Read the passage carefully and answer the following questions.

"Perhaps something has occurred in the history of the concept of structure that could be called an 'event,' if this loaded word did not entail a meaning which it is precisely the function of structural—or structurality—thought to reduce or to suspect. But let me use the term 'event' anyway, employing it with caution and as if in quotation marks. In this sense, this event will have the exterior form of a rupture and a redoubling.

It would be easy enough to show that the concept of structure and structurality has always been neutralized or reduced, and this by a process of giving it a center or referring it to a point of presence, a fixed origin. The function of this center was not only to orient, balance, and organize the structure—one cannot in fact conceive of an unorganized structure—but above all to make sure that the organizing principle of the structure would limit what we might call the freeplay of the structure.

No doubt that by orienting and organizing the coherence of the system, the center of a structure permits the freeplay of its elements inside the total form. And even today the notion of a structure lacking any center represents the unthinkable itself. But the center also closes off the freeplay it opens up and makes possible.’’
