For the last couple of centuries, philosophers and psychologists have racked their brains over the question whether there is such a thing as pure selflessness. But to be honest, that whole debate doesn’t really interest me. Because just imagine living in a world where you got a sick feeling every time you performed a kind act. What sort of hell would that be?

The wonderful fact is that we live in a world where doing good also feels good. We like food because without food we’d starve. We like sex because without sex we’d go extinct. We like helping because without each other we’d wither away. Doing good typically feels good because it is good.
