“According to Greek mythology, humans were originally created with four arms, four legs and a head with two faces. Fearing their power, Zeus split them into two separate parts, condemning them to spend their lives in search of their other halves.”
― Plato, The Symposium

“Let me put it this way, my father believed in a righteous God. Deus volt, that was his motto- 'because God wills it.' It was the Crusaders' motto, and they went into battle and were slaughtered just like my father. And when I saw him lying dead in a pool of his own blood, I knew then that I hadn't stopped believing in God. I'd just stopped believing God cared. There might be a God, Clary, and there might not, but I don't think it matters. Either way we're on our own.”
