The Diseases of Modern Life as seen through the Secular Confessional

Thus, the fact that infidelity has been assessed using different methods across different studies may help to explain the inconsistent findings across existing studies. For example, if the current data obtained from the two modes of interview had been reported in two separate studies, three predictors would have been significant in one study but not the other, and the magnitude of the effects for four of the predictors would have been significantly different between the two studies. As such, the present findings regarding significant differences in the magnitude of the association between predictors and infidelity underscore the importance of consistent use of assessment methods across studies if a replicable set of predictors of infidelity is to be identified
Neither the respondents' nor the partners' education alone had an independent effect on sexual monogamy for married women. Statistical significance for respondents' and partners' education among married women was reached only when the educational homogamy measure was added tothe model. Educational heterogamy, however, had a very dramatic effect on sexual monogamy among married women. When married women were more educated than their husbands, they were significantly more likely to have secondary sex partners than women married to similarly educated men. However, if the husband had more education than the wife, the effect was reversed the woman was significantly less likely to have a secondary sex partner than if her education level was similar to her husband's.
After controlling for relationship type, race and ethnicity effects on commitment emerged. Minority race or ethnicity increased the likelihood of having secondary sex partners among dating women and particularly among married women, but race and ethnicity had no effect for cohabiting women. Having previous sex partners also increased the likelihood that dating and married women would have secondary sex partners. In particular, married women with 4 or more previous partners were 20 times more likely to have secondary sex partners than married women with no previous sex partners. The number of previous sex partners had no effect on sexual monogamy among cohabiting women.
(Negative odds mean less likely to have secondary partners)1) The -483 Odds ratio seems difficult to comprehend when it was based on the findings of 24 women. It probably represents the fact that there were no college-degree educated women amongst the married with secondary sexual partners and statistical "magic" conjured the number.
The results presented in this article replicate findings from previous research: Women who cohabit prior to marriage or who have premarital sex have an increased likelihood of marital disruption. Considering the joint effects of premarital cohabitation and premarital sex, as well as histories of premarital relationships, extends previous research. The most salient finding from this analysis is that women whose intimate premarital relationships are limited to their husbands—either premarital sex alone or premarital cohabitation—do not experience an increased risk of divorce. It is only women who have more than one intimate premarital relationship who have an elevated risk of marital disruption. This effect is strongest for women who have multiple premarital coresidental unions. These findings are consistent with the notion that premarital sex and cohabitation have become part of the normal courtship pattern in the United States. They do not indicate selectivity on characteristics linked to the risk of divorce and do not provide couples with experiences that lessen the stability of marriage.Executive summary: It's not the liberal values, it's the number of partners that matter.
This limitation notwithstanding, the results presented here should shift attention away from research that focuses on the selection of individuals into cohabitation and premarital sex to a focus on the selection of individuals who do not marry the individuals with whom they first cohabit or initiate first sex. It may well be the case that, irrespective of the legal status of the relationship, the relevant distinction to make is between people who form multiple relationships and people who form a single, longer lasting relationship.The paper data and methods can be found here.

Slut, of course, is the term applied to a promiscuous women and debates rage as to what number of partners earns the title. I think this is the wrong way of looking at the problem. The real danger of a promiscuous woman is that she will be unfaithful, so the definition should be really centered around that concept. i.e How many sexual partners does a woman need to have before she becomes high risk marriage material? The study quoted above asked the question.The study, Harmful Effects of Early Sexual Activity and Multiple Sexual Partners Among Women, by the Heritage Foundation did nothing of the sort. The study did not look at how many partners a woman needed to have before she became unfaithful, rather the study looked at the number of partners a woman had and her risk of divorce, an important distinction.
I suppose what I'm trying to work toward, to speak very grandly, is an inclusive understanding of human reason -- the constellation of things by which we understand the world and make sensible decisions -- that takes our limitations seriously and so recognizes that there are basic truths we need but can't fully grasp and must therefore be approached from the standpoint of tradition. So my argument is not with reason in all its aspects but with the modernist project of hyperrationality. Since I reject that project I view tradition as authoritative -- as something that knows more than I do, especially about things like the nature of the good life -- and not as an interesting array of possibilities that I can choose from as I please or experts advise. That makes me a conservative.
