Man's most human characteristic is not his ability to learn, which he shares with many other species, but his ability to teach and store what others have developed and taught him.
Margaret MeadIt was not until we saw the picture of the earth, from the moon, that we realized how small and how helpless this planet is - something that we must hold in our arms and care for.
Margaret MeadEven very recently, the elders could say: 'You know, I have been young and you never have been old.' But today's young people can reply: 'You never have been young in the world I am young in, and you never can be.' ... the older generation will never see repeated in the lives of young people their own unprecedented experience of sequentially emerging change. This break between generations is wholly new: it is planetary and universal.
