    As Dr Fisher explains, "you can feel deep attachment for a long-term spouse, while you feel romantic love for someone else, while you feel the sex drive in situations unrelated to either partner." This independence means it is possible to love more than one person at a time, a situation that leads to jealousy, adultery and divorce--though also to the possibilities of promiscuity and polygamy, with the likelihood of extra children, and thus a bigger stake in the genetic future, that those behaviours bring. As Dr Fisher observes, "We were not built to be happy but to reproduce."

      Actually, I was reading something the other day about how despots in ages past would have dozens, hundreds, even thousands of wives. Today, the President of the United States can't even get away with two! What could be responsible for such a dramatic shift? The explanation given was democracy (the argument against the women's rights theory was that monogamy was pretty entrenched in word and in deed by the Victorian era, when women still had no power). The lower status males will simply use their power to destroy a sexual rival. Essentially we've achieved sexual communism, where no one is allowed to rise higher than a single wife.

      All that being said, there are perfectly legitimate women's rights reasons why polygamy is wrong. No woman wants her husband to take a second wife, and even among the "mormons" (in quotes because the recognized church would say they're not mormons) in Utah who do have multiple wives only achieve that status by bullying, threatening, or simply psychologically dominating their first wives.

      Your post reflects the continuing issues of women's rights. There is nothing in the word polygamy that implies a man having multiple wives. There is nothing wrong with polygamy except for those whose moral and/or religious beliefs forbid it. Just as a man could have multiple wives, a woman could have multiple husbands.

      Now, that being said, it isn't very likely that any woman would want multiple husbands. While some emotional and economic benefits exist for polygamy in general, the downside of jealousy is always there. And on the sex issue, very few women have enough of a sex drive to want multiple husbands, whereas that problem is common for men. Evolution is so cruel.

      Now, this is not *world* war, but war in a sense.

      If you ever get to Lake Cumberland Kentucky, go to the lodge near State Dock some evening in May or June around 8pm. Thats when the guests are leaving the buffet and walk out onto the deck, food in hand, for the evenings entertainment.

      About 20 feet below, every evening, Groundhogs and Raccoons battle each other over position, and cute postures, trying to get food from patrons. This often becomes bloody, and the raccoons have taken to using weapons.

      They will run with sticks, or brushes in their mouths, and push the groundhogs off the stumps, which gives the raccoons a better chance to "impress" the crowd, and get food thrown at them.

      The groundhogs upped the ante, and *ate* the stumps down to nubs, eliminating the raccoons "performance stages".

      The Raccoons then went to plan B, and started sending their *babies* in to fend for food. The babies come out, everyone "ooh's and ahhh's" and throws food. Then the babies take the food back to the adults, who wait just at the treeline.

      Not to be outdone, the groundhogs began digging tunnels with entrances out near the patio and deck, under the bushes. When the food is tossed, they dart out (as well as a groundhog can dart) and snatch it before the baby raccoons can get it.

      It calmed down a little in the late 90's when the lodge started making an honest effort to keep people from feeding this battle of animal will.

      It still goes on however. Last time I was there, about two years ago, the raccoons had taken to climbing up the gutter drains, and walking up to customers and then just *tugging* on their clothing until they were *handed* food. (wimps).

      Since the groundhogs don't climb so well, I dunno how they will beat this tactic. Although they still get their fair share, as many people are (and probably should be) unwilling to hand feed wild animals. Therefore what is thrown to the ground still goes to the groundhogs.

      If thats not animal warfare, I don't know what is.

      By the way, the groundhogs really did gnaw those stumps down to nothing. They stopped as soon as the stumps were gone, and have not been seen gnawing on any other wood. Just the "stages" that the raccoons performed on.

    OVER the course of history it has been artists, poets and playwrights who have made the greatest progress in humanity's understanding of love. Romance has seemed as inexplicable as the beauty of a rainbow. But these days scientists are challenging that notion, and they have rather a lot to say about how and why people love each other.

    Is this useful? The scientists think so. For a start, understanding the neurochemical pathways that regulate social attachments may help to deal with defects in people's ability to form relationships. All relationships, whether they are those of parents with their children, spouses with their partners, or workers with their colleagues, rely on an ability to create and maintain social ties. Defects can be disabling, and become apparent as disorders such as autism and schizophrenia--and, indeed, as the serious depression that can result from rejection in love. Research is also shedding light on some of the more extreme forms of sexual behaviour. And, controversially, some utopian fringe groups see such work as the doorway to a future where love is guaranteed because it will be provided chemically, or even genetically engineered from conception.

Mating between prairie voles is a tremendous 24-hour effort. After this, they bond for life. They prefer to spend time with each other, groom each other for hours on end and nest together. They avoid meeting other potential mates. The male becomes an aggressive guard of the female. And when their pups are born, they become affectionate and attentive parents. However, another vole, a close relative called the montane vole, has no interest in partnership beyond one-night-stand sex. What is intriguing is that these vast differences in behaviour are the result of a mere handful of genes. The two vole species are more than 99% alike, genetically.

