I shall call them, by way of contrast to utopias, heterotopias.

The enigma is solved. The heterotopia was defined long before we got to this point. Foucault reaffirms his antithesis and continues in his explanation of the heterotopia, giving examples and outlying principles. But in between the text, in the streographic space of writing, Foucault has already told us what we needed to know about heterotopias.

There's only one more thing left to do.

Thank you.
