maybe u really deal with some great problems,but it s clear that u have a lack of information in this case,bcz vision is absolutely nothing without the sinthesizing role of brain,without it u cant perceive any kind of information about the objects,so u cant see them,therefore our sensations will bring no information to us without the recollection by mind ,but in that case u spoke about it is a stupidity to tell that you perceive it with eyes,while thats the most certain generalization of the mind!
