The Four Horsemen of the Apocalypse: Conquest, War, Famine, and Death.
The first time I remember hearing about the Four Horsemen of the Apocalypse was not in church but from a song by Aphrodite's Child, when I was in high school:
Death: Some 70 million abortions. At this rate, babies will be killed after they are born (maybe placed in jars outside, the way the Romans did), if they are born with defects that was missed while they were in utero (here we use the advice of the Spartans). The elderly will be unwillingly euthanized, perhaps knocked in the head or smothered with a pillow. (I'm waiting for cannibalism, ala' Soylent Green, although perhaps using fetal tissue in vaccines and make-up might count - unless these things are merely Urban Legends. Guess which one sorta isn't?).
Conquest: That would be the State, which itself is an ever-growing monster, sucking away all our rights and trying to enslave us and turn us into the Borg, i.e., organic machines, cogs in the monster, in the manner of Metropolis.
Is not Conquest related to War - and therefore Death? In the 20th Century, there may have been 200 million murdered in various wars. No one is quite sure. Who counts peasants?
As for the 21st Century, what the U.S. has done to the world is astonishing, under the guise of humanitarianism.(Isabel Paterson called such ideologues, "The Humanitarian With a Guillotine.")
Now all of these things are pretty obvious. There are other things a bit more subtle and requiring more thought and analysis - although all of them fall under the Four Horseman.
Let's take the Four Sirens. (Creepy how there are four of them, isn't it?)
Easy Contraception. You'd think people would be responsible about this - and many are - but many aren't. Example: in his 1953 book, Childhood's End, Arthur C. Clarke predicted the end of marriage because of easily-available birth control, because it severed the link between sex and procreation, which would cause us to turn into "a culture of sex for pleasure and recreation unrelated to marriage and child raising."
Now you think that might not be a bad thing, but it's led to excessive promiscuity and the prevention of marriage. And there is no incentive for most men to do anything except withdraw and Go Their Own Way, or else become Cad/Sexual Predators who lie to and manipulate stupid women.
G.E.M Ascombe put it this way: women don't have to bear children if they don't want to, but they can still get men. Or they can have children without marriage. She also pointed out that Christianity was "at odds with the heathen world, not only about fornication, infanticide and idolatry; but also about marriage..."
In other words, we are now in the post-Christian world of Neo-Paganism, with fornication, infanticide, easy no-fault divorce, polygamy (in various forms), adultery, and idolatry (these days, that idol is that Moloch known as the State - which really means we worship ourselves).
No Fault Divorce, Asset Division, and Alimony. This is the second Siren, and it, too, falls under Neo-Paganism.
In the past a couple had to prove one spouse was at fault. Not anymore, but unfortunately the Law (sic) allows most women to get a divorce for no reason, takes her ex-husband's kids and money, and also get money from the government (which means from taxpayers). Under this system there is no incentive for men to get married, and since marriage is the basis for society, this is one more nail in the coffin of society and civilization.
The third Siren is Female Economic Freedom. Technically there is no such thing. Men created everything. Women who did are outliers. It's not due to "patriarchy" and "oppression" but because men and women have different brains. So what we've got are women either marrying men or marrying the State.
The only reason women have their pseudo economic freedom is because men, dupes that they are, let them be parasites who obtain worthless degrees that are used for parasitical make-work jobs.
Women's entry into the workforce would be just fine if they were productive (and some are) but many of them, I repeat, are just worthless parasitical "jobs."
Additionally, if women have highly-paid jobs, they are going to look around for what they consider an acceptable husband, and they then find he's not there, since many high-paying blue-collar jobs have been outsourced, and Affirmative Action means "White Men Need Not Apply."
So, then, marriage takes a big hit...and we descent further into Neo-Paganism.
The fourth Siren is Female Social Engineering. Many women are totalitarian/fascist/socialist in nature, and I really don't have to explain the destructive aspects of that - except to say, "Look at the schools.") I should add there are reasons there has never been a matriarchy in the history of the world...and they are good reasons.)
The biggest problem is the interference of the State and its "laws" (sic). If we had the proper laws, most of these problems would be alleviated.
1). Get rid of no-fault divorce.
2). Single mothers are not allowed to keep their children.
3). In a divorce the children are given to the father, which means no alimony for women.
4). Get rid of Affirmative Action.
5). Women are not allowed to vote.
I would settle for just those four things. The changes would be all to the good, and I see no downside to any of them. If we don't do them, get ready for the sounds of approaching hooves.
