From "Out of the Silent Planet"

"A pleasure is full grown only when it is remembered. You are speaking as if the pleasure were one thing and the memory another. It is all one thing.... What you call remembering is the last part of the pleasure.... When you and I met, the meeting was over very shortly, it was nothing. Now it is growing something as we remember it. But still we know very little about it. What it will be when I remember it as I lie down to die, what it makes in me all my days till then - that is the real meeting. The other is only the beginning of it. You say you have poets in your world. Do they not teach you this?" C.S.Lewis
