“Every aspect of Nature reveals a deep mystery and touches our sense of wonder and awe. Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.”
― Carl Sagan, Cosmos

“It is said that your life flashes before your eyes just before you die. That is true, it's called Life.”
― Terry Pratchett, The Last Continent

“Everything in life is just for a while.”
― Philip K. Dick, A Scanner Darkly

“When we don't know who to hate, we hate ourselves.”
― Chuck Palahniuk, Invisible Monsters
