"Is Earth the ideal planet for life? What is the future of life in our universe? We often imagine our place in the universe in the same way we experience our lives and the places we inhabit. We imagine a practically static eternal universe where we, and life in general, are born, grow up, and mature; we are merely one of numerous generations."
"Many of the people here worry about what life is, but maybe in a slightly more general way, not just ribosomes, but inorganic life. Would we know it if we saw it? It's important as we go and discover other worlds, as we start creating more complicated robots, and so forth, to know, where do we draw the line?"
"If you program a computer at random, it will start producing other computers, other ways of computing, other more complicated, composite ways of computing. And here is where life shows up. Because the universe is already computing from the very beginning when it starts, starting from the Big Bang, as soon as elementary particles show up. Then it starts exploring — I'm sorry to have to use anthropomorphic language about this, I'm not imputing any kind of actual intent to the universe as a whole, but I have to use it for this to describe it — it starts to explore other ways of computing."
"The essential idea is that you separate metabolism from replication. We know modern life has both metabolism and replication, but they're carried out by separate groups of molecules. Metabolism is carried out by proteins and all kinds of other molecules, and replication is carried out by DNA and RNA. That maybe is a clue to the fact that they started out separate rather than together. So my version of the origin of life is that it started with metabolism only."
"I'll start with a topic that is called an inside-outside view of the planning fallacy. And it starts with a personal story, which is a true story."
"As I look through the structure of the words and the structure of the sentences, it just becomes clear that they don't have recursion. If recursion is what Chomsky and Mark Hauser and Tecumseh Fitch have called 'the essential property of language', the essential building block—in fact they've gone so far as to claim that that might be all there really is to human language that makes it different from other kinds of systems—then, the fact that recursion is absent in a language — Pirahã — means that this language is fundamentally different from their predictions."
"I'm always running out of metaphors to try and explain what the difficulty is. But suppose you took Scrabble sets, or any word game sets, blocks with letters, containing every language on Earth, and you heap them together and you then took a scoop and you scooped into that heap, and you flung it out on the lawn there, and the letters fell into a line which contained the words “To be or not to be, that is the question,” that is roughly the odds of an RNA molecule, given no feedback — and there would be no feedback, because it wouldn't be functional until it attained a certain length and could copy itself — appearing on the Earth."
"This text sees Judas dying as a martyr—because here the other disciples hate him so much that they kill him! But the Gospel of Judas challenges the idea that God wants people to die as martyrs—just as it challenges the idea that God wanted Jesus to die. Whoever wrote this gospel—and the author is anonymous—is challenging church leaders who teach that. It's as if an imam were to challenge the radical imams who encourage "martyrdom operations" and accuse them of complicity in murder—the Gospel of Judas shows "the twelve disciples"—stand-ins for church leaders—offering human sacrifice on the altar—and doing this in the name of Jesus! Conservative Christians hate gospels like this—usually call them fakes and the people who publish them (like us) anti Christian. There was a great deal of censorship in the early Christian movement—especially after the emperor became a Christian, and made it the religion of the empire—and voices like those of this author were silenced and denounced as "heretics" and "liars." The story of Jesus was simplified and cleaned up—made "orthodox.""
