Could one argue that thoughts are just as existent but the means of communication are just messed up.
I think this goes beyond what i am saying but there is also reason for this.
I agree with pookie's arguement of dimensions of vision. I believe dreams are the closest to proving vision without eyes. This raises the question, is this an act of a non-physical presence (soul) or something that relies on the existence of physical life.
Well based on evolution could one assume that the existence of a non-physical being is a means of allowing the body to cope with its high level of thought process?
There could have been the existence of an entirely physical body trapped by the mere level of thought capability that it was not able to physically overcome thought to complete tasks to survive.
So then you open up... is it possible to feel nothing as well.
I think your statements further clarify (to me) my thoughts. Is it possible to be consciously aware of not seeing or "seeing" nothing when infact you are not able to see.
