Who said “When a thing ceases to be a subject of controversy, it ceases to be a subject of interest.”?

“I am continually fascinated at the difficulty intelligent people have in distinguishing what is controversial from what is merely offensive.”

“When a subject is highly controversial — and any question about sex is that — one cannot hope to tell the truth. One can only show how one came to hold whatever opinion one does hold. One can only give one's audience the chance of drawing their own conclusions as they observe the limitations, the prejudices, the idiosyncrasies of the speaker.”

“The dust of controversy is merely the falsehood flying off.”

“All great ideas are controversial, or have been at one time.”

“Every real thought on every real subject knocks the wind out of somebody or other.”

“Good temper is an estate for life.”

“We are not hypocrites in our sleep.”

“Prejudice is the child of ignorance.”

“As is our confidence, so is our capacity.”

“Grace in women has more effect than beauty.”

“The public have neither shame or gratitude.”
