“What lies behind facts like these: that so recently one could not have said Scott was not perfect without earning at least sorrowful disapproval; that a year after the Gang of Four were perfect, they were villains; that in the fifties in the United States a nothing-man called McCarthy was able to intimidate and terrorise sane and sensible people, but that in the sixties young people summoned before similar committees simply laughed.”
—Doris Lessing (b. 1919)
“... the yearly expenses of the existing religious system ... exceed in these United States twenty millions of dollars. Twenty millions! For teaching what? Things unseen and causes unknown!... Twenty millions would more than suffice to make us wise; and alas! do they not more than suffice to make us foolish?”

“Colonel [John Charles] Fremont. Not a good picture, but will do to indicate my politics this year. For free States and against new slave States.”

“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”

“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
