Famous quotes containing the words functions and/or performed:
“One of the most highly valued functions of used parents these days is to be the villains of their children’s lives, the people the child blames for any shortcomings or disappointments. But if your identity comes from your parents’ failings, then you remain forever a member of the child generation, stuck and unable to move on to an adulthood in which you identify yourself in terms of what you do, not what has been done to you.”
—Frank Pittman (20th century)
“Every ceremony or rite has a value if it is performed without alteration. A ceremony is a book in which a great deal is written. Anyone who understands can read it. One rite often contains more than a hundred books.”
—George Gurdjieff (c. 1877–1949)
