“But there is one more reason to protect other species. One seldom if ever mentioned. Perhaps we are the first to talk and think and build and aspire, but we may not be the last. Others may follow us in this adventure. Some day we may be judged by just how well we served, when alone we were Earth’s caretakers.”

“The worst mistake of first contact, made throughout history by individuals on both sides of every new encounter, has been the unfortunate habit of making assumptions. It often proved fatal.”

“Predicting has a spotty record in science fiction. I've had some failures. On the other hand, I also predicted the fall of the Berlin Wall and the rise of fundamentalist Islam... and I'm not happy to be right in all of those cases.”

“When it comes to privacy and accountability, people always demand the former for themselves and the latter for everyone else.”

“Indeed, the maligned American pastime of baseball may be by-far the greatest and best sport by one criterion, when it comes to emulating and training for genuinely useful Neolithic skills! Think about it. The game consists of lots of patient waiting and watching (stalking), throwing with incredible accuracy and speed, sprinting, dodging... and hitting moving objects real hard with clubs! And arguing. Hey, what else could you possibly need? Now, tell me, how do soccer or basketball prepare you to survive in the wild, hm?”

“It is a total mystery how we evolved minds capable of piloting cars through wild maneuvers using a wrist to steep while shouting at a cell phone. The creationists are fools for focusing on animal evolution. Darwin explains nature! He has more difficulty explaining us.”

“The health of an enlightened and progressive society is measured by how vibrant is its science fiction, since that is where true self-critique and appraisal and hope lie.”

“As sci-fi writer Theodore Sturgeon said, 90 percent of everything is crap. But science fiction has not been forgiven for its crap. The reason is that science fiction inherently distrusts the 'eternal verities' on which literature graduates base their doctoral dissertations. Literature departments were uncomfortable with that. But things change.”

“I consider Yoda to be just about the most evil character that I’ve ever seen in the history of literature. I have gotten people into tongue-tied snits unable to name for me one scene in which Yoda is ever helpful to anybody, or says anything that’s genuinely wise. 'Do or do not, there is no try.' Up yours, you horrible little oven mitt! 'Try' is how human beings get better. That’s how people learn, they try some of their muscles, or their Force mechanism heads in the right direction, that part gets reinforced and rewarded with positive feedback, which you never give. And parts of it get repressed by saying, 'No, that you will not do!' It is abhorrent, junior high school Zen. It’s cartoon crap.”

“Your neighbors are not all sheep. Your political opponents are not all evil or fools. Try talking to those you despise. They are your fellow citizens. And together, we are not lesser than any "greatest generation.".”

“Beware of self-indulgence. The romance surrounding the writing profession carries several myths: that one must suffer in order to be creative; that one must be cantankerous and objectionable in order to be bright; that ego is paramount over skill; that one can rise to a level from which one can tell the reader to go to hell. These myths, if believed, can ruin you. If you believe you can make a living as a writer, you already have enough ego.”
