Look at it like this: You are the viewpoint. What you are looking at is the dimension ( space )
In other words, space is being defined as: that which you are looking at. Granted it's a nebulous definition, but isn't space rather nebulous anyway? No one can say where its borders are. So it might as well be defined as that which you can see. Even the vaunted Hubble can't see the edge of space - it's too far away.
Thanks for trying to explain, but I don't buy it. Space is not "that which you are looking at" as you say above.
If the viewpoint is the spirit, or the location of the spirit, and anchor points or mocked up MEST is what he is viewing, then the space is what is in between. No need to make it complex.
It's a simple concept, but Hubs was making it twisted in order to sound profound.
