Do not pass by my epitaph, traveler.
But having stopped, listen and learn, then go your way.
There is no boat in Hades, no ferryman Charon,
No caretaker Aiakos, no dog Cerberus.
All we who are dead below
Have become bones and ashes, but nothing else.
I have spoken to you honestly, go on, traveler,
Lest even while dead I seem loquacious to you.

Roman Tombstone

God is dead. God remains dead. And we have killed him. How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives:  Firedrich Nietzsche

Men never do evil so completely and cheerfully as when they do it from religious conviction: Blaise Pascal

Battle not with monsters
lest ye become a monster
and if you gaze into the abyss
the abyss gazes into you.

Friedrich Nietzsche:

There is no great genius without some touch of madness. Seneca

Now, now my good man, this is no time for making enemies.

Voltaire on his deathbed in response to a priest asking that he renounce Satan

We have enslaved the rest of animal creation and have treated our distant cousins in fur and feathers so badly that beyond doubt, if they were to formulate a religion, they would depict the Devil in human form.

William Ralph Inge