    Why do voles fall in love?

    The details of what is going on--the vole story, as it were--is a fascinating one. When prairie voles have sex, two hormones called oxytocin and vasopressin are released. If the release of these hormones is blocked, prairie-voles' sex becomes a fleeting affair, like that normally enjoyed by their rakish montane cousins. Conversely, if prairie voles are given an injection of the hormones, but prevented from having sex, they will still form a preference for their chosen partner. In other words, researchers can make prairie voles fall in love--or whatever the vole equivalent of this is--with an injection.

    A clue to what is happening--and how these results might bear on the human condition--was found when this magic juice was given to the montane vole: it made no difference. It turns out that the faithful prairie vole has receptors for oxytocin and vasopressin in brain regions associated with reward and reinforcement, whereas the montane vole does not. The question is, do humans (another species in the 3% of allegedly monogamous mammals) have brains similar to prairie voles?

    To answer that question you need to dig a little deeper. As Larry Young, a researcher into social attachment at Emory University, in Atlanta, Georgia, explains, the brain has a reward system designed to make voles (and people and other animals) do what they ought to. Without it, they might forget to eat, drink and have sex--with disastrous resu

      more than that, the comments in the first paragraph were a little, er, loose with the science. In schizophrenia the social implications come from the brain not getting other information correct. It's difficult to handle social interaction when your reality is different from everyone else's. Whether or not this is the case in autism is more debateable, but I think if you floated the idea that autism is caused or would be significantly helped by an increase in bonding hormones, you'd have to provide far more evidence than handwaving to be taken seriously. There's too much evidence for other causes (like scrambled sensory input during the years where social interaction schemes are first put down -- this also explains why some infants/toddlers in institutions where they do not receive significant interaction from caregivers display 'autistic like' behavior -- they do so because they don't get the interaction that an autistic child does get, but can't take advantage of because of the sensory scrambling -- I'm not saying that this set of theories is correct either, but there's a hell of a lot more evidence that that approach than a hormonal imbalance).

      But it sort of quietly echos the refrigerator mother hypothesis, which is well disproven now. It also implies that people with autism or schizophrenia have some innate issue with falling in love or bonding, caused by their illness, which isn't generally the case and is a problematic assumption made by people who don't have these conditions who then manage to project them on those that do.

There /is/ something "else" behind real love, and I cannot dare to hope to explain it to those who had never experienced it. It wasn't just lust! It was well beyond sexual, even from the start. I was more then merely smitten with her personality, I became addicted to her very being. I wished to know everything about her, and began to care more about her then myself. Its easy to think we love only to be loved, that as with biology everything is essentially selfish - but I'd sacrifce it all for her on the drop of the hat. Love must be real because I can see two distinct periods in my life, before her and after, and who I am now bears little to nothing in common with who I was before. Shes challenged me to my very core, my long held assumptions questioned- everyting is different. She is my one, and not because being apart may drive me nuts.

    They certainly aren't idiots themselves, but they are digging in a wrong direction.

    Try not to perceive it as a flamebait, but the whole point of many branches of Western applied science is to allow idiots to stay idiots and not change themselves.

    For example, eat Viagra each time before sex instead of learning Daoist or Tantric techniques and getting a rock-solid erection. Or eat Prozac instead of using psychology in order to get out of depression by eliminating its root causes.

    Another example - medicines that allow someone who have never exercised and ate crap at McDonalds to live till their retirement age.

    Thus, the entire civilization becomes one of degenerates (or, even better word, CONSUMERS. I consider this word an insult) on prescription drugs because there is only a certain small percentage of people who will do something that is not required for survival. Then longer I look at this world, then more I get disappointed in the effectiveness of a certain socialized institutions. This makes me wish the world be more succeptible towards libertarian ideas that are based on self-responsibility for your being.

    And now the right direction ;-).

    Everything said above brings us to one word that describes the place that is the key: Psyche.

    Psyche is the part of us that manages the levels of hormones, chemicals et al, and in most cases it is the level where the problems should be attacked.

    Here is the explanation why geeks don't get women. This is a "physical"/"lustful" side of love.

    (when reading it, think of Kramer versus George Costanza as the example of high/low rank, and of Klingons versus Vulcans as the example of high/low primativeness)

    There is another one - "spiritual"/"psychological" that can be understood upon reading "Games people play" by Eric Bern.

    As one can understand, all of this "chemical crap" that we eat in a form of medicine and supplements is just a way of bypassing the psyche and emulating its work. Smarter readers will understand that modern Western medicine often heroically fights with the shit that our own subconscious brought us into (think of a very typical situation with people who nobody needs, and who get sick in order to get attention of their relatives, professionals from medical institutions or good samaritans. Also read this ). And the general population pays through the socialized healthcare. And everyone is happy since everything is a good business for certain groups whithin the society. At the same time majority is swayed by the false ideals of humanism et al.
