Jefferson and the Source of Human Rights
Thomas Jefferson’s deist conception of natural rights and popular sovereignty contrasts sharply with modern claims that American rights derive directly from a personal, interventionist God. Image by Zoe Sankey.
Jefferson and the Source of Human Rights
Anticipating the 250th anniversary of America’s Declaration of Independence, speaker of the House of Representatives Mike Johnson recalled: “We boldly proclaimed the self-evident truth that our rights do not come from government, they come from God Himself.” In 2018, President Trump likewise declared: “Our rights are not given to us by man; our rights come from our Creator.” And defence secretary Pete Hegseth recently stated: “Today we gather to recognize that our rights here in this great...
ESA’s Plato Mission Can Reveal Details About ‘Alien’ Worlds And Whether Our Solar System Is Unusual
When detections push the limits of current capabilities, one has to ponder the reliability of the findings. Hence it is reassuring when independent teams, using different telescopes, instruments and computer codes, arrive at the same conclusions Barnard's Star is a small, dim star, of the type that astronomers call red dwarfs. Consequently, even though it is one of the stars closest to Earth, such that its light takes only six years to get here, it is too faint to be seen with the naked eye.
Four small planets discovered around one of the closest stars to Earth-an expert explains what we know
Barnard's Star is a small, dim star of the type that astronomers call red dwarfs. Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it is too faint to be seen with the naked eye. Now, four small planets have been found orbiting the star. Teams in America and Europe achieved this challenging detection by exploiting precision instruments on the world's largest telescopes.
O que sabemos sobre os quatro pequenos planetas recém-descobertos em órbita da Estrela de Barnard
A Estrela de Barnard é uma estrela pequena e de brilho tênue, do tipo que os astrônomos chamam de anãs vermelhas. Consequentemente, embora seja uma das estrelas mais próximas da Terra, de modo que sua luz leva apenas seis anos para chegar aqui, ela é muito fraca para ser vista a olho nu. Agora, quatro pequenos planetas foram descobertos orbitando a estrela.

Podcast #233: Creating a Safe Space for ‘Problematic’ Women
As many regular listeners will know from her previous appearance on the Quillette podcast, Meghan Daum is a New York-based book author, writing coach, social-media maven, and, more recently, the woman behind a new set of events, known as The Unspeakeasy—where “intellectually curious women from everywhere on the political spectrum can talk honestly about complex issues and ask meaningful questions to which there are no easy answers.” Meghan joined us to talk about The Unspeakeasy and a dozen...
China, the West, and The Three-Body Problem
A review of the trilogyThe Remembrance of Earth’s Pastby Liu Cixin (The Three-Body Problem, 2006; the Dark Forest, 2008; Death’s End, 2010), 1472 pages, Chinese edition, Chongqing Publishing Group; English edition, Tor Books. Books 1 and 3 were translated from the Chinese by Ken Liu; book 2 by Joel Martinsen. Contains spoilers. The aliens of the planet Trisolaris have a big problem: their world is locked in an unstable orbit around three stars.
Vaccine Hesitancy and the Covid Pandemic
When COVID hit in the winter of 2020, hospitals were overflowing with the sick and dying. Public health experts worried that we’d be isolating for years because, although vaccines were possible, none had ever been developed in fewer than four years. Yet, within weeks of the identification of the virus’s genetic structure, two companies had settled on the basic frameworks for mRNA vaccines, which were then developed on an accelerated timeline.
A Different Way of Fighting
What follows is the eighteenth instalment of The Nations of Canada, a serialized Quillette project adapted from Greg Koabel’s ongoing podcast of the same name. From early days, religion had been an awkward subject for Samuel de Champlain. On the one hand, any religious support for the exploration and colonization of Canada would have had to come from the Catholic Church—the official religious body of the French state.
You Can’t Buy an Authentic Self

