In looking up the Goebbels quote, I came across several other gems.
This one is also from Goebbels, and it comes to mind whenever I see the baleful stare below the troglodytic brow of Deputy Chief Paul Mascariñas:
“Intellectual activity is a danger to the building of character."
“In politics stupidity is not a handicap.” -- Napoleon Bonaparte
“Those who are too smart to engage in politics are punished by being governed by those who are dumber.” -- Plato
