Let's set the existence-of-God issue aside for a later volume, and just stipulate that in some way, self-replicating organisms came into existence on this planet and immediately began trying to get rid of each other, either by spamming their environments with rough copies of themselves, or by more direct means which hardly need to be belabored. Most of them failed, and their genetic legacy was erased from the universe forever, but a few found some way to survive and to propagate.

They knew many things but had no idea why. And strangely this made them more, rather than less, certain that they were right.

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.

In the case of Anathem, most of the research had to do with philosophy and metaphysics. Reading this sort of thing has never been my strong suit, so I actually had to be somewhat more "organized and results-driven" than is my habit. I just made up my mind that I was going to have to read some of these philosophy tomes, and I forced myself to read something like 10 pages a day until I had bashed my way through them.

Whenever I get distracted or bored, my eyes wander over to that chalkboard and I read the words. Some of them grow on me, and others annoy me. I attack the latter with eraser and chalk, and keep nudging at them until I like the way they look and sound. Others never make the cut at all and simply get erased. Perhaps one day I will sell these on eBay to RPG players who need names for characters or alien races.

The only thing that can effect a big change in personality is something that physically rewires the brain and/or alters the body's chemical milieu.

Jad said, "The leakage was forcing choices, the making of which in no way improved matters." Okay. So we were, in effect, locked in a room with a madman sorcerer. That clarified things a little.
