Variant: For in the final analysis, our most basic common link, is that we all inhabit this small planet, we all breathe the same air, we all cherish our children's futures, and we are all mortal.

Context: In short, both the United States and its allies, and the Soviet Union and its allies, have a mutually deep interest in a just and genuine peace and in halting the arms race. Agreements to this end are in the interests of the Soviet Union as well as ours — and even the most hostile nations can be relied upon to accept and keep those treaty obligations, and only those treaty obligations, which are in their own interest. So, let us not be blind to our differences — but let us also direct attention to our common interests and to the means by which those differences can be resolved. And if we cannot end now our differences, at least we can help make the world safe for diversity. For, in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's future. And we are all mortal.
Quotes from book
Profiles in Courage
Profiles in Courage is a 1956 volume of short biographies describing acts of bravery and integrity by eight United States Senators, written by then-Senator John F. Kennedy, who won the Pulitzer Prize for the work. The book profiles senators who defied the opinions of their party and constituents to do what they felt was right and suffered severe criticism and losses in popularity because of their actions. It begins with a quote from Edmund Burke on the courage of the English statesman Charles James Fox, in his 1783 attack upon the tyranny of the East India Company in the House of Commons.The book focuses intensely on mid-19th-century antebellum America and the efforts of senators to delay the American Civil War. Profiles was widely celebrated and became a bestseller. It includes a foreword by Allan Nevins.

Variant: A man does what he must — in spite of personal consequences, in spite of obstacles and dangers and pressures — and that is the basis of all human morality.

Context: The courage of life is often a less dramatic spectacle than the courage of a final moment; but it is no less a magnificent mixture of triumph and tragedy. A man does what he must — in spite of personal consequences, in spite of obstacles and dangers, and pressures — and that is the basis of all human morality. In whatever area in life one may meet the challenges of courage, whatever may be the sacrifices he faces if he follows his conscience — the loss of his friends, his fortune, his contentment, even the esteem of his fellow men — each man must decide for himself the course he will follow. The stories of past courage can define that ingredient — they can teach, they can offer hope, they can provide inspiration. But they cannot supply courage itself. For this each man must look into his own soul.
