The double title given to the book is not meant to imply that Theosophy and New Thought are approximately identical. The inclusion of the two in a Single volume is rather a matter of convenience than of logical clas sification. We recognize that, while they have distinct points of similar ity, they also exhibit quite apparent contrasts in Spirit and content. In particular the intemperate speculation and headlong Orientalism of Theosophy are but partially re?ected in New Thought. Both, however, make very high claims, and this fact justifies the subjecting of them to close scrutiny.
