Part of being a sentient human is the ability to anticipate others' mental states - to say "Fred's going to hate this but Jane would love it."

Wait a minute, Juanita. Make up your mind. This Snow Crash thing—is it a virus, a drug, or a religion?" Juanita shrugs. "What's the difference?

I actually don't think that there is a connection between the survival instinct and a hunger for immortality.

The franchise and the virus work on the same principle, what thrives in one place will thrive in another. You just have to find a sufficiently virulent business plan, condense it into a three-ring binder ― its DNA ― Xerox it, and embed it in the fertile line of a well-traveled highway, preferably one with a left turn lane. Then the growth will expand until it runs up against its property lines.

If the item of stolen property had been anything other than a book, it would have been confiscated. But a book is different - it is not just a material possession but the pathway to an enlightened mind, and thence to a well-ordered society.

At the beginning of the project, I wasn't certain that I could come up with an engaging storyline and cast of characters in this world, so I had a strong bias toward actually writing, and worrying about research later. In other words, I was afraid that I'd devote a year or two of my life to grinding through Kant and Husserl, then discover that there simply was no novel to be written here.

A species has to become pretty intellectually advanced in order to grasp the concept of death in the abstract, and to dream up the idea of immortality. Long before that (in evolutionary terms) all species with brains have the survival instinct in some form. So, I am just saying that there are many existent proofs of species that have one, but not the other.
