We do not have the intention of attempting a complete description of the primitive cult in what is to follow. Being preoccupied especially with reaching that which is most elementary and most fundamental in the religious life, we shall not attempt to reconstruct in detail the frequently confused multiplicity of all the ritual forms. But out of the midst of this extreme diversity of practices we should like to touch upon the most characteristic attitudes which the primitive observes in the celebration of his cult, to classify the most general forms of his rites, and to determine their origins and significance, in order that we may control and, if there is occasion, make more definite the results to which the analysis of the beliefs has led us.[999] Every cult presents a double aspect, one negative, the other positive. In reality, of course, the two sorts of rites which we denominate thus are closely associated; we shall see that they suppose one another. But still, they are different and, if it is only to understand their connection, it is necessary to distinguish them. I By definition, sacred beings are separated beings. That which characterizes them is that there is a break of continuity between them and the profane beings. Normally, the first are outside the others. A whole group of rites has the object of realizing this state of separation which is essential. Since their function is to prevent undue mixings and to keep one of these two domains from encroaching upon the other, they are only able to impose abstentions or negative acts. Therefore, we propose to give the name negative cult to the system formed by these special rites. They do not prescribe certain acts to the faithful, but confine themselves to forbidding certain ways of acting; so they all take the form of interdictions, or as is commonly said by ethnographers, of _taboos_. This latter word is the one used in the Polynesian languages to designate the institution in virtue of which certain things are withdrawn from common use[1000]; it is also an adjective expressing the distinctive characteristic of these kinds of things. We have already had occasion to show how hard it is to translate a strictly local and dialectical expression like this into a generic term. There is no religion where there are no interdictions and where they do not play a considerable part; so it is regrettable that the consecrated terminology should seem to make so universal an institution into a peculiarity of Polynesia.[1001] The expression _interdicts_ or _interdictions_ seems to us to be much more preferable. However, the word taboo, like the word totem, is so customary that it would show an excess of purism to prohibit it systematically; also, the inconveniences it may have are attenuated when its real meaning and importance have once been definitely stated.
