Dictionary defines denial in a few senses, the ones I'm interested in are:
- refusal to believe a doctrine, theory, or the like.
- disbelief in the existence or reality of a thing.
- refusal to recognize or acknowledge.
In particular, I mean unreasonable disbelief in reality of a thing which is definitely, objectively real.
Now, I want to say:
Denial is a horrible [what?]
trait of character? (not really, it's specific, not encompassing whole personality) vice? (same) belief? idea? (no, it's a property of a belief or idea...)
How would you classify it?
