Blockhead
Heaven and earth fight in vain against a dunce!
Schiller.
A blockhead cannot come in, nor go away, nor sit, nor rise, nor stand, like a man of sense.
La Bruyère.
There never was any party, faction, sect, or cabal whatsoever, in which the most ignorant were not the most violent; for a bee is not a busier animal than a blockhead.
Pope.
