We become just by performing just actions, temperate by performing temperate actions, brave by performing brave actions.

—Aristotle

Nonviolence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages.

—Thomas Alva Edison

The courage of life is often a less dramatic spectacle than the courage of a final moment, but it is no less than a magnificent mixture of triumph and tragedy. People do what they must — in spite of personal consequences, in spite of obstacles and dangers and pressures — and that is the basis of all human morality.

—John F. Kennedy

Nothing is politically right which is morally wrong.

—Daniel O’Connell

The three hardest tasks in the world are neither physical feats nor intellectual achievements, but moral acts: to return love for hate, to include the excluded, and to say, “I was wrong.”

 —Sydney Harris

What is morally wrong can never be advantageous, even when it enables you to make some gain that you believe to be to your advantage. The mere act of believing that some wrongful course of action constitutes an advantage is pernicious.

—Marcus Tullius Cicero

The moral test of government is how it treats those who are in the dawn of life — the children; those who are in the twilight of life — the aged; and those who are in the shadows of life — the sick, the needy and the handicapped.

—Hubert Humphrey

When I do good, I feel good; when I do bad, I feel bad. That’s my religion.

—Abraham Lincoln

Relativity applies to physics not ethics.

 —Albert Einstein

Integrity is telling myself the truth. And honesty is telling the truth to other people.

 —Spencer Johnson

There is no such thing as a minor lapse in integrity.

 —Tom Peters

Integrity can be neither lost nor concealed not faked nor quenched nor artificially come by nor outlived, nor, I believe, in the long run, denied.

 —Eudora Welty
