wisdom. it's b/c the parent is bigger. how is the authority of a parent's intelligence being shown or used in any sort of punishment of discipline?

maybe a parent could claim that he uses his great wisdom to decide which punishments will be good. ok but good for what? the options are:

- obedience
- education
- other types of good things in the child's life such as not being arrested or killed

as i mentioned punishments are pretty good for causing obedience. but that's bad! obedience isn't a rational way of life. it presupposes the parent is right. it doesn't allow for making mistakes and learning from them. it doesn't allow for discussion, questioning, and criticism.

how does obedience function, really? well say parent wants child to eat more carrots, and child thinks they taste bad. well, then child has to eat them. never do they communicate about how important the reason to eat carrots is and compare that to how important the dislike of carrot flavor is. how can the parent know he's right without such a comparison? he doesn't know how they taste to the child -- he doesn't know what it's like to eat them. the only way to really figure out what's best is to communicate about the issues so one person can understand the points on both sides and compare. i'm not saying if you do that you are guaranteed to find a good answer, i'm just saying if you don't do that you can't possibly find a good answer except by pure dumb luck.

what about education? are punishments educational? parents often say, "go sit over there and *think about what you did*".

well the first thing to consider is if punishments are educational *in general* then shouldn't we use them with adults too? you and I should wish to be punished in educational ways. stop reading this and go have a time out. pretty silly concept, isn't it? adults don't learn by being ordered about and made to suffer. they learn from good explanations and from choosing to reflect on things. also from practice and such.

so if punishments are obviously no educational with adults why should they educate children? what on earth is it that not only makes suffering educational but makes it only educational for young, small, weak people who just happen to have parents who want obedience?

while there may be a good answer to that, it certainly isn't a well known part of modern thought. if we don't have the answer *already* then all that punishing of children can't possibly be justified by a rational expectation of it being educational.

as far as keeping the child from dying and such, that is essentially an attempted justification for making children obedient. then you can order them not to drink sweet sweet draino and they will obey. if we are going to claim making children obedient is good then fine, but let's be clear about what we are doing.

obedient children is not the best way to keep them safe. as i mentioned earlier, they won't obey when they think they won't be caught. and they won't obey any more when they grow up. the only thing, ultimately, that can keep people safe is knowledge of dangers. and the best way to have a child with a lot of knowledge is absolutely not to expect obedience. it is to have an attitude of being open to discussion and debate. people learn far more when they can discuss the merits of things and ask for your reasons and have their own reasons taken seriously and be given criticism of them.

it may be hard to recognize, in modern society, the sort of obedience that is expected of children and is common. many old types are fading. chores are only a remnant of what they once were. fathers no longer choose the husband of their daughter and take it for granted that she will go along with it (and will also obey her husband once married. sigh. stupid past.)

what do parents want today? well they say things like they want a good kid. they probably want good grades, or at least respectable. they probably want to keep him safe, which means to them things like having a curfew and not letting him be friends with bad influences who might do drugs or get drunk or something. some want polite, "respectful" children. parents want their children's love. most want to be called "mom" or something else which is not their first name. most want their child to go to school. and they want him to succeed in a career and "be happy".

all of this sounds sort of pleasant when you say it like this. they are trying to look out for their kids, and help them, aren't they? well, each of these things is a potential for disagreement, and a potential place a parent might want obedience without having to defend his view in debate (which, perhaps, he cannot do).

a good kid -- good natured, fun loving, happy, well rounded, and many more positive traits -- means a child who agrees with certain values. when a child is not "good" there are two possibilities. one is that he's making mistakes while trying to do it. but in that case obedience is useless b/c even if you order him to be good what difference will it make? he's already trying and just doesn't know how. the other possibility is there is something about being "good" that he doesn't like or want, so he's avoiding it on purpose. why would that be? well the conception of a "good" kid people have is very complex and detailed -- there's a lot there. plenty of room for differences of opinion. especially if there are no open discussions to clear up misunderstandings and give reasons which is how you can rationally reduce differences of opinion by coming to agree. so if there is a difference of opinion child might seem "bad" in parents eyes -- he keeps not doing as expected and as parent thinks is best. parent might be frustrated and then think his child isn't listening and then want obedience (he might not even think of it as obedience, but you can see how he could unconsciously want something like that).

