"We venture to say a few words in explanation of the plan of this work. Its object is not to force upon the public the personal views or theories of its author; nor has it the pretensions of a scientific work, which aims at creating a revolution in some department of thought. It is rather a brief summary of the religions, philosophies, and universal traditions of human kind, and the exegesis of the same, in the spirit of those secret doctrines, of which none — thanks to prejudice and bigotry — have reached Christendom in so unmutilated a form, as to secure it a fair judgment. Introduction"
