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.

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.

Our daily deeds as ordinary South Africans must produce an actual South African reality that will reinforce humanity's belief in justice, strengthen its confidence in the nobility of the human soul, and sustain all our hopes for a glorious life for all.

They alone live, who live for others.
