After a very long time of trying to conform to the "will" of others, parents, adults, teachers,--and even that of a god called Jehovah, I have come realize that I have always had free will, but did not perceive it to be so. I felt that things had occured to me in my life which I had no control over, and therefore, my emotional turmoil could be blamed on someone else, or the borg. This was not entirely true.
In my journey to find and love "self", I came to realize that I absolutely can make my own choices....and, so can every other human being. When our perception is distorted by the will of "others", we cannot see that we have this freedom. Sometimes, we want the free will, but we don't want to pay the price. And, sometimes, our choice may not be good for us. Still, it is our free choice.
In our various societies humans have established, we more or less, decide among the moral majority as to what is acceptable behavior. There will always be those who make wrong decisions when excercising their free will, whether it be done in ignorance, or purposely. Murderers exercise their free will to kill. Thieves exercise their free will to steal. If they are caught, they will be held accountable.
As far as our brains being a complex computer, perhaps this is so. If we are programmed by a loving creator(s) that gives us free choice, then what a great system it is. Apparently, scientists have expressed that we have lots of "computer disc space" that remains unused.
I feel that I am essentially free to do anything at all; however, I must also realize the consequences of bad choice, and that I am responsible for my own decisions. We pay the price for our freedoms.
Free will is a gift of complexity. As my JW mom said to me in a note, "you have your own free will to do with your life what you want. I have chosen this faith freely and I am very happy and will never change.I recognised many years ago that this 'truth' is something I had been searching for all my life. It answers everything for me."
I had written to her and told her that I was not upset with her, but that I was upset with an organization that required shunning when it served no loving purpose. This was her reply. I excercized free will when I finally left the JW's, but I paid the price for my decision. I've lost my only living parent. Although I am not happy that we are estranged, it was indeed the best choice for me. The only choice I could make to be true to "self".
