Freedom of choice

What the Rabbi Says About: In an experiment conducted by a man named Benjamin Libet, he asked one of his patients to move his hand whenever he felt like it. Libet discovered that the desire to move his hand appeared in the patient’s brain long before he himself was aware of this desire. In other words, some of our actions may be impulsive, without us even choosing to perform them. In retrospect, it seems like free will to us, but we may only justify the action after it has happened and mistakenly think that it was our desire. It happens so quickly that we are not even aware of the process.
