Libet's experiments into free will
Thirty years ago, Benjamin Libet produced experimental evidence that seemed to show that we could not possess free will. The experiment is described in the video below. How persuasive do you find it? Could there be any other explanations for his findings?
Here is a brilliant essay on free will by Robert Sapolsky, a professor of Neurobiology. Bear it in mind the next time you praise someone for being attractive or good at sport!
