When the term “free will” is used, often in the past I have focused on the “free” part. I took the significance to be in regard to the recognition that each person has choices to make and that he or she is “free” to make his or her own choices “freely”.
Perhaps there is a second perspective to consider.
Perhaps the “will” is a form of mental energy. This might be known as “willpower”.
Perhaps “willpower” is free energy, and with it the individual is capable of virtually unimaginable accomplishment.
Perhaps the only way to find out is to find out.
