No one has the power of contrary choice.
I agree. Once you chosen to turn right, you cannot
simultaneously choose to turn left. Once you chosen to move forward, you cannot
simultaneously choose to move back.
The physical world does not allow for contrary choice. I doubt you'll find anyone here that disagrees with that statement.
But we are not talking about making "contrary" choices, we are talking about making choices.
You said that knowledge was
a part of that choice. But knowledge is rarely, if ever 100% certain.
In your example you cited evangelists who abuse the trust of their followers, as if that knowledge should compel all people to choose not to donate money. But choice is never "dictated" so simply. You overlooked the fact that there are evangelists who use donations in good faith and do good works with it. Any rational person weighs
both possibilities and based upon the preponderance of evidence, the existing conditions of their life and their own intuition, decides whether to give their money or not.
This is how our mind works rodger. Do internal and external conditions "influence" our choices? Absolutely. Do they "dictate" them? Absolutely not. People may sometimes act like robots, but contrary to your assumptions it isn't because they aren't capable of considered and rational decisions... they just choose to make the easy ones.
It may give you comfort to feel as if you have no choice in life. It probably makes the bad choices that you've made easier to bear. But for those of us who want to progress spiritually, we have to embrace the fact that our lives are the result of the choices that we've made, and that any progress in our search to improve ourselves is in our hands and requires us to make better ones.
You're driving down the highway with your hands off the wheel hoping that internal and external influences dictate that the car stay on the road. I know that in order to get where I want to go, I have to do the steering.
