“there's a theory that when two people form a relationship, they form a third spiritual entity. When the relationship dies, that entity dies. Grief is a completely natural response, and it's almost impossible to move on if you don't allow yourself to experience it.”

“if you think of a relationship as a living entity, I guess it's one thing if the missing two percent is, like, a fingernail. But when it's the heart, that's a whole different ball of wax.”

“it seems that once again people engage in a search for evidence that is biased toward confirmation. Asked to assess the similarity of two entities, people pay more attention to the ways in which they are similar than to the ways in which they differ. Asked to assess dissimilarity, they become more concerned with differences than with similarities. In other words, when testing a hypothesis of similarity, people look for evidence of similarity rather than dissimilarity, and when testing a hypothesis of dissimilarity, they do the opposite. The relationship one perceives between two entities, then, can vary with the precise form of the question that is asked”

“Marriage was not the combination of two entities into one; it was instead the creation of a third entity whose sole purpose was to sooth and inspire the two individuals.”

“There's the ambiguity of human relationships, for instance. A relationship between two people, just like a sequence of words, is ambiguous if it is open to different interpretations. And if two people do have differing views about their relationship - I don't just mean about its state, I mean about its very nature - then that difference can affect the entire course of their lives.”

“Bodies are real entities. Surfaces and lines are but fictitious entities. A surface without depth, a line without thickness, was never seen by any man; no; nor can any conception be seriously formed of its existence.”
