Passionate love and marriage


Myriam Tinti, an Italian acquaintance and a jurist, has communicated this interesting idea to me:

It is well recognized in the world literature of love, from Plato onwards, that there is such a thing as the “madness of love”. Neurobiological studies show that, when we look at the picture of someone with whom we are passionately in love, there is activation in certain specific parts of the brain but there is, as well, a de-activation of significant parts of the cerebral cortex. Among the areas which are de-activated are ones which have been associated with judgment.

If we accept that those who are passionately in love tend to be far less judgmental about their lovers – and there is little reason to doubt this – and if we accept further that this lapse in judgment is not general but specifically concerns the lover, then we have to accept that it is in general useless to argue with one who is passionately in love that “they have taken leave of their senses” even though they may seem otherwise quite sane and normal; it is useless to ask them to re-consider their relationship or renounce it. It is useless to try to reason with them that the union they propose is with the “wrong person” or that it runs counter to their culture, or economic or social status. Such arguments will make little difference to them.

This creates a problem. A cortical de-activation leading to a lapse of judgment may lead one to do things that they might later much regret, and if the lapse of judgment is specific to their romantic and passionate liaison, it might lead them to propose a permanent union in the form of marriage, even when (to others), such a course of action appears to be fraught with potential difficulties and possibly doomed. [In film, the transition – quite sudden – from passionate love to hate is well captured in Ingmar Bergman’s film, Summer with Monika]. What Miriam Tinti was suggesting is that one should consider the possibility of discouraging formally people who are passionately in love from getting married. Marriage is a big step and, at least in theory, a life-long commitment. It is a decision that must be reached with a good judgment, when one is in full possession of all one’s faculties. But if the judgmental system is de-activated, then a good judgment is not possible. Nor is it possible to convince people who are passionately in love that what they are embarking upon is a folly. Hence a “cooling off” period may be highly desirable.

The French use the term mariage de raison to characterize a marriage that has been agreed upon in full possession of one’s judgment; implied in this is the supposition that the decision to marry has not been reached during a lapse of judgment, and has not been reached when in a state of passionate love, which would constitute a mariage d’amour.

As I understand it from Myriam, the Catholic Church, which does not accept divorce, will nevertheless consider the lack of a discretion of judgment as a reason for annulling a marriage, if it can be proven that the marriage was entered into when one or the other had lost their judgment.

The relevant passage from the Codex Juris Canonici [Code of Canon Law] (Can. 1095, n. 2) reads as follows:

 The following are incapable of contracting marriage:
1° …
those who suffer from a grave lack of discretion of judgment concerning the essential matrimonial rights and obligations to be mutually given and accepted

Given that something like 50% of marriages in the Western world end in divorce and that many of the remaining marriages are sustained only for economic or social reasons, the issue of whether people who have lost their judgment because they are passionately in love should be formally asked to defer their marriage is worth considering. And passionate love is one of the conditions in which people appear to lose their judgment with respect to their lovers.

There are of course major problems as to practicalities, especially regarding how proof can be obtained. Tests would constitute a serious invasion of privacy (though it is interesting to note that a form of invasion of privacy was practiced in some countries, and still is in some states of the United States – the requirement for a blood test before a marriage license was issued, to ensure that neither party was suffering from a disease that could be passed on to the children – principally syphilis). Much less intrusive would be a good form of education – starting with sexual lessons at schools – that during passionate love, judgment is at serious risk of being suspended and that to enter into a marriage contract in that state carries with it serious potential problems.

At any rate, this is an interesting idea, which merits consideration.

Fighting the consequences of cortical de-activation with another cortical de-activation

Some time ago, I wrote a post in which I questioned whether greed can be regulated by courses on ethics and ethical behavior. Greed is, after all, a biological phenomenon and, I argued, that when humans are faced with the prospect of untold riches, their cortex is probably significantly de-activated.

There is no definite evidence for this, greed itself not having been studied neurobiologically to my knowledge. But there is evidence that a neural correlate of being passionately in love is the de-activation of significant parts of the cerebral cortex, which probably is one reason why we tend to be less judgmental of those we deeply love, and sometimes act in apparently irrational ways when in love.

I believe, therefore, that it is pointless to give lectures on ethics and ethical conduct to those who plan to go into the financial world; it is just as pointless to start talking about “ethical stocks”, an idea floated by some businessmen. Because of cortical de-activation, the prospect of great wealth also leads to a lapse of judgment in other areas, including moral conduct, or so I argued.

What I had not considered was that it may be possible to fight greed in one area – making unlimited sums – with greed in another area, sexual gratification. But now comes a report from Spain that this might just about work.

Sexual activity also leads to massive cortical de-activation. I suppose, but I am not sure, that the desire for sexual gratification also leads to much cerebral de-activation. Hence judgment about making money (greed) may be suspended when much of the resources of the brain are concentrated on obtaining another biological gratification, with the attendant cortical de-activation.

Apparently
, the escort girls of Madrid have gone on strike to deny bankers the sexual gratification that the bankers seek – until they behave in ways that are more morally acceptable to the escort girls. This appears to have led to some irrational behaviour on the part of the bankers.

Hilariously, the escort girls of Madrid may have – just – hit on the right formula to temper greed.

Read about it for yourself.

An insightful Daily Mail cartoon on beauty and brain activity

There was a neurobiologically interesting cartoon that accompanied the Daily Mail article on our most recent brain study on beauty, published in the open access journal PLoS One last week (you can access the paper here). The study shows that activity in a region of the brain’s pleasure and reward centre, the medial orbito-frontal cortex, correlates with the experience of beauty, whether the source of the beauty is musical or visual. A previous study by another group had shown that this same region is also active when subjects view beautiful faces.

The cartoon by Pugh has a man looking at the photograph of an ugly woman (his wife), with the caption saying “My medial orbito-frontal cortex let me down when I married her”.

There may be some truth to the cartoon. A previous study by us on romantic love had shown that when people who are passionately in love view the picture of their loved partner, significant parts of their cortex become de-activated. This may be the reason why we are commonly less judgmental about those we love.

Purely as conjecture, it may be that when the fictitious character in the cartoon was courting his future wife, with whom he may have been passionately in love, there was significant deactivation of much of his cerebral cortex, leading him not to see her ugliness.

As his love wore off, and with it the de-activation, he became more judgmental and saw the ugliness which he had not seen before.

There are of course other interpretations. But this interpretation is what comes immediately to mind when viewing this cartoon.

You see, one can get ideas about experiments from all kinds of sources.
