Memory and Imagination had a discussion as to which was the greater. "Without me," said Memory, "your buildings, your fine castles, would all go down. I alone give you power to retain them."
Without me, said Imagination, "there would be no use of retaining them, for, indeed, they wouldn't be there. I am the great builder."
And I the great recorder.
It appears, then, that no one of us is greater than the other. Yet I would not change places with you.
Why not? said Memory.
Because, replied Imagination, "without you I can still keep on creating over and over."
At the end of a year Memory came back.
What have you done? asked Memory.
Nothing, said Imagination.
And you were wrong when you said that without me you could still go on creating.
Yes. I did not realize how dependent I was upon you. What have you been doing during the year?
Reviewing some old friends. That was all I could do.
Then we are practically equal.
"Yes. Let us live together hereafter in harmony, carrying on our door this legend:
  There is no Memory without
      Imagination,
  And no Imagination without
      Memory.
"
