Realism

In debates (or even just discussions) people sometimes ask how we know the physical world is really there. A variation asks how we know that what we perceive as the real world is the same as what other people perceive. (One example of this is the inverted spectrum.)

The most accurate answer is: We don’t. Not for sure, anyway. There is at least one assumption built in, but it’s one we have to make to escape our own minds. According to ancient philosophical tradition, the only fact we know for sure is that we ourselves exist. (Although I think there’s an argument to be made about a priori knowledge.)

But, as with the excluded middle, accepting reality as an axiom seems almost necessary if we’re to move forward in any useful way.

Reality IS Virtual (probably)!

virtual realityOne of the things I mentioned in my recent Material Disbelief post was that, if you accept everything physics has discovered in the last 100 years or so — and if you believe in philosophical materialism — you are faced with the very strong possibility that all of reality is some sort of simulation or machine process.

Not only does all the evidence, as well as some basic logic, seem to point in that direction, but as a model of reality it provides easy answers to many of the conundrums of modern physics (e.g. Einstein’s “spooky action at a distance” and some basic questions regarding the Big Bang).

Today I want to lay out the details of the arguments for this.

Material Disbelief

collisionTwo things collided. I saw Leon Wieseltier on The Colbert Report and was enthralled by his view of modern social life. That moved a friend of mine to look for other YouTube videos of Wieseltier. She posted a good one that then moved me to look at more. Bottom line, I ended up watching a fair bit of the man last week. Still enthralled.

Meanwhile, after my last post about religion and atheism, a reader commented that she found the article so balanced she couldn’t tell on which side I stood. As an agnostic, that’s the goal. Yet, in one of the videos, Wieseltier expresses an idea that really grabbed me.

It has to do with on which side of what line I stand.

Determined Thoughts

Rene Descartes

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.
