A review of the first egoist book in America, from a spiritualist, new age journal titled NOW: A Journal of Affirmation, Vol. VI.  No. 7, of March 1906.

findacenter.com defines “New Thought” as “…a spiritual path or movement formed primarily by Suffragettes. Abolitionists and Free Thinkers guided by Core Concepts which include: co-creation, human rights and scientific thinking.”

wikipedia: The New Thought movement was based on the teachings of Phineas Quimby (1802–1866), an American mesmerist and healer. Quimby had developed a belief system which included the tenet that illness originated in the mind as a consequence of erroneous beliefs and that a mind open to God’s wisdom could overcome any illness. His basic premise was:

The trouble is in the mind, for the body is only the house for the mind to dwell in […] Therefore, if your mind had been deceived by some invisible enemy into a belief, you have put it into the form of a disease, with or without your knowledge. By my theory or truth, I come in contact with your enemy, and restore you to health and happiness. This I do partly mentally, and partly by talking till I correct the wrong impression and establish the Truth, and the Truth is the cure.

Philosophy of Egoism, by James L. Walker.

N. Y. City, and by H. P. Replogle, Box 1307, Denver, Colo. Price, 75c and 35c, according
to binding. This book is a labor of love on part of the publishers. It may be classed as a treatise upon Philosophic Anarchy, though the author rather denys this and calls it “Individualism.” The author was a deep and logical thinker. Any one accepting his premises will be carried along to his conclusions. It is good reading for one to sharpen his mental teeth upon, because it is full of philosophical reasoning. Personally I am not able to decide upon its value, for it is the antithesic of my “Soul Culture” philosophy. That the author is a
man well posted and one who fortifies his positions by sound reasoning is evident on every page. The place and use of such reasoning the world must decide.
