The purpose of this paper is to make it clear that there is such a thing as levels/degrees of understanding/speaking when we speak of and about reality. If this fact is straightened up and is fixed in our reasoning and thinking, it will make a lot of confusions regarding a wide range of topic just disappear.
It is supposed to be known that this fact is very important and has to be understood so that many fundamental and advance truths may be established in our minds. I realized that this is not so foreign even for not so sophisticated thinkers, but nevertheless, it can escape us. It does escape us, even because it is not yet so fixed in our thinking.
