Consciousness Explained

Whenever I read Darwinians and atheists, I find myself in agreement with their arguments. As Galileo said, the role of religion should be to determine how to go to heaven and not how the heavens go. Put differently (and in a way that doesn’t presume there is a heaven), only critical thinking will help us discern the nature of reality so that we can base our conduct on actuality rather than fantasy, but the question of values and how we should behave is separate from that.

What I cannot understand is the Darwinians’ and atheists’ confusion about consciousness, a problem that B. F. Skinner solved 75 years ago. What is especially perplexing is the fact that Skinner’s account of consciousness is a perfect analogy to the Darwinian account of life. I don’t know why E.O. Wilson calls Skinner (but not Darwin) a “greedy reductionist” for believing that all operant behavior evolves under contingencies of what works just as anatomy, physiology, and instinctive behavior evolve under contingencies of survival and reproduction.

Skinner called his behaviorism “radical,” (i.e., thorough or complete) because he rejected then-behaviorism’s lack of interest in private events. Just as Galileo insisted that the laws of physics would apply in the sky just as much as on the ground, Skinner insisted that the laws of psychology would apply just as much to the psychologist’s inner life as to the rat’s observable life.

Consciousness has nothing to do with the so-called and now-solved philosophical problem of mind-body duality, or in current terms, how the physical brain can give rise to immaterial thought. The answer to this pseudo-problem is that even though thought seems to be immaterial, it is not. Thought is no more immaterial than sound, light, or odor. Even educated people used to believe, a long time ago, that these things were immaterial, but now we know that sound requires a material medium to transmit waves, light is made up of photons, and odor consists of molecules. Thus, hearing, seeing, and smelling are not immaterial activities, and there is nothing in so-called consciousness besides hearing, seeing, and smelling (and tasting and feeling). Once you learn how to see and hear things that are there, you can also see and hear things that are not there, just as you can kick a ball that is not there once you have learned to kick a ball that is there. Engaging in the behavior of seeing and hearing things that are not there is called imagination. Its survival value is obvious, since it allows trial and error learning in the safe space of imagination. There is nothing in so-called consciousness that is not some version of the five senses operating on their own. Once you have learned to hear words spoken in a way that makes sense, you can have thoughts; thinking is hearing yourself make language; it is verbal behavior and nothing more.

What would really be startling and, in turn, would make me question my scientific worldview would be if the mind were capable of doing even one thing that the senses can’t. If we could, for example, smell things in our imagination even though our bodies were incapable of smelling, that would change everything. If there were a sixth sense that was not merely an example of the five senses, I’d believe in a mind that was different from “private behavior.” But there isn’t.

In my imagination, you are disappointed by the simplicity of Skinner’s explanation of consciousness. You intuit something beyond or beneath hearing, seeing, etc., in your own consciousness. Your intuition is wrong, but your disappointment is real. I think one of the main reasons people resent science is that people think about complicated things long and hard, sometimes for centuries or millennia, and then science’s explanation is ludicrously simple. How the stars go? The earth is spinning. When the thing explained is you or something you care about, a simple explanation can irritate.

Zooming In and Out part 2 (Trayvon Martin)

I’m not writing about my main reactions to the verdict because I have nothing new to say about them. If it’s too soon for an intellectual reaction, don’t read this.

Zooming in and out can change a narrative by highlighting certain facts and putting others in the background or off the screen entirely. What George Zimmerman’s lawyer did, like Rodney King’s assailants’ lawyer, was change the zoom level. The focus was on the moment when teenaged Trayvon Martin was on top of George Zimmerman, a tight closeup on Zimmerman’s banged-up head and face. In that frame, it looked like shooting Martin was justified. How Martin and Zimmerman got to that point was left offscreen. Similarly, slow-motion replays of Rodney King trying to get up and thereby justifying the police’s use of force tightly framed the narrative as an interplay between a suspect’s refusal to lie still and the police response. This led to their acquittal.

Zoom out a little and it looks like an armed man followed an unarmed teenager and killed him. Zoom out a little further, and it looks like a race-motivated armed property owner followed and killed a black male. Who knows what he said to get Trayvon Martin so angry or frightened?

