Aloha, I am just beginning the course. I've finally felt I have a grasp on true versus false. However, I want to be certain I do. The Yen and Yang concept helped me grasp the polar opposites of true vs false. My question is the yen and yen, and the yang and yang concept also is correct in that "must be true" "cannot be false." "Not necessarily true" "could be false." Further, "could be false" "not necessarily false" lastly, "cannot be true" "must be false." Am I right? Are these correct logical opposites like the Yen and Yang polar opposites?

If we look at truth on a scale of 0 to 100, we can assign not necessarily true and could be true different values.
Must be true=100 (has to be true) Not necessarily true (could be false)=0-99 (includes everything but must be true)
Could be true=1-100 (includes everything except for cannot be true) Cannot be true (must be false)=0 (has to be false)
The key difference between not necessarily true and could be true is that not necessarily true includes cannot be true, whereas could be true includes must be true.
Not necessarily true (could be false) means there's a chance that something's false, but it does not have to be false
Could be true means that there's a chance that something's true, but it doesn't have to be false
The logical opposite of must be true is "not must be true," which means could be false.
The logical opposite of must be false is "not must be false," which means could be true
The logical opposite of could be true is "not could be true," which means cannot be true/must be false
The logical opposite of could be false is "not could be false," which means cannot be false/must be true
