We know very little, and yet it is astonishing that we know... - Bertrand Russell

"To like many people spontaneously and without effort is perhaps the greatest of all sources of personal happiness."

"The good life is one inspired by love and guided by knowledge."

"Those who have never known the deep intimacy and the intense companionship of happy mutual love have missed the best thing that life has to give."

"Man needs, for his happiness, not only the enjoyment of this or that, but hope and enterprise and change."

"Extreme hopes are born from extreme misery."
