“A man who is of 'sound mind' is one who keeps his inner madman under lock and key.”

“Putting food under lock and key was one of the great innovations of your culture. No other culture in history has ever put food under lock and key - and putting it there is the cornerstone of your economy.[...] Because if the food wasn't under lock and key, Julie, who would work?”

“This is your heart. Keep it locked until the chap turns up who has the key.”

“A woman should be mindful that the key to one man's heart does not necessarily fits into the lock of another.”

“At first glance, the key and the lock it fits may seem very different," Sazed said. "Different in shape, different in function, different in design. The man who looks at them without knowledge of their true nature might think them opposites, for one is meant to open, and the other to keep closed. Yet, upon closer examination he might see that without one, the other becomes useless. The wise man then sees that both lock and key were created for the same purpose.”

“We feel safer with a madman who talks than with one who cannot open his mouth.”
