Dear Alan (spokes person, Marsha), There is a condition known as Cortical Blindness. This is presented as the inability to form visual images in the visual cortex. Such a thing can arise from brain injury. This would argue that images ARE formed within the brain. Perhaps you are using "visual images" in a different way. Please be so kind as to explain.
If you, Alan, wish to contribute to MoQ, you also agree to engage in explanations of your statements. Otherwise it is just dogma that a discussion forum has no use for.
