“The prosperity, and social vitality and technological progress of a people are directly determined by the extent of their liberty. Freedom honors and unleashes human creativity — and creativity determines the strength and wealth of nations. Liberty is both the plan of Heaven for humanity, and the best hope for progress here on Earth.”

Context: A people who have courageously opposed French domination for more than eighty years, a people who have fought side by side with the Allies against the Fascists during these last years, such a people must be free and independent.
For these reasons, we, members of the Provisional Government of the Democratic Republic of Vietnam, solemnly declare to the world that Vietnam has the right to be a free and independent country and in fact it already has been so. The entire Vietnamese people are determined to mobilise all their physical and mental strength, to sacrifice their lives and property in order to safeguard their independence and liberty.

Remarks by President Obama and Prime Minister Abe of Japan at Hiroshima Peace Memorial at Hiroshima Peace Memorial in Hiroshima, Japan (May 27, 2016) https://www.whitehouse.gov/the-press-office/2016/05/27/remarks-president-obama-and-prime-minister-abe-japan-hiroshima-peace

Context: There are many sites around the world that chronicle this war -- memorials that tell stories of courage and heroism; graves and empty camps that echo of unspeakable depravity. Yet in the image of a mushroom cloud that rose into these skies, we are most starkly reminded of humanity’s core contradiction; how the very spark that marks us as a species -- our thoughts, our imagination, our language, our tool-making, our ability to set ourselves apart from nature and bend it to our will -- those very things also give us the capacity for unmatched destruction. [... ] Science allows us to communicate across the seas and fly above the clouds; to cure disease and understand the cosmos. But those same discoveries can be turned into ever-more efficient killing machines. The wars of the modern age teach this truth. Hiroshima teaches this truth. Technological progress without an equivalent progress in human institutions can doom us. The scientific revolution that led to the splitting of an atom requires a moral revolution, as well.

1960s, Farewell address (1961)
Context: Throughout America's adventure in free government, our basic purposes have been to keep the peace, to foster progress in human achievement, and to enhance liberty, dignity and integrity among peoples and among nations. To strive for less would be unworthy of a free and religious people. Any failure traceable to arrogance or our lack of comprehension or readiness to sacrifice would inflict upon us grievous hurt, both at home and abroad.
