Before I introduce the subject of this article, I should confess that its subject is the subject itself. The question of the subject always brings along a question of location and, therefore, a question of topology. Consequently, what we have here as a subject is a subject which does not conform to the rules of being a subject and hence this subject‐non‐subject demands an approach where topology and atopology should be put in a complementary relationship rather than an oppositional one. Without cutting the long word short, or without putting our subject under protection, or without opening what cannot be opened, we can at least say that our subject here is an umbrella, an umbrella which, being the subject of three different persons, can be seen, though only at the beginning, as the subject of that which incessantly echoes the question of localisability.
