“Love is not an accident. It is a delicate union of two complex, complementary puzzle pieces that have inadvertently been created by different manufacturers.”

Context: History is like a jigsaw puzzle, except every piece is from a different puzzle, and you try to make them all fit. Although you many never have a finished picture, the time you spend, I think you end up understanding at least the pieces.

Commenting on the discovery of Homo floresiensis, in a posting at McMedia.com (27 October 2004) http://www.mail-archive.com/brin-l@mccmedia.com/msg38195.html; an unsourced paraphrase replaces "go to perdition" with "go to hell".
Context: One more piece for the Great Jigsaw puzzle.
I find it truly stunning how many people can shrug off stuff like this, preferring instead a tiny, cramped cosmos just 6,000 years old, scheduled to end any-time-now in a scripted stage show of unfathomable violence and cruelty.
An ancient and immense and ongoing cosmos is so vastly more dramatic and worthy of a majestic Creator. Our brains, capable of exploring His universe, picking up His tools and doing His work, seem destined for much greater tasks than cowering in a small groups of the elect, praying that some of our neighbors will go to perdition...

God is Dead, Now Zen is the Only Living Truth (1989) YouTube video of the lecture http://www.youtube.com/watch?v=PBEIeRSLb8k
Context: It was good of Friedrich Nietzsche to declare God dead — I declare that he has never been born. It is a created fiction, an invention, not a discovery. Do you understand the difference between invention and discovery? A discovery is about truth, an invention is manufactured by you. It is man-manufactured fiction. Certainly it has given consolation, but consolation is not the right thing! Consolation is opium. It keeps you unaware of the reality, and life is flowing past you so quickly — seventy years will be gone soon. Anybody who gives you a belief system is your enemy, because the belief system becomes the barrier for your eyes, you cannot see the truth. The very desire to find the truth disappears. But in the beginning it is bitter if all your belief systems are taken away from you. The fear and anxiety which you have been suppressing for millennia, which is there, very alive, will surface immediately. No God can destroy it, only the search for truth and the experience of truth — not a belief — is capable of healing all your wounds, of making you a whole being. And the whole person is the holy person to me.