Johann Blumenbach: The First Race Scientist
The concept of race, we are often told, is a social construct with no basis in biological reality. Some have argued that it was invented by white Europeans for the express purpose of constructing a racial hierarchy in order to justify slavery. According to cultural critic Kenan Malik, “Racism gave birth to race. The ancestors of today’s African Americans were not enslaved because they were black.
Not Everyone Who Disagrees with You Is An ‘Uncle Tom’
Uncle Tom. Aunt Jemima. Judas. Aunt Lydia. Kapo. Self-hating Jew. Banana. Oreo. Quisling. Traitor. Sell-out. These are all pejoratives used to refer to someone accused of betrayal. Judas betrayed Jesus for money; Aunt Lydia betrays women for power; Uncle Tom betrays black people for his own protection. Actually, I’m not sure what Uncle Tom betrays black people for.
Rediscovering the Meaning of Diversity: Lessons from Generation X
Amidst the tribalized culture-war rhetoric that pits Baby Boomers (born 1946–64) against much younger Millennials (1980–94) and members of Generation Z (1995–2012), my own cohort—Generation X (1965–79)—often gets sidelined. That’s too bad, because our unique historical vantage point could help the United States bridge its generational differences.
The Genocidal Imagination
Give me absolute control Over every living soul. ~Leonard Cohen, “The Future” To understand what happened in southern Israel on October 7th, 2023, in Iraq and Syria between 2014 and 2017, and what will inevitably reoccur elsewhere, we must return to the godfather of torment, Donatien Alphonse François de Sade. This debauched 18th-century aristocrat, a product of the decaying Ancien Régime, demands to be taken at his word.
Why Not Polygamy: the Debate on Legalization
In the 19th century, Mormon polygamy shocked the American public, and Utah was only granted statehood on the condition that it prohibit it forever. Today, 80 percent of Americans still think it’s wrong according to a 2020 Gallup poll, but that number is trending downwards. In Canada, a 2018 Ipsos poll found that 36 percent of respondents approved of decriminalizing polygamy. Polyamory and polygamy are both gaining mainstream media respect, and are often treated as equivalent, but they aren’t.
Newly found exoplanet GJ 367b is too hot to be habitable
It's possible that GJ 367b was once a giant planet with a vast, gaseous envelope, like Neptune, researchers believe Keele (UK): As our Solar System formed 4.6 billion years ago, small grains of dust and ice swirled around, left over from the formation of the Sun. Through time, they collided and stuck to each other. As they grew in size, gravity helped them clump together. One such rock grew into the Earth on which we live.
A new exoplanet: meet GJ 367b, an iron planet smaller and denser than Earth
As our Solar System formed 4.6 billion years ago, small grains of dust and ice swirled around, left over from the formation of the Sun. Through time, they collided and stuck to each other. As they grew in size, gravity helped them clump together. One such rock grew into the Earth on which we live. We now believe that most of the stars in the night sky are also orbited by their own planets.

Astronaut Sally K. Ride's legacy – encouraging young women to embrace science and engineering
On June 18, 1983, 35 years ago, Sally Ride became the first American woman to launch into space, riding the Space Shuttle STS-7 flight with four other crew members. Only five years earlier, in 1978, she had been selected to the first class of 35 astronauts – including six women – who would fly on the Space Shuttle. Much has happened in the intervening years.
NASA planet hunter on its way to orbit
NASA’s Transiting Exoplanet Survey Satellite (TESS) launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life. TESS, which is expected to find thousands of new exoplanets orbiting nearby stars, lifted off at 6:51 p.m. EDT Wednesday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. At 7:53 p.m., the twin solar arrays that will power the spacecraft successfully deployed.
NASA launches satellite 'TESS' in hunt for exoplanets
Previous generations have looked up at the stars in the night sky and wondered whether they are also orbited by planets. Our generation is the first to find out the answer. We now know that nearly all stars have planets around them, and as our technology improves we keep finding more. NASA’s newest satellite, TESS (the Transiting Exoplanet Survey Satellite), scheduled for launch on April 16, 2018, will extend the hunt for small, rocky planets around nearby, bright stars.
