I am aware that when we see something, we are getting only a measure of information, a sense, an inkling of what is really there to see. I don't know the details or the terminology but I do know that the optic nerve is not telling the full truth. We're seeing only intimations. The rest is our invention, our way of constructing what is actual, if there is any such thing, philosophically, that we can call actual.
