The quote from "Shadow of the Giant" by Orson Scott Card highlights a deep human desire for possession and belonging. It suggests that people have an inherent need to claim what they see and love, leading to a possessive attitude towards relationships and resources. The idea is that love and ownership are intertwined; individuals may share their possessions, but only if they perceive others as extensions of themselves. This possessiveness can create a sense of entitlement, where one feels they have the right to demand what others possess.
