Do we have free will? Modern materialists say, no. This is what I learned watching an episode in a series on science that was hosted by Stephen Hawking on Public Broadcast Television.
Hawking explained the experiments that informed this view. In the experiment, 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 were measured showing that the uptick in brain waves happened before the subject was conscious of the actual decision being made to take the action.
The experiment demonstrated the following sequence: (1) a brain signal occurs about 550 milliseconds prior to the finger’s moving; (2) the subject has an awareness of his decision to move his finger about 200 milliseconds prior to his finger’s moving; (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 the decision. The conclusion is that we are responding to some prior stimuli and only think that we are making independent decisions. Hawking concluded, therefore, that we are determined, as everything is, by natural laws in an endless stream of cause and effect.
But wait, there is more. The scientist who conducted these experiments, Benjamin Libet, actually came to the opposite conclusions. And lest you think this is only an interesting experiment with no practical application, I find some interesting applications to our struggles with sin.
