Famous quotes containing the word pitch:
“People do not know the natural infirmity of their mind: it does nothing but ferret and quest, and keeps incessantly whirling around, building up and becoming entangled in its own work, like our silkworms, and is suffocated in it: a mouse in a pitch barrel.”
—Michel de Montaigne (1533–1592)
