Some excerpts from the article describing this amazing feat (HT: The Pearcey Report):

A man paralysed from the neck down has shown he can open email, control a TV and move objects with a robotic arm by thought alone.

The 25-year-old American patient, Matthew Nagle, had a computer-linked implant placed in his brain that enabled him to operate devices just by thinking about it....by imagining a particular task being carried out....

Known as the BrainGate Neural Interface System, it consists of an array of electrodes that record neural activity from the motor cortex of the brain.

Signals from the implant are decoded and processed by a computer, allowing them to be translated into movement commands.

First, Mr. Nagle learned to move a computer cursor by focusing his thoughts on the task....

He was able to open simulated e-mail, draw circular shapes on the computer screen, play a simple video game called "neural Pong", and change the channel and adjust the volume on a television.

Ultimately, he could open and close the fingers of an artificial hand and use a robotic arm to grasp and move objects.

Initiated by his will to move (the initiation is not in itself a physical process, nor is it determined by a physical process, but the action is initiated by the will of the man), Nagle's thoughts are then translated into something physical (the electrical impulses in his brain) which are then translated by man-made equipment into information used to move physical objects in the world.

The real mystery, known to God alone, is how the desires of our minds are translated into the physical impulses of our brains--how something non-physical interacts with the physical.  Scientists can only build machines that measure the physical impulses, but they could never have access to the thoughts themselves.  The truth is, the will to move parts of our body is not determined by physical impulses, it causes them. 

The title of this post may have surprised you, but it shouldn't.  You move a physical object every day with your mind--your own body!

Is it any surprise, then, that the God who created a way for your mind to interact with the physical machine of your body can Himself affect the physical world, though He is non-physical?

Can we have any true knowledge in a world where we developed by chance?

The concept of creation or design is the crucial assumption that believers of the nineteenth century overlooked when they thought the sciences could proceed without any distinctively Christian presuppositions.  Apart from the doctrine of creation or design, there is no basis for trusting that the ideas in my mind have any correlation to the world outside.  If the human mind is a product of chance events, preserved by natural selection, then there is no basis for trusting any of our ideas.  Recall Darwin's "horrid doubt" that the human mind could be trusted at all, if it is a product of evolution.  The non-Christian pursuing his research has no choice but to rely on his senses, just as everyone else does; but he has no philosophical basis for doing so.  He is being inconsistent with his own worldview.  (Nancy Pearcey, Total Truth, p. 315)

Though scientists may have a hard time accepting this (since their work and authority depend on their being able to perceive reality), many others who recognize the implications of Darwinism (and don't have their livelihood threatened by the outcome) have already proceeded willingly down this path from naturalistic Darwinism, accepting the postmodern view that we do not have access to reality.  Therefore, the most important consideration for these people when choosing their beliefs is not truth itself (since "truth" is in the eye of the beholder), but rather, they are concerned primarily with how the beliefs in question may affect others--insult, empower, alienate, etc. 

Many Christians also accept this perspective (or a form of this that goes beyond an appropriate acknowledgment of human fallibility), not realizing that the view is a direct result of naturalistic thinking.  But our grounds, as Christians, for believing that we have the ability to perceive reality and can have reasonably confident ideas about the truth (even if that confidence can never be absolute) are these:  Our senses did not develop by random chance such that we can never know if they perceive reality; God designed us to interact successfully with the world.  Pearcey describes this using a phrase from Udo Middelmann:  "Because God created us in His image, to function in His world, there is a 'continuity of categories' between God's mind, our minds, and the structure of the world."

This kind of confidence in the possibility of knowledge can only be grounded in a theistic framework.
