In undertaking to write a book on these subjects myself, I wholly disclaim the pretension of _teaching_ or of enforcing opinions. My object is to suggest inquiry and stimulate observation, in order that we may endeavor, if possible, to discover something regarding our psychical nature, as it exists here in the flesh; and as it is to exist hereafter, out of it. If I could only induce a few capable persons, instead of laughing at these things, to look at them, my object would be attained, and I should consider my time well spent.
