why do people think the human perception fools us?? please critique my analogy?

Question

for example, people say that you cant actualy 100% prove the existence of others because it may just be one big dream. however our senses do not fool us. in dreams we cannot feel any of our senses acept for images. we know this because when you want to know if your dreaming then you pinch yourself, and if you feel pain then you arent dreaming. i do however beleive that we can never truly know a color of something because of the photons and the way the human perceives color. a humans blue may be another animals green. but other than that we can know that there are objects existing independently from us because that where our senses come from. we cant have a dream in which we have senses unless you have had prioe reference and experience to them.

Answer 1

I played Golden Tee Golf in a bar with some acquaintances and a new guy I did know for about an hour one night. After a while, the new guy takes off his sunglasses, and looks at me. I couldn't believe it. It was the bar owner. He had shaved off his Santa Claus beard, dyed his hair from silver to brown, changed his jeans for slacks, his Harley Davidson shirt for a Hawaiian shirt, changed his shoes, watch, wallet, voice inflection and accent...I had know idea I was playing with him.

Perceptions can fool us when we aren't looking.

Answer 2

You cannot perform ANY test that will determine what is a dream, because you could just be dreaming while you perform the test.

Having an experience of even the MOST certain percpetions "This is my hand," is perfectly consistent with your perceiving a fleshy-looking object that looks identical to your hand.

An empirical theory doesn't decide by virtue of its plausability the absolute veridicality of perception and the necessity of objects beyond sensation. If anything, we're only presented with sensations and can never rationally infer the continued existence of the world BECAUSE of empiricsm.

Answer 3

All sensory impressions are contrived to make us see the world in a particular way. In many way it is just a dream.

This is more easily understandable if one considers the actual scale of the components of an atom. If one takes into account the fact that the neutrons, protons and electrons of an atom actually have huge spaces between them it becomes clear that the atoms that make up seemingly solid objects are made up of 99+ percent empty space.

This alone does not seem too important till you add the idea that the atoms that make up seemingly solid objects are more of a loose conglomeration that share a similar attraction but never really touch each other.

At first glance this does not really seem relevant, but closer analysis reveals that this adds a tremendous amount of empty space to solid objects that are already made up of atoms that are 99 percent space. When so-called solid objects are seen in this light it becomes apparent that they can in no way be the seemingly solid objects they appear to be.

We ourselves are not exceptions to this phenomenon.

These seemingly solid objects are more like ghostly images that we interpret as solid objects based on our perceptual conclusions.

From this we must conclude that Perception is some sort of a trick that helps us to take these ghostly images and turn them into a world we can associate and interact with. This clever device seems to be a creation of our intellect that enables us to interact with each other in what appears to be a three dimensional reality.

I hope that helps to answered your question.
