Love Under a Microscope
smooth wombat writes "As today is one of the top five marketing-induced spending days, the obvious question is, what is love? Anthropologist Helen Fisher studied the brain's circuitry and found that the brain sees romantic love as a reward similar to chocolate, money or drugs. Does this mean that the mystery of love is less magical now that science has studied it under the microscope? According to Dr Fisher: 'You can know every ingredient in a piece of chocolate cake, and you still sit down and eat that chocolate cake and it's wonderful,' she said. 'In the same way, you can know all the ingredients of romantic love and still feel that passion.'"
From TFA:Since the odds of survival for a human child with two parents is (or at least was) much higher than the odds of a single-parent child, it shouldn't be surprising that humans have a strong drive to forge lasting relationships. Natural selection in action, and all that.

This touches on the issue of mind / brain duality.
Is our mind something that's simply a meta-effect of the brain, so that for instance if you view/control my brain you can fully know / control my mind?
Also note that the answer to this has serious implications for free will, the justice of retributive punishment, etc.
Nothing better than making love with your mate/spouse than after smoking a good joint.. the sense of touch is enhanced, the the beat of the music just flows...., the orgasm is better... so ya I'll pick the drugs option. Start it out by going to an open-air concert if the weather is accomodating in your area, make sure it's a quality strain of bud and pre-roll them before you go out.

I read such a topic 3 weeks ago in National Geographic. The article was pretty well written. Chemical imbalances, irregular brain patterns and oxcotin (i think that was the chemical).
Check out this video. Pretty cool.
Since I lack the philosophical education to completely explain what "Love" is (other than a simple chemical addiction from the brain ;) ) I will not attempt to answer that here.

And the only one that applies to this research is romantic love. Not that the article doesn't explicitly say that, it certainly does. But I think it's worth bringing up though. Some people use the word love as if it's singly defined, but many cultures define love differently.

I gotta say, I've never understood this... when people eat chocolate they actually FEEL something? They get the warm and fuzzies? I sure don't... it tastes nice and all, but that's it. Maybe in a similar way to how I'm immune to caffeine (Drink 3 Jolts and go right to sleep) I don't FEEL the chemical for love? People have said I'm cold and heartless a few times, I guess chemical sensitivity affects our personalities more than we think. Perhaps some don't feel love or other positive affections and simply have no desire to be a nice person. A new way to stay out jail perhaps? Instead of "He had a bad childhood" we'll hear "He simply doesn't have the chemical receptors for love."

The Greeks had four words for love: agape, phileo, eros, and storge. We English speakers seem to conflate everything around eros and thereby miss the point. Love is the act of the will whereby another individual is placed ahead of yourself. That's why Christians are commanded to "love their enemies" and why the Apostle Paul wrote that the greatest act of love was when God gave His Son as the sacrifice for the sins of the world.
No naturalistic scientist could ever write:
Love is patient; love is kind; love is not envious or boastful or arrogant
or rude. It does not insist on its own way; it is not irritable or resentful;
it does not rejoice in wrongdoing, but rejoices in the truth.
It bears all things, believes all things, hopes all things, endures all things.
Love never ends.

1. the traditional romantic-type love, a crush. a person can't stop thinking about another person, many times a minute even, to the point of mental distress. this is very definitely like addiction
2. long-term love. this is when you operate on a day-to-day basis with the other person as if you were a unit, and you can finish each other's sentences and such. you don't think of the other person constantly, you just coexist with them fluidly (albeit with a certain level of conflict). if the person were to leave or die, you would experience great stress, as if you had lost a limb
i think evolution set this up pretty well. romantic love is the almost gravitational chemically-driven attachment you have with someone else that allows for the binding of two organisms together socially. then, as the chemicals subside, you are left with permanent neurogical patterns and structures in both organisms such that you function as a social unit
good design, i think, albeit with unavoidable failures such as:
1. chemically bonding with someone who does not like you (stalking, obsession), your classic unrequited love
2. ongoing long-term conflict that does not resolve, where you are bound to someone you have serious differences of opinion with. classic marriage counseling fodder and irreconiable differences divorce papers issues

