"FORGET the sentimental notion that foreign policy is a struggle between virtue and vice, with virtue bound to win.

FORGET the utopian notion that a brave new world without power politics will follow the unconditional surrender of wicked nations.

FORGET the crusading notion that any nation, however virtuous and powerful, can have the mission to make the world over in its own image.

REMEMBER that diplomacy without power is feeble, and power without diplomacy is destructive and blind.

REMEMBER that no nation's power is without limits, and hence that its policies must respect the power and interests of others."

In "In Defense of the National Interest: A Critical Examination of American Foreign Policy", Hans J. Morgenthau, 1951.

"Comment s'étaient-ils rencontrés? Par hasard, comme tout le monde. Comment s'appelaient-ils? Que vous importe? D'où venaient-ils? Du lieu le plus prochain. Où allaient-ils? Est-ce que l'on sait où l'on va? Que disaient-ils? Le maître ne disait rien; et Jacques disait que son capitaine disait que tout ce qui nous arrive de bien et de mal ici-bas était écrit là-haut."

Brad: I've done a lot; God knows I've tried
To find the truth. I've even lied.
But all I know is down inside I'm

All: Bleeding...

Janet: And super heroes come to the feast
To taste the flesh not yet deceased.
And all I know is still the beast is

All: Feeding...
Ahh, ahh...

Narrator: And crawling on the planet's face
Some insects, called the human race...
Lost in time, and lost in space,
And meaning.

All: Meaning.

  This is the Way for men who want to learn my strategy:
    1.Do not think dishonestly.
    2.The Way is in training.
    3.Become aquainted with every art.
    4.Know the Ways of all professions.
    5.Distinguish between gain and loss in wordly matters.
    6.Develop intuitive judgement and undestanding.
    7.Perceive those things which cannot be seen.
    8.Pay attention even to trifles.
    9.Do nothing which is of no use.

    Ma paroisse est une paroisse comme les autres. Toutes les paroisses se ressemblent. Les paroisses d'aujourd'hui naturellement. Je le disais hier à M. le Cure de Norenfontes : le bien et le mal doivent s'y faire équilibre, seulement le centre de gravité est placé bas, très bas.
