Sure,

But I have to warn you that even though I consider the difference to be paramount, the actual difference is truly minor in character.

Let me first use the example that we live in a 2 + 2 makes 4-world, and that nobody has a problem knowing that 4 can be achieved by either adding 2 + 2 or by multiplying 2 X 2. What I am trying to show is the common knowledge that 4 is build up from two 2's and not from four 2's. Everyone agrees on this, but when it comes down to dimensions, everyone all of a sudden wants to follow the path that states that 4 is build up out of four 2's, because they say there is 2 + 2 and there is 2 X 2.

With M-theory I am of the opinion that their practitioners allow themselves to add directions as if all new additions are separate directions. The mini-dimensions are still going in the same directions as the maxi-dimensions, and the main reason M-theory is so fascinating is that once you allow yourself to do something this double, a lot of extra information can come available. I would say, very similar to opening up a second eye (but not ten or eleven eyes).

3D also contains that bit of extra that seemingly is there, but that isn't there (because the extras we experience occur within us and our perceptions, but not in the outside world). 3D are based on singular directions, and they do not exist. Only as a team do the parts of directions exist. Of course, this may come as a surprise; if you have known a certain house down your street to have a brick wall, and you always considered the wall to be made up out of separate bricks plus cement, then it is a big surprise if you walk by the building one day, while they are tearing the building down and the brick wall turned out to be a larger single wall, prefabricated to look like a brick wall. The bricks are merely an inch thick, and the wall is an entire slab. That's a big surprise.

In reality, there are no singular directions, so if we want to use the word dimension and have it be based on itself and not on the whole (which, by the way, is possible, but only if you so desire) then we have to state that a single dimension has at least two directions. A picture, a screen, a piece of paper are all flat and can as such contain information for us to interpret and be considered dimensional (whether rightfully so or not is up to the critics).

In truth, there is only reality, but within this reality we can create something that is fake (art). While we may consider the art to be (one-)dimensional, our reality must then be considered two-dimensional. Yet, if we state that art is nothing but fake and does only contain tricks to the eye, then we live in a one-dimensional world. According to me, that is then the perspective of someone who has one eye shut. I prefer both eyes open and recognize that two eyes deliver something extra: 2D+.
