Stephanie Canizales on the human tragedy of undocumented and unaccompanied migrant youth in the US.
Six months or so ago, I had a fascinating interview/discussion with Stephanie Canizales about her book, Sin Padres, Ni Papeles, which described her five year PhD project interviewing young people who had migrated from Central America as undocumented and unaccompanied minors in pursuit of a better future. These children were sent by their parents because they had no other choice, either to protect their lives from violence or because they had no means to support them at home. Once these children arrived in the US they were met by either impoverished relatives who often couldn’t support them. With no access to education or any legal means of supporting themselves they were forced to take low-wage jobs just to survive. I believe our society should be judged not by how well we keep people out, but how well we treat people when they are here. The story of these children is heart wrenching, and raises many complex issues, which may challenge previous notions you may have about such things as child welfare laws, about how we treat these young people who were driven here not out of choice, but through necessity, and who our society largely abandons once they arrive. Because of the vicissitudes of international affairs and other unexpected factors, we were not able to release this dialogue before now. But perhaps there could be no more opportune time to address this issue. Kilmar Armando Abrego Garcia came to this country as a 16 year old, a minor sent by his family to protect him from local gangs. In the intervening 14 years in the United States he was never charged or convicted of a crime, just as he had never been so charged or convicted in his home country of El Salvador. He had a job, and had several children with his US citizen wife. Nevertheless, he was recently illegally deported, without any trial, back to a maximum security prison in El Salvador, leading to a vigorous public debate. During the public discussions, Kilmar, and other illegal immigrants have been vilified for the acts of desperation that led them to enter the US illegally. But very little has been discussed about the harrowing challenges people like Kilmar met when they arrived here, alone, as children. My discussion with Stephanie will hopefully add a new dimension to the current public debate on this issue, focusing on real people rather than statistics, and on both the causes for the recent illegal migration to the US, and also the actual impact both on the country and on the immigrants while they live in the US. In so doing, I hope this expands your perspective of this complex problem, which is, after all, one of the purposes of this podcast, and of the Origins Project Foundation.As always, an ad-free video version of this podcast is also available to paid Critical Mass subscribers.

Ricky Gervais: Hall of Fame episode: Comedy, Philosophy, Religion and Science
The Origins Podcast began with a bang, a Big Bang. Over the first month of our recording, we traveled to two continents, and 4 cities and recorded 16 episodes in 22 days. It was a whirlwind, and one of the most amazing experiences I can recall. While in London, we took advantage of the amazingly gracious acceptance by Ricky Gervais to appear on the podcast. It was a day I will always remember. Ricky had appeared in our film, The Unbelievers, which followed me and Richard Dawkins around the world. Gus and Luke Holwerda, who directed and filmed that movie helped create The Origins Podcast, and for the first year, filmed all the episodes. Ricky graciously agreed to appear in front of their cameras one more time, and joined us at what was then New College of Humanities, where I was a visiting Professor. From the moment he arrived, it was clear it was going to be great. As he had been when we filmed The Unbelievers Ricky claimed to be nervous and was worried he would appear ignorant. He needn’t have worried. Maybe that is one of the reasons he is so good at what he does, because he worries about rising to the challenge. We discussed his early life, his love of science, his early interest in biology and then philosophy, then the science of comedy, the comedy of religion, and the need for free speech. He then proceeded to demand a mind-bending, personal science lesson from me. It was amazing. He was amazing. Enjoy this, our first rebroadcast of a classic Origins Podcast Episode that is worth watching once again. Enjoy.
