To be agnostic is to simply not know something. That is how I understand it. I personally prefer to go a step further and say that some things may be impossible to know. Since the only knowledge I have comes from my physical senses of sight and hearing, I have a limitation. I can certainly not hear things that dogs can hear. I also have a limitation on hearing certain sounds that other humans hear. I also happen to be extremely nearsighted. I spent many years unable to see the faces of humans unless they were extremely close. This certainly had an effect on what I think of this world.
My question is, if my senses are limited, then there could be many things that exist beyond my knowledge. They are irrelevant until I can see or hear some evidence. One could accurately call my condition agnosticism, but they could also call it autism. My senses are very different from that of other people. This must be carefully understood so that the things I say are not misunderstood.
I have much trouble with communication. Things that are natural to other people are supernatural to me since they are beyond my understanding. I hope that this clears up the confusion caused by my poor communication skills.
To understand or to misunderstand something implies that a definition of something was even given. This is why I am giving definitions of things in my writing.
