1. nature/nurture

    “‘But you are our equal, if not better,’ the Guermantes seemed, by all their actions, to be saying; and they said it in the nicest way imaginable, so as to be liked and admired, but not so as to be believed; to tease out the fictitious nature of this amiability was to have been what they called well brought up; to believe that amiability to be real was to lack breeding.”

    — Marcel Proust, Sodom and Gomorrah
