To me, that sounds more like accident than randomness. If I stumble forward and Monty Hall shouts that that means I choose Door #3, well I had no real prediction in place beforehand of which door it would be. But if Door #3 had a curtain embroidered with small dragons on a sea-blue green ocean, which to me implies Menoly playing a pipe, I might be tempted to choose it regardless of what lies behind Door #3. That isn't random.
I think we need to get the definitions in place
Accident
1. an unfortunate incident that happens unexpectedly and
unintentionally, typically resulting in damage or injury.
"he had an accident at the factory"
2. an event that happens by chance or that is without apparent or deliberate cause.
"the pregnancy was an accident"
Randomness
1. the quality or
state of lacking a pattern or principle of organization; unpredictability.
"we accept randomness in our own lives but we crave logic in art"
If its an accident I would have dropped the box with M&Ms, but I shake it and throw it on the floor, so it is intentionally. But even if I have dropped it by accident, the pattern in which the M&Ms land on the floor are still one that we would refer to as one of randomness, because I can't predict how they land.
Random
1. made, done, or
happening without method or conscious decision.
"apparently random violence"
The idea of me giving you a choice of choosing between (A), (A) or none of them and you not knowing anything about them, is what we refer to as a random choice, because you have to make an arbitrary decision, maybe that is a better word, I don't know.
So I don't completely disagree with you, as I think for the most part, we actually don't have free will. But in cases where we are put to a test or choice, for which we can't draw on any former experiences we have to make a choice based on what I would call free will. And as we grow up, we have to make a lot of these choices and gather experiences and eventually we are left with pretty much no free will as we have so many former experiences that influence our choices. So the only difference between our views are that we as humans through our former experiences decide, how we eventually loose our free will, if that make sense?
Obviously you might have some biological influences based on your genetics etc. But if we will just ignore them for now.
And also you might be right that we have no free will at all
It's not usually the cells of a body that I would point at to find meaning in a choice, but personal history. Personal history is nothing more or less than me. So I'm with you there.
I don't think anyone should think like its your cells deciding. But if you think about it, a human is made up by trillion of cells or how many there are. Yet you don't really have control over your brain, for instance trying to say to yourself that you wont think about anything for the next 5 minutes. And most likely after 15 - 30 seconds you have failed at that, but shouldn't it be possible to do that, if you have complete control? But agree its a weird way to think about it, but none the less interesting, why don't we have better control over our brain and thoughts?
