Who is man?

This is the fundamental question that must be asked: Who is man? Man is a being who bears within his heart a thirst for the infinite, a thirst for truth -- a truth which is not partial but capable of explaining life's meaning -- since he was created in the image and likeness of God. The grateful recognition that life is an inestimable gift, then, leads to the discovery of one's own profound dignity and the inviolability of every single person. Hence the first step in education is learning to recognize the Creator's image in man, and consequently learning to have a profound respect for every human being and helping others to live a life constant with this supreme dignity.
