The real philosopher Rousseau, if memory serves, forced his lover to give up their children to an orphanage (a likely death sentence).
I think Rousseau and Locke are meant to be opposites of the ones whose names they share. The TV show’s Locke is no empiricist at all. And Rousseau is only a loner because of fear, not because of anything good to say about nature. She is insane with grief because her child was taken from her.
That may just prove to be a brilliant insight! I had been confused at the discontinuities between Locke, Rousseau, and their namesake philosophers since the producers had said that characters’ names were significant. Now if they are actually mirror images of their namesakes…brilliant!
