It should be superfluous, at this time of day, to defend such studies as these from the criticisms which have from time to time been brought against them. I remember my old friend and former teacher, Wan `Abdullah, a Singapore Malay of Trengganu extraction and Arab descent, a devout and learned Muhammadan and a most charming man, objecting to them on the grounds, first, that they were useless, and, secondly, which, as he emphatically declared, was far worse, that they were perilous to the soul's health. This last is a point of view which it would hardly be appropriate or profitable to discuss here, but a few words may as well be devoted to the other objection. It is based, sometimes, on the ground that these studies deal not with "facts," but with mere nonsensical fancies and beliefs. Now, for facts we all, of course, have the greatest respect; but the objection appears to me to involve an unwarrantable restriction of the meaning of the word: a belief which is actually held, even a mere fancy that is entertained in the mind, has a real existence, and is a fact just as much as any other. As a piece of psychology it must always have a certain interest, and it may on occasions become of enormous practical importance. If, for instance, in 1857 certain persons, whose concern it was, had paid more attention to facts of this kind, possibly the Indian Mutiny could have been prevented, and probably it might have been foreseen, so that precautionary measures could have been taken in time to minimise the extent of the catastrophe. It is not suggested that the matters dealt with in this book are ever likely to involve such serious issues; but, speaking generally, there can be no doubt that an understanding of the ideas and modes of thought of an alien people in a relatively low stage of civilisation facilitates very considerably the task of governing them; and in the Malay Peninsula that task has now devolved mainly upon Englishmen. Moreover, every notion of utility implies an end to which it is to be referred, and there are other ends in life worth considering as well as those to which the "practical man" is pleased to restrict himself. When one passes from the practical to the speculative point of view, it is almost impossible to predict what piece of knowledge will be fruitful of results, and what will not; prima facie, therefore, all knowledge has a claim to be considered of importance from a scientific point of view, and until everything is known, nothing can safely be rejected as worthless.
