“Once we are destined to live out our lives in the prison of our mind, our one duty is to furnish it well.”

Remarks by President Obama and Daw Aung San Suu Kyi of Burma in Joint Press Conference at Aung San Suu Kyi Residence in Rangoon, Burma on November 14, 2014 http://www.whitehouse.gov/the-press-office/2014/11/14/remarks-president-obama-and-daw-aung-san-suu-kyi-burma-joint-press-confe
Context: Our struggle for democracy has been carried out with a strong grasp on the principle of nonviolence. And also, we believe in the rule of law. So if you ask how do we propose to resolve all of these problems of violence between communities, between different ethnic groups, we've got to start with rule of law. People have to feel secure before they can start talking to one another. We cannot achieve harmony without security. People who feel threatened are not going to sit down and sort out their problems. So I would like to recommend, as the chair of the Rule of Law and Tranquility Committee -- don't forget that tranquility is also included -- that the government should look to rule of law. It is the duty of the government to make all our people feel secure, and it is the duty of our people to learn to live in harmony with one another.

Nobel acceptance speech (1986)
Context: As long as one dissident is in prison, our freedom will not be true. As long as one child is hungry, our lives will be filled with anguish and shame. What all these victims need above all is to know that they are not alone; that we are not forgetting them, that when their voices are stifled we shall lend them ours, that while their freedom depends on ours, the quality of our freedom depends on theirs.

Section 6 : Higher Life
Founding Address (1876), Life and Destiny (1913)
Context: An ideal is a port toward which we resolve to steer. We may not reach it. The mere fact that our goal is definitely located does not suffice to conduct us thither. But surely we shall thus stand a better chance of making port in the end than if we drift about aimlessly, the sport of winds and tides, without having decided in our own minds in what direction we ought to bend our course.
The moral law is the expression of our inmost nature, and when we live in consonance with it we feel that we are living out our true being.

Part I : Ambiguity and Freedom
The Ethics of Ambiguity (1947)
Variant: Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting
Context: In spite of so many stubborn lies, at every moment, at every opportunity, the truth comes to light, the truth of life and death, of my solitude and my bond with the world, of my freedom and my servitude, of the insignificance and the sovereign importance of each man and all men. There was Stalingrad and there was Buchenwald, and neither of the two wipes out the other. Since we do not succeed in fleeing it, let us therefore try to look the truth in the face. Let us try to assume our fundamental ambiguity. It is in the knowledge of the genuine conditions of our life that we must draw our strength to live and our reason for acting [C'est dans la connaissance des conditions authentiques de notre vie qu'il nous faut puiser la force de vivre et des raisons d'agir].