There are people who'd say things like that about their preferred batch of ingredients. We call them junkies, the chemical they use is called by many names -- not the least of which is junk. When a junkie is deprived of junk, they go through withdrawal. They experience physical pain, depression, and often behave irrationally or self-destructively in order to get their fix.
I (like most of you) have used oxytocin. Like heroin users, when deprived of their fix (or even when threatened with their supply of the drug being cut off), oxytocin users feel depressed, lethargic, some feel physical pain - right in the chest/gut area, and are also prone to self-destructive and irrational acts.
From TFA:
You can know every ingredient in heroin, and you can still sit down and - oh, wait. Once you know what heroin does to human neurochemistry, you can choose not to take the shit, and if you're a junkie, you still have the choice to stop.
Just because my former drug of choice happened to be secreted by my own endocrine system didn't make me any less a junkie.
Mercifully, the 2-3 year pair-bonding mechanism built into your brainstem puts a limit on the withdrawal: if you stay clean, that's about as long as you're physiologically capable of feeling oxytocin withdrawal symptoms. Once you're through that phase, the cravings disappear, and they stay disappeared unless you do something stupid.
So if I make chocolate I'm making love? Could it be perhaps the thought that "I love chocolate" tricks these scientists into believing that love is the same as chocolate? What if they asked the subjects to write down what their favorite food is and then see the patient's reaction when they talk about it. I bet it'd be considered love too. I love fish's cause they're so delicious! Love can be fear too... "I think I love you, so what am I so afraid of?"I think the Partridge Family sings that
Love is an illusion created by a mix of chemicals in the brain. It has nothing to do with any deep spiritual connection. It's merely your animal side reacting to the stimuli of oxytocin (not to be confused with Rush Limbaugh's drug of choice: oxycontin). If you expunge the animal side of your nature, you can see the world clearly and without being influenced by such ridiculous concepts as love and passion. Stop lying to yourself. There is no such thing as love. Or is there? Check my sig link to find out for sure...

If the "mystery of love" has been studied to the same extent as chocolate, than I would suggest that our understanding of how it works and the effects it has on us are a long way from being understood.
Put another way, if you take the 400 or so compounds in chocolate and study them invidually (putting aside the need to study all the possible combinations), you'll end up with something like "Big boobs in the female of the species increases the chances of successful mating." Hardly useful. Or informative.
My guess is that we'll be studying chocolate (and love) for years to come. And given that our science isn't much more evolved from the Poke It With A Stick And See What Happens method, we might as well enjoy the mystery. And the big boobs.
But Love. Deep seeded, infallable, uncorruptable, everlasting love .
Infatuation, maybe.
I'm only using the following example for lack of an equally recognizable one, and religion aside, but the same type of love Jesus would have felt had he existed? To love someone(s) enough to completely fuck yourself over for them in order to prove a point? To love someone enough to never forget them (and the tender emotions held with their memory), throughout your entire life, without regard to what had caused the fallout (be it cheating, offense, abuse, etc)?
Love isn't simply a chemical reaction. It's a philosophical conundrum and, perhaps even, an imaginative creation. For all we know, we could have simply invented the concept of "Love" and are now desperately trying to explain something who's meaning has been lost and contorted with time. If you ever stop loving something (even for a moment), then you never loved it to begin with. Even hate is nothing more than resentful love; you can't hate something without having loved it first.
That's why the only person who's ever heard me say "I Love You" has been my mother. Not even girlfriends get that special treatment. They'll get a "I'm infatuated with you", but nothing more (of course that is, until I find someone I find deserves it).

Um, what? Just because AI isn't currently up to the level of reproducing the brain doesn't invalidate a reductionist view of the mind. Read Godel, Escher, Bach for a discussion of how even a reductionist mind requires a very complicated (and not yet produced) AI.
I've read GEB, but thanks for the appeal to authority. I didn't say anything "invalidated" the reductionist view; I just said that it was casually assumed without justification, and no advances predicated thereon have been made, rendering such an assumption tenuous. And I'm still waiting for someone to come up with the Goedel statement that's supposed to crash my brain like the Turing machine it supposedly is.

To paraphrase Eddie Izzard ...
"Cake or Love?"
"Cake please!"
Heh. Those who have been successfully married for more than a year know this to be true. It's damn difficult to love a person sometimes, because sometimes even the best mate is almost unlovable. If love was no more than a kind of "wanna get some" reflex, most marriages would be annulled after the first week.
Well, if not reductionism, then what? The more we learn about the brain, the more we find surprisingly small systems controling surprisingly specific elements of the mind. And as for no advances predicated thereon, what do you call Prozac and other medications? Find the specific brain system which leads to a given disorder of the mind, develop a pharmacological or surgical technique to correct it, profit. It's not all about computer science.

