Humanity unceasingly strives forward from a lower, more partial and obscure understanding of life to one more general and more lucid.

The sole meaning of life is to serve humanity.

We defend and we build a way of life, not for America alone, but for all mankind.

Life is certainly only worthwhile as it represents struggle for worthy causes. There is no struggle in perfect security. I am quite certain that the human being could not continue to exist if he or she had perfect security.

A life not lived for others is not a life.

It is a poverty to decide that a child must die so that you may live as you wish.
