OK, there are people that earn money selling the books from Wallace Wattles. As you already noticed, this blog is not for profit. This is one part of the answer. We dont need to make money with it.
The other part is that we need that all people, all the world, knows Wallace Wattles and his writings. This is our contribution to the people who is walking there looking for a solution to their problems, whatever they be. These writings are a new approach to the science and practice of living. As you feel when you read the book, The Science of Getting Rich is far more than a recipe to make money, is a philosophical new way of living.
We firmly believe that if a great majority of people knows and apply the advices of this book, all the world could be more clear, more peaceful, more sane. This is the reason to give the writings from Wattles completely free, and always will be so.
