AB,
But if our thoughts are entirely derived from events which are predefined by the laws of physics acting on material elements, our freedom to think would equate to the freedom of a river flowing into the sea with no ability to change direction. I do not recognise your concept of freedom.
Whether or not you recognise something is irrelevant to the reasoning for it.
My persistence aptly demonstrates that I have the consciously driven freedom to choose to be persistent, which renders your answers to be well and truly falsified.
Persistence and obduracy are not the same thing, you cannot just assert an “I” independent of mind, and you can’t falsify an argument by never addressing it.
But unlike my heartbeat, I have conscious control over my breathing which facilitates my freedom to speak my consciously chosen words.
Wrong again. You can’t choose to do what you don't want to do. Even if you only ever drink tea because you don’t like coffee but decide to exercise your “free” will by having coffee instead, that want for coffee will still have preceded the action.
I fully understand the logic put forward to contradict my own conclusions,…
That may or may not be true. So far though your refusal or inability ever to engage with it suggests otherwise.
…and I fully comprehend why this "logic" does not explain the reality of my freedom to ponder and evaluate and criticise such logic.
What you comprehend is an irrational belief that your experience
of “free” will is also the explanation
for it. Your problem though is that that supposed explanation relies on the abandonment of reason and the embracing of magic.
