The world is a dangerous place to live, not because of the people who are evil, but because of the people who don't do anything about it.

You should be the change that you want to see in the world.

An eye for an eye will make the whole world blind.

What really interests me is whether God had any choice in the creation of the world. Remark to Ernst Straus, one of his assistants.

I am not an Athenian or a Greek, but a citizen of the world.

Why change the world when we can change ourselves?

Sometimes I wonder whether the world is being run by smart people who are putting us on, or by imbeciles who really mean it.

The difference between what we do and what we are capable of doing would suffice to solve most of the world's problem.

To be yourself in a world that is constantly trying to make you something else is the greatest accomplishment.

When you want to fool the world, tell the truth.

"Six pints of bitter," said Ford Prefect to the barman of the Horse and Groom. "And quickly please, the world's about to end."

It is curious that physical courage should be so common in the world and moral courage so rare.

The world is nothing, the man is all; in yourself is the law of all nature, and you know not yet how a globule of sap ascends; in yourself slumbers the whole of Reason; it is for you to know all, it is for you to dare all.

Nothing is permanent in this wicked world— not even our troubles.

Today, every inhabitant of this planet must contemplate the day when this planet may no longer be habitable. Every man, woman and child lives under a nuclear sword of Damocles, hanging by the slenderest of threads, capable of being cut at any moment by accident, or miscalculation, or by madness. The weapons of war must be abolished before they abolish us. In an address before the General Assembly of the United Nations on September 25, 1961.

What kind of peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children — not merely peace for Americans but peace for all men and women — not merely peace in our time but peace for all time. Address at The American University, Washington D.C. (10 June 1963)

I believe that the civilisation into which India has evolved is not to be beaten in the world. Nothing can equal the seeds sown by our ancestry. Rome went; Greece shared the same fate; the might of the Pharaohs was broken; Japan has become westernised; of China nothing can be said; but India is still, somehow or other, sound at the foundation.

The Christian resolution to find the world ugly and bad has made the world ugly and bad.

People seem not to see that their opinion of the world is also a confession of character.

It is easy in the world to live after the world's opinion; it is easy in solitude to live after our own; but the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude.

To different minds, the same world is a hell, and a heaven.

In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibility — I welcome it. I do not believe that any of us would exchange places with any other people or any other generation. The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it — and the glow from that fire can truly light the world.
And so, my fellow Americans: ask not what your country can do for you — ask what you can do for your country.
My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man. Inaugural Address (20 January 1961)

If a beachhead of cooperation may push back the jungle of suspicion, let both sides join in creating a new endeavor, not a new balance of power, but a new world of law, where the strong are just and the weak secure and the peace preserved.
All this will not be finished in the first one hundred days. Nor will it be finished in the first one thousand days, nor in the life of this Administration, nor even perhaps in our lifetime on this planet. But let us begin. Inaugural Address (20 January 1961)

The United States, as the world knows, will never start a war. We do not want a war. We do not now expect a war. This generation of Americans has already had enough — more than enough — of war and hate and oppression. We shall be prepared if others wish it. We shall be alert to try to stop it. But we shall also do our part to build a world of peace where the weak are safe and the strong are just. We are not helpless before that task or hopeless of its success. Address at The American University, Washington D.C. (10 June 1963)

The age of antiquity is the youth of the world.