Many people, especially black people and others who identify with them, simply don’t believe that the jury weighed the relevant evidence and not the races of the parties. Or, if they did, and it’s the shooter’s subjective experience of fear that justifies an escalation to deadly force, then the case stands for a license to shoot people that make you nervous. Since many black people make many white people nervous, the verdict seems to be a license to shoot black people in Florida.

Suppose that Trayvon really did sit on Zimmerman’s chest, provoked somehow into banging Zimmerman’s head on the pavement. Suppose the cries for help really did come from Zimmerman. How is this different from the cops beating Rodney King? The white jury in that case was told, and believed, that King controlled the cops by refusing to lie still. Every movement of King’s justified the cops’ continued beating of him. Why doesn’t Trayvon get a free pass for beating a man who wouldn’t shut up and lie still?

Well, the answer of course is that Zimmerman is white (looks white, which is the exact same thing), while Trayvon looks black. But keeping the zoom at a level that includes only Zimmerman’s thoughts and feelings at the moment he drew his weapon ignores all that.

So if you zoom in to the same level used in the Rodney King defense, Zimmerman is responsible for whatever beating he received, as Rodney King was found to be. And if you zoom out to the level of common sense (armed white guy provokes a confrontation with an unarmed black teenager and kills him), Zimmerman is guilty. The prosecutors didn’t do as good a job as Zimmerman’s lawyer of controlling the zoom level.

On Being and Having a Wife–Bonnie Clark Guest Blog

On Being and Having a Wife
Bonnie J. Clark
July 13, 2013

On the eve of Independence Day, I woke up next to a woman who was not just my beloved, but also my wife. That I, too, was hers was evident by my new wedding ring and our two bouquets, slightly bruised from being tossed the previous day. My many emotions that morning—joy, love, victory, relief—were joined by a bit of the uncanny. Could we, after nearly 19 years as a couple, really be legally married? Did I really have a wife? Was I really someone else’s?

The short timeline to that morning began five days earlier in a magazine shop on Market Street in San Francisco. We were freshly off the plane from Colorado for a short trip to visit friends in California. As we browsed the periodicals, the radio crackled the news: they had resumed gay marriages at City Hall. We couldn’t quite believe what we heard. California’s Proposition 8 (along with the Defense of Marriage Act) had been overturned only two days earlier. Most everyone had predicted a 25 day wait, typical procedure for a Supreme Court ruling. But sometimes the wheels of justice turn quickly, greased by the work of many motivated individuals. Later that evening, a friend who had himself worked on the case filled us in on some of the legal details. These marriages, he reassured us over a celebratory cocktail, were going to stick.

The next morning I woke up at first light, too excited to go back to sleep. Why not turn our vacation into a wedding?, I asked my sleepy, defenseless partner. We had everything we needed: each other, a good friend to marry us and others to witness, and most importantly an open door for full, legal marriage. So, despite the fact that we had spent much of the flight the day before sketching out plans for an elopement to New York, we decided to wed on the Berkeley campus. It was a place that we, as Ph.D. students, had come to love and feel at home. The next three days’ whirlwind of planning, shopping, and logistics only added to the romance. But it wasn’t ours alone. Everywhere we went we encountered palpable excitement. Scores of couples and their supporters filled the Sonoma County Clerk’s Office the day we obtained our marriage license. A gallery of photographs from the Santa Rosa Press Democrat captures the spirit of that day, a historic moment when love and civil liberties were together victorious (http://www.pressdemocrat.com/gallery/gallery/701009998.html.)

But the longer timeline, as is likely true for many other couples who married that week, is significantly more complicated. When marriage equality nudged its way to the front of “the gay agenda,” I was ambivalent to say the least. Girls who grow up in Utah, as I did, feel the pressure to marry early. By my senior year of high school, bridal magazines were passed around the back of classrooms like pornography. My dreams were of college, not of hope chests or bridesmaids. Quite frankly I came out as a feminist long before I did as a lesbian. Add in that I am an anthropologist, and you can imagine my failure to see marriage as a clearly beneficent institution. The Titanic seemed to me a proper metaphor for marriage: Queers clamored to be let on board, somehow blind to the fact the vessel was visibly foundering.

