After my dad died, I remembered reading this a few years ago. It stuck out to me at the time when I read it and was the main section of the book that I learned from. Our memories definitely play an important role in our lives.
"A pleasure is full grown only when it is remembered. You are speaking, Hman, as if the pleasure were one thing and the memory another. It is all one thing. The seroni could say it better than I say it now. Not better than I could say it in a poem. What you call remembering is the last part of the pleasure, as the crah is the last part of a poem. 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?"
"Perhaps some of them do," said Ransom. "But even in a poem does a hross never long to hear one splendid line over again?"
"the poem is a good example. For the most splendid line becomes fully splendid only by means of all the lines after it; if you went back to it you would find it less splendid than you thought. You would kill it. I mean in a good poem."
"Undoubtedly," he said. "Maleldil made us so. How could there ever be enough to eat if everyone had twenty young? And how could we endure to live and let time pass if we were always crying for one day or one year to come back - if we did not know that every day in a life fills the whole life with expectation and memory and that these are that day?"
