“the subversion of free speech and free thought are the worst forms of subversion.”

“Restriction of free thought and free speech is the most dangerous of all subversions. It is the one un-American act that could most easily defeat us."[The One Un-American Act, Speech to the Author's Guild Council in New York, on receiving the 1951 Lauterbach Award (December 3, 1952)]”

“Facts are subversive”

“LIFE IS SUBVERSIVE”

“Men fear thought as they fear nothing else on earth -- more than ruin, more even than death. Thought is subversive and revolutionary, destructive and terrible, thought is merciless to privilege, established institutions, and comfortable habits; thought is anarchic and lawless, indifferent to authority, careless of the well-tried wisdom of the ages. Thought looks into the pit of hell and is not afraid ... Thought is great and swift and free, the light of the world, and the chief glory of man.”

“There is a fine line between free speech and hate speech. Free speech encourages debate whereas hate speech incites violence.”