An important turning point in my attitude came at a Denver rally in 2003. While celebrating a new city ordinance recognizing domestic partnerships, the crowd was reminded of the work ahead. The speaker, a straight ally and an African-American woman, told us to listen closely as she read from the majority decision in Loving v. Virginia, the 1967 Supreme Court decision that overturned anti-miscegenation laws. These are the lines she read:
The freedom to marry has long been recognized as one of the vital personal rights essential to the orderly pursuit of happiness by free men. Marriage is one of the “basic civil rights of man,” fundamental to our very existence and survival.

At that moment I knew she was right. A full citizen, a “free man,” gets to marry whom they choose. Until I had that freedom, my full personhood was denied. A more quotidian turning point came when my partner and I were struggling to keep up our household on my junior professor salary while she completed her dissertation. At tax time I compared my actual tax bill to what I would have paid had we been able to file jointly. Putting a dollar figure on discrimination only made it just that much more obvious.

So by the time DOMA and Prop 8 fell, I was ready. My commitment to my partner has never been in doubt, but coming to terms with the social meaning of marriage and especially expectations around “wifedom” has only begun. Will I use the term in conversation? It avoids the ambiguity of “partner” and the juvenile connotations of “girlfriend.” I like its political punch, but the few times I’ve tried it out in serious conversation, it’s tripped me up. Among friends its utterance is typically followed by something like, “Holy Shit! I have a wife.” When my partner calls me her wife, it doesn’t carry the baggage I expected, at least so far. It feels sweet, a term I am lucky to claim.

And I will continue to claim it although, technically speaking, in Colorado I don’t have a wife. Our California marriage will here, at least for now, be recognized as a civil union. But as my sister told me, “No, you are married. More married than those idiots on the Bachelorette.”

Bonnie J. Clark received her Ph.D. in Anthropology at the University of California, Berkeley with a Designated Emphasis in Women, Gender, and Sexuality in 2003. She remains wary of the wedding industry.

Egyptian democracy is not (just) about free elections

Senator John McCain, who should know better, recommended cessation of aid to Egypt, stating, “We cannot stand by without acting in cases where freely elected governments are unseated by the military arm of those nations.” The confusion has to do with what a democracy is. A democracy, to whom the United States should pledge allegiance, assistance, and fraternity, is not about freely elected governments. It is about protection of minorities. Any system of government will become totalitarian if minority views are not protected. The firmest protection of those views can be found in our First Amendment: religious freedom, free speech, free press, the right to assemble, and the right to complain.

No government, elected or appointed, without these elements, can escape tyranny. Indeed, Madison and Hamilton, in The Federalist Papers, teach us that a government in which the executive, judicial, and legislative functions are seated in the same group of people is the very definition of tyranny. What they mean is that a government that doesn’t have to answer to its minority views inevitably tramples those views and the persons who hold them.

Governments that embrace a particular religion must be right and dissenters must be wrong. If religion means anything, it means that. That is why I have called John 3:16 the most despicable verse in the Bible, because it says that belief (rather than good behavior) leads to salvation, and therefore it demonizes critical thinking, humor, and protest, the hallmarks of social justice. It’s the nature of religion that it cannot produce a constitution that protects minorities, because religion equates protection of minority viewpoints with deviltry. Only the separation of church and state, the foundational idea of our way of life, can lead to democracy. (It doesn’t automatically produce democracy of course, as any slave would testify; it is a necessary but not sufficient condition.)

This is why the philosophical basis of our democracy, set forth in the Declaration of Independence, emphasizes the proper role of government and its source of power. The role of government is not to control the people but to secure their rights. Government’s just source of power is not God but the consent of the governed.

Parent worship also produces totalitarianism within the individual. Psychotherapy can be viewed as a way of bringing First Amendment rights to the minority and marginalized voices within the person, so the patient can stop squelching herself.

If angry girls are told they’re tired, what are angry boys told?

Skinner said, late in life, that one of the humilities of old age was that, after having a good idea, he would realize that he’d already had that idea in 1953. One of my humilities is that, after having a good idea, I often recall that Skinner had that idea in 1953.

So the main point of my previous post wasn’t that many women think they’re tired when they’re angry; my main point was that you can only describe your emotions as you were taught to describe them by the people observing you (what Skinner calls the verbal community). Still, a commenter asked what I think is the boys’ analogy to tired girls.

Anger is the emotional state in which observing damage (to the object of one’s anger) operates as a reinforcer. Damage doesn’t have to mean a broken arm; it can mean a loss of face, a disappointment, or a look of concern.

