Nixon to Moscow, slavery’s toll on the economy

My latest is up over at RealClearHistory. An excerpt:

Nixon’s anti-Communist credentials were so sound that he could spend political capital making inroads with Communist enemies. His actions were viewed as safe by the American electorate because, for better or worse, the public saw Nixon as somebody who would not betray American values at the negotiating table with the Soviets. Nixon’s hawkishness provided moral cover for America’s withdrawal from Vietnam, and its peaceful overtures to the two most powerful and aggressively anti-capitalist regimes in the world (China and the USSR).

Please, read the whole thing.

Vincent has a great review up on Robert Wright’s new book about slavery, too. It’s at, a website dedicated to economic history, and here is an excerpt:

All of these amount to the same core point, those who reap the private benefits of slavery are content with their gains even though they come at a larger social cost and they will work to find ways to drive a wider wedge between the two by shifting costs onto other parties. Hence, slavery as pollution.

Inventions that didn’t change the world

Have you ever learned about an amazing invention–whether it was the Baghdad battery or the ancient Roman steam engine or Chinese firecrackers–and wondered why it didn’t do more to change the world? In this podcast, we examine a selection of curiosities and explore hypotheses for why their inventors didn’t use them to full effect.

We move VERY quickly through a range of fascinating examples and hypotheses, and therefore leave a lot up to discussion. We hope to see your thoughts, feedback, and additions in the comments section!

For any invention that you want to learn more about, see the links below:

Knossos’ toilets

In the 2nd millennium BC, a “palace” (now thought to be a building that served as administrative, trade, and gathering hub) had running-water toilet flushing. Much like the Roman Cloaca Maxima, likely a HUGE public-health benefit, but basically died out. Does this show that military protection/staving off the “Dark Ages” was the only way to maintain amazing inventions?


The Nimrud lens

Whether it was a fire-starter, a magnifying glass, or (for some overeager astronomy enthusaists), the Neo-Assyrian ground-crystal Nimrud lens is an invention thousands of years out of place. While the Egyptians, Greeks, and Romans all used lenses of different sorts, and glass-blowing was certainly popular by the 1st century BC in Roman Egypt, no glass lenses were made until the Middle Ages and the potential scientific and engineering uses of lenses–that can hardly be understated even in their 16th-to-18th-century applications–had to wait another couple millennia. Many devices like the Baghdad battery and Antikythera device are heralded for their possible engineering genius, but this seems like a simple one with readily available applications that disappeared from the historical record.

Hero of Alexandria’s steam engine

In the 1st century AD, Hero was a master of simple machines (that were mostly used for plays) and also invented a force pump, a wind-powered machine, even an early vending machine. However, he is likely most famous for his Aeolipile, a rotating steam engine that used heated water to spin an axle. The best attested use of this is for devotion to the divine and party tricks.

The ancient mechanical reaper

Ancient Gallo-Romans (or just Gauls) invented a novel way of grain harvesting: rather than using sickles or scythes, they used a mechanical reaper, 1700 years before Cyrus McCormick more than tripled the productivity of American farmers. This antiquated device literally but the cart before the oxen and required two men to operate: one man to drive the beasts, and another to knock the ears off the stalk (this reaper was obviously far less sophisticated than McCormick’s). This invention did not survive the Volkswanderung period.

Note: the horse collar (which allowed horses to be used to plow) was invented in 1600-1400 BC in China AND the Levant, but was not applied widely until 1000 AD in Europe.


Madhav, an Indian doctor, compiled hundreds of cures in his Nidana, including an inoculation against smallpox that showed an understanding of disease transmission (he would take year-old smallpox-infected flesh and touch it to a recently made cutaneous wound). However, the next 13 centuries did not see Indian medical understanding of viruses or bacteria, or even copied techniques of this, development.

At least, thank god, their methods of giving nose jobs to those who had had their noses cut off as a punishment survived:

The Chinese:

List of all chinese inventions:


Gunpowder was discovered by Chinese alchemists attempting to discover the elixir of life (irony, no?)

(maybe a good corollary would be Greek fire, which was used effectively in naval warfare by the Byzantines, but which was not improved upon and the recipe of which is still secret:


The Chinese invented the printing press possibly as early as the 6th century. However, unlike the explosion of literacy seen in much of Europe (particularly Protestant Europe–see our last podcast), the Chinese masses never learned to read. In fact, in 1950 fewer than 20% of Chinese citizens were literate. Compare this to Europe, where some societies saw literacy rates of as high as 90% (Sweden, Male population) in some societies within a few centuries of the introduction of the printing press. Why? There may be several reasons–cultural, religious, political–but in our opinion, it would have to be the characters: 100,000 blocks were needed to create a single set.

