Irony.
However how arrogant and unhumble can a man reasonably be judged to be when he says 'take stock of your ignorance, my fellow dopes!'
Like a liberal signaling virtue by crying for the environment, so do I behave like every other dunderheaded mortal, hopefully less harmfully so.
That's what makes me so great, I tell myself with enough half belief to stroke my ego but not so much as to control what anyone else does or thinks.
