Oxford anthropologist J.D. Unwin studied 86 societies and civilizations to see why some collapse and others don't.

What did he find?

That sexual debauchery leads to the collapse of a civilization within 3 generations. (thread) 🧵 Image
Unwin defined four categories of cultures. Each is differentiated in its pursuit of art, engineering, literature, agriculture, etc.

1. Dead - these cultures are only focused on the day-to-day needs of life. They don't care about higher questions and so do not progress.

2. Superstitious - these cultures develop beliefs that help them explain the natural world. This can be represented in the special treatment of the dead.

3. Deistic - characterized by belief in gods or a god. This requires more imagination and higher-order thinking

4. Rationalistic - characterized by rational thinking. This was the category with the most human flourishing.

Next, Unwin defined sexual ethics and restraint into two categories.Image
Unwin's two categories of sexual ethics and restraint:

- Prenuptial - this was measured on a scale from complete sexual freedom to "remain a virgin until married."

- Postnuptial - how easy is it to get a divorce? How many wives can a man have? How faithful are the women expected to be?

What did he find?
The single most influential factor in a civilization's longevity and success is prenuptial chastity.

If people were expected to remain virgins until marriage, the culture was more likely to have all of the markers of human flourishing.

They were more likely to be an "advanced" civilization.
What was the best combination, resulting in a culture that exceeds other cultures?

You probably won't be surprised.

Prenuptial chastity combined with absolute monogamy. Absolute monogamy means one spouse for life. Image
Why was prenuptial chastity the most important?

In cultures where virginity was no longer expected, within three generations, the following disappeared:

- absolute monogamy
- deism
- rational thinking
Without prenuptial chastity, people usually regress into the lowest "dead" category as they become interested only in their own wants and needs.

They become slaves to their appetites.

Cultures that have embraced total sexual freedom collapse within three generations.

They might limp along for a time, powered by some momentum, but eventually, they are conquered or taken over by another culture.Image
In the West, the sexual revolution started in the late 1960's. Three generations (~40 years each) from then would put us in the 2070s.

Are we on the way to collapse?

The evidence points to "yes."
You cannot have both sexual freedom and progress.

Unwin: "Any human society is free to choose either to display great energy or to enjoy sexual freedom; the evidence is that it cannot do both for more than one generation."
Sexual freedom unleashes all sorts of demons on a society.

Couple it with modern medicine, which basically baptizes sexual debauchery with antibiotics and abortion, and you have an acceleration of collapse.

Slaves are too busy having orgies to be truly productive. Image
It turns out that marriage is not just a private contract between two individuals.

It has ramifications for the entire community and culture.

How a society views and treats marriage determines whether or not it will keep things like indoor plumbing and modern dentistry.

What two (or more) people do together in the bedroom is not, indeed, a private matter.

Writ large, it has consequences for that entire civilization.
Likewise, porn is cultural cancer.

It rots the bones.

A healthy civilization, or one that wants to progress, will want to eradicate it or push it to the fringes of society. Porn leads to other debaucheries. Image
Looking at the current state of our culture, is there any hope to avoid collapse? It looks bleak.

Even recently, close to a pandemic, we've even people engaging in orgies and other risky sexual behavior, despite a new disease called monkeypox.

They really are slaves to their passions.
The good news: a culture can be turned around. Massive repentance can bear fruit.

But based on the data, it also takes three generations for improvements to start showing up.

Sexual ethics is a powerful rudder, but it is still a rudder on a huge, lumbering ship. Better start turning the wheel.

I've been informed the first picture is actually Aldous Huxley. Whoops.

I was looking for a higher-res photo and trusted Google too quickly.

In 1895, a French social psychologist named Gustave Le Bon published a book so dangerous that it became the private playbook of dictators for the next century.

Hitler quoted it. Mussolini kept it by his bedside. Edward Bernays used it to build modern propaganda.

The book's name? "The Crowd."

Its core claim: The moment people form a group, they become stupid. Not slightly dumber. Fundamentally, structurally incapable of rational thought.

