doubted whether in regard to many of the lower races we shall ever
arrive at more than probable conjectures.

Since the last edition of _The Golden Bough_ was published some thirteen
years ago, I have seen reason to change my views on several matters
discussed in this concluding part of the work, and though I have called
attention to these changes in the text, it may be well for the sake of
clearness to recapitulate them here.

In the first place, the arguments of Dr. Edward Westermarck have
satisfied me that the solar theory of the European fire-festivals, which
I accepted from W. Mannhardt, is very slightly, if at all, supported by
the evidence and is probably erroneous. The true explanation of the
festivals I now believe to be the one advocated by Dr. Westermarck
himself, namely that they are purificatory in intention, the fire being
designed not, as I formerly held, to reinforce the sun's light and heat
by sympathetic magic, but merely to burn or repel the noxious things,
whether conceived as material or spiritual, which threaten the life of
man, of animals, and of plants. This aspect of the fire-festivals had
not wholly escaped me in former editions; I pointed it out explicitly,
but, biassed perhaps by the great authority of Mannhardt, I treated it
as secondary and subordinate instead of primary and dominant. Out of
deference to Mannhardt, for whose work I entertain the highest respect,
and because the evidence for the purificatory theory of the fires is
perhaps not quite conclusive, I have in this edition repeated and even
reinforced the arguments for the solar theory of the festivals, so that
the reader may see for himself what can be said on both sides of the
question and may draw his own conclusion; but for my part I cannot but
think that the arguments for the purificatory theory far outweigh the
arguments for the solar theory. Dr. Westermarck based his criticisms
