There are two important distinctions I’m not seeing in either the original discussion or the comments. These can be summarized as knowledge about (general knowledge covered in this discussion) and knowledge of (functional knowledge not covered).
First, Functional Knowledge. All of the instances of knowledge and information used are based upon impractical knowledge. That is, you don’t need to know specifics of Pluto because you don’t DO anything with Pluto. You are free ot know something about it which will lead you to enough that you will ever need to know regarding it. However, for specific function, such as how to use a machine, including a weapon, knowing about is not enough. You must have specific, concrete knowledge of the function of the thing itself.
Second, second and third order effects of only knowing about and not knowing specifics of. For History, for example, the tendency lately has become to generalize and even rewrite opinion into history, confusing fact (knowledge of) with opinion. This is very dangerous stuff indeed. For example, the Holocaust. Only knowing about general information about the milieu of the time, and politics lends itself to movable and scalable interpretation. Before long that turns to opinion which is discounted. And before long the weight and reality of the event is gone. It is only when we go to the Holocause museum, see the specific artifacts of what real human beings perpetrated upon other real human beings in a specific date and time in history, that we will remember these things actually happend in time and space, regardless of opinion about them, and that concrete reality, apart from any interpretation of it, is what we must remember and never forget.
