It's not that 'I find it nonsensical', it's that there is no feasible way in which it could exist. The future that you think you haven't made your mind up about yet is already in existence, it's there, those 'decisions' have already been concluded.
You seem quite certain about this.
So you believe that we are not personally accountable for all the thoughts words and actions we invoke in our earthly lifetime.
Let's all change the subject again.
This isn't nearly as watertight a case against Alan's nonsensical view of 'free will' as the purely logical one because it relies on a theory being correct, albeit a
very well tested one that is in day-to-day use in the GPS system. What's more, it doesn't address the infinite regress of "conscious control of our own thought processes" at all. However, since we're here...
The evidence is very strong and doesn't even require general relativity, special relativity will illustrate the point just fine. The key is the
relativity of simultaneity. The example used by Roger Penrose imagines that if two people stroll past each other at (for example) 4 mph (≈1.8 ms⁻ą) relative speed, then the difference between what is happening simultaneously between the two, at the distance of the Andromeda galaxy, is about five and a half days. Hence, if some alien race in Andromeda was deciding whether to invade Earth, they may be convening their meeting to make the choice relative to one of our walkers and yet already have set off to Earth, having made the choice, relative to the other. So much for their 'free will'.
As for being "personally accountable", well I've often been told by religionists that their god
knows what we will choose to do in every situation (omniscience) but somehow that doesn't matter for our accountability. Not entirely sure what the difference is between the future being fixed in the mind of some god and being fixed by actually existing, but such is the religious mind.
Of course things get even more problematic in general relativity and in extreme conditions like black holes the idea of simultaneously pretty much gives up. If you want to know what's happening 'now' inside a black hole, we'd have to ask, "well, how do you want to define 'now'?"
All of which, of course, makes some sort of logically relevant idea of 'the present' even more absurd than it is at first sight.