what about grades? well we all know a lot of people don't like school and find it unpleasant and aren't learning much. also a lot of teachers aren't very good, and sometimes are arbitrary, capricious, and unfair. getting good grades in every class might not be best. especially if child isn't very interested in what that class is teaching. so again we find room for a parent to want obedience, and to think to himself he's just helping his child, when really he might be fighting to make his child do something which isn't best. the rational thing isn't to assume of the child is right, of course, it is to seek the truth of who is right. and that has to be done without any use of authority. if you're such an expert just say and think wise things and you'll both find the truth faster, whatever it is.

what about keeping kid "safe"? well basic things tend to be easy to agree on. people rarely fight over whether it's ok to tie yourself to a stake and light a bonfire. common issues are more like curfews where it is not at all obvious to child that there is any serious danger of anything more than fun. or maybe "danger" of alcohol -- but to child that isn't a danger b/c no one will force him to drink he will only drink if he chooses to. (yes i know child may be pressured to drink but it is ultimately his decision and he also chose to have those friends b/c he thinks it is best). whether there are safety concerns or not there is easily room for a parent to want obedience here after he finds it hard to persuade his child.

being polite is a specific case of the issue of being conventional. most people are conventional, and don't see how life could be otherwise, and condemn other ways of life. children who haven't had a given convention entrenched in their mind often won't want to obey it. this causes disputes with parents. conventions tend to be short on good reasons, so parents are very tempted to want obedience even if they can't give good reasons.

i may be wrong about politeness. maybe it has more merit than i see. and certainly i don't advocate complete rudeness. i just think a fair amount of politeness is unnecessary waste of time and energy. but anyway the point isn't really whether i'm right or wrong about any particular convention, nor whether it's good or bad. the point is the logic of the situation tempts parents to desire obedience. and the rational thing to do capable of discovering the truth of what is right is not obedience. obedience never ever finds the truth. how could it?

ok enough examples you get the idea. there are lots of temptations for obedience today. so any sort of punishments don't find the truth, and don't seem to be educational with adults. and how could they be educational? sitting in the corner is rather different than reading a math book. while sitting there you might think of a good idea. but the corner isn't going to tell you one. when you are hit again the hitting doesn't tell you any good ideas. it just pressures you to come up with ideas about how to please the people hitting you so they stop -- obedience.

another type of punishment is various types of "consequences". if you get up late you have to walk to school. if you stay up too late playing video games you can't watch TV for a week. if you lie to your parent you can't see your friends for a month.

sometimes they are "natural" consequences which are supposed to be justified by being natural parts of the action, but which in fact can easily be avoided by parenting choosing to avoid them.

these consequences are sort of manipulative. you get child to relate waking up late and having to walk, for example. but those don't really have anything to do with each other. it's a very weird life where these arbitrary things are tied together.

and they are clearly punishments. they are things the child doesn't want, and which the parent just does to him to make him suffer and to make him obedient. how do we know it's for obedience? well parent wants thing 1 so he threatens thing 2. these consequences are never about convincing. they aren't reasons thing 1 is best. they are just threats of the nasty stuff parent will do if child doesn't do what parent wants done.

and they are clearly not educational. say waking up early has merit but child doesn't see this. how is threatening him with walking around going to show him the merit? it isn't an explanation of the merit.

we could claim that child might learn the merits himself by trying it, and the point is just to get him to try it. in fact that must happen sometimes. but is threats the best way to get child to try something? won't he learn more easily if he's going into it with an open mind trying to learn?

of course if child would try it just because he was asked that would probably happen. so issue number one is parent either can't give any reasons it's probably worth trying or he just doesn't want to bother b/c he's used to obedience and finds that easier (it means he has to think less). that's no way to find the truth. maybe the reasons are hard to give because there aren't any. and issue number two is if child doesn't want to try it that is because child sees benefits to something else. if you threaten him and make him obey you are taking away those benefits that he believes the alternative has. you are depriving him of the good things he believes his preferred lifestyle has. and how do you know you are right to do that? the only way to get a good sense is to have an open discussion and communicate the merits of each approach and compare to see which is better. if you try to do that you still might not agree -- which is evidence that either it's hard to see the answer (so you shouldn't be so sure of yourself) or someone is being irrational (which could be you, so again don't be so sure of yourself. i know you're saying it's not you. but imagine if you did have an irrational idea in you. you'd probably still say you didn't, right? because they usually make you blind to their presence.) the bottom line is anything that doesn't communicate the rival ideas and compare them -- such as threats of consequences -- can't possibly be a good way of seeking and finding the truth of the matter of what is best. and if you aren't striving to find what's best, aren't you in a really poor position to be demanding obedience?

