Your post is "the assumption of an external reality is the assumption that there 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 commonly make without even thinking about it. We assume the office and the computer in it are there after we leave work at the end of the day and will 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 them 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 enormous 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, bacterium, or poison.Well my post answered the opening post exactly as far as I can tell, I explained the imagined beginning point of a thought or image envisioned within the mind of the interpreter of logic, and the causality of all sense attachment,, also I explained the cause and effect to "vision only", he cannot find the way to eliminate the innate tension he experiences by his belief that he, the subject, is separate from that, the object of his vision., and I also covered The wisdom that takes man beyond his human intellectual interpretation of dualism of Self, be it Self interpretation of vision-causality-logic or be it Self interpretation of passion-attachment-emotionalism, and into the wisdom of being moved by his conscience-of-Self and his conscience-of-Self alone?
So my post appeared to me to be the most important post in the thread, being as I am the only person that can explain the pre-thought which is dualism.
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 assumption of an external reality, we also make the assumption that this reality is objective. Objectivity means that observations, experiments, or measurements by one person can be made by another person, who will obtain the same or similar results. The second person will be able to confirm that the results are the same or similar by consultation with the first person. Hence, communication is essential to objectivity. In fact, an observation that is not communicated and agreed upon is not generally accepted as a valid observation of objective reality. Because agreement is required, objective reality is sometimes called consensus reality.
Questions: Is there any proof that anything exists if you are not observing it?
If you cite the reports of others, is there any proof that they exist if you are not observing them?
If you cite indirect evidence, is there any proof that that exists if you are not observing it?"
