“Our country! In her intercourse with foreign nations, may she always be in the right; but our country, right or wrong.”
—Stephen Decatur (1779–1820)
“The term preschooler signals another change in our expectations of children. While toddler refers to physical development, preschooler refers to a social and intellectual activity: going to school. That shift in emphasis is tremendously important, for it is at this age that we think of children as social creatures who can begin to solve problems.”
—Lawrence Kutner (20th century)
“Preach in the name of God. The learned will smile; ask the learned what they have done for their country. The priests will excommunicate you; say to the priests that you know God better than all of them together do, and that between God and His law you have no need of any intermediary. The people will understand you, and repeat with you: We believe in God the Father, who is Intelligence and Love, Creator and Teacher of Humanity. And in this saying you and the People will conquer.”
—Giuseppe Mazzini (1805–1872)