Taking Children Seriously (TCS) is a philosophy of parenting and education. But it's bad to label it. It isn't one set of opinions that you may or may not agree with. It isn't meant to be a particular school of thought or camp. Other parenting labels advocate specific actions and are tied to those actions. Attachment Parenting wants more parent/child touching, co-sleeping, babies in slings, and things like that. It's a set of ideas you might agree with, and might disagree with. Homeschooling is about taking kids out of school. If your kids go to school you aren't a homeschooler, even if it is morally right that your kids go to school -- perhaps because they want to for a good, thought out reason.

TCS isn't about doing a specific thing and if it's right to do something else you must give up on TCS. It's a different sort of thing. TCS is a set of ideas about what *is* right. If we were to change our mind about what was right, we'd also change our mind about what TCS is. That means it can't turn out to be wrong, at least in the long run, because it will change. No valid criticism of TCS can stay true over time because TCS will change so that is no longer a valid criticism of it.

This all sounds a bit unfair. Like TCS is cheating because it wants to win no matter what. And that gets back to the original point: labeling it is misleading. No one thinks it is unfair that our best ideas of parenting should be continually updated. The only thing that's unfair is calling the best ideas TCS, saying we invented it (or that Sarah did), and trying to take credit for "TCS" even as it changes.

But, there really is a distinct set of good ideas about parenting, which are unpopular or unknown in general, and which are advocated by the TCS movement. The present state of those ideas certainly has flaws and will be superseded. But, at present, it is important, and it's hard to refer to otherwise.

Anyway, this is all about terminology, and a bit dull. The important thing is: what *are* the best ideas of parenting and education that we know of? And we might also wonder why they aren't very popular, and what is the history of the presently dominant parenting ideas, and other fun things like that.

First I want to say that some good parenting ideas are popular. I respect the progress that has been made. We take for granted, today, in the USA, that we should buy things that our children want, and help them to learn, and help them to be happy, and help them to become independent. Each of those has some limits placed on it, but still those are great things. Think of what are goals are *not*. We do not spend all our time teaching conformity and obedience (although parents do expect a certain amount of obedience and discipline, and often encourage conformity, sometimes unintentionally). We do not approve of forcing children to work for our benefit (chores being only a minor exception). We do not, generally, decide what our child should (must) be, and his place in life, independent of his wishes, and force it upon him. We do not foist arranged marriages on our children. We don't mutilate female genitalia.

One thing that is helpful to know about these new and (I claim) better parenting ideas is that many are not full descriptions of how to live. And this also relates back to, above, why TCS does not prescribe particular behaviors and link itself to them. TCS is more about suggested policies of behavior, and it is up to you to decide which particular actions are appropriate within the bounds of the general policies which are right. And it also has many criticisms of present day behaviors, often with no particular alternative given. If this sounds a bit unhelpful, don't worry. There is ample advice about how to think such that you come up with great ideas, and there are explanations of why no alternatives to many parenting practices are needed.

Thanks for bearing with me so long. One of the problems is it is difficult to figure out where to start. There is a big picture, but when you talk about it then it sounds a bit like boasting. But if you talk about the fine details it may not be clear why they are important.

So, let's consider punishment, aka "discipline". Parents generally make some rules, set some limits, some boundaries. And they make requests to their children, and expect certain attitudes like politeness and a degree of obedience. Sometimes this is hidden. Parents often will tell a child it is bad to do a certain thing, and that he must do something else. They expect obedience and become very frustrated if child does not comply. It seems to them child is being intentionally wicked and is a trouble maker. It is good to have reasons for parental commands, such as an appeal to morality, but that doesn't make them any less of commands.

There are two major issues here so let's try to separate them. One is the obedience itself. It's the idea of parental authority -- a legitimate right to command the ignorant child. The other issue is what do parents do if their child is disobedient. They discipline or punish him. Sometimes they plead, or try to make him feel guilty, or other unpleasant things. Those things are designed to control the behavior of the child just as much as a punishment is.

