Our challenges may be new. The instruments with which we meet them may
be new. But those values upon which our success depends − hard work and
honesty, courage and fair play， tolerance and curiosity, loyalty and patriotism
− these things are old. These things are true. They have been the quiet
force of progress throughout our history. What is demanded then is a return
to these truths. What is required of us now is a new era of responsibility
− a recognition， on the part of every American， that we have duties to
ourselves， our nation， and the world， duties that we do not grudgingly
accept but rather seize gladly, firm in the knowledge that there is nothing
so satisfying to the spirit， so defining of our character, than giving
our all to a difficult task.
This is the meaning of our liberty and our creed − why men and women and
children of every race and every faith can join in celebration across this
magnificent mall， and why a man whose father less than sixty years ago
might not have been served at a local restaurant can now stand before you
to take a most sacred oath.
