“I joined this party because I believe in freedom. We are the only party believing that if you give people freedom and responsibility, they will grow stronger and society will grow stronger.”

"Credo" at his official website http://robertfulghum.com/index.php/fulghumweb/credo/; this may be partly influenced by remarks of Albert Einstein in "What Life Means to Einstein: An Interview by George Sylvester Viereck" The Saturday Evening Post (26 October 1929): I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

This contains probably her most famous statement: Freiheit ist immer Freiheit der Andersdenkenden, translated as "Freedom is always the freedom of dissenters."
Variant: Freedom is always and exclusively freedom for the one who thinks differently.
Context: Freedom only for the members of the government, only for the members of the Party — though they are quite numerous — is no freedom at all. Freedom is always the freedom of dissenters. The essence of political freedom depends not on the fanatics of 'justice', but rather on all the invigorating, beneficial, and detergent effects of dissenters. If 'freedom' becomes 'privilege', the workings of political freedom are broken.

Context: I say to you that our goal is freedom, and I believe we are going to get there because however much she strays away from it, the goal of America is freedom. Abused and scorned though we may be as a people, our destiny is tied up in the destiny of America.

Speech http://hansard.millbanksystems.com/commons/1931/dec/03/indian-policy in the House of Commons (3 December 1931).
1931

As quoted in NEA Journal : The Journal of the National Education Association‎ Vol. 41 (1952) p. 300
Context: One of the basic causes for all the trouble in the world today is that people talk too much and think too little. They act too impulsively without thinking. I am not advocating in the slightest that we become mutes with our voices stilled because of fear of criticism of what we might say. That is moral cowardice. And moral cowardice that keeps us from speaking our minds is as dangerous to this country as irresponsible talk. The right way is not always the popular and easy way. Standing for right when it is unpopular is a true test of moral character. The importance of individual thinking to the preservation of our democracy and our freedom cannot be overemphasized. The broader sense of the concept of your role in the defense of democracy is that of the citizen doing his most for the preservation of democracy and peace by independent thinking, making that thinking articulate by translating it into action at the ballot boxes, in the forums, and in everyday life, and being constructive and positive in that thinking and articulation. The most precious thing that democracy gives to us is freedom. You and I cannot escape the fact that the ultimate responsibility for freedom is personal. Our freedoms today are not so much in danger because people are consciously trying to take them away from us as they are in danger because we forget to use them. Freedom unexercised may be freedom forfeited. The preservation of freedom is in the hands of the people themselves — not of the government.
