Once upon a time, there was a fish. And just because he was a fish, he had lived all his life in the water and knew nothing whatsoever about anything else but water. And one day as he swam about in the lake where all his days had been spent, he happened to meet a turtle of his acquaintance who had just come back from a little excursion.
“Good day, Mr. Turtle!” said the fish. “I have not seen you for a long time. Where have you been?”
“Oh”, said the turtle, “I have just been on dry land.”
“On dry land!” exclaimed the fish. “What do you mean by that? There is no dry land. I have never seen such a thing. Dry land does not exist.”
“Well,” said the turtle good-naturedly. “If you want to think so, of course, you may; there is no one who can hinder you. But that’s where I’ve been, all the same.”
“Oh, come,” said the fish. “Try to talk sense. How is this dry land? Is it all wet?”
“No, it is not wet,” said the turtle.
“Is it clear, so that light can come through it?” asked the fish.
“No, it is not clear. Light cannot come through it,” said the turtle.
“Is it soft and yielding, so that I can swim through it?”
“No, it is not soft and yielding. You could not swim in it.”
“Does it move or flow in streams?”
“No, it neither moves nor flows in streams.”
“Does it ever rise up into waves then, with white foam in them?” asked the fish, impatiently.
“No!” replied the turtle, truthfully. “It never rises up into waves, that I have seen.”
“There now,” exclaimed the fish triumphantly. “Didn’t I tell you that this land of yours does not exist? I have just asked, and you have answered that it is neither wet nor cool, not clear nor soft, and that it does not flow in streams nor rise up into waves. And if it isn’t a single one of these things, what else is it but nothing?”
“Well, well”, said the turtle, “If you are determined to think that dry land does not exist, I suppose you must just go on thinking so. But anyone who knows what is water and what is land would say you were just a silly fish.”
And with that, the turtle turned away and, leaving the fish behind in his little pond of water, set out on another excursion over the dry land that does not exist…
