(English translation below.) Il est un temps où le courage et l'audace tranquilles deviennent pour un peuple, aux moments clés de son existence, la seule forme de prudence convenable. S'il n'accepte pas alors le risque calculé des grandes étapes, il peut manquer sa carrière à tout jamais, exactement comme l'homme qui a peur de sa vie.
My own ad-hoc translation: There comes a time where courage and calm audacity become for a people, at the key moments of its existence, the only kind of acceptable prudence. If it does not then accept the calculated risk of great milestones, it might miss its path forever, just like the man who is afraid of his own life.
I found this quote at the bottom of a statue in a public park in Quebec City. I'm not sure when Lévesque made that quote but I assume this has to do with the Quebec independence movement, in which he was a major figure. Anyway, I thought the quote was quite inspirational.
Here is the statue.
