A brilliant and articulate scholar, Dr. Jacob Bronowski, charts man's progress from the vantage point of the scientist/philosopher. "Among the multitude of animals which scamper, fly, burrow and swim around us, man is the only one who is not locked into his environment. His imagination, his reason, his emotional subtlety and toughness, make it possible for him not to accept the environment but to change it. And that series of inventions, by which man from age to age has remade his environment, is a different kind of evolution. I call that brilliant sequence of peaks THE ASCENT OF MAN."
