Science ... is organized common sense.

Faith in the continuance and enhancement of the intrinsic values--faith in truth, in beauty, in friendship, in love and harmony of life--in short, faith in reason and the worth of spiritual life--such faith is only another name for faith in the persistence of spiritual individuality. For, I repeat, these values are real only as functions of personal experience and deed. To have faith in the permanence of intrinsic values is to assume the enduring reality of selves who know truth, feel beauty, who love and win spiritual harmony.

This is the very heart of true morality--not to struggle, not to fight with any weapons, for one's self alone--but to struggle and to fight for the common interest, to wield the power of brain and good right arm if need be for one's family, for the ordered community of life, for the state, for moral principles, humanity, and the common good.

Today one might be tempted to say that patriotism is the last refuge of the tribal religion dedicated to the worship of German, French, English and Russian Gods of Battles. Surely such a religion has nothing in common with the religion which counsels for the disciple non-resistance, unstinted forgiveness, and the elimination of all rancor?

No generation can do another generation's work for it. What we human beings can do at most is to mark out the pathway a little clearer for the generations to come after, and put legible signboards at the points where the greatest dangers have threatened us, in the hope that our posterity will read, understand, and be warned.

The only religion which seems to have a function in time of war is the tribal religion which invokes a God as the exclusive protector of the nation which calls upon him.

Our obligation to the will of God is our obligation to the laws of practical reason.
