“Man is man the world over. This fact is affirmed and admitted in any effort to deny it. The sentiments we exhibit, whether love or hate, confidence or fear, respect or contempt, will always imply a like humanity. A smile or a tear has no nationality. Joy and sorrow speak alike in all nations”

This World is all a fleeting Show.
Bartlett's Familiar Quotations, 10th ed. (1919)

1950s, The Russell-Einstein Manifesto (1955)

acting alone, acting in groups, acting in the United Nations, for plague and pestilence, and plunder and pollution, the hazards of nature, and the hunger of children are the foes of every nation. The earth, the sea, and the air are the concern of every nation. And science, technology, and education can be the ally of every nation. Never before has man had such capacity to control his own environment, to end thirst and hunger, to conquer poverty and disease, to banish illiteracy and massive human misery. We have the power to make this the best generation of mankind in the history of the world — or to make it the last.
1963, UN speech

1960, Address at Convention Hall, Philadelphia
Context: In short, I believe in an America that is on the march — an America respected by all nations, friends and foes alike — an America that is moving, doing, working, trying — a strong America in a world of peace. That peace must be based on world law and world order, on the mutual respect of all nations for the rights and powers of others and on a world economy in which no nation lacks the ability to provide a decent standard of living for all of its people. But we cannot have such a world, and we cannot have such a peace, unless the United States has the vitality and the inspiration and the strength. If we continue to stand still, if we continue to lie at anchor, if we continue to sit on dead center, if we content ourselves with the easy life and the rosy assurances, then the gates will soon be open to a lean and hungry enemy.

Earth (1990)

1961, Speech to Special Joint Session of Congress
Context: I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations — explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon — if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.

Sermon III : The Angel's Greeting
Meister Eckhart’s Sermons (1909)
Context: When man humbles himself, God cannot restrain His mercy; He must come down and pour His grace into the humble man, and He gives Himself most of all, and all at once, to the least of all. It is essential to God to give, for His essence is His goodness and His goodness is His love. Love is the root of all joy and sorrow. Slavish fear of God is to be put away. The right fear is the fear of losing God. If the earth flee downward from heaven, it finds heaven beneath it; if it flee upward, it comes again to heaven. The earth cannot flee from heaven: whether it flee up or down, the heaven rains its influence upon it, and stamps its impress upon it, and makes it fruitful, whether it be willing or not. Thus doth God with men: whoever thinketh to escape Him, flies into His bosom, for every corner is open to Him. God brings forth His Son in thee, whether thou likest it or not, whether thou sleepest or wakest; God worketh His own will. That man is unaware of it, is man's fault, for his taste is so spoilt by feeding on earthly things that he cannot relish God's love. If we had love to God, we should relish God, and all His works; we should receive all things from God, and work the same works as He worketh.
