And here we see Jean-Paul Sartre (1905-1980), one of the greatest philosophers of the 20th century. He embodied the Existentialist movement, which argued that there is no authority or meaning in existence outside of what we make of it. Whether we accept or reject this idea, or find it hopeful or depressing, Sartre’s philosophy admirably

This 17th-century design would make a perfect tattoo, except the meaning would say something pitiable about the wearer. It is a rose with the Latin word “CAUTE” beneath. The rose meant secrecy, and _caute_ means “cautiously.” The person who used this sign, Baruch de Spinoza (1632-1677), did so because he had to constantly keep his

If you haven’t read about the Tulsa Race Massacre of May 31/June 1, 1921, I recommend learning about it. One of the worst race-based killings in American history, it illustrates how simmering bigotry, fear, and mob violence can erupt quickly and cause lasting harm. It also showcases the critical role that historical memory plays in

Here come two points about human evolution – the first is one that I imagine is not surprising to you, but the second may be, and might make you wince.First, the animal in this photo is not an ancestor of us Homo Sapiens. We did not evolve from apes but share a common progenitor that

When does the story of Alice actually intersect with rabbits? In the case of evolutionary history — and a failed attempt at biological warfare in Australia.I can think of nothing that demonstrates the process of biological evolution more clearly than viruses. Because their genomes are so small, their genetic mutation rates produce a rapid effect.

Ancient Hindu and Middle Eastern Islamic surgeons knew a lot about eye cataracts, relatively speaking, and one important medical text, called the _Sushruta Samhita_, exists from about 1500 years ago that detailed how a specialist might remove them from a suffering patient. As this manuscript illustration shows, the knowledge from India made its way to

The bodhisattvas in the Mahayana tradition of Buddhism are those who believe that until everyone is free, no one is free. Although enlightened, they willfully choose to forgo nirvana, and instead allow themselves to be reincarnated into this mortal coil.

Today’s social-media aficionados take a lot of personality tests that we know are pure rot, like “what your birth crystal says about the way you treat your pets” or “what your quarantine eating habits reveal about your financial investment patterns.” The bust pictured here reflects similarly outlandish claims from a century and a half ago,

Carved around 1600 in Elizabethan England, the exquisitely crafted masterpiece became famous almost immediately – Shakespeare even had one of his characters in _Twelfth Night_ (1601) claim that a piece of paper was so large that it was “big enough for the
