WHAT YOU SEE
IS MUCH DIFFERENT THAN
THE THINGS YOU ARE LOOKING AT.
What you see is the light that is reflected off of the things that you are looking at.
Reflected light is not what the things that you are looking at actually are.
Then, the reflected light that enters your eyes is focused by a lens onto the retinas of your eyes where it is changed into electrical impulses.
Those electrical impulses are different from the reflected light that entered your eyes which was also different from the things that you are looking at.
Then, those electrical impulses that were created from the reflected light are transmitted over the cells of your optic nerve as signals to your brain.
Those signals received by your brain are different from the electrical impulses that were created by the reflected light that entered your eyes, which were also different from what the things that you are looking at actually are.
So, the things that you “see” are just reflected light, that has been changed into electrical impulses, which are transmitted over nerve cells, that are then received as signals by your brain.
Then, after all of those changes occur, the signals received by your brain become “pictures” (or moving “pictures”) that you think that you “see” of the things that you are looking at.
But nobody knows how that change from signals to “pictures” takes place; and nobody knows what the “pictures” that you think that you “see” actually are; because no one knows what “consciousness” is.
However, whatever “consciousness” may or may not be, it is much different than what the things that you are looking at actually are.
That is why what you think that you “see” is much different than the things that you are looking at.
And, incidentally, you also do not actually “see” a thing when you use some electronic instruments to observe it. Because all that the instrument shows is the effect that the thing in some way or other has on the instrument; and that effect is not the thing that you are attempting to observe.
