| >I don't follow your reasoning at all. You seem to be quite confused over how beliefs could possibly work in a predetermined world. Firstly, a lack of free will does not imply predetermination, since it's possible that some things are fundamentally random. Predetermined or random is all the same for the sake of the argument I've made. Both are beyond the control of the subjects. >Secondly, even if everything is predetermined, it can still be the case that our choices can be influenced by our belief in free will. Not really. If "everything is predetermined" then we don't have choices, and what we do (the singular thing that we cannot but do) is only influenced by the start event in the casual chain (that predetermined everything). >Thirdly, whilst we can't "opt" to believe in free will or not, whether or not we believe in it can certainly change over time due to building evidence and argumentation. That only applies to a universe with free will. If free will doesn't exist, then evidence and argumentation doesn't matter -- as those are not the causes that shape our beliefs. Instead both our beliefs and any evidence that appears are determined from the entire predetermined casual chain (or are random, as you said, and as such, are still not based on the presence of evidence or not). |
Free will is incompatible with the concept of choice, because all choices are bound by physical constraints. How do you make a choice without any constraints? The best you can do is random.
Think about any of the choices you made today and think about why you made them. When you take all the inputs into account, most of your outcomes are predictable or random. There's no room for free will when you start looking closely.
