Have you ever heard the phrase "perception is reality"? That seems like a logical statement, doesn't it? When you stop and think about it, everything we know of the "reality" we live in is based upon our perceptions. We see, hear, smell, taste, feel (tactile) "things" in the world that provide us with information about our world. I think we give the information garnered from some senses (sight for instance) with more weight than others. However, we usually label items as "real" if they appeal to more than one of our senses at the same time; while we "reserve judgment" on items that may not stimulate as many senses at once.
I guess the most important question is; "What is reality?". When we say reality are we talking about simply the collective observances of the human race as perceived through their sensory organs? Perhaps we mean something more concrete? Perhaps we are discussing an "absolute" reality instead of a "perceptual" reality. I think that we can safely assume that there is a difference between perceptual and absolute reality. The "way of the world" doesn't change simply because one human has differing sensory experiences from another human. Blind people can hear the same note as well as someone who is sighted. Deaf people can see an orange ball as easily as someone who can hear. (Assuming of course, those are the only sensory deprivations they have.)
So, what is the "absolute" reality? What does that mean? I think the jury is still out on those two questions. What I think we mean when we refer to "absolute" reality is, actually, those unbending rules and principles from which sensory mechanisms (such as eyes, auditory nerves, etc...) operate. Obviously, we can affect how we perceive a sensory input by artificial means. However, the underlying principles that govern the creation of the sound, or light wave, or thermal current (etc...) cannot be modified. Those bedrock principles are the ones I'm discussing as being the "absolute" reality. It is easy to manipulate perceptual reality. One merely needs to change or obfuscate the sensory inputs. L.S.D, a popular illicit substance during the late 60's and early 70's was a chemical compound which "confused" the sensory processing system of the mind. You would "hear" colors and "see" sounds. The term used to refer to this is "synesthesia". Within the framework of "absolute" reality your perceptions of that absolute reality don't necessarily dictate how another individual will perceive absolute reality. If you are red/green color blind, for instance, that doesn't make a red light less red and more green for someone who is not red/green color blind. Nor, for that matter, can it change the fact that a red light really is red (in wavelength) and not green (a different wavelength).
The single most compelling argument for perception being reality is that we humans can only interact with absolute reality based upon our "perceptions" of that reality. Ther could be a component of absolute reality speaking to us right now, but if we lacked the sensory organs to hear it we wouldn't respond. Indeed, we wouldn't even know of the existence of such a potential sensory input. I think the arguments that are made for "perception being reality" typically boil down to ; "anything that can't be perceived is irrelevant". Personally, I would say that stance is remarkably astigmatic. What about X-rays, infrared light, and sound waves that are beyond the capacity of the human ear to experience? Do those sources of input no longer become a part of reality if we cannot perceive them? I would say, no. (It is possible to argue that those events are experienced indirectly via their affect on other sensory inputs) However, I think it is important to qualify my statement by saying, our responses to those inputs can only be generated once we perceive them. So the question remains, is perception reality? I think the adequate answer is "almost". More-so from an individual stand-point and less-so from a collective (collectively human) stand-point. We, as humans, by our very exist create a perceptual reality. However, perceptual reality only exists because of absolute reality. Well...at least that is my perceptual reality of the situation!
