Looking in the 1991 Ace edition that says "the original uncut version" on the cover, the text of the section you have quoted is:
"What's that got to do with it? Does that make me blind and deaf to fundamental human emotion? I was saying that the crummiest painted plaster crucifix or the cheapest cardboard Christmas Creche can be sufficient symbol to evoke emotions in the human heart so strong that many have died for them and many more live for them. So the craftsmanship and artistic judgment with which such a symbol is wrought are largely irrelevant. Now here we have another emotional symbol-wrought with exquisite craftsmanship, but we won't go into that, yet. Ben, for almost three thousand years or longer, architects have designed buildings with columns shaped as female figures-it got to be such a habit that they did it as casually as a small boy steps on an ant. After all those centuries it took Rodin to see that this was work too heavy for a girl. But he didn't simply say, 'Look, you jerks, if you must design this way, make it a brawny male figure.' No, he showed it...and generalized the symbol. Here is this poor little caryatid who has tried-and failed, fallen under the load. She's a good girl-look at her face. Serious, unhappy at her failure, but not blaming anyone else, not even the gods...and still trying to shoulder her load, after she's crumpled under it.
"But she's more than good art denouncing some very bad art; she's a symbol for every woman who has ever tried to shoulder a load that was too heavy for her-over half the female population of this planet, living and dead, I would guess. But not alone women-this symbol is sexless. It means every man and every woman who ever lived who sweated out life in uncomplaining fortitude, whose courage wasn't even noticed until they crumpled under their loads. It's courage, Ben, and victory."
