While literature is rife with the terror of a bad conscience – Sophocles’ Oedipus Rex, William Shakespeare’s Macbeth, Edgar Allen Poe’s The Tell-Tale Heart and Oscar Wilde’s The Picture of Dorian Gray – there is little evidence that we actually care about wronging others. We aren’t as smart as we think and end up believing that selfishness and greed is what keeps us alive. Children are taught all sorts of other good things – sharing and caring and all that – but they learn by watching how adults behave. The message is clear: Teachers and parents don’t practice what they preach; the wealthy stay rich through manipulation, and leaders maintain their power through collusion.

We want what we have, and we want whatever everyone else has too.Bring on the flood.
