Unfortunately, you have a brain tumor. You don’t know it yet. Your doctor doesn’t know it yet. But you are beginning to have symptoms. The tumor is pressing on surrounding brain tissue and causing you develop a number of delusional beliefs. You believe you are the best swimmer in the world. You believe that dogs and cats are aliens. You believe that you invented the apostrophe. You also, as it happens, believe that you have a brain tumor.
So, you have a brain tumor. You believe you have a brain tumor. And the cause of your believing that you have a brain tumor is the brain tumor that you have. So, when the doctor diagnosis you with a brain tumor, are you entitled to say, “I know, right!”?
If the belief that you have a brain tumor is caused by the same thing that causes you to believe you invented the apostrophe, I think most of us would say that you don’t, in fact, know that you have a brain tumor – even if you believe it and it’s true. But it’s difficult to see why. It has something to do, probably, with justification.
Implicitly or explicitly philosophers, epistemologists to be more specific, define knowledge as justified true belief. Knowledge, then, is a kind of belief. What kind? Well, of course, the belief has to be true to count as knowledge. But it also has to be justified. If you correctly guess what the weather will be like tomorrow, we shouldn’t say that you knew it. If you predict the weather accurately using instruments and satellite maps, then you may have had or have knowledge. The brain tumor example raises questions about how justification works. There’s something wrong with the connection the belief has to why you believe it. It echoes an even more famous puzzle – the Gettier problem. Read more »

“Taxi to Bethlehem, taxi to Jericho!” the man at a tourism kiosk is shouting, as I make my way from the tram to Jaffa Gate, known also as Hebron Gate, to Muslims as “Bab al Khalil,” or “door of the friend,” named after Hebron where the prophet Ibrahim/Abraham (Khalil al Allah “God’s Friend”) is laid to rest. Of significance too, is the association of this gate with King David’s (prophet Dawud’s) chamber, for followers of the three Abrahamic faiths: the crusaders named it “King David’s Gate.” It is one of the seven main stone portals of the walled city of Jerusalem.
Calls for a Manhattan Project–style crash effort to develop artificial intelligence (AI) technology are thick on the ground these days. Oren Etzioni, the CEO of the Allen Institute for Artificial Intelligence, recently issued such a call on 

Fans are the people who know the quotes, the dates of publication, the batting averages, the bassist on this album, the team that general manager coached before. I am not a fan. Don’t get me wrong. I’m full of enthusiasms. But I can’t match you statistic for statistic. I haven’t read the major author’s minor novel. I don’t care who the bassist was. You win. I’m an amateur.
When I watched the 2019 documentary on Apollo 11, it carried me back not to the summer of 1969, when it happened, but to the mid-1980s, when I was an undergrad. I was eight when Apollo 11 launched; of course I was aware of the space program and the moon landings, but I don’t have any memories of everyone gathering around to watch those first steps on another world. My parents weren’t particularly interested, and I don’t remember being caught by the spirit of the times myself.
cinematic representations of Muslims. Stage One features stereotyped figures (the taxi driver, terrorist, cornershop owner, or oppressed woman). Stage Two involves a portrayal that subverts and challenges those stereotypes. Finally, Stage Three is ‘the Promised Land, where you play a character whose story is not intrinsically linked to his race’. Does 
Our expectations sculpt neural activity, causing our brains to represent the outcomes of our actions as we expect them to unfold. This is consistent with a growing psychological literature suggesting that our experience of our actions is biased towards what we expect. —

My friend does not use punctuation when he texts, so there is a stream-of-consciousness quality to much of his communications. According to the fine folks at 
The right to own guns is typically justified by the fundamental right to self-defense against bad guys, either our fellow citizens or the state itself if it were to turn tyrannical. Both of these have a superficial appeal but fail in obvious ways. Guns are an effective means of defending oneself against bad guys only so long as they don’t have guns too (because being equally armed doesn’t add up a defense against those who can pick and choose their moment of aggression). Civilians with guns are also ineffective against the armies and ruthless terroristic violence of a truly tyrannical regime.
So goes a popular snippet from Seinfeld. In a 2014 article in The Guardian titled “Smug: The most toxic insult of them all?” Mark Hooper opined that “there can be few more damning labels in modern Britain than ‘smug.'” And CBS journalist Will Rahn declared, in the wake of Donald Trump’s 2016 electoral victory, that “modern journalism’s great moral and intellectual failing [is] its unbearable smugness.”
