I was recently invited to write an essay for a promising new web site that launches today, called Being Human. It’s all about what it means to be Homo sapiens, and I chose to focus on our brain, which is so fundamental to our unique place in the natural world. In fact, we like to think of ourselves as our brains. You could, after all, imagine yourself as just a brain in a vat. It might be hard to manage, but if someone could figure out the right liquids to put in the tank and the right wires to stick into it, it “ought” to work. Hence, The Matrix.

This is actually a new notion, and in my essay, I take a look at our ideas about the brain over the past couple thousand years. Check it out.

Being Human, October 10, 2012

Hilary Putnam is not a household name. The Harvard philosopher’s work on the nature of reality, meaning, and language may be required reading in graduate school, but Putnam’s fame hasn’t extended far beyond the academy. But one of Putnam’s thought experiments is familiar to millions of people: what it would be like to be a brain in a vat?

Here’s how Putnam presented the idea in his 1981 book, Reason, Truth, and History:

Imagine that a human being…has been subjected to an operation by an evil scientist. The person’s brain…has been removed from the body and placed in a vat of nutrients which keeps the brain alive. The nerve endings have been connected to a super-scientific computer which causes the person whose brain it is to have the illusion that everything is perfectly normal. There seem to be people, objects, the sky, etc.; but really, all the person…is experiencing is the result of electronic impulses travelling from the computer to the nerve endings.

Last month I blogged about the unsavory practices of French scientists who unveiled a study purporting to show that genetically modified corn and herbicide cause cancer in rats. Not only was the study weak, but the scientists required reporters to sign an oath of secrecy to see it in advance. As I explained to the NPR show On the Media, this strategy raised the odds that all those pesky questions about statistical significance from meddling outsiders would be absent from the first wave of reporting.

In Nature today, Declan Butler continues his great reporting on the affair, unearthing additional disturbing parts of the story. My favorite was this passage from the agreement that some reporters–incredibly–agreed to sign:

“A refund of the cost of the study of several million euros would be considered damages if the premature disclosure questioned the release of the study.”

Who knew that doing basic science reporting could land you catastrophically in debt? Well, aside from Simon Singh…
