the eyes of savage or barbarous peoples, it is essential to have
some acquaintance with the principles of magic and to form some
conception of the extraordinary hold which that ancient system of
superstition has had on the human mind in all ages and all
countries. Accordingly I propose to consider the subject in some
detail.



III. Sympathetic Magic


1. The Principles of Magic

IF we analyse the principles of thought on which magic is based,
they will probably be found to resolve themselves into two: first,
that like produces like, or that an effect resembles its cause;
and, second, that things which have once been in contact with each
other continue to act on each other at a distance after the
physical contact has been severed. The former principle may be
called the Law of Similarity, the latter the Law of Contact or
Contagion. From the first of these principles, namely the Law of
Similarity, the magician infers that he can produce any effect he
desires merely by imitating it: from the second he infers that
whatever he does to a material object will affect equally the
person with whom the object was once in contact, whether it formed
part of his body or not. Charms based on the Law of Similarity may
be called Homoeopathic or Imitative Magic. Charms based on the Law
of Contact or Contagion may be called Contagious Magic. To denote
the first of these branches of magic the term Homoeopathic is