So, authority. Why should a parent have authority? Well, maybe because he knows more. Compared to a young child, a parent is an expert at most stuff. There is really a big difference. Another possible justification is that the parent is bigger and stronger -- he can use force. This is not a good reason, but it's worth mentioning and rejecting because the idea comes up sometimes. Consider a time out. The justification might be that the parent is smarter, wiser, and therefore correct and the child needs to learn to do the thing the parent knows is right. But whatever we might think of that, the form a time out takes is forcing a child to sit in his room or in the corner. So the form of the authority -- force -- does not match the claimed justification very well. If the thing that sets parent and child apart is intelligence then why is the parent using force instead of his mind? Why doesn't he best the disobedience child with rhetoric? With criticism of child's actions? With powerful, undeniable good reasons? People will say it is because the child does not listen. But first, punishing child is a very poor way to make them listen. It turns them against you because it hurts them, which is its purpose. And second, children do listen sometimes, especially when they think you're being helpful. If you're so much smarter and wiser, and especially if you have great knowledge of the issue child is being punished regarding, then that is all the more reason you should be able to talk so child will want to listen, because you have such good things to say.

Authority is never a valid way to argue, you know. Just because I have this fancy blog doesn't make me right. People with college degrees make mistakes. Kings too. Priests too. Experts of all sorts are wrong sometimes. We all know this. If you say you're right because you have authority, so listen to me, you're just being a jerk. You can't say that to people. What you need to do is give a reason you are right -- and one the other person can understand. If you can't give one they can understand -- maybe you say it's too complicated -- then why would they listen to you? A real expert would be so good at his field he could give a summary. It might be missing a lot of details, but it's something.

This is important stuff. If your car mechanic says "I'm a mechanic and I know best" you wouldn't trust him. You don't to find a better mechanic who will treat you like a thinking person and explain his recommendation, and then let you make the final decision if you want the expensive stuff he suggests.

If your college professor makes a claim about a philosopher that you don't agree with, and he says he's right because he's the professor, that's a bad teacher. You shouldn't listen to him. Do your own research and make up your own mind. A good professor with a good point would convince you he was right.

There's one exception. Parents don't have to give reasons. "Because I said so." is an approved sentence. It was even featured in marketing by Apple Computer, which demonstrates that it doesn't offend a significant amount of people. There's a movie by the name now, too.

Because You Said So
More flexible parental controls in Leopard mean you can place restrictions on use of the Internet. You can, say, specify a time of day and duration for your child to play World of Warcraft.

This isn't just rejoicing in taking choices away from children and putting them in the hands of their parents. It isn't just about having power over your child's life. It's also about *not having a reason*. You don't have to give reasons, you just set it up and that's it. You said that's how it will be, so that's how it will be.

That's authority. It's bad. What we should aim for is a life governed by reason. Part of living according to reason -- according to thinking about what is best and why and trying to find the truth of things -- is having reasons for things! And discussing them. If someone disagrees, even a child, you can't just assume you are right. You need to hear their reason and think about it. Maybe it's valid. Maybe not. If you can say why it's wrong that's fine. But then you've given a reason. And if you can't, that doesn't mean you're wrong, but you shouldn't be certain who's right if you can't say what's wrong with the alternative.

Children know a lot less. That doesn't mean they are always wrong though. The times they speak up about something are usually the times they know the most about something! It's not what they know on average that's important but what they know about the specific thing at issue. Say the issue is when they play World of Warcraft. That's actually something they would know a lot about. They know their own schedule pretty well. They know how tired they are and whether they want to go to sleep yet. A parent can have a different opinion about one of these things -- and be right -- but it's no where near guaranteed. If you just block all World of Warcraft after 10pm that's not a very good policy. It's going to make a mistake. One saturday night child is going to be playing with a group of 39 other people completing a major quest and he'll be wide awake, and he'll have no important things to do the next morning, and he'll want to play longer and not abandon those real live people he's playing with. And then the apple software is going to kick him off the internet whether it's right or wrong, and it's not going to give any reason.

Sometimes children think they know enough to have an opinion when they really don't. But that's not so hard to deal with. If you help them figure out how to tell if they know enough -- and how to learn enough -- to have good opinions that is genuinely useful advice and there's every reason they will want to know that and listen (unless they think it's a mean trick to control them more, of course). But besides that, the argument can still proceed rationally even if they are mistaken about how much they know. It's really not a problem. If they don't know enough just ask them some questions about their position and they won't have the answers because they don't know. Problem solved. They'll see their ignorance when they can't answer.

