There may be some among the readers of this book, like the earnest engineer, who believe without question that any and all forms of construction and development are intrinsic goods, in the national parks as well as anywhere else, who virtually identify quantity with quality and therefore assume that the greater the quantity of traffic, the higher the value received. There are some who frankly and boldly advocate the eradication of the last remnants of wilderness and the complete subjugation of nature to the requirements of--not man--but industry. This is a courageous view, admirable in its simplicity and power, and with the weight of all modern history behind it. It is also quite insane. I cannot attempt to deal with it here.
