Keep as few secrets as possible. The remaining ones will be easier to protect. - David Brin

Other generations perceived a plethora of swords hanging over their heads. But generally what they feared were shadows, for neither they nor their gods could actually end the world. Fate might reap an individual, a family, or even a whole nation, but not the entire world. Not then.
We, in the mid-twenty-first century, are the first to look up at a sword we ourselves forged, and know, with absolute certainty, it is real...

Each of us remains convinced that our own subjective viewpoint is more urgent than anyone else's—indeed, even more valid than the objective matrix that underlies so-called reality. After all, the subjective view is a grand theater. To be hero of an ongoing drama. It's why ideologies and bigotries survive against all evidence or logic.
Subjective obstinacy had advantages, Morris, when we were busy evolving into nature's champion egotists. It led to human mastery over the planet…and to our species nearly wiping itself out.

There were times when Robert actually envied his ancestors, who had lived in dark ignorance, before the twenty-first century, and seemed to have spent most of their time making up weird, ornate explanations of the world to fill the yawning gap of their ignorance. Back then, one could believe in anything at all.
Simple, deliciously elegant explanations of human behavior—it apparently never mattered whether they were true or not, as long as they were incanted right. "Party lines" and wonderful conspiracy theories abounded. You could even believe in your own sainthood if you wanted. Nobody was there to show you, with clear experimental proof, that there was no easy answer, no magic bullet, no philosopher's stone. Only simple, boring sanity.
How narrow the Golden Age looked in retrospect.
