“If by any chance a playwright wishes to express a political opinion or a moral opinion or a philosophy, he must be a good enough craftsman to do it with so much spice of entertainment in it that the public get the message without being aware of it.”

“I think we ought always to entertain our opinions with some measure of doubt. I shouldn't wish people dogmatically to believe any philosophy, not even mine. ”

“The force of public opinion cannot be resisted when permitted freely to be expressed. The agitation it produces must be submitted to.”

“the general or prevailing opinion in any subject is rarely or never the whole truth; it is only by the collision of adverse opinions that the remainder of the truth has any chance of being supplied”

“I was myself so smitten in public opinion that it was the almost universal view that my political life was at last ended.”

“Deep down, below the surface of the average man's conscience, he hears a voice whispering, "There is something not right," no matter how much his rightness is supported by public opinion or moral code.”