They also invented pulped paper by the 2nd century BC:

The compass

Invented by 200 BC for divination and used for navigation by the Song dynasty; despite this and the availability of easily colonizable islands within easy sailing distance, the Chinese did not colonize Indonesia, Polynesia, or Oceania, while the Europeans did within the century after they developed the technology and first sailed there.

The rudder

While they did not invent the rudder, they invented the “medial, axial, and vertical” sternpost rudder that would become standard in Europe almost 1,000 years before it was used in Europe (1st century AD vs 11th century).

Natural gas

The Chinese discovered “fire wells” (natural gas near the surface) and erected shrines to worship there.

They even understood their potential for fuel, but never developed beyond primitive burning and bamboo piping despite having advanced mining techniques for it by the 1st century BC.

Chinese miscelleni:

Hydraulic powered fan:

Cuppola furnace for smelting and molding iron:

Coke as a fuel source:

Belt-drive spinning wheel:

The Precolumbian wheel

The pre- and early Mayans had toys that utilized primitive wheels, but did not use them for any labor-saving purpose (even their gods were depicted carrying loads on their backs). This may have been because scaling up met with mechanical difficulties, but the potential utility of wheels in this case with a bit of investment literally sat unrealized for centuries.

The Tucker:

The following book contained some of our hypotheses:


The rest of our hypotheses were amalgamated from our disparate classes in economics and history, but none of them are our own or uncommon in academic circles. Thanks for listening!

The Deleted Clause of the Declaration of Independence

As a tribute to the great events that occurred 241 years ago, I wanted to recognize the importance of the unity of purpose behind supporting liberty in all of its forms. While an unequivocal statement of natural rights and the virtues of liberty, the Declaration of Independence also came close to bringing another vital aspect of liberty to the forefront of public attention. As has been addressed in multiple fascinating podcasts (Joe Janes, Robert Olwell), a censure of slavery and George III’s connection to the slave trade was in the first draft of the Declaration.

Thomas Jefferson, a man who has been criticized as a man of inherent contradiction between his high morals and his active participation in slavery, was a major contributor to the popularizing of classical liberal principles. Many have pointed to his hypocrisy in that he owned over 180 slaves, fathered children on them, and did not free them in his will (because of his debts). Even given his personal slaves, Jefferson made his moral stance on slavery quite clear through his famous efforts toward ending the transatlantic slave trade, which exemplify early steps in securing the abolition of the repugnant act of chattel slavery in America and applying classically liberal principles toward all humans. However, this very practice may have been enacted far sooner, avoiding decades of appalling misery and its long-reaching effects, if his (hypocritical but principled) position had been adopted from the day of the USA’s first taste of political freedom.

This is the text of the deleted Declaration of Independence clause:

“He has waged cruel war against human nature itself, violating its most sacred rights of life and liberty in the persons of a distant people who never offended him, captivating and carrying them into slavery in another hemisphere or to incur miserable death in their transportation thither.  This piratical warfare, the opprobrium of infidel powers, is the warfare of the Christian King of Great Britain.  Determined to keep open a market where Men should be bought and sold, he has prostituted his negative for suppressing every legislative attempt to prohibit or restrain this execrable commerce.  And that this assemblage of horrors might want no fact of distinguished die, he is now exciting those very people to rise in arms among us, and to purchase that liberty of which he has deprived them, by murdering the people on whom he has obtruded them: thus paying off former crimes committed against the Liberties of one people, with crimes which he urges them to commit against the lives of another..”

The second Continental Congress, based on hardline votes of South Carolina and the desire to avoid alienating potential sympathizers in England, slaveholding patriots, and the harbor cities of the North that were complicit in the slave trade, dropped this vital statement of principle

The removal of the anti-slavery clause of the declaration was not the only time Jefferson’s efforts might have led to the premature end of the “peculiar institution.” Economist and cultural historian Thomas Sowell notes that Jefferson’s 1784 anti-slavery bill, which had the votes to pass but did not because of a single ill legislator’s absence from the floor, would have ended the expansion of slavery to any newly admitted states to the Union years before the Constitution’s infamous three-fifths compromise. One wonders if America would have seen a secessionist movement or Civil War, and how the economies of states from Alabama and Florida to Texas would have developed without slave labor, which in some states and counties constituted the majority.

These ideas form a core moral principle for most Americans today, but they are not hypothetical or irrelevant to modern debates about liberty. Though America and the broader Western World have brought the slavery debate to an end, the larger world has not; though countries have officially made enslavement a crime (true only since 2007), many within the highest levels of government aid and abet the practice. 30 million individuals around the world suffer under the same types of chattel slavery seen millennia ago, including in nominal US allies in the Middle East. The debates between the pursuit of non-intervention as a form of freedom and the defense of the liberty of others as a form of freedom have been consistently important since the 1800’s (or arguably earlier), and I think it is vital that these discussions continue in the public forum. I hope that this 4th of July reminds us that liberty is not just a distant concept, but a set of values that requires constant support, intellectual nurturing, and pursuit.