And the tactics he described for controlling them still work on you right now. 🧵 (thread)Image
Le Bon's first defined what a "crowd" actually is.

A crowd is not just people standing near each other. A thousand strangers in a train station are not a crowd. A crowd forms when individual consciousness dissolves and a collective mind takes over.

Six people can be a crowd. An entire nation, separated by thousands of miles, can be a crowd. The question is not proximity. The question is whether individual judgment has been surrendered.
3 forces transform individuals into a crowd:

✅ Anonymity - The feeling of invisible power that comes from being part of a mass. Responsibility vanishes. Restraint vanishes with it.

✅ Contagion - Every emotion becomes infectious. Sentiments pass through a group the way a virus passes through a body. One person's panic becomes everyone's panic.

✅ Suggestibility - The individual enters a hypnotic state. Le Bon compared it directly to hypnosis. The conscious personality disappears. What remains obeys.

Once all three kick in, something startling happens.

In 1377, a North African scholar studied every empire and dynasty to answer one question: why do civilizations always collapse?

What did he find? That soft, effeminate men destroy every empire within 3 generations.

No exceptions.

His work reads like a description of the modern West, and almost no one has heard of him. (thread)🧵
Ibn Khaldun, in his book The Muqaddimah, looked at the Arab empires, the Persians, the Romans, the Berber dynasties, and dozens of others.

He asked one question: Why do civilizations rise, and why do they always fall?

There is one force that builds every civilization and one force that destroys it.
The building force he called 'aṣabîyah. "Group feeling."

The bond of shared blood, shared struggle, and shared purpose that holds a people together.

The destroying force: luxury.

Every empire follows the same arc between these two poles.

"Group feeling" and luxury, the latter causing decay in the former.

How to make your wife despise you.

1. Always ask for permission.

Treat your wife like your mom.

Never do anything on your own initiative and never make any plans without asking if you’re allowed to do it. Don’t just join the gym. Never plan a night out with friends.

Pretend that you’re just being considerate when really you want to foist all the responsibility onto her.
2. Overshare

Gossip like a woman to your wife, as if you’re just one of the girls.

Vomit out your feelings at every opportunity. Burden her with every little anxiety and fear. Make a habit of crying often. Treat her as an emotional crutch.

Act like an absolute mess at the merest hint of failure, conflict, or difficulty.
3. Never make any decisions

The magic words are, "I don't know. What do you want to do?"

Never be decisive. Always second-guess your own decision. Be silent until your wife steps in to save the day. Making a decision means you might make the wrong decision and look foolish, so better not to make any decision at all.

How doing the laundry and cleaning the house helps conquer the world.

It makes sense once you think about it. Civilization thrives when noble women stay home to manage their households.

If women refuse to work at home, civilization regresses.

🧵👇 "Who is this who looks down like the dawn, beautiful as the moon, bright as the sun, awesome as an army with banners?" a woman doing laundry with children playing in the yard.
A growing civilization depends upon men who are willing and able to take responsibility for others beyond their own households.

These men must be able to pay attention to things external to their immediate interests.
If men have to worry about their domestic affairs, they have to keep dedicating attention back home.

They'll never be able to serve their community properly as judges, councilmen, generals, etc.

They will be too busy taking care of their own homes to worry about others.

33 lessons every father must teach his son:

1. Do not gloat in victory.

Everyone already knows you have won. Gloating turns defeated opponents into lifelong enemies. Being gracious in victory creates lifelong friends.

Point out something they did well, and ask how they did it. Image
2. Do not whine in defeat.

You will gradually get fewer and fewer invites, and you will never get better at the thing you just lost at.

Every loss is a moment to learn, but if you are a sore loser, no one will want to teach you.
3. Focus on skills, not outcomes.

Skills will compound together, and eventually, the outcomes will take care of themselves. Learn to enjoy the journey. Demand excellence from yourself.

Remember, anything worth doing is worth doing badly.
