How we cite our quotes: (Book.Chapter.Paragraph)
Quote #1
Full of desires of soon seeing my dear Mama again, I gave my imagination something of a rest, since the real happiness in store for me relieved me from the necessity of having to seek it in dreams. (4.1.28)
Rousseau is accustomed to turning inward for happiness, as opposed to relying on others to making him happy.
Quote #2
Thanks to you, my happiness is at its height. (6.1.33)
This moment is brought to you by Rousseau's desire to recreate his happiest memories. He wants nothing more than to revisit his memories, over and over again.
Quote #3
I feel more strength and life in me with which to suffer than I had for enjoyment when I was in the flower of my youth and in the midst of genuine happiness. (6.2.3)
Okay, so it's not totally original that Rousseau's happiest years are when he's a youngster. It seems like he's telling us that he matured a little since then.
