神学是心灵的语言,而不是头脑的语言。
可持续发展不是一种选择;它是我们对后代的责任。
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.
The only way to discover the limits of the possible is to go beyond them into the impossible.
