"“How to achieve a more robust homeostasis. Just because it’s difficult to do doesn’t make the principal science unsolvable.” “So not unnatural at all,” Holden said, tipping a little more wine from the bottle into the doctor’s glass. “Meaningless term,” Cortázar said. “Humans arose inside nature. We’re natural. Everything we do is natural. The whole idea that we are different in category is either sentimental or religious. Irrelevant from a scientific perspective.” “So if we get to a place that we can all live forever, that’s not unnatural? Holden sounded genuinely curious. Cortázar leaned in toward the prisoner, gesturing with his left hand while he swirled his glass in his right. “The only limits on us are what we can do. It’s perfectly natural to seek personal benefit. It’s perfectly natural to give advantages to your own offspring and withhold them from others. It’s perfectly natural to kill your enemies. That’s not even outlier behavior. That’s all in the middle of the bell curve all the time.”"