I think many Americans are less upset by angry boys than by angry girls, so boys are more likely to learn that they are angry when they are angry. On the other hand, society’s relative comfort with boys being angry and with being angry at boys means that many boys don’t learn to disguise their anger, and they are therefore more likely to incur punishment for anger. This in turn makes boys more likely to avoid authority figures and to express anger when they are not being watched. Women are therefore more likely to comfort themselves with food and napping when angry, and to hurt people while acting manifestly within social norms, while men are more likely to avoid self-monitoring when angry and to express it in ways that breach social norms. Parents who recognize, accept, and manage their children’s anger produce adults who recognize, accept, and manage their own anger.

So, I’d say that many boys think they are bad when they are angry, but they recognize that they are angry. Other boys are taught that they are confused, and then they seek order through obsessive-compulsive behaviors when angry.

Boys are more likely to be mislabeled as tired when they want to snuggle. Tired or weak. Some men can snuggle only when they think they are tired. One of the many things I love about Janna is that when I come home at the end of the day and want soothing comfort, she provides it without metacommunicating that I should man up or stop complaining or, worst of all, take care of her. How did I go from purveying Southern machismo as a child to feeling comfortable with my own dependency needs? I’d say a lot of it had to do with the times I grew up in, with feminism to thank for redefining the role of men, and a lot of it had to do with my high school girlfriend, who tolerated my disgust with my desire for physical comfort without construing me as weak for wanting it. If your first love was someone who genuinely liked you, you are blessed. Last love, too.

Zooming In and Out

The maps on my computer and phone tell a different story depending on how far in or out you zoom. At the closest level, the story is about the state of the yardwork around my house (somebody should trim that overgrown bush in the front yard). Then there’s a story about what a cool neighborhood I live in, surrounded by restaurants and retail. Then there’s a story about how far my commute is, and a story about the pioneers who settled down when they got to the mountains even though there is no navigable waterway, and then a story about how far away the ocean is. You get the idea.

People narrate events in a way that, without their knowing it, supports their happiness or unhappiness, that supports their sense that things are going well or badly. (Happiness when things are actually going badly is an opiate that keeps you from improving things; unhappiness when things are actually going well keeps you from enjoying things.) When it comes to unhappiness, psychotherapy can be construed as changing the narrative to one that remains true to reality but connotes a different meaning. One way to think about that narration is to consider the zoom level patients are using, rather than just to consider what they are making of the different events. (Zoom can be considered an example of what systems theorists mean by punctuation, although punctuation typically refers to the question of how far back in time the narrative goes—who started the conflict.)

A man is obsessed with whether his wife is cheating on him. He sees only the wistful smile on her face as she contemplated lunch with a business associate. He does not zoom in for details of the smile; he does not zoom out for an assessment of her character or their marriage.

An employee repeatedly reprimands people for not doing their jobs. She sees slackers and sinners, supported by a zoom level that highlights work not done. She does not zoom in to consider her feelings about the work or her associations to slacking; she does not zoom out to consider the relative unimportance of the work to the overall functioning of the business or to consider her confusing role in the organization (maybe she thinks that being there longer than others means that she is in charge of them).

All the major theoretical orientations have zoom buttons for going in or out. Psychoanalysis zooms in on affect or out to personal history; behaviorism zooms in to specific behaviors or out to occasioning environments; cognitive-behavior therapy tends to zoom only in, to thoughts and patterns of thinking; systems theory zooms in to role-relationships or out to roles in larger systems.

So when you’re unhappy, try hitting the plus or minus button on that little scale on the side of your visual field. You could change your perspective without even changing your seat.

Pantoum (My Greatest Fear)

A pantoum can be of any length and any meter. Its defining feature is that its stanzas are each four lines, and each line repeats once in the poem, in a fixed order.

My greatest fear is fear of death.
Cruel death, please spare me in my bed.
A thought that makes me short of breath:
New tales await me—yet unread.

Cruel death? Please. Spare me. In my bed,
I’m sure of sleep and pleasures new.
New tales await me yet—unread.
Oh, may I love and be loved, too.

I’m sure of sleep and pleasures new.
I’m not afraid of going flat.
Oh, may I love and be loved, too.
How blessed am I if I may that!

I’m not afraid of going flat.
A thought that makes me short of breath:
How blessed am I, if I may, that
My greatest fear is fear of death.

