There is no subject, perhaps, on which a traveller ought to speak with less confidence, than on the religious opinions of the people he may chance to visit, in countries out of Europe, especially when those opinions are grounded on a very remote antiquity. The allegorical allusions in which they might originally have been involved, the various changes they may since have undergone, the ceremonies and types under which they are still exhibited, in their modern dress, render them so wholly unintelligible that, although they may have been founded in truth and reason, they now appear absurd and ridiculous; equally inexplicable by the people themselves who profess them, as by those who are utter strangers. The various modes, indeed, under which the Creator and Ruler of the Universe is recognised by various nations, all tending to one point, but setting out in very different directions, can only be understood and reconciled by a thorough knowledge of the language, the history, and the habits of the people; of their origin and connections with other nations; and, even after such knowledge has been obtained, it is no easy task to separate fable from metaphor, and truth from fiction. For these reasons, the religion of China appears to be fully as obscure and inexplicable as that of almost any other of the oriental nations. The language of the country, added to the jealousy of the government in admitting foreigners, have thrown almost insuperable obstacles in the way of clearing up this intricate subject; and those few, who only have had opportunities of overcoming these difficulties, were unfortunately men of that class, whose opinions were so warped by the prejudices imbibed with the tenets of their own religion, that the accounts given by them are not always to be depended upon. As I have already observed, they cannot bring themselves to speak or to write of the priests of China with any degree of temper or moderation.
