Moreover, the world of sacred things is, by definition, a world apart. Since it is opposed to the profane world by all the characteristics we have mentioned, it must be treated in its own peculiar way: it would be a misunderstanding of its nature and a confusion of it with something that it is not, to make use of the gestures, language and attitudes which we employ in our relations with ordinary things, when we have to do with the things that compose it. We may handle the former freely; we speak freely to vulgar beings; so we do not touch the sacred beings, or we touch them only with reserve; we do not speak in their presence, or we do not speak the common language there. All that is used in our commerce with the one must be excluded from our commerce with the other. But if this explanation is not inexact, it is, nevertheless, insufficient. In fact, there are many beings which are the objects of respect without being protected by systems of rigorous interdictions such as those we have just described. Of course there is a general tendency of the mind to localize different things in different places, especially when they are incompatible with each other. But the profane environment and the sacred one are not merely distinct, but they are also closed to one another; between them there is an abyss. So there ought to be some particular reason in the nature of sacred things, which causes this exceptional isolation and mutual exclusion. And, in fact, by a sort of contradiction, the sacred world is inclined, as it were, to spread itself into this same profane world which it excludes elsewhere: at the same time that it repels it, it tends to flow into it as soon as it approaches. This is why it is necessary to keep them at a distance from one another and to create a sort of vacuum between them.
