“Paradoxically, the ability to be alone is the condition for the ability to love.”

“Today I, tomorrow you. But this need of help does not mean that the one is helpless, the other powerful. Helplesness is a transitory condition; the ability to stand and walk on one's own feet is the permanent and common one”

“To have faith requires courage, the ability to take a risk, the readiness even to accept pain and disappointment. Whoever insists on safety and security as primary conditions of life cannot have faith; whoever shuts himself off in a system of defense, where distance and possession are his means of security, makes himself a prisoner. To be loved, and to love, need courage, the courage to judge certain values as of ultimate concern—and to take the jump and to stake everything on these values.”

“To spare oneself from grief at all cost can be achieved only at the price of total detachment, which excludes the ability to experience happiness.”

“In love the paradox occurs that two beings become one and yet remain two.”

“We forget that, although freedom of speech constitutes an important victory in the battle against old restraints, modern man is in a position where much of what "he" thinks and says are the things that everybody else thinks and says; that he has not acquired the ability to think originally - that is, for himself - which alone gives meaning to his claim that nobody can interfere with the expression of his thoughts.”

“Freedom to creat and construct, to wonder and to venture. Such freedom requires that the individual be active and responsible, not a slave or a well-fed cog in the machine . . . It is not enough that men are not slaves; if social conditions further the existence of automatons, the result will not be love of life, but love of death.”