A lot of times children don't want to do as they are told because they think they won't like it. That, again, is absolutely no time for a parent to put his foot down or rely on authority. If child thinks he won't like something out of ignorance just tell him a little about it focussing on the fun and enjoyable parts.

You might think all this explaining things to children is a waste of time. Well, not a total waste because it's educational. But how important is it, really? What if you're tired and don't feel like it right now? If you know you're right, what does it matter if you don't give your child a lesson about the reasons every time?

The answer in very short is that you might be mistaken. Don't take it personally. Everyone is mistaken sometimes. But it's more than that. The process of giving reasons is actually a part of how we can avoid mistakes. The more you know, and the more right you are, the easier it is to give reasons. But the less you know, and if you are wrong, then it's much harder to give reasons or arguments or to persuade anyone. So the times when you most feel like giving reasons is too much trouble are actually hints that those are the times you are most likely to be wrong or at least not to have thought it out carefully.

So part of the concept of authority is obedience. That's what the child is supposed to do. The authority gives a command, and the child obeys. Obedience is kinda mindless. It's not about considering if the command is a good idea. It's just about doing it. That's not a good habit to be in. It won't serve you well in life. And even if it would, is that really the kind of life you want for your children? We rightly value lives of thinking and reason where we make a lot of our own decisions and we can pursue happiness according to our own values. The idea with children is they can do that when they are older. But isn't it strange to live one way and then suddenly change later? If thinking is so great why not start young? Very talented people usually do. It's kind of well known that young kids sometimes learn really fast. Other times people say young kids don't have fully developed brains. But that's a load of crap. English is very complex and they figured that out.

Thinking isn't important just to get in the habit. You learn more when you think things out. And that dispels ignorance. And ignorance is the justification for authority over kids in the first place. By expecting obedience you take away opportunities for them to grow up, essentially. Even making mistakes is important to people's learning process. Most mistakes have no serious lasting harm so don't worry about it so much. Say child stays up late *and it was a mistake*. Who cares? Next time it will be even easier to persuade him to go to bed -- if he doesn't want that on his own! -- because of the bad experience. Being able to try out your own ideas is important. Discussion is great but sometimes people find this or that thing hard to understand just from words and it'd help to experience it.

Obedience also is about not questioning or criticizing authority. But questions are a great thing. They help people to learn and understand better. People don't ask enough questions. And criticism is good too. It's a chance for you to learn your mistake. Or if you think the criticism is wrong it's a chance for you to point out a mistake in the criticism and then the criticizer can learn. In general, criticism helps find good ideas because they stand up to it best. And it helps get rid of bad ones because they can't stand up to it very well. With no criticism you can't really tell the difference between good and bad ideas because you aren't looking to see what's wrong with any of the ideas.

As a reminder, the other major issue we were keeping separate earlier was about what you do to a disobedient child -- how you exercise and enforce your authority. I'm stopping here. I might write about that tomorrow.

so i'm in the security line at airport. this guy was repeatedly announcing to the whole line that you can't have liquids or gels except in tiny containers in ziplock bags. i have some shampoo but i don't have a bag so i go up to ask where to get one. he ignores me, i say "excuse me" a few times, and finally he turns to me, so i ask. he says i interrupted his conversation with the line and now he won't tell me where bags are.

so i just put my shampoo through without a bag, and they don't notice it. they do notice my bottle of water. it's just so strange to ban water that it slipped my mind (i'm no chemist. maybe it's a justified security measure. but it is strange to live in a world where water is a security issue). i asked if they could pour it out and give me the bottle back, but the guy just walked off without a word. i waited a while and fortunately he came back with my bottle. he put it through the scanner, empty. i guess you can never be too careful with clear plastic bottles. he didn't say anything so i asked if i could go now, and i could.

for the flight back i brought a ziplock bag. unfortunately that meant they noticed my shampoo, and then threw it away for being too large (6 oz bottle not 3.4 oz.). it was only half full.

gameshow w/ 3 doors. 2 have goats. one has prize. u pick one. host opens a door u didn't pick to reveal a goat. then u can switch doors or not. what to do?

this is a well known problem. and the answer is:

