The repute and influence of Teilhard de Chardin continues to grow since translations from the French have made his works available to English and American readers. The present small volume adds new dimensions to his system of thought through its concentration upon one aspect: the future of Man in cosmic history. The author begins by reaffirming his solidarity with those who believe in the ""mobility of things,"" as contrasted with those whom he calls the ""immoblists."" ""The Cosmic did once move...in its very being."" Man arose out of that cosmic movement to become the bearer in whom the evolutionary capacity of the universe has concentrated and confined itself. He stands at the beginning of a new era in which the ""planetization"" of mankind is becoming a realization. His ultimate end lies in the fact that thought-man's capacity for reflection and re-flexion-breaks free from the material world. As in his earlier works, the author's terminology puts the persistence of the reader to test. But the sweep and fervor of vision here makes for rare and inspiring reading. This book, along with others of Teilhard de Chardin, is not to be missed by those who are to understand the cosmic view taking shape today.
