Foolishness
Is there a difference between arrogance and foolish arrogance?
I mean, I think of the confident end of the spectrum, with there being those who are confident (assume rightfully so through competence), those who are arrogant (though competent), and the those who are foolishly arrogant (where their impression of themselves goes beyond their competence). It's these last ones I think of and how their arrogance blinds them to what they aren't seeing. Bumbling along, blindly assuming they're right and everyone else is wrong.
But is there a difference between the last two? Can one be arrogant without being foolishly blind? I dunno, maybe... It's riding a fine line though.
