Many sources mistakenly attribute this quote to Santayana, and one http://books.google.com/books?id=e4tzpkw4caAC&q=%22The+working+of+great+institutions+is+mainly+the+result+of+a+vast+mass+of+routine+petty+malice+self-interest+carelessness+and+sheer+mistake+Only+a+residual+fraction+is+thought%22&pg=PA283#v=onepage even identifies the correct book, without realizing that George Santayana and Giorgio de Santillana are two different people
