The quote is from Avatar(Cameron, 2009), by the way. Not one of my favorite movies, but my vote for James Cameron's second best movie after the first Terminator. (Yes, better than Aliens or Titanic. But, for me, that's not saying much.)
I am a professional philosopher with a B.A. in film, an M.A. in theology, and a Ph.D. in philosophy.
