Goetz: Because Good has already been done.
Catherine: Who has done it?
Goetz: God the Father. I, on the other hand, am improvising.”

Context: Suddenly, however, remedies for something called 'racism' became the order of the day. The word itself, like 'sexism', is of recent coinage and will not be found in any older dictionaries. The civil rights movement, premised upon individual rights, suddenly became the black power movement, premised upon group rights. 'Affirmative action' became a euphemism for the baldest kind of racial discrimination. That whites had long enjoyed preference over blacks was now taken to be a justification for blacks having preference over whites. What was lost sight of was that the evil of the past, whether of slavery or of Jim Crow, was evil not because it was done by whites to blacks, but because it was done by some human beings to other human beings. The purpose of the law was to end evil acts, not continue them in the guise of 'affirmative action'.