Nice try, though.
You might feel like you're correct but there is no absolute right or wrong when a person alters their brain chemistry. If you're judging me from a moral basis, then I have no argument. You will always be right and I will always be wrong. But why are you wanting to pick a fight with people that have no problem altering their own conciousness? It's theirs, not yours. Do you make the same arguments with your friends (if you have any) that consciously and willfully alter their brain chemistry/nervous system when it's caffiene? or chocolate? Or maybe they have passion for bubble baths. You're arguing against a completely natural and healthy need for human beings to transcend the daily reality they live out. What you're doing is completely unhealthy and probably causes more brain damage to yourself than cannabis will ever do.
Now I'm sure you live a very healthy and productive life. You probably don't smoke, don't drink coffee, will never sky dive or eat chocolate and live a perfectly celibate life. I respect that, I never attacked what you make of your life did I?
For the rest of humanity, for the people that have not graduated with honours from their local high school DARE program like you have, we will continue to enjoy what life has to offer us. I have no problem with your personal choice, but please don't be so quick to judge people based on what you personally believe is a moral failing. Your morals are not mine.

You mention four aspects of love and then focuses on only on a Bible-oriented version of agape. Why not devote equal time to phileo, eros and storge?
I would recommend praticing what you preach, "wrf3". Your attack on scientists certainly is un-agape-like, as well as doing a disservice to the Slashdot community.
- A biologist wrote "The Life of a Cell", a paen to the wonder of biology and creation.
- Einstein loved Mozart and was an accomplished violinist, who played with passion.
- It would be very hard to characterize the famous psychiatrist Carl Jung as an unpoetic character.
Looking around this world one can, after prying their nose out of the Book of Corinthians, definitely find scientific poets, and poetic scientists. And a love of mankind certainly does not preclude a passion and love for nature and the universe.
Perhaps another poem about love is appropriate. Hopefully the this poem titled "Dust" by Rupert Brooke, will be suitable this Valentine's day.
When the white flame in us is gone,
And we that lost the world's delight
Stiffen in darkness, left alone
To crumble in our separate night;
When your swift hair is quiet in death,
And through the lips corruption thrust
Has still'd the labour of my breath -
When we are dust, when we are dust !
Not dead, not undesirous yet,
Still sentient, still unsatisfied,
We'll ride the air, and shine, and flit,
Around the places where we died,
And dance as dust before the sun,
And light of foot and unconfined,
Hurry from road to road, and run
About the errands of the wind.
And every mote, on earth or air,
Will speed and gleam, down later days,
And like a secret pilgrim fare
By eager and invisible ways,
Nor ever rest, nor ever lie,
Till, beyond thinking, out of view,
One mote of all the dust that's I
Shall meet one atom that was you.
Then in some garden hush'd from wind,
Warm in a sunset's afterglow,
The lovers in the flowers will find
A sweet and strange unquiet grow
Upon the peace; and, past desiring,
So high a beauty in the air,
And such a light, and such a quiring,
And such a radiant ecstasy there,
They'll know not if it's fire, or dew,
Or out of earth, or in the height,
Singing, or flame, or scent, or hue,
Or two that pass, in light, to light,
Out of the garden, higher, higher. . . .
But in that instant they shall learn
The shattering ecstasy of our fire,
And the weak passionless hearts will burn
And faint in that amazing glow,
Until the darkness close above;
And they will know - poor fools, they'll know!
One moment, what it is to love.
Sorry about your loss... The important thing is that yall were happy!

Call me highly skeptical. Helen Fisher is a physical anthropologist. As in population geneticists, primatologists, and paleoanthropologists. This is a far cry from being an expert in studying the "circuitry" that underlies love. In her book, she hooked up with some doctors from SUNY to use MRI brain scanning to "look at what love looks like", but the book is really mostly just anthropology. In truth, we have no idea what the circuitry of love is (yet), but we have long understood the effect of endorphins (caused by chocolate, heroin, running fast, and love) on the human brain and their relationship to one another. Thus her claim is both simultaneously old hat and inexpert.

Fisher went on a quest to unravel the mystery of the brain in love. She teamed up with Art Aron, a psychologist and professor at Stony Brook University in New York and Lucy Brown, a professor in neurology and neuroscience at the Albert Einstein College of Medicine in New York.
And here's your answer! Looks like Dr. Fisher may not be a neuroscientist, but her research team indeed does include Dr. Brown, a professor in both Neurology and Neuroscience.

