“This young century will be liberty's century. By promoting liberty abroad, we will build a safer world. By encouraging liberty at home, we will build a more hopeful America. Like generations before us, we have a calling from beyond the stars to stand for freedom. This is the everlasting dream of America.”

Day of Affirmation Address (1966)
Context: This is a Day of Affirmation, a celebration of liberty. We stand here in the name of freedom.
At the heart of that Western freedom and democracy is the belief that the individual man, the child of God, is the touchstone of value, and all society, groups, the state, exist for his benefit. Therefore the enlargement of liberty for individual human beings must be the supreme goal and the abiding practice of any Western society.
The first element of this individual liberty is the freedom of speech: the right to express and communicate ideas, to set oneself apart from the dumb beasts of field and forest; to recall governments to their duties and obligations; above all, the right to affirm one's membership and allegiance to the body politic — to society — to the men with whom we share our land, our heritage, and our children's future.
