“Betray, kind husband, Thy spouse to our sights,
And let mine amorous soul court Thy mild Dove,
Who is most true and pleasing to Thee then
When she is embraced and open to most men.”
—John Donne (1572–1631)
“Cassoulet, that best of bean feasts, is everyday fare for a peasant but ambrosia for a gastronome, though its ideal consumer is a 300-pound blocking back who has been splitting firewood nonstop for the last twelve hours on a subzero day in Manitoba.”
—Julia Child (b. 1912)
“We recognize caste in dogs because we rank ourselves by the familiar dog system, a ladderlike social arrangement wherein one individual outranks all others, the next outranks all but the first, and so on down the hierarchy. But the cat system is more like a wheel, with a high-ranking cat at the hub and the others arranged around the rim, all reluctantly acknowledging the superiority of the despot but not necessarily measuring themselves against one another.”
—Elizabeth Marshall Thomas. “Strong and Sensitive Cats,” Atlantic Monthly (July 1994)
