“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.”
