Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It is not the aim of the present writer to produce a Science of Religion, or even to speculate on the possibility of such a science being ultimately elabo rated when all the facts are fully known. He has set himself a more prosaic and less ambitious task that, namely, of collecting materials which may serve as a portion of the data, when the time comes, if it ever comes, for the construction of the science in question. A building cannot be erected without materials; a true science cannot be constructed with out ample data.
