This fascinating book continues the story begun in the bestselling and critically acclaimed book The Mind in the Cave. Drawing on the latest research and recent discoveries, the authors skilfully link material on human consciousness, imagery and belief systems to propose provocative new theories about the causes of an ancient revolution in cosmology, the origins of social complexity and even the drive behind the domestication of plants and animals. In doing so they create a fascinating neurological bridge to the mysterious thought-lives of the past and reveal the essence of a momentous period in human history.

The rock paintings and engravings of southern Africa have long been considered obscure, yet research has managed since to piece together that message, and we now know that this beautiful and detailed art tells us about the religious experiences of the San (bushmen) who made it: centuries ago the San believed that the art carried messages from the spirit world. This book traces the story behind that research, how it started, its failures and successes, and some of its debates, linking the art to the people who made it.

This book chronicles the history of All American Aviation of western Pennsylvania, a commercial airline pioneer. The brainchild of self-styled inventor Dr. Lytle S. Adams and Richard C. du Pont, the company began as an airmail delivery carrier, taking advantage of the Experimental Air Mail Act passed by Congress in 1938. "T""he Airway to Everywhere "relates the exciting early days of airmail delivery--hair-raising tales of courageous pilots who scooped mail bags tethered to wires strung between poles on makeshift airfields. The story of this airline is placed within the context a typical twentieth-century American business pattern-where technological innovation is followed by development and commercial application, followed by government subsidies and corporate takeovers. In that vein, All American Aviation would become Allegheny Airlines, and later, U.S. Air.

Rock art images around the world are often difficult for us to decipher as modern viewers. Based on authentic records of the beliefs, rituals and daily life of the nineteenth-century San peoples, and of those who still inhabit the Kalahari Desert, this book adopts a new approach to hunter-gatherer rock art by placing the process of image-making within the social framework of production. Lewis-Williams shows how the San used this imagery not simply to record hunts and the animals that they saw, but rather to sustain the social network and status of those who made them. By drawing on such rich and complex records, the book reveals specific, repeated features of hunter-gatherer imagery and allows us insight into social relations as if through the eyes of the San themselves.
