Baruch Spinoza on Hope

"I, too, have been in the underworld, like Odysseus, and shall be there often yet, and not only rams have I sacrificed to be able to speak with a few of the dead, but I have not spared my own blood. Four pairs it was that did not deny themselves to my sacrifice: Epicurus and Montaigne, Goethe and Spinoza, Plato and Rousseau, Pascal and Schopenhauer. With these I must come to terms when I have long wandered alone; they may call me right and wrong; to them will I listen when in the process they call each other right and wrong."

"I had hoped that out of so many stories you would at least have produced one or two, which could hardly be questioned, and which would clearly show that ghosts or spectres exist. The case you relate... seems to me laughable. In like manner it would be tedious here to examine all the stories of people, who have written on these trifles. To be brief, I cite the instance of Julius Caesar, who, as Suetonius testifies, laughed at such things and yet was happy. ...And so should all who reflect on the human imagination, and the effects of the emotions, laugh at such notions; whatever Lavater and others, who have gone dreaming with him in the matter, may produce to the contrary."
