“We are Communist, you are Capitalist. You have your ideas, we have ours. But I tell you this much: many American generals are very often sorry that they have no ideal to plant in the heart of the American soldier, so he will be willing to die for that ideal. You are jealous of us for this. The Communist soldier, the Red Army soldier, has such an ideal in his heart. He has it because he considers the ideal of the commander his own ideal. Your generals in Korea were sorry that Americans were not fighting willingly. We couldn't tell them why this was so, but I will tell you why. There is a difference between us. We have an advantage over you. We have an ideal for which we are prepared to die. You have not.”

2009, First Inaugural Address (January 2009)
Context: Forty-four Americans have now taken the presidential oath. The words have been spoken during rising tides of prosperity and the still waters of peace. Yet, every so often the oath is taken amidst gathering clouds and raging storms. At these moments, America has carried on not simply because of the skill or vision of those in high office, but because We the People have remained faithful to the ideals of our forbearers, and true to our founding documents. So it has been. So it must be with this generation of Americans.

As A Man Thinketh (1902), Visions and Ideals
Context: In all human affairs there are efforts, and there are results, and the strength of the effort is the measure of the result. Chance is not. Gifts, powers, material, intellectual, and spiritual possessions are the fruits of effort; they are thoughts completed, objects accomplished, visions realized.
The Vision that you glorify in your mind, the Ideal that you enthrone in your heart — this you will build your life by, this you will become.

Statement after the suicide of Aaron Swartz, in "An Incredible Soul": Larry Lessig Remembers Aaron Swartz After Cyberactivist’s Suicide Before Trial; Parents Blame Prosecutor" at Democracy NOW! (14 January 2013) http://www.democracynow.org/2013/1/14/an_incredible_soul_lawrence_lessig_remembers
Context: I received an email from JSTOR four days before Aaron died, from the president of JSTOR, announcing, celebrating that JSTOR was going to release all of these journal articles to anybody around the world who wanted access — exactly what Aaron was fighting for. And I didn’t have time to send it to Aaron; I was on — I was traveling. But I looked forward to seeing him again — I had just seen him the week before — and celebrating that this is what had happened. So, all of us think there are a thousand things we could have done, a thousand things we could have done, and we have to do, because Aaron Swartz is now an icon, an ideal. He is what we will be fighting for, all of us, for the rest of our lives. … Every time you saw Aaron, he was surrounded by five or 10 different people who loved and respected and worked with him. He was depressed because he was increasingly recognizing that the idealism he brought to this fight maybe wasn’t enough. When he saw all of his wealth gone, and he recognized his parents were going to have to mortgage their house so he could afford a lawyer to fight a government that treated him as if he were a 9/11 terrorist, as if what he was doing was threatening the infrastructure of the United States, when he saw that and he recognized how — how incredibly difficult that fight was going to be, of course he was depressed.
Now, you know, I’m not a psychiatrist. I don’t know whether there was something wrong with him because of — you know, beyond the rational reason he had to be depressed, but I don’t — I don’t — I don’t have patience for people who want to say, "Oh, this was just a crazy person; this was just a person with a psychological problem who killed himself." No. This was somebody — this was somebody who was pushed to the edge by what I think of as a kind of bullying by our government. A bullying by our government.
