Perspective in Humanism, planned and edited by Ruth Nanda Anshen, presents a series of books by the world's foremost thinkers here assembled in a collective effort to understand more clearly the unlimited and unprecedented choices for good and evil that dominate our time.  The authors in this Series are reacting to the existing threat to man's physical, spiritual and intellectual life by expressing in their respective books their common concern for the destiny of the human race.  Man has for the first time in human history intervened in the process of evolution and now must direct it. To do this he must develop the wisdom to make judgments of value.  These volumes try to overcome the split between feeling and thought, meaning and function and to show the kinship between subject and object.  The humanist principle directing technological progress is th only bond able to unite the multiple disciplines and various cultures.
