That's ad hominem, though. Happy, happy, happy: a babyish purpose of life. Puppies are happy, as are infants--until they're not. They're often happy because they're content. Why? Because they don't know anything. They can't think deep thoughts. Knowledge makes us discontent as a species. So happiness is for sheep, not shepherds.
