Sensory Worlds 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.”

“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.”
