Things are either Right or Wrong
Good or Evil
Positive or Negative
True or False
Fact or Opinion
Correct or Incorrect.
You either have or don't have
You either know or don't know
Moral or Immoral.
There is no relativism as it seems.
No. This is a perceptual error called
Black and White Thinking. It is also called polarized thinking, and can be detrimental to mental health, retarding development of perceptions that can more adequately analyze one's environment and even one's appropriate responses to situations.
It might be good or evil, or neither.
It might be positive or negative, or positive in one situation, but negative in another.
It might be true or false, but no one really knows.
It might be fact or opinion, or maybe description or fiction. But since I can't tell which it is, I should
learn how to distinguish between facts and opinions. And some people state opinions just like they do facts, so boy howdy, can it be confusing.
It might be correct or incorrect, but it's most likely incorrect (sorry, that's a joke--"there is only one correct way, but infinite incorrect ways.") There may be many correct ways, and many incorrect ways.
You either have or don't have sounds like a category error or just an uninteresting statement of fact.
You could know some, but not all. That's still knowing.
You could be moral, immoral, or amoral.
