Protect your freedom!

Safe Energy Source for the Future

First and Second Editions:

This book is being published in physical and digital form under a specific license. The programs used to create it are all free software. This is due to ethical considerations of the digital world in relation to copyright, and it tries to be a contribution to free culture. Therefore I wish to dedicate this book to two prominent figures who have promoted free culture in and out of the computer world: Richard M. Stallman and Lawrence Lessig. Thanks to them, a door can be opened to extend freedom in the philosophical world. I hope most philosophers will do the same.


Third Edition:

This third edition is dedicated to the Asociación de Estudiantes de Filosofía of the University of Puerto Rico in Río Piedras.
