So the idea is that if specific things come together than things happen. And these things that contribute to the outcome, and the outcome itself, are, or can be known. Some kind of scientific or philosophical formula that is supposed to work. Here this idea is being applied to the human mind.
This is the premise of PFAL. And this is why it fails.
The defining of free will, and emphasis, is overstated for one. That you can present ideas, factors, thoughts, scripture, truth, lies or other things and get a specific outcome every time. Oh! but wait! if the outcome does not happen than you must not be believing, or FREE WILLING to believe one or more of these ingredients. Like some kind of cookbook.
God was left out of the class, and taken over by things that we are supposed to do and believe. Somehow the message of not by my own works is lost.