The Myth of Independence

“He depends too much on the opinions of others for his self-esteem.” How many times have you heard this or its equivalent? A significant number of psychotherapies take something like this as their goal; they try to promote self-esteem independent of the esteem accorded to the patient by other people. “She turns to others instead of feeling self-confident.” Same deal: the therapist wants to help her feel good about herself regardless of what other people think. (Of course, these same therapists are all-too-often quick to praise their patients, apparently unaware that they are selling dependence on the therapist as a kind of methadone treatment for the addiction to other people.)

George Eliot, in Daniel Deronda, had this to say on the subject: “independence, as we rather arbitrarily call one of the more arduous and dignified forms of our dependence.” She meant that the relational posture we call independence is not, after all, independent of other people but is instead one that requires the “independent” person to avoid appearing needy, and since we are an extremely socially needy animal, maintaining that appearance can wear you down. Independence means you can’t ask your friends if you talked too much at dinner; you can’t express feelings of being hurt when you are left out of plans; you can’t make your partner feel important. In other words, independence means you won’t get corrective feedback; you will be left out of plans; and your partner will either be someone who doesn’t feel a right to be important or who starts to look elsewhere for that feeling. That’s the arduous part. It’s “dignified,” because, as Skinner teaches us, “dignity” just means that the things that drive you are kept hidden from other people.

Instead of trying to feel good about yourself, you should spend more time with people who feel good about you. This is not easy to do, because those people are not easy to find. One reason they are not easy to find is that many people were raised by people who don’t particularly like human beings (especially the basic human qualities of sexuality, aggression, humor, and insight), so many of the people you come into contact with won’t like you if they get a glimpse of your sexuality, aggression, humor, or insight. You imagine the best you can do is to surround yourself with people who tolerate you, and you feel bad about yourself. These people feel good about you, but they don’t really know you.

Two people I can pretty much guarantee will get you and like you are George Eliot and Leo Tolstoy. Spend time with them and their kind; find yourself in their work; experience their fondness and humor.

You can also cultivate people who will like you by liking them first, not their affability and politeness but their basic human qualities. This will change the norms of whatever group you’re in and make it more likely that your own sexuality, aggression, humor, and insight will be appreciated.

People who don’t like your basic human qualities will snap at you or otherwise disapprove of you for gravitating toward people who like you, or for expressing affection for other people’s human qualities. But you can manage such punishers in the same way you manage people who simply don’t like you: ignore them and concentrate on better people.

Another problem is that you might confuse self-praise with feeling good about yourself, and you might confuse other people’s praise with being appreciated. This will make you pursue people who praise you rather than people who appreciate your sexuality, aggression, humor, and insight. Praise often communicates that you are such a loser that you need the praise to make you feel good. Its function is often to cultivate obedience to group norms rather than to offer social approval for the basic human qualities that groups often marginalize. Praise is like alcohol; it can take the edge off, but it’s not going to make you a better person like acceptance and appreciation can. We’ve all met people who praise themselves; they’re not much fun compared to people who appreciate themselves. If you want to foster the latter and not the former, appreciate rather than praise other people.

True self-esteem is, as Skinner said, the feeling you get when you have skills. An important set of skills involves negotiating social terrain, but if you do it at the expense of your sexuality, aggression, humor, and insight, you’re not really solving the problem. So go ahead. Let other people know you need them, and spend more time with the ones who don’t exploit that knowledge or act superior about it.

Finding Sugar Man

The astonishingly true story in the documentary, Searching for Sugar Man, has a lesson for each of us. The film is about Rodriguez, a pleasant Detroit home remodeler and sometime musician who cut a couple of albums decades ago. The albums never sold, but that was okay, because he wasn’t all about success anyway. Without his knowing, bootlegged versions of his music made him a huge star in South Africa, where it was rumored he was dead. In South Africa, he was bigger than the Stones. Only recently did South African music buffs track him down to Detroit, where he still lives and works, and tell him that on the other side of the world, he is a celebrated star of the first order. Since then, he has gone on tour and become wildly successful wherever he goes. It couldn’t happen to a nicer guy.

Each of us deserves some unexpected, special country where we are celebrated, where they wait at the airport for our plane to land, where they line the streets to hail our motorcade, where they scream with passionate appreciation for what we do. And every country deserves its own special musician, appreciated there more than anywhere else.

