ART AND MAGIC
SYMPATHETIC magic has in recent times become a favourite subject of scientific study. We may therefore proceed to trace the influence which this important factor has exercised on the development of art-forms without going through the labour of presenting and describing the evidence of its occurrence at the different stages of evolution. It is sufficient to refer to the copious and detailed researches of Hartland, Frazer, Béranger-Féraud, and others. What we need is only a psychological interpretation of all the facts which have been brought together by these authors.
The instances of sympathetic magic are naturally divided into two main classes, which, broadly speaking, correspond to the two types of association. But just as in psychology it is often difficult to decide whether a given associative process has its origin in a relation of contiguity or in one of similarity, so it is often an open question to which group a given superstition is to be assigned. It may even be possible to deduce both groups from one common and fundamental magical principle.
However the definitive theoretical explanation may turn out, we have for the present to uphold a distinction