I don't deny that one aspect of tradition can come in conflict with others and force us to choose or that there are important aspects of human reason that have considerable autonomy with respect to tradition and can lead us to modify or break with some aspects of it. The ultimate concern after all is with the good, beautiful and true rather than tradition itself. There's no formula for recognizing and dealing with such cases though and they shouldn't be taken as the models on which we form our idea of how we normally should act.

Executive summary:
The traditionalist man viewed the world differently than the modern man and was able to produce stable functioning societies. Stable societies are in themselves a good and complex things in themsevles reflecting a positive intermeshing between man and the environment. Because the principles that they are run on are proven to work, they have more authority than innovations.
Tradition "works" and therefore is good, innovation is liable to be bad. Tradition therefore takes precedence. Old is most probably right, new is most probably wrong. Conservatism is then in essence a pragmatic bias for the old, tried and tested.
OK, now an intellectual experiment. Suppose liberalism is able to produce a functional society. For example, there appears to be no let up of the North Korean regime and its quite possible that that with time, Communism could become the "traditional" culture of North Korea. Would Kalb's successors in the future be arguing that North Korean society should not be changed by virtue of the argument of tradition?
Indeed conflating the old with the good is profoundly anti-Christian. The Bible is full of stories of men who attempted to change society (prophets) even in the presence of long established custom. Jesus himself came to tear down the temple and rebuild it in three days: Hardly the attitude of a man who reverenced the old.
Indeed the Christian tradition has a quite simple method of societal change. When society is wrong, it is meant to change. That of course assumes a right and wrong and Christianity has handled that as well. It is true that the truth's of Christianity have sometimes been obscure, slavery for instance was seen as acceptable for quite a long time. But the emphasis on rationality bought on by the Enlightenment, the recognition of human rights, etc lead to a cultural re-examination of the question and the traditional understanding of society was found to be wrong. Slavery was banned.
Kalb's fundamental intellectual error is in conflating the old with the good. Just because the old was better does not mean that the old is good. It would appear that Kalb spends a lot of time explaining why the old is good. I will concede to Kalb however, that the older society seemed better at producing human happiness than the modern, still there were many people in traditional society that lived miserable and diseased lives simply by virtue of the way that the society was traditionally ordered.
Modernism, like Socialism, did not arise ex niliho, it was a faulty solution to the real problems of the times. Indeed, Tradition can be rightly considered the midwife of these intellectual beasts. The traditional fixation of pre-enlightenment society gave no means for the dissipation of rapidly building societal pressures. Indeed Kalb's "gradual change" became a like a sticky pressure cooker valve, unable to dissipate the forces building within it, the pressure building up faster than it could be relived until the structure was destroyed.
As any evolutionary biologist will tell you, a creature in order to survive needs to adapt to change, if that change is rapid, a creature has to change quickly to survive. Unable to do so, it is dead.
The printing press, Protestantism, increasing wealth, the beginnings of scientific knowledge and population expansion made a relatively rapid appearance(from a cultural perspective) and unleashed forces which required societal reorganization. The Traditionalist response: That's not the way we do things, we'll get back to you. Society moved on.
Kalb however is fundamentally right in that the difference between Moderns and Conservatives is in their epistemology. Kalb likes to call the moderns hyper-rational, where as I prefer to call them "empirically limited". The conservatives felt that valid knowledge could be garnered from faith and intuition;stuff that couldn't be empirically verified. The Moderns rejected this and thus the discontinuity with the old. The Moderns adopted a different epistemology and in many instances a different metaphysic.
In my opinion Kalb is not a Conservative he is a Traditionalist. Though I think he is a better man than his reasoning( a lot of his reasoning is good). The Conservative values the Good and True above all else, the Traditionalist the old. I've endeavored not to deliberately misstate his arguments. If I have I have my apologies and am quite willing to modify my views. Thursday is right, Kalb is the modern Burke, warts and all.
