I was working with the logic example within the exotica CS book, and it is really impressive logic. Something that I want to use for other types of inferences. There is a lot of possible potential with this little gem.

However, I noticed, when I was testing it, that the test results in the opposite in what I would expect to see as an answer.  Maybe there is a logic change needed, I have not been able to figure it out yet.

(The topic ~compare_test in https://github.com/ChatScript/ChatScript/blob/master/WIKI/ESOTERIC-CHATSCRIPT/ChatScript-Exotica-Examples.md )

Here is a transcript of the test from the code from the md page.

end_user: > Tom is more tall than Mary
HARRY:  Ok, I hear you. Strange comment, but I will take it.
end_user: > Tom is taller than Mary and Tom is shorter than Joan.
HARRY:  If you say so.  How are you, anyway?
end_user: > Tom is less tall than Mary
HARRY:  Ok, Tom is less tall than Mary. You are teaching me concepts. Ok. What are your favorite things to do when you have time off?
end_user: > Tom is taller than Harry but shorter than Joan.
HARRY:  I understand. Did you see my question?

# Here is the test
end_user: > who is taller, Tom or Harry?

# the response is the reverse of what I would expect.
HARRY:  Harry is. Positively

enduser: > :why

# Looks like it is executing the code from the exotica example

end_user: > Of Tom and harry, who is taller?
HARRY:  Harry is.  Positively How can technology improve education? Can it hurt education? 
end_user: > who is less tall, Tom or Harry?
HARRY:  Tom is. Do you usually achieve goals you set? why or why not? 
end_user: > Of Tom and Harry, who is less tall?
HARRY:  Tom is.

I will look at the logic later, but I wanted to point out that it looks like it needs to be reversed.
