impr(quotes): add French quotes (@Dilem) (#6892)

### Description

Translation of the quote : "I don't think it's that simple. Some people
never observe anything. They simply endure existence with a kind of
passive insistence, and they resist with angry spite anything that might
shake them from their false serenity."
