I read this story in The Guardian this morning, about a paralyzed man who is able to control a robotic arm with his mind. Sounds like science fiction, but doctors have tapped into his brain waves using a brain implant called "BrainGate" and electrodes attached to his sensory motor cortex, which produces the neural signals that say "move!"
A computer deciphers the brain waves, and in turn moves the objects in the manner requested by the patient. In one experiment, he was able to remove sweets from one person's hand and drop them in another. He's been using the computer game Pong to improve his skills. Eventually, scientists hope to make it possible for him to control the lights, his phone, and other devices.
This sounds like the ultimate couch potato gear, but it will likely be life altering for thousands of paralyzed people whose brain cortex works fine, but whose spinal cord is no longer able to assist in movement.
This is good news; no argument there. But how does one person's ability to control his mind, and by extension his surroundings, apply to other issues being debated, in some instances, with as little thought as it takes to pick up a sweet?
Among the nonsense being churned out by "keep Terri alive" advocates, there is one argument that gives a thinking person pause. Disabled rights advocates have sighted a slippery slope, whereupon allowing one disabled person to die devalues the lives of every other disabled person. They fear those with physical disabilities will see their own lives as worthless, or that others will, and strides made in assistance to the disabled will halt.
But there's been a misdiagnosis: Instead of a slippery slope argument, it's a classic apples and oranges dispute.
The issue of whether to allow Terri Schiavo to die naturally isn't about physical ability, it's an argument about the mind. In poor Terri's case, it simply doesn't exist. With no brain cortex, or only a few disjointed neurons where it should be, she couldn't possibly make her wishes known to a computer or any other device. Indeed, she's incapable of having wishes, period.
The disabled, on the other hand, have fully functioning minds, or sometimes less severe brain damage that results in cognitive loss, yet not nearly the total loss of cognition that poor Terri has. Even those with a significant amount of brain damage can be self-aware, and have wishes about their own lives and comfort.
Comparing the two situations is disingenuous, and devalues disabled people by assuming a disability is by definition mind-altering. There is no slippery slope here—unless you want to talk about the slippery slope whereby one person's right to refuse medical treatment is ignored, and soon we all will be forced to undergo dramatic medical procedures, such as chemotherapy and CPR, when, with fully functioning minds, we wish not to.
Indeed, all paralyzed people could even be forced to accept the BrainGate implants, for their own good, of course.
Now there's a slippery slope I don't want to head down.
