"The happy man is the man...whose personality is neither divided against itself or pitted against the world. Such a man feels himself a citizen of the universe, enjoying freely the spectacle that it offers and the joys that it affords, untroubled by the thought of death because he feels himself not really separate from those who will come after him. It is in such profound instinctive union with the stream of life that the greatest joy is to be found."
Bertrand Russell