Now the whole parable and purpose of these last pages, and indeed of all these pages, is this: to assert that we must instantly begin all over again, and begin at the other end. I begin with a little girl's hair. That I know is a good thing at any rate. Whatever else is evil, the pride of a good mother in the beauty of her daughter is good. It is one of those adamantine tendernesses which are the touchstones of every age and race. If other things are against it, other things must go down. If landlords and laws and sciences are against it, landlords and laws and sciences must go down. With the red hair of one she-urchin in the gutter I will set fire to all modern civilization. Because a girl should have long hair, she should have clean hair; because she should have clean hair, she should not have an unclean home: because she should not have an unclean home, she should have a free and leisured mother; because she should have a free mother, she should not have an usurious landlord; because there should not be an usurious landlord, there should be a redistribution of property; because there should be a redistribution of property, there shall be a revolution. That little urchin with the gold-red hair, whom I have just watched toddling past my house, she shall not be lopped and lamed and altered; her hair shall not be cut short like a convict's; no, all the kingdoms of the earth shall be hacked about and mutilated to suit her. She is the human and sacred image; all around her the social fabric shall sway and split and fall; the pillars of society shall be shaken, and the roofs of ages come rushing down, and not one hair of her head shall be harmed.
Suppose that a great commotion arises in the street about something, let us say a lamp-post, which many influential persons desire to pull down. A grey-clad monk, who is the spirit of the Middle Ages, is approached upon the matter, and begins to say, in the arid manner of the Schoolmen, “Let us first of all consider, my brethren, the value of Light. If Light be in itself good–” At this point he is somewhat excusably knocked down. All the people make a rush for the lamp-post, the lamp-post is down in ten minutes, and they go about congratulating each other on their unmediaeval practicality. But as things go on they do not work out so easily. Some people have pulled the lamp-post down because they wanted the electric light; some because they wanted old iron; some because they wanted darkness, because their deeds were evil. Some thought it not enough of a lamp-post, some too much; some acted because they wanted to smash municipal machinery; some because they wanted to smash something. And there is war in the night, no man knowing whom he strikes. So, gradually and inevitably, to-day, to-morrow, or the next day, there comes back the conviction that the monk was right after all, and that all depends on what is the philosophy of Light. Only what we might have discussed under the gas-lamp, we now must discuss in the dark.
Chesterton realised we needed to understand the "truth" of the matter before we proceeded with societal change. While Chesterton respected tradition (the democracy of the dead) he respected truth more. The aim of man and society was to live "rightly" and with that implied the concept of right and wrong.
Therefore Conservatism is therefore the desire to live rightly, from which politics proceeds.Nothing more strangely indicates an enormous and silent evil of modern society than the extraordinary use which is made nowadays of the word "orthodox." In former days the heretic was proud of not being a heretic. It was the kingdoms of the world and the police and the judges who were heretics. He was orthodox. He had no pride in having rebelled against them; they had rebelled against him. The armies with their cruel security, the kings with their cold faces, the decorous processes of State, the reasonable processes of law--all these like sheep had gone astray. The man was proud of being orthodox, was proud of being right. If he stood alone in a howling wilderness he was more than a man; he was a church. He was the centre of the universe; it was round him that the stars swung. All the tortures torn out of forgotten hells could not make him admit that he was heretical. But a few modern phrases have made him boast of it. He says, with a conscious laugh, "I suppose I am very heretical," and looks round for applause. The word "heresy" not only means no longer being wrong; it practically means being clear-headed and courageous. The word "orthodoxy" not only no longer means being right; it practically means being wrong. All this can mean one thing, and one thing only. It means that people care less for whether they are philosophically right. For obviously a man ought to confess himself crazy before he confesses himself heretical. The Bohemian, with a red tie, ought to pique himself on his orthodoxy. The dynamiter, laying a bomb, ought to feel that, whatever else he is, at least he is orthodox.
The American Constitution does resemble the Spanish Inquisition in this: that it is founded on a creed. America is the only nation in the world that is founded on creed. That creed is set forth with dogmatic and even theological lucidity in the Declaration of Independence; perhaps the only piece of practical politics that is also theoretical politics and also great literature. It enunciates that all men are equal in their claim to justice, that governments exist to give them that justice, and that their authority is for that reason just. It certainly does condemn anarchism. and it does also by inference condemn atheism, since it clearly names the Creator as the ultimate authority from whom these equal rights are derived. Nobody expects a modern political system to proceed logically in the application of such dogmas, and in the matter of God and Government it is naturally God whose claim is taken more lightly. The point is that there is a creed, if not about divine, at least about human things.It satisfies the test of Conservatism. It changed the world, but it changed it rightly.
