“Politics disabuses a person of the notion that you can please everybody. It is an inescapable fact that people will always have different opinions, and some people are going to disagree. Sooner or later, a person constructs his or her own "platform" and stands on it, regardless of what others think, say, or do. It is also true that some people delight in another person's demise.”

Quoted in Leslie Halliwell, Halliwell’s Filmgoers’ Companion ( 1984 http://books.google.com/books?id=SAAqAAAAYAAJ&q=%22Paul+Newman+Acting+is+a+question+of+absorbing+other+people's+personalities+and+adding+some+of+your+own+experience%22&pg=PA3#v=onepage)

Attributed to Pope Francis in a Facebook image circulated circa , this is debunked in "Mass Exodus" at Snopes.com (15 December 2014) http://www.snopes.com/politics/quotes/popeatheist.asp, which asserts there are no credible indications Francis ever made such a statement: "It's not clear where the quote originated, but there is no proof (nor is there precedent) for the claim Pope Francis voiced it."
