“Long live Chile! Long live the people! Long live the workers!”
Final address (1973)
Context: The people must defend themselves, but they must not sacrifice themselves. The people must not let themselves be destroyed or riddled with bullets, but they cannot be humiliated either.
Workers of my country, I have faith in Chile and its destiny. Other men will overcome this dark and bitter moment when treason seeks to prevail. Keep in mind that, much sooner than later, great avenues will again be opened, through which will pass the free man, to construct a better society.
Long live Chile! Long live the people! Long live the workers!
These are my last words, and I am certain that my sacrifice will not be in vain, I am certain that, at the very least, it will be a moral lesson that will punish felony, cowardice, and treason.

“Long live Montreal, Long live Quebec! Long live Free Quebec!”
Vive Montreal; Vive le Québec! Vive le Québec libre!
From a balcony at Montreal City Hall, with particular emphasis on the word 'libre'. The phrase, a slogan used by Quebecers who favoured Quebec sovereignty, and de Gaulle's use of it, was seen by them as lending his tacit support to the movement. The speech sparked a diplomatic incident with Canada's government, and was condemned by Prime Minister Lester B. Pearson, saying that "Canadians do not need to be liberated."

“The masses once dined on opera and Shakespeare.”
State of the Art (2000)

Was sollen aber die buntschäckigten Balletten in den Opern? Balletten, die auf die Oper nicht die geringste Beziehungen haben. Verderben sie nicht alle mögliche Wirkung, die sie in ihrem Gange gewaltsam unterbrechen?
