This 1965 edition was a translation of Chardin's "Construire la Terre". Max Bégouën, a French prehistorian and author, says in the introduction: "A luminous scientific mind and a great heart, both of them big enough to encompass the world, gave Teilhard de Chardin the vision and the power, as long ago as 1937, to discern the rising tide of destructive forces which threaten our planet. And they led him to call on all mankind to unite in building the earth -- in making the world a home for all peoples..."
That well summarizes this work of five sections. If Chardin wrote it in 1937, 86 years have passed. The remarkable thing is that his message is still, perhaps more, relevant than ever. Chardin was far ahead of his time.
