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.

For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!

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.

I will use the rest of my life to help the poor overcome the problems confronting them - poverty is the greatest challenge facing humanity. That is why I build schools; I want to free people from poverty and illiteracy.

I conjure you, my brethren, to remain faithful to earth, and do not believe those who speak unto you of super terrestrial hopes! Poisoners they are, whether they know it or not.