Please note that my "attack" was against naturalism and it was simply an observation that naturalism, with it's focus on species survival, cannot logically produce a like-minded statement about love.

What the other guy said. Also, if such "disorders" (and the whole idea of classifying any behavior we don't like as a "disease" has it's own boatload of problems) are solely defined by their physical components, why do all psychiatrists demand that the medication only be given with a counseling component? (It can't just be for the money, can it?) And why do people still systematically exaggerate the threat of those who have mentall illnesses yet are on medication?

I love humanity, it is people I hate
...very much like deciding that tears explain sadness.
I know subjectively, that even my simple emotions are complex, multilayered things. There's the sensation-level feedback which lets me know I'm experiencing an emotion. There's learned-behaviour changes like reinforcement (of love, happiness, etc) or disincentive (from pain, shame, etc). There's thought-ability changes, belief-prioritization changes, even memory recall changes. All in parallel. And that's leaving aside the experience, belief and attention context that triggered the emotion. So, it looks to me like what these guys are doing is picking at one strand (new love's pleasure/reinforcement/habituation mechanism) and thinking they have the totality. Which is just ignorant, and I'd guess it's not accidentially ignorant. More people pushing the "mind is nothing but meat" idea. Not an opinion I share!

Horns are really just a broken halo.
Indeed, I think a big portion of love is sacrifice. At the least you are sacrificing time, perhaps finance, on the trust that you will be with that person.
Some people sacrifice of their own bodies, such as those that donate an organ, etc, to an ailing relative or compatible friend, soulmate, etc.
With the former, the point at which love might be reached is when you know you would sacrifice of yourself in such a way, were it ever required of you. For those that think they are in love, consider... would you sacrifice a kidney, or other bodily organ, degrading the overall health of your body in order to assist or sustain that of the one you love?

A very interesting post, but I wonder:
I suspect that the ideal of a lifetime monogamous commitment was developed by the new State Authorities
Is there any actual evidence that a group of people got together in a back room and actually consciously invented lifelong monogamy? Because the idea seems to me just a little bit far fetched. I don't think that people are quite that insightful and forward-thinking.
At any rate, just to support what you said about serial monogamy, there is strong evidence that it was (subconsciously) an invention of women. Men, I think, would be happy roaming about like nomads, and just mating (forcibly if necessary) with any female they happen to meet. Monogamy was like a contract that women made with men. "I will stop resisting and you'll actually have more and better sex IF you agree to stick around and help with the kids." And then once the kids had aged five or six years, the contract stopped serving its purpose and both parties moved on to their next contract.
I think that lifelong monogamy just evolved out of that, as the contract term kept getting longer and longer. The more complex the civilization, the *more* support that children need. Now you've got to buy them clothes, you've got to put them through school, you've got to teach them the complex behaviors that will allow them to fit into this civilization. That takes more than just a few years.
I just think this is a better explanation for lifelong monogamy than the idea that it was invented for a purpose. I think it evolved.
Nonetheless, what you said about the state supporting marriage for its own selfish reasons, I certainly agree with. I just don't think the state invented it.
Back a few years I read a great book - Creierul, O enigma descifrata, translated from Romanian, it means "The brain - a deciphered enigma". The author named the concept "MDT: Modeling Device Theory"; the brain is treated as a device that is designed to make predictions about the real world, based on the input from the organs and the experience of the person (which is structured in models).
The book is fantastic, the author proposes an abstract model that explains how the brain works at the software level. The model is able to explain many things, including God [why we need such an entity, and what its actual role is], and love.
The idea is that the brain operates with models, which are meant to make predictions of the future, ones that are as accurate as possible. If a prediction is incorrect, the model is updated, hence the future predictions [based on that model] will be closer to the real deal. There are different models, such as school, internet, apple, etc. The models are inter-connected [think of a graph with a helluvalot of nodes]. The model "school" can be connected with the model "internet", which in its turn is connected with the model "slashdot", and so on.
Love is one of such models, what makes it different is the number of other nodes it has connections with.
Back to school and internet and slashdot: I have internet access at school, and that's where I read slashdot. If you take the school-model out, it's not a big deal; I can use another one, for instance "internet-cafe", and substitute the "dead" one with it.
That's not the case of love - take the dear person away, and the model-structure might collapse, because the absent model cannot be substituted.
This was a very generalized description. The idea is that love is just a software-level dependence: many other models point to it, and if love disappears, whatever you try to do - you get something like a null-pointer assignment.
If you understand Romanian - this book is definitely worth it!
