“The Turtle exists. The world is a flat disc. The sun turns around it once every day, dragging its light behind it. And this will go on happening, whether you believe it is true or not. It is real. I don’t know about truth. Truth is a lot more complicated than that. I don’t think the Turtle gives a bugger whether it’s true or not, to tell you the truth.”

– Terry Pratchett – Small Gods
