This work is not an exhaustive treatise on witches and witchcraft, treated scientifically, historically and so forth. The author endeavors to produce a picture from which a general impression may be gained. He shows whence the witch came and why, as well as what she was and is; to point out how necessary she is and must be to the happiness of mankind, and how great the responsibility of those who seek to infect others with their skepticism because they do not believe in her.
