Chapters 3 & 4 SynopsisChapters 3 & 4 SynopsisI believe the self-reliance of an external naive realism is the assumption that in that respect is a real world that is external to our mind and senses, and that it exists whether or not we as observers exist, and whether or not we are observing it. This assumption cannot be proved because all of our perceptions, without exception, are mental images, and we have no means to go beyond our mental images. It is one we all comm unless pee-pee without even thinking about it. In the military, we assume the office and the computer in it are there after we leave work at the give the axe of the day and volition be there when we arrive at work in the morning. When we head home at the end of the day, we assume that our house or apartment will be there when we arrive, and that it continued to be there in our absence after we left in the morning. We assume that our friends, relatives, and acquaintances are there whether we can see and talk to t hem or not, and whether or not we are thinking about them. We assume that our parents existed before we were born, and that many of the people we know will be alive after we die. So many of our everyday experiences repeatedly confirm this assumption that most of us hardly question it. It is an assumption that has rattling(a) survival value we know that a speeding car can kill us while we are crossing the street absorbed in our thoughts and unaware, that a stray bullet can instantly obliterate our consciousness without warning, or that we can die from an external agent such as a virus, a bacterium, or a poison. The assumption of external reality is necessary for science to function and to flourish. For the most part, science is the discovering and explaining of the external world. Without this assumption, there would be only the thoughts and images of our own mind (which would be the only existing mind) and there would be no need of science, or anything else. In addition to the assu mption of an external reality, we excessively make the assumption that this reality is objective. This is repeatedly confirmed by our daily experience as well as by scientific observations. I withal learned that objectivity means that observations, experiments, or measurements by one person can be made by another person, who will obtain the equivalent or similar results.
