Query: Torch edition of "The Transformaton of Man"

Like all Mumford's books, there are such erudite analogies in this one that you have new tangents to explore. As Volume Seven of "World Perspectives" it was first printed in hard cover in 1956. The Torch edition was published in 1972 with his new intro acknowledging a widening of his own perceptions and that ends, "The more hopeless our present situation seems, confronted...by both ecologically unbalanced environments and psychological unbalanced minds, the more imperative it is not to lose hope... The coming generation still has man's oldest [option], cultivating the arts that make man human."
