Three passions,simple but overwhelmingly strong,have governed my life: the longing for love,the search for knowledge,and unbearable pity for the suffering of mankind.These passions,in a wayward course,over a deep ocean of anguish,reaching to the very verge of despair.
Love and knowledge,so far as they were possible,led upward toward the heavens.But always pity brought me back to earth.Echoes of cries of pain reverberate in my heart.
-------Bertrand Russell
