Excerpt from the book: If mind and matter have a separate existence, representing in their union certain products, as steam and the locomotive engine represent power, it is reasonable to suppose that while together they must exert certain influences the one upon the other, and such we shall find to be the case. Man is said to be in possession of five physical senses, and through them the mind is capable of being influenced by external, as well as objects within the body itself. A horrible accident, by which a mutilated object is presented to the sight, may affect the mind in the most startling manner. Fright at the appearance of some dangerous object, as poisonous serpents, wild beasts or savages, although only seen, has so powerfully affected the mind as to produce instant death.
