At one point I had the idea that I was going write a bunch of For The Record posts — position papers that attempt to be final words on a topic (at least until new considerations came into play). Other one about guns (back in 2015), I never really followed through.
In a sense, all posts, are final words (until further consideration), so all posts can be seen as FTR. The question is whether it makes any sense to mark an expressed opinion as more official or duly considered rather than off the cuff or casual. That was my thought, anyway.
So, seven years later, FTR take two: Free Will
The notion of emergence — because it is so fundamental — pops up in a lot of physics related discussions. (Emergence itself emerges!) A couple of years ago I posted about it explicitly (see: What Emerges?), but I’ve also invoked it many times in other posts. It’s the very basic idea that combining parts in a certain way creates something not found in the parts themselves. A canonical example is how a color image emerges from red, green, and blue, pixels.
Also often discussed is reductionism, the Yin to the Yang of emergence. One is the opposite of the other. The color image can be reduced to its red, green, and blue, pixels. (The camera in your phone does exactly that.)
Recently I’ve been thinking about the asymmetry of those two, particularly with regard to why (in my opinion) determinism must be false.
The ideas of free will, causality, and determinism, often factor into discussions about religion, morality, society, consciousness, or life in general. The first and last of these ideas seem at odds; if the world is strictly determined, there can be no free will.
But we are confronted with the appearance of free will — choices we make appear to affect the future. Even choosing not to make choices seems to affect our future. If reality is just a ride on fixed rails, then all that choosing must be a trick our brains play.
These questions are central to lives, but answers have remained elusive, in part from differing views of what the key ideas even mean.
Lately I’ve been reading about compatibilism with regard to free will. While I’ve considered free will before, especially in the context of determinism, I’ve never explored compatibilism, and I decided it was time I got around to checking it out.
What triggered my renewed interest was, firstly, the movie Arrival (and the short story on which it’s based), and secondly, the HBO series, Westworld. Both have thoughtful science fiction with themes concerning free will (or its lack).
When one of my favorite physics bloggers, Sabine Hossenfelder, wrote a post about free will, it inspired me to write one, too. Monkey see, monkey do!
I think, I think.
A bit more than three years ago I began this blog intending to write about matters of existence and consciousness (and science and computing). Since then I’ve tried on other hats, stories from my past and present, opinions and views about society, even the occasional post above movies or TV. But those meatier topics — the ones the blog is named for — still attract me.
There are three problems, though. Firstly, other sites specialize in that sort of thing and do it very well. Secondly, they aren’t topics that attract visitors — my meaty posts get even fewer reads than my less weighty posts. And thirdly, I may not be as good as explaining things as I would like to be.
That said, sometimes I just can’t help myself, so here we go again.
