Perceptual Relativity Quotes

“Some animals can see only in black and white, so everything is a shade of grey, others can see in various colors. If you cease to look at something and it continues to exist, what color does it have? The color one species sees it in, or the color another species sees it in? Clearly it can't be grey and have another color at the same time. The same applies to other sense perceptions, a vibration in the air sounds different to different species, the same odour can smell different to different species. Remove the observer, what sound or smell continues to exist. The way one observer hears the sound or the way the other observer hears it? Does an odour continue to exist the way one observer smells it or the way another smells it? Something cannot be of different colors, smells or sounds at the same time. Clearly the sense perceptions a particular observer has disappear when the observer ceases to be making an observation.”

“One of the most neglected areas in the philosophy of perception concerns animal senses. It is surprising how many philosophers write about perception in the apparent belief that humans are the only perceivers in the world. Human senses evolved through the natural process as other animal senses, so there is no reason to regard human senses as special, or better than other animal senses.”

“A significant part of the history of science has been the dethroning of human beings from being the centre of existence. Copernicus and Kepler showed the Earth was not the centre of the universe with everything orbiting the Earth. Darwin showed that the human being is just another animal, which has evolved like all other animals and shares ancestors with all other living species. It is time to dethrone the human view of the world and recognize that it is just another view of the world, no more real or true than the view of any other species.”

“Our senses have evolved over millions of years in order to help us to survive. They give us information as to whether food is safe to eat, where potential prey may be and whether potential predators are around. They are designed to give us information relevant to our survival. Information not relevant to our survival, will not normally be available to us. Our senses are not designed to give us an accurate objective view of the world. They require a certain amount of energy to operate and human survival requires that energy is not wasted in providing us with information not relevant to our continued survival as a species. It is hardly surprising our senses do not give an accurate or objective view of the world. They are simply not intended for that purpose.”

“All our scientific instruments and our scientific experiments are just different ways of seeing the world. The world we perceive through our unaided sensory apparatus is just one view of the universe. Change the sensory apparatus and you change the world you live in. At present we have no way of knowing how the world really is, if it has some real form at all. All our knowledge of the world comes through our sensory apparatus and our scientific instruments and experiments and they give us views of the world conditioned and controlled by the nature of our sensory apparatus, scientific instruments and experiments. If anyone was able to get to a real world not controlled or conditioned by sensory apparatus, instruments and experiments, it may be the greatest intellectual achievement in human history.”

“Each species has its own sensory world, which are often very different from each other species sensory world. There is some overlap between these worlds but there are many aspects of one species world which will be completely unknown to members of other species. The human view of the world is only one view and is no more valid than that of any other species.”
