“Leader of the Chorus: Let's see. What shall our city be called? […]
Euelpides: Some name borrowed from the clouds, from these lofty regions in which we dwell — in short, some well-known name.
Pisthetaerus: Do you like Nephelococcygia?”

Context: And the one thing I’ve learned, both in my personal life and in my political life, is that if you want more authority, then you also have to be more responsible. You can’t wear the crown if you can’t bear the cross. […] So my attitude is, if you want to participate then you have to recognize that you have broader responsibilities. […] And that is part of leadership. That’s true, by the way, for you individually as well. You have to be willing to take some risks and do some hard things in order to be a leader. A leader is not just a name, a title, and privileges and perks.

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.

Context: Maybe we didn't pray hard enough. Perhaps we should kneel down like is done in church. Perhaps were using the wrong name. Instead of God, let's say "Our Leader." Let's pray to our leader for candy! Let's pray extra specially hard, and don't open your eyes until I say.

General sources
Context: O Star (the fairest one in sight)
We grant your loftiness the right
To some obscurity of cloud —
It will not do to say of night,
Since dark is what brings out your light.
Some mystery becomes the proud.
But to be wholly taciturn
In your reserve is not allowed.
Say something to us that we can learn
By heart and when alone repeat.
Say something! And it says "I burn."
