“The great strength of the totalitarian state is that it forces those who fear it to imitate it.”
The Spirit of Saint Francis de Sales, ch. 7, sct. 3 (1952)
Quoted by Bishop Jean-Pierre Camus in L'esprit de Saint François de Sales, Part 3, ch. 5 http://books.google.com/books?id=XdDvTZWjR_sC&q=%22Ceux-l%C3%A0%22+%22qui+aiment+%C3%A0+se+faire+craindre+craignent+de+se+faire+aimer+et+eux-m%C3%AAmes+craignent+plus+que+tous+les+autres+car+les+autres+ne+craignent+qu'eux+mais+eux+craignent+tous+les+autres%22&pg=PA194#v=onepage (1650)
2009, Nobel Prize acceptance speech (December 2009)
Context: Where force is necessary, we have a moral and strategic interest in binding ourselves to certain rules of conduct. And even as we confront a vicious adversary that abides by no rules, I believe the United States of America must remain a standard bearer in the conduct of war. That is what makes us different from those whom we fight. That is a source of our strength. That is why I prohibited torture. That is why I ordered the prison at Guantanamo Bay closed. And that is why I have reaffirmed America's commitment to abide by the Geneva Conventions. We lose ourselves when we compromise the very ideals that we fight to defend. And we honor — we honor those ideals by upholding them not when it's easy, but when it is hard.
