"When the Western world finally found the Andean world, their food-stuff discoveries were readily utilized with potatoes and corn rapidly becoming part of accepted agriculatural science. But the mind-stuff discoveries of the Andean world have had a very different reception, with their mind-altering materials receiving little scientific attention. When this attitude begins to change, this book will be considered a landmark."
