George Cantor, Ludwig Boltzmann, Kurt Gödel, and Alan Turning: “The Vertigo of the Modern”

A roller coaster ride for your mind — have a look at this documentary, “Dangerous Knowledge,” on the work of Georg Cantor, Kurt Gödel, and Alan Turing. YouTube changes its offerings for all sorts of reasons, so you might need search a bit if this video link goes bad. At one point, the narrator uses a most memorable phrase to characterize what it is to be “modern”— I can only paraphrase:

The vertigo of the modern: the whirlpool of thinking about thinking about thinking about thinking . . .

Plato - Crito

After having been unjustly convicted of the bogus charges brought against him in that most infamous and influential of trials, Socrates was asked to propose a penalty for himself. Defying everyone's expectations (exile, paying a fine, delivering a public apology, etc.), Socrates claimed he should be rewarded with free room and board at the Prytaneum. This response upset the Athenians so much that an even greater number than those who had originally found him guilty decided the proper sentence should now be death.In the Crito, and against all sorts of arguments—moral, prudential, political, philosophical—urging him to escape this unjust punishment,… [...]

The Philosophy of Christopher Nolan

Ever since I first watched Memento and its fascinating exploration of the philosophical question of personal identity as constituted by memory through time, film director Christopher Nolan has been on my radar. And, Insomnia aside, he has consistently managed to set the bar higher and higher to the point where he stands on a category of cinematographic and philosophical genius all by himself.In addition of being a master of character development, non-linear storytelling and building hair-raising suspense—not to say anything about the pure aesthetic beauty of his films—Nolan is a director of big ideas. There's virtually no film in which he… [...]

Voltaire - Candide

The philosophical problem of evil—the question of how the existence of unnecessary suffering is possible in a world created and sustained by an all-powerful, all-knowing and benevolent deity—has vexed theologians and philosophers for millennia.Apologists have attempted to vindicate God's goodness in various versions of what is known as theodicy. One of the most famous was articulated by the Enlightenment polymath Gottfried Wilhelm Leibniz. Given that he thought the existence of contingent beings requires an explanation that is itself not contingent, Leibniz deployed a really clever argument to prove the metaphysical necessity of the existence of God. Since God was for… [...]

Arrow - A Celebration of Love

Life is hard enough as it is. Existence, in many ways, is suffering. Obviously, some have it much worse than others, and that matters, but at some point in our lives we all experience pain, disease, loss, betrayal. We struggle with existential angst, with the fear of meaninglessness, with questions of character, with the impending coming of oblivion. We struggle to pay rent, to put food on the table, and to have enough energy at the end of the day to make a positive difference in the world.And we don't all find love. Few things make the loneliness of existence… [...]

If 'Despacito' Were Written by an Evo-Devo Biologist

And the following parody of 'Despacito' is just such an instance... [...]

James Baldwin Debates William F. Buckley

James Baldwin, the great essayist, poet, civil rights activist, writer and orator, would have turned 93 this week. In order to commemorate the importance of his memory and legacy, we are showcasing today the very famous Cambridge debate in which—while surrounded by an overwhelmingly white audience—he courageously and adeptly defended the proposition that “The American Dream is at the expense of the American negro” against the influential conservative writer William F. Buckley, Jr.Prior to this debate, Buckley had made his reputation as a leading American conservative, at least partly, through his writings opposing the civil rights movement and desegregation, and by… [...]

Genius of the Ancient World - Socrates

Few figures have been more important and influential in the history of civilization than the ancient Greek philosopher Socrates. And it's not simply that he was a philosopher either. Despite the importance of the intellectual contributions made by his predecessors, and despite the vast differences between them (just think Thales, Anaximander, Pythagoras, Parmenides, Heraclitus, Democritus, etc.), virtually all philosophers who preceded him were ultimately consigned to the category of Pre-Socratics.So what exactly was so special about Socrates that it would be he, and not any of his forerunners, who would be generally recognized to be the first master of philosophy?… [...]

The Presocratics

Anyone who's ever contemplated Raphael's celebrated painting The School of Athens knows that the painting centers, quite literally, around Plato and Aristotle (the former pointing up toward his transcendent Realm of the Forms, while the latter attempts to ground his understanding of reality on a much more naturalistic conception). A quick glance also reveals a few other obvious personalities: Socrates, Diogenes the Cynic, Pythagoras, and Euclid (or perhaps Archimedes?). But if you look even closer, you can see that this painting is also paying homage to the Presocratics, those thinkers who dared to imagine the cosmos might be intelligible to… [...]

President Obama's Farewell Address

As his presidency sadly comes to an end, President Obama delivered last night what is sure to become one of the most powerful and memorable speeches in his already admirable history of powerful and memorable speeches.In a time when democracy, justice, freedom, equality and human rights have come under threat in America—as a right-wing administration inspired by unabashed hatred, divisiveness, racism, xenophobia and greed prepares to take office—President Obama's message is a sober and thoughtful reminder that this experiment in self-governing is not a foregone conclusion but a process that requires permanent work, vigilance and cooperation.Thank you for being an… [...]

John Berger - Ways of Seeing

Art critic John Berger's recent death has left a huge void in the world of art appreciation. While his career prompted numerous controversies and instances of outrage and public condemnation, Berger's attacks on what sometimes amounts to the condescending and elitist attitude of his own profession helped popularize the appreciation of art. His 1972 BBC documentary series Ways of Seeing, as well as its subsequent eponymous book, helped bring the world of thoughtful art appreciation to an entire generation of people who may have otherwise never gotten interested in the fine arts. Unlike conventional forms of art criticism and appreciation—which tend… [...]

EVIL: Democrats changed house rules so they could smear President Trump repeatedly during impeachment sham as a racist and "White Supremacist-in-Chief"

The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size.

This helps them rapidly take off when escaping predators. [...]
