Do we have free will? Modern science seems to suggest that we do not have free will. This is what I learned watching an episode in a series on science that was hosted by Stephen Hawking on Public Broadcast Television.
In one experiment designed to test question whether humans have free will, the subjects were told to choose to push a button and to note the time on the clock at which the decision was made. At the same time, the subject’s brain waves were being monitored for activity. Over and over again, the brain waves registered activity before the subject was conscious of the decision being made to take the action.
The experiment demonstrated the following sequence: (1) a brain signal occurs about 550 milliseconds prior to the person’s finger moving; (2) the person is aware of his decision to move his finger about 200 milliseconds prior to his finger moving; and (3) the person’s finger moves.
This was interpreted as evidence by Hawking that we don’t have free will. The decisions we make are actually prompted by brain activity before we are conscious of making a decision. The conclusion is that we are responding to some prior stimuli and only think that we are making independent decisions.
This experiment was only one experiment in a series of experiments that demonstrate such things as the cosmological constants that that we learn in physics and the apparent indeterminism that we appear to see in quantum mechanics. Each experiment, however, that to the conclusion that our world and even we are determined by natural laws in an endless stream of cause and effect.
Ancient Greeks might have called it fate. Modern science calls it determinism. We have even have a religious term for this apparent phenomenon: predestination.
I think that skepticism of what we think we know is a good thing. The Apostle Paul seems to agree when he encourages people to “test everything”. Therefore, I dug a little deeper and found that the scientist who first conceived and conducted these experiments, Benjamin Libet, actually came to the opposite conclusion.
Scientific experiments like this often seem hyper-theoretical, but they can have some practical application. As I dug deeper and sought greater understanding of what is going on in these experiments and what it means for you and I, I find some interesting applications to our struggles with sin.
