As a general thing I do not intend to write anything that needs an apology. As for the matter Oi this book, I am sure no apology is needed. The world needs it. Devils and hob-goblins have long kept the world back from progress. In some passages the manner of presenting the truths here given may seem to border somewhat on the sarcas tic; possibly On the blasphemous. 'should any apology be needed for that, let it be found in the fact that the whole question, if it were not so ridiculous, would be a sublime sarcasm.
