Computer souls

[A kitchen table conversation between a parent and a child]

Daddy, if my computer burned up in a fire, would it still compute? No, Mary. Programs don't simply run by themselves. They depend upon extremely complicated hardware and software. If your computer burns up in a fire, there would be no hardware and no software with which to run your favorite programs. But I've used my computer for a long time. I've grown emotionally attached to it. It makes me sad that it won't actually compute if it were to be destroyed. Doesn't my computer have a soul that continues running my programs somewhere else after my computer burns up on Earth? I'm sorry, Mary. There is no computer heaven and there is no computer soul. There is no evidence of either of these. But we can't prove that it won't keep computing after it burns up in a fire, right? No. Sorry, Mary. Without hardware and software, no computing will happen. The ashes of your burned up computer would lack any systematic structure. They certainly lack the complex organization required to run programs. It is impossible for any computation to occur without the hardware and the software intact. Your claim that a computer would keep computing even though it is completely destroyed is an extraordinary claim that would require extraordinary proof. We have no such proof whatever. But Lisa Jenkins says that burned up computers do keep computing. She says that you only need to have faith and that no one can disprove that burned up computers live on in a parallel world. She says destroyed computers keep working, but not in a physical way. She goes to a special building on Sunday where thousands of people all believe that computers keep computing even after they are completely destroyed. No, Mary. The same thing happens to computers as happens to your own body. As you know, when your body dies, your entire body rots, including your brain. As you know, when your brain is rotted, you don't have any more thoughts because there is no intact functional neural structure anymore, and therefore no basis for any continuing thoughts. Oh, daddy! It's not the same! Yes, I know that when my body dies, it will be impossible for me to think anymore. My computer is different, though. I just can't believe that my amazing computer would stop computing just because it gets completely destroyed! Don't try to compare my beautiful computer to a human brain! It's not a matter of what you want to believe, my child. It's a matter of what actually happens in the real world. You can continue using your computer for now and loving the way it works, but it would be unhealthy to believe that it would keep computing even if it was destroyed. As a parent, it's my job to level with you regarding difficult topics like this. I'm so sorry.

Refusing to shuffle quietly out the door, one local journalist stands tall –

Post-2008-election, I felt as though our country was finally regaining consciousness. I felt hope and optimism rise and my cynicism roll back ever-so-slightly, breezes of fresh thought dispersing the haze. As my vision returned, I could once again engage in conversations that did not fizzle into frustrated non-verbal noise. I began to see glimpses of a cultural evolution of thought through the wider population. Just glimpses, but they were there, I know it. I felt the whoosh of tired air as egos fat with imaginary power based on non-existent wealth were deflated by the reality of financial correction. I smiled as the facade of organized evangelical religion cracked under self-made storms of condescending hypocrisy. I grinned with sincere joy every time I heard new dialogue about race and culture in the wake of electing our first minority president. All in all, I saw daily reminders that people, all of us, are truly equal underneath all the cultural trappings. Eye contact became pleasant again. The obvious human connections we share - that we all love and laugh and hurt and seethe and wonder and sigh and ache and even hate - I could see those commonalities beginning to connect us again. We argue and bicker, we debate and discuss, we learn, we teach, we manage, we create, we err and we try. We help, we care, sometimes we dismiss. We each react to information and situations from our own perspectives, wrought upon our own personalities by our own life stories. But we seemed to be listening to each other again. I hoped anew that as a culture, we were learning that all of those life stories matter. That each one of us brings a unique self to the cultural table and that even when we strenuously disagree, we do not dismiss each other simply because of it. Silly me. Last week, a friend of mine was fired. Not a big deal, you might think, as people have been laid off in record numbers (including myself) over the past months of economic strife. Sure, a big deal for him, maybe. But, well, welcome to the masses. Except that this friend represented something we cannot afford to lose, and his firing rips further into the frayed fiber of our local democracy. Sadly, too many will dismiss the loss as no big deal - for the exact reason we so desperately needed Sylvester Brown to stay.

What if there were animals that were genetically close to modern humans, but startlingly different?

What if there were animals that looked very much like modern human animals and almost identical genetically, yet they differed from us in notable ways? Would their discovery shock and horrify people? Quite likely. Wouldn't it also make many people start thinking deeply about the fact that modern humans themselves are animals? You'd hope so. Wouldn't this discovery make us intensely curious about our own origins? Remains to be seen. What follows is a true story. The evidence is overwhelming that large numbers of Neanderthals roamed Eurasia for 200,000 years. The evidence is also clear that Neanderthals differed from the modern humans in genetically small but socially and physiologically significant ways. This incredible story can be found in the October 2008 edition of National Geographic, in an article entitled "Last of the Neanderthals." This article is a must read article for anybody who wants to peer into the not-so-distant past in order to learn about his or her bipedal cousins. The article is filled with incredibly lifelike modeling of the Neanderthals. It is also filled with detailed information about Neanderthal physiology, as well as clues to Neanderthal lifestyle.

Did our brains grow big because we learned to cook?

Consider that 60% of the energy expended by a resting baby is consumed by the baby's brain.  A resting adult brain uses 25% of its energy.  Compare this to the average ape brain, which uses only 8% of the apes energy.  In short, having a big brain requires a lot…
