Graham Greene

"A man in love walks through the world like an anarchist, carrying a time bomb" 

The Human Factor (1978)

"We make a cage for air with holes, I thought, and man makes a cage for his religion in much the same way--with doubts left open to the weather and creeds opening on innumerable interpretations"

"Suffering is not increased by numbers; one body can contain all the suffering the world can feel"

"Perhaps to the soldier the civilian is the man who employs him to kill, who includes the guilt of murder in the pay-envelope and escapes responsibility" 

The Quiet American (1955)
