[Presumably in response to a student, or?]
Now you have raised a good question about what I have done again, and I have to try to do the first bit of hard work so that you can understand. Maybe you will; maybe you won't; maybe you will understand me in a different way than I understand myself. Maybe you will have your own opinion. That is all OK.
If I am entirely truthful with myself and write it down or talk about it, then at least I have done my part, which is the first step in conversation. In the end, hopefully not before, I and you can evaluate or judge what has gone on in conversation, or discussions, and make any decisions based on that, or not.
This is all a short course in language or learning or knowing or personality or ego psychology, or whatever you want to call it. Here is the shorthand view of the course parts so far.
Description = to tell it like it is as best you can.
Explanation = to tell why you think it is using reason and feeling.
Understanding = to know what it is and why that is so.
Evaluation (or judgment) = to say whether what is and why are good or bad or nothing at all.
And of course there is opinion: your own view and judgment with your own understanding almost always without much description or explanation or discussion.
What have I left out? Oh, conversation (discussion/discourse), and decisions. Discussions are about coming to the same understandings between people. Decisions are about doing something with or about the understanding or opinion you have.
Oh, and do these things always follow in order? Of course they don't. That is the reason for confusion.
Confusion = what the heck (= hell) was that and why.
Now, isn't school fun!
