“First, there is no single sustainable model for national success. Second, the American model, which has indeed been successful, is not available to others, because our success depends greatly on our dominant position at the center of the global capitalist system, and we are not willing to yield it.”

Context: The American system demands success, and in order to succeed we must first believe that we can. Yet our society, with its intolerance of failure and poverty, traps millions of people in positions where any kind of success seems impossible to contemplate, and in which failure itself is a kind of passive rebellion against their own misery and the social system which created it in the first place.
To succeed it is necessary to accept the world as it is and rise above it.

Context: We may indeed be justly proud of our apostolic succession. Schools and systems have flourished and gone, schools which have swayed for generations the thought of our guild, and systems that have died before their founders; the philosophies of one age have become the absurdities of the next, and the foolishness of yesterday has become the wisdom of to-morrow; through long ages which were slowly learning what we are hurrying to forget — amid all the changes and chances of twenty-five centuries, the profession has never lacked men who have lived up to these Greek ideals. <!-- p. 628
