The reality we see exists only in our minds

*The Resolution Is Not True* I reject the resolution that the reality we see exists only in our minds. We know that human brains, via eyes, can accurately detect external stimuli in the correct position in space: From the Brain Journal of Neurology, "Visuospatial attention and attention to perceptual attributes...are in accordance with the model of an interactive brain...in which the circuits' [components]...for orientation discrimination are recruited differently according to the position of the stimulus." http://brain.oxfordjournals.org... To translate, the brain can authentically and accurately detect objective stimuli given their real position in space, and this is all accomplished though the brain's interaction with an externally verifiable reality; we're seeing what is objectively there. The study continues, "Horizontal eye movements were monitored with contact electrodes placed on the outer ocular canthi and a reference electrode placed between the eyes." http://brain.oxfordjournals.org... Using this method, the researchers were able to conclude that our eyes and brain can accurately detect the orientation and the position of objective reality. But Pro doesn't seem to see it that way. *Pro's Issues* Pro claims: "We are actually seeing an image which exists only in our mind...the moon appears roughly the size of an orange." My response: Irrespective of perspective distortion, the moon exists outside of the mind, and, though it appears to be "the size of an orange," the image of the moon that we see COULD ONLY EXIST with the objective existence of the moon; we see more than one image of the moon, and it is the collection of those many images that affirms our detection of it. Pro asserts: "The moon does not shrink." My response: That's not true, Pro. "The moon has been shrinking, suggest scientists who spotted relatively young geological features that form when a planetary body cools and contracts." http://news.nationalgeographic.com... Regardless, optical illusions do not negate our detection of reality. If we detect an illusion, that means there is an objective, accurate image, and that we've not arbitrarily detected it; the illusion is even contingent on outside-of-the-mind reality. Pro says: "But we are not debating reality. We are discussing the reality we see and what we see is a very limited version of reality." My response: This sounds like a concession to me. Pro agrees that the reality we see is "of reality," though it may be limited. This seems to negate the resolution that the reality we see exists only in our minds...Pro says we see a version of reality, which, by definition, is not contingent on humans. Pro continues: "There are wavelengths of light which our senses can't detect." My response: Pro, would you agree that we can detect the visible light spectrum? Does the visible light spectrum only exist in our minds? Is the visible light spectrum part of reality? Pro adds: "The picture we see is snapshot...that image exists in one and only one place, our mind." My response: This ignores that the images we see are CONTINGENT on the matter that objectively exists. If an image of something seen in reality exists only in our minds, then why are our minds' images contingent on external stimulus? If images only exist in our mind, why aren't the images matter independent? Why does this "mind only" concept need ANYTHING outside of the mind to occur? Pro responds: "As for your tree falling in a forest, many have made a similar claim. Many claim it makes no sound. I can claim that a rainbow turns into a unicorn when nobody is around to see it. Please provide your proof." My response: While proving that rainbows turn into unicorns may be near-impossible, proving that a falling tree in the forest makes a sound without anyone around is simple. In a forest, there is air and there are animals. The tree falling would vibrate the air molecules, creating a vibration that all those woodland creatures would hear...in fact, I argue that because of the ubiquity of sound-detecting animals and air in a forest, the forest is never silent without anyone around to hear the sounds. Now, I want to see the proof of unicorn metamorphosis from the dispersion of visible light.
