Whatever affects one directly, affects all indirectly. I can never be what I ought to be until you are what you ought to be. This is the interrelated structure of reality.
Martin Luther King, Jr.

One ought never to turn one's back on a threatened danger and try to run away from it. If you do that, you will double the danger. But if you meet it promptly and without flinching, you will reduce the danger by half. Never run away from anything. Never!
Winston Churchill

The probability that we may fail in the struggle ought not to deter us from the support of a cause we believe to be just.
Abraham Lincoln

Everyone ought to bear patiently the results of his own conduct.
William Shakespeare

The trouble with censors is that they worry if a girl has cleavage. They ought to worry if she hasn't any.
Marilyn Monroe

No government ought to be without censors; and where the press is free no one ever will.
Thomas Jefferson

So confident am I in the intentions, as well as wisdom, of the government, that I shall always be satisfied that what is not done, either cannot, or ought not to be done.
Thomas Jefferson

One ought to hold on to one's heart; for if one lets it go, one soon loses control of the head too.
Friedrich Nietzsche

Interdependence is and ought to be as much the ideal of man as self-sufficiency. Man is a social being.
Mahatma Gandhi

One who is injured ought not to return the injury, for on no account can it be right to do an injustice; and it is not right to return an injury, or to do evil to any man, however much we have suffered from him.
Socrates

Every man is a consumer, and ought to be a producer. He is by constitution expensive, and needs to be rich.
Ralph Waldo Emerson

There can be no greater error than to expect, or calculate, upon real favors from nation to nation. It is an illusion which experience must cure, which a just pride ought to discard.
George Washington

Ought we not to ask the media to agree among themselves a voluntary code of conduct, under which they would not say or show anything which could assist the terrorists' morale or their cause while the hijack lasted.
Margaret Thatcher

Even when laws have been written down, they ought not always to remain unaltered.
Aristotle

A wise ruler ought never to keep faith when by doing so it would be against his interests.
Niccolo Machiavelli

Men ought either to be indulged or utterly destroyed, for if you merely offend them they take vengeance, but if you injure them greatly they are unable to retaliate, so that the injury done to a man ought to be such that vengeance cannot be feared.
Niccolo Machiavelli

Severities should be dealt out all at once, so that their suddenness may give less offense; benefits ought to be handed ought drop by drop, so that they may be relished the more.
Niccolo Machiavelli

If you like small government you need to work hard at having a strong national defense that is not so militant. Personal liberty is the purpose of government, to protect liberty - not to run your personal life, not to run the economy, and not to pretend that we can tell the world how they ought to live.
Ron Paul

We ought to fly away from earth to heaven as quickly as we can; and to fly away is to become like God, as far as this is possible; and to become like him is to become holy, just, and wise.
Plato

The rulers of the state are the only persons who ought to have the privilege of lying, either at home or abroad; they may be allowed to lie for the good of the state.
Plato
