Thus, the ultimate choice for a man, inasmuch as he is driven to transcend himself, is to create or to destroy, to love or to hate.

While every human being has a capacity for love, its realization is one of the most difficult achievements.

Care and responsibility are constituent elements of love, but without respect for and knowledge of the beloved person, love deteriorates into domination and possessiveness.

If I am attached to another person because I cannot stand on my own two feet, he or she may be a life saver, but the relationship is not one of love.

The history of man is a graveyard of great cultures that came to catastrophic ends because of their incapacity for planned, rational, voluntary reaction to challenge.

The average American has separated his private life from his existence as a member of his society, and leaves that to the specialists in the government to take care of.

One cannot be deeply responsive to the world without being saddened very often.
