I did this because, limited by space, I felt I infused enough of the book with big wall ethics that these essays could be out of the print book as long as I put them in the eBook and all over the web site (which I did). But, as I now realize based on your feedback, a good talk with Jesse and my own reflection, you can't have enough essays and discussion on big wall ethics and wilderness ethics. Most of you get it: leave no trace... period. But there are some folks that could use either an introduction to Wilderness and low impact climbing or at least a refresher.
However, I fell short on really driving home the Wilderness ethic. Namely, I put most of the info (and too little of it) in the Rules Section of The Introduction (see page 14). While Wilderness is the rule on all Yosemite big walls. It goes well beyond that. The idea of Wilderness and leave no trace was established and refined by climbers (Muir, Brower, Chouinard, Frost, etc etc). It is not a rule that was imposed on climbers as much as a higher way of being in the outdoors that climbers helped establish.
Needless to say, Big Walls 4th Edition Print book will have these chapters back in. But, in the meantime
Sorry, but Dingus is going to get on here and explain to you ethics are all relative - as in relative to which way the wind blows at the moment and in any case you simply can't constrain the youngsters with such tired stuff as this because it will stifle and damage their creative impulses. Besides, why bother anyway, what with all the Winnebagos passing through.