You can become someone else’s special country only if you are capable of adoration and gratitude. Maslow memorably acknowledged that you see your lover differently from the way other people do, but his delicious spin was that we see our lovers as they really are. You can become someone else’s Rodriguez only if you are capable of revealing yourself (the analogy to recording his albums in the first place); otherwise, other people’s appreciation is unlikely to be activated and, if it is, it will never soak through your social masks to soothe you where it hurts.

Psychotherapy can be one path to celebration. The patient discovers he can adore without being exploited and that he can reveal himself and still be embraced. In my view of psychotherapy, it’s just as important for the patient to get an opportunity to love safely as it is for the patient to feel safely loved. Another path is to grow up in a family that gets you and cherishes you. Another is to fall in love with someone who falls in love with you. But if you want to be Rodriguez without also being someone’s special country, their adoration of you will be hollow, and you will eventually look at them with contempt. And if you want to be someone’s special country without taking the risks of also being their Rodriguez, your love will turn to resentment and drain you dry.

Janna Goodwin is my South Africa (though without that country’s inequity, racism, and crime). She is also my Rodriguez.

The Myth of Intrinsic Motivation

You often hear that a student who reads the assignment to get a good grade is extrinsically motived, and one who doesn’t care much about the grade is intrinsically motivated. Similar language describes the behavior of athletes, professionals, and just about everyone making an effort. Generally, it is considered better to be intrinsically motivated, lest one be accused of shallowness or lacking in persistence.

There is no such thing as intrinsic motivation.

When we can identify a reinforcing consequence or schedule that maintains a behavior, we use the extrinsic label. When we can’t identify the reinforcing consequence or schedule, we use the intrinsic label. It’s that simple.

Nothing anyone does in relation to a soda machine will be labeled intrinsic motivation. The person can joyfully feed quarters into the slot, poetically describe the sound of the coins dropping into the mechanism, and dance circles of ecstasy after each quarter is deposited; we know she wants a soda. But the same person reading a book for school, delightedly turning pages, sharing well-written passages with her roommate, and cherishing the book itself appears to be intrinsically motivated when we have good evidence that she doesn’t care too much about the grade. Rather than look for other reinforcers, we invent an internal explanation (she loves learning).

Schedules of reinforcement are also important. If someone puts quarters in a slot machine, he will be rewarded, largely or minutely, at random and often enough to create a persistent behavior. The soda machine provides a soda nearly every time. If he walks into a casino, puts a dollar in a slot machine, and nothing comes out, he will not be too upset, even though he just lost out on a payout of $100,000. If he then walks over to the soda machine and puts in a dollar and nothing happens, he will bang the machine, maybe kick it, and pull the coin return lever several times, even though he only lost out on a soda. If a behavior is consistently reinforced, extinction is quick (and experienced as frustration). That’s why you get mad at your loving spouse more quickly than at your officemate when neither notices your new shirt or your clever remark. When behavior is reinforced intermittently, as in a casino, it takes a lot of failures before you stop trying (extinction is slow), and the process is experienced more as despair or longing than frustration.

A stranger to the situation would describe the person at an unyielding soda machine as extrinsically motivated by whatever’s in the machine and the person at an unyielding slot machine as intrinsically motivated since the person doesn’t seem to expect anything from the machine.

The main reason we can’t identify reinforcers, according to Skinner, is because it is undignified to get caught working for a reward. Erving Goffman and Keith Johnstone would say it is undignified because it is something that children can’t avoid, and adults get status-enhancement (Johnstone) or avoid stigma (Goffman) by acting in ways that children can’t. Children obviously stare at the cake all through dinner and wolf down their dessert. Adults lose face if they get caught doing either. The name for the mutual agreement to disguise our motivations at dinner is “table manners.” (I acknowledge that “table manners” also describes behavior that makes the meal more appetizing to other diners.)

The main problem with the concept of intrinsic reinforcement is that it doesn’t give the teacher much to do to build skills. Mainly, the concept makes teachers shame students who reveal what reinforces their behavior. But if teachers know which reinforcers are effective, they can use the knowledge by arranging for the reinforcement to depend on approximations of the skills that will serve the student later. Or the teacher can create conditioned reinforcers by associating, say, passing the ball with, say, winning to create a reinforcer the teacher can control.
