Out Milky Way is the dwelling; the nebulae are the city.

There comes an hour when protest no longer suffices; after philosophy there must be action; the strong hand finishes what the idea has sketched.

Superstition, bigotry and prejudice, ghosts though they are, cling tenaciously to life; they are shades armed with tooth and claw. They must be grappled with unceasingly, for it is a fateful part of human destiny that it is condemned to wage perpetual war against ghosts. A shade is not easily taken by the throat and destroyed.

We do not comprehend everything, but we insult nothing.

If you look in the eyes of the young, you see flame. If you look in the eyes of the old, you see light.

Do you hear the people sing Lost in the valley of the night? It is the music of a people Who are climbing to the light. For the wretched of the earth There is a flame that never dies. Even the darkest night will end And the sun will rise.

Go to sleep in peace. God is awake.
