“Give us statehood and your glorious citizenship will be welcome to us and to our children. If you deny us statehood, we decline your citizenship, frankly, proudly, as befits a people who... will preserve their conception of honor, which none can take from them....”

Hermann und Dorothea (1797)

2013, Commencement Address at Ohio State University (May 2013)
Context: Only you can make sure the democracy you inherit is as good as we know it can be. But it requires your dedicated, informed, and engaged citizenship. This citizenship is a harder, higher road to take. But it leads to a better place. It is how we built this country – together. It is the question President Kennedy posed to the nation at his inauguration; the dream that Dr. King invoked. It does not promise easy success or immediate progress. But it has led to success, and it has led to progress. 
That brings me to the second thing I ask of you – I ask you to persevere.

Misattributed
Original: (fr) Quand je suis le plus faible, je vous demande la liberté parce que tel est votre principe ; mais quand je suis le plus fort, je vous l’ôte, parce que tel est le mien

(fr) Also appears in the form "Quand les libéraux sont au pouvoir, nous leur demandons la liberté, parce que c’est leur principe, et, quand nous sommes au pouvoir, nous la leur refusons, parce que c’est le nôtre"

Misattributed to Veuillot in Dune (1965) by Frank Herbert: "When I am weaker than you, I ask you for freedom because that is according to your principles; when I am stronger than you, I take away your freedom because that is according to my principles."

According to Pierre Pierrard, this was attributed to Veuillot by Montalambert, and Veuillot protested he did not say it.

Truman Library address (2006)
Context: I believe we have a responsibility not only to our contemporaries but also to future generations — a responsibility to preserve resources that belong to them as well as to us, and without which none of us can survive. That means we must do much more, and urgently, to prevent or slow down climate change. Everyday that we do nothing, or too little, imposes higher costs on our children and our children’s children. Of course, it reminds me of an African proverb — the earth is not ours but something we hold in trust for future generations. I hope my generation will be worthy of that trust.

"At Large", speech at the Peace Corps twenty-fifth anniversary memorial service (21 September 1986), published in Moyers on Democracy (2008), p. 26
Context: nowiki>[George Washington] in uniform patriotism can salute one flag only, embrace but the first circle of life — one's own land and tribe. In war that is necessary, in peace it is not enough. Events enlarged his embrace to a wholly new idea of nation — the United States of America. But less than a century later his descendant by marriage could not slip the more parochial tether. In the halls of the family home standing on the hill above us, General Robert E. Lee paced back and forth as he weighed the offer of Abraham Lincoln to take command of the Union Army on the eve of the Civil War. Lee turned the offer down and that evening took the train to Richmond. His country was still Virginia. We struggle today with the imperative of a new patriotism and citizenship. The Peace Corps has been showing us the way, and the volunteers and staff whom we honor this morning are the vanguard of that journey.
