I believe that we can. I believe the problems of human destiny are not beyond the reach of human beings.

Liberty without learning is always in peril; learning without liberty is always in vain.

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.
