I believe that one can and must hope for a sane society that furthers man's capacity to love his fellow men, to work and create, to develop his reason and his objectivity of a sense of himself that is based on the experience of his productive energy. I believe that one can and must hope for the collective regaining of a mental health that is characterized by the capacity to love and to create.

There is no meaning to life except the meaning man gives his life by the unfolding of his powers.