**************** (answer below) ******************

the answer is switch, which gives u 2/3 odds. staying has 1/3.

why is it interesting? b/c a lot of ppl get it wrong. and *still* get it wrong after being told the answer. you can show them a chart with every possible initial setup and every choice you can make, and the results come out just as I said the answer is. but still some people think it's 50/50. including many mathematicians. according to my book on Erdos, this problem first got popular when the correct answer was given in a column, and 90% of the mail said she'd gotten it wrong, including from professional statisticians and such. a lot of the mail was angry. even Erdos (famous, brilliant mathematician) had trouble with it.

this is all very strange. the problem seems, to me, quite simple. lots of explanations have been given. here is mine that I think may get at the heart of why people are confused:

they think: there are 2 doors left it could be in, so it's 50/50. but lets look more closely at the part where the host reveals a door to you. what he's saying is IF your initial guess was wrong (which we know is 2/3 likely) THEN you should not pick this door here, b/c it has a goat. so he's telling you which one to pick (if your first guess was wrong). if your first guess was wrong, you now have a 100% chance when you switch doors, b/c you know which of the two has it. so you should switch banking on the fact your first guess is probably (2/3 likely) wrong, since you made it blindly from from 3 doors.

i got a book on Paul Erdos who devoted his life to math and wrote > 1000 papers (most ever i think) including with 485 different co-authors.

he put off an operation for cataracts for years because the week of recovery time would prevent him doing math.

erdos put out rewards on math problems he failed to solve. he put out rewards on over a hundred problems for more money (in total) than he had.

the reason he had no money is he gave it all away. he didn't even have a home. he just travelled around and stayed with mathematicians, solved a problem with them, and moved on.

since it was before the time of email, he sent 1500 letters a year.

here is the part that is strikingly similar to some plot from House:

his friend once thought he was addicted to drugs. he took amphetamines (stimulants) all the time. they bet $500 about him going without for a month. he did it. then he said: without the stimulants i had no good ideas. you've set math back a month. and he started taking them heavily again and being productive again.

sometimes people strongly want drugs, take them a lot, and strongly protest any reductions ... and are not addicted, their *reason* tells them to do this.

even if House is physically addicted (ie he'd get withdrawal symptoms) that doesn't mean he's mentally addicted (*irrational* need for the drugs). and just b/c he resists quitting his pain killers, or taking any less, does not make him an addict. as he says, he's in pain, and the drugs help him do his job.

Public library policy: no drinks. Period. Not even in your bag.

Barnes and Noble's policy: sure, drink a smoothie, no one will say anything.

The book store faces competition which gives it an incentive to find the right policies. Further, it highly prioritizes letting customers do whatever they want so that they will be happy. To continue to exist a book store must sell a lot of books to satisfied customers.

The government libraries have a different incentive structure. They don't need to make a profit, or be run efficiently. To continue to exist a library ultimately must answer to voters (and only indirectly via electing politicians who have different library policies), not its actual users.

Further, and this should be no surprise, the library policy is part of a general attitude by the government that it should make rules to force people to do what the rule-makers see is best. And, as is frequently the case, the government is doing a poor job with its rules. Private book stores function just fine without banning drinks.

I finished reading Caleb Williams by William Godwin today. It's a novel that came out about a year after Political Justice and was aimed more towards common people with both a much lower price and also a less intellectual style.

The main themes are how unfair the criminal justice system can be, and how the rich have power to hurt others. The main character and narrator, Caleb, is falsely accused of a crime by an angry gentleman, Mr Falkland (a murderer), and spends over 270 days in jail in awful conditions before his trial. During this time he is badly mistreated including having a manacle very painfully put on his swollen, twisted ankle and having the straw for his bedding taken away in case he might conceal something in it.

Caleb escapes from jail, but never escapes from Falkland's power. He's tracked down and everywhere he goes his reputation is ruined and the threat of prison looms over him. Later he is acquitted at his trial but Falkland continues to harass him. Falkland hires a man to track him down wherever he goes, and also to assault him if he tries to set sail for a foreign country. Being innocent does Caleb little good as he feels from place to place and the people he meets turn against him, often without even being willing to listen to his side of the story.

The kindest characters to Caleb are a band of thieves who have a sense of honor and expel one of their own for assaulting Caleb (this brutal former thief is the man Falkland later hires to track Caleb).
