“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.”
― Neal Stephenson, Cryptonomicon

“All happy families are alike; each unhappy family is unhappy in its own way.”
― Leo Tolstoy , Anna Karenina

“If everyone fought for their own convictions there would be no war.”
