Naive realism (or externalism) is probably false

My opponent has missed that because of our constructive perception we are able to transcend the limitations of the frail human body. Though the use of science and technology we have built we are able to change our normal bodies sensory input until we can perceive reality has it is. I will demonstrate this by give a point by point rebuttal to my opponent’s argument. Keep in mind this is all due to constructive perception. Perceptual Variability Their spectrum extends to ultraviolet, a color that humans cannot see. Humans can see in to the ultraviolet with the use of a black light. I think it evident that the perceptions of bees, bats, and humans are all unimaginably different. There’s no way one could even imagine seeing in the visible spectrum of bees or perceiving reality through sonar like bats. A rat’s depth perception is more conceivable, but ultimately something completely different to the way we perceive depth. Assuming I upload this correctly here is how a bee sees a flower. http://www.bio.miami.edu... Here is a link were you can hear on bat jamming another’s sonar. http://motherboard.vice.com... Has for how it would be to use sonar to perceive the world around you ask any sonar operator. Keep in mind that bats can also see. They use sonar in a very similar way to how we do. To help see what our eyes can’t. To my knowledge we have not tried to see how a rat can. Argument from Illusion Color is the most obvious flaw in naive realism. When I look at my desk, I see it as a shade of brown. No doubt, this is because it’s light waves correspond to that sensation. However, we could not say that color is an actual property of the table. It changes color based on lightning and looks different to people with different visible spectrums. Yes it a property of the table. Light is reflected, absorbed, or transmitted when it hits an object and this is based off the properties of the object. It is brown because the table as reflected the brown section of the light waves. Changing the lighting conditions changes what is reflected and what is absorbed. The properties of the table that determine color are not static; if you change any of the conditions you get a different result. A spectrophotometer is able to determine the exact color of an object. http://learn.fi.edu... The same thing goes for texture. It feels smooth but smooth is just a subjective feeling and if we were to look at it through a microscope, it would have many grooves and ridges. The next time you feel it you will use your constructive perception to know it is not smooth. I haven’t tried licking my desk, but I’m sure we could say that my desk has no inherent taste to it. Taste and the other qualities of perception are given to objects by humans, not the other way around. They are not actual qualities of the physical objects. I fully admit I am a bit odd and I have licked desks. Your desk does have a taste to it. Try it you will see for yourself. Yes, taste is an actual quality of an object. Taste is picking up on the chemical makeup of an object. We do this by combining the smell and sensations on our tongue. For example if something tastes salty that object has a high sodium makeup. http://www.scienceofcooking.com... Perception-Independent Properties of Objects/Direct Perception of the World by Means of the Senses I’m sure Pro agrees that experience is mediated, so why does this matter? Because reality is mediated in different ways, as seen as above, thus resulting in subjectivity. The mediation effects the experience. What we bring to bear on experience shapes experience. Yes and that is called constructive perception. The problem that my opponent has is that they forget that experience can teach us reality and to look past our own subjectivity. To be able to stand on the shoulders for the generations before us and use their experience in addition to our own. To use science and technology to force us to see reality as it is. My opponent uses an argument that is out dated. We live in a world that sees reality it is true form more and more each day. We have transcended the limitations of most of our perception. As humans constructive perception is a unique perception, and one my opponent disregards. To my opponent we are only able to perceive what our biology tells us. We alone on the planet can say no the rest of my perception is lying to me this is what is true. That ability is also a type of perception.
