Somebody was asking the other day on Facebook “how can you prove that a table doesn’t exist?”
The answer, ‘walk through the place where that table is supposed to stand’ is so obvious that it hurts.

So, was that table real or not?

You see, a table may exist in two kind of places. In a store/room/backyard and in the imagination/memory of the guys who designed/made/owned it. It can remain ‘in storage’ long after it was forgotten by everybody and/or can be remembered long after it was destroyed.
A tree, on the other hand, can exist – and die, without anybody ever noticing it. Or could have been lovingly planted and taken care of by somebody. Who might die even before the tree ever reaching maturity…

But how can any of us determine whether a table, or a tree, is real or not?

By attempting to walk through it, and hurting ourselves, we only determine that there’s something there. Not at all that we’d hurt ourselves by hitting a tree or a table…

OK, there’s yet another possibility.

Dr. Pierce – who, by the way, was produced by the imagination of a screen-writer, reminds us that neurologically there’s no way of telling apart a dream/nightmare/vision from a ‘legitimate’ perception.

Then it would be possible for whatever each of us perceives on a daily bases to be nothing but some-kind of an elaborate multidimensional movie. Or prank. Played on each of us by some extremely bored ‘arcade operator’. Or by a lab-technician performing some kind of an experiment… In this scenario all other people each of us has ever met would be nothing but characters imagined by the guy who had written the script/devised the experiment…
A slightly different scenario would be that our planet (the whole world?) is a theater, we are the spectators and most of what we perceive is the movie which is played on (for?) us. In this variation we are free to speak amongst us (discuss the movie?) and this would be the explanation for why our perceptions are coordinated so well. After all, all English speakers use the same word for table/tree and most of us are able to differentiate between a table and a chair. Or between a tree and a weed…

Or we could take a completely different road!
There’s a guy, Humberto Maturana, who has reached the conclusion that most humans are not simply aware but also aware of their own awareness. And that this is what really makes us human.
In fact, his ideas make a lot of sense. A dog is aware. If house trained, it will not pee inside and most of them are able to differentiate between their owners and some strangers. But it takes a fully functional human being to step outside of themselves and examine their actions/status.

Without this very self awareness, none of us would be considering ‘reality’. We’d simply walk around the table/tree or directly through the clear space and never waste a second considering whether the table/tree is real.

Or what reality really is.

In this scenario, reality is more like a table than like a tree.
It resembles a tree in the sense that it existed long before any of us ever thought about it and it is like a table in the sense that in order to consider it we need to imagine it first.

Reality exists.
In both scenarios and along both roads. It doesn’t matter whether in the first one we are fed fake sensations and led to believe whatever the screen writer wants us to believe. In order to do that, the screen writer has to exist in the first place. We also have to exist, otherwise there wouldn’t be anyone to watch the movie!
OK, maybe what we perceive has nothing to do (very little?) to the real reality. But that doesn’t mean that a certain reality doesn’t exist at all. Even in the first scenario.

Coming back to the second road, we cannot pretend that OUR reality exists outside us.
Yes, there is a reality – THE reality, which lurks somewhere outside our reach.
What we’re able learn from it, and all we’ll ever be able to learn, is what we’ll be able to imagine first.

Think of it. What do we do when we come across something new?
First we try to classify it among our memories. In fact we try to remember whether we already have a word for it. One imagined by one of our ancestors.
If not, we imagine one ourselves.
And only then we can proclaim that the new thing has been discovered. That it has become ‘real’.
