If the spiritual values of human existence at its highest term of development and achievement do not endure, amidst all the changes and chances of this mortal universe, there seems to be no stable or coherent meaning in existence. Then the universe is irrational--indeed it is no universe at all.

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.

Might does not make right, but right demands that those who hold to it should defend it with all their might.

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

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?

Science ... is organized common sense.

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.
