The sciences are the 'how,' and the humanities are the 'why' - why are we here, why do we believe in the things we believe in. I don't think you can have the 'how' without the 'why.'
George LucasI wanted Yoda to be the traditional kind of character you find in fairy tales and mythology. And that character is usually a frog or a wizened old man on the side of the road. The hero is going down the road and meets this poor and insignificant person. The goal or lesson is for the hero to learn to respect everybody and to pay attention to the poorest person because that's where the key to his success will be.
