The following is not exactly a dialogue, although in places it resembles an exchange that might actually have taken place between two interlocutors. Yet, one will notice as well a certain inconstancy in this resemblance. It is perhaps a typographical rather than a dialogic form that has imposed itself here, the back and forth of more than one 'voice' requiring the convention of blank intervals across the page. These, in turn, could be thought of as the slats of a Venetian blind, or a jalousie, which partially obstructs the view.
