But how can I possibly have the ability to contemplate all that you have said without my personal freedom to enact such contemplation?
Nobody is denying your personal freedom to contemplate whatever you want. This really isn't rocket science, why do you keep on posting silly statements like this?
Your scenario effectively removes the "I" from the equation and replaces me with a material entity with no will, no control, no personal interaction - entirely predefined by physically controlled reactions to events.
For the ten millionth time, the "material" and "physical" bit is irrelevant. The "I" is not removed neither is control or personal interaction. The exact opposite of what you say is actually the case, because if what you choose to do is not entirely due to who you have become through your life, and the circumstances of the choice, that
would remove any sort of control from you.
Yet I am free to consciously contradict such a scenario because it is not reality.
In what way does it conflict with reality? You keep on making this utterly baseless claim and can never back it up with anything.
I do exist. I think. I make choices. I interact. I create. I know this does not totally fit in with your perceived logic of cause and effect...
On the contrary, it fits perfectly with cause and effect.
...but it will fit if you acknowledge that you have the ability to consciously invoke a cause which implements an act of conscious will.
Word salad - you being able implement an act of will, is perfectly compatible with it having be caused by all that led up to it.
I do not profess to know how this ability can be explained in purely scientific terms, but it is the amazing reality which enables me to consciously compose this post.
Nothing but cause and effect is needed - you're trying to solve a problem that simply doesn't exist. We don't know exactly how minds work but there is nothing about what they do that suggests that they are not operating as deterministic systems.
There is simply no need for your impossible, self-contradictory magic. And you still haven't addressed the actual reasoning that shows it to be contradictory.
