Well said, Geoff
One needs to get past freshman and sophomore philosophy to see what the Buddha discovered - and the forest of views, the thicket of views, that don't lead to the end of suffering. IMHO, it doesn't matter if there is ultimately "free will, freedom of choice" or not. Neither is a "thing" of inherent existence. At best they are concepts, fabricated and composite.
IMHO, it's a matter of asking the wrong question and applying the wrong criteria. Does one ask what is the origin of Cherry Tarts? What is the truth of Cherry Tarts? I think all of us can see that Cherry Tarts have essentially nothing to do with what the Buddha taught.
To this, I can picture the Buddha saying, "Look at the recipe. Try it, see if it works, keep it if it does, discard it if it doesn't." (Poorly paraphrased from the advice to the Kalamas)
I can't picture him saying, "There is only one recipe for Cherry Tart. There is only this, all else is wrong." (Canki Sutta for reference) IMO, the question is not "What is the only right way?" It is more like, "how does it work for you" because there is more than one way to go at it." IMHO, this implies that I have choice.
In my brief exposure, Buddhism is "learn and do" more than learn and debate. It's useful to swap ideas and look at the interpretations but for me, at least, it then comes down to "what difference does this make to my practice or my snail's pace toward liberation."
Can I ever truly know the ultimate answers, or will I end up taking refuge in the words of others or just my own preferences/views? "Did I really just solve what hasn't been resolved in 2,500 to 4,000 years of philosophical debate?" It can be a humbling reality check when I'm engaged in debate. On my beter days I choose not to pick it up. On other days I set it back down as not conducive to the goal.
I'm not good at this, mind you. I only share this thought because it has helped me on the path. May it be of benefit to others, too.
