“The difference between a Miracle and a Fact is exactly the difference between a mermaid and a seal.”

“We must remember that there is a great difference between a myth and a miracle. A myth is the idealization of a fact. A miracle is the counterfeit of a fact. There is the same difference between a myth and a miracle that there is between fiction and falsehood -- between poetry and perjury. Miracles belong to the far past and the far future. The little line of sand, called the present, between the seas, belongs to common sense to the natural.”

“The difference between hope and despair is a different way of telling stories from the same facts.”

“There's a world of difference between truth and facts. Facts can obscure truth.”

“and don't tell me there isn't one bit of difference between null and space, because that's exactly how much difference there is”

“The sole difference between myself and a madman is the fact that I am not mad!”
