ABSTRACT
So far an attempt has been made to provide an initial indication of the character of closure. It is time to turn to the manner in which layers of closure are combined to form systems of closure.These systems of closure, as a result of the realisation of material, are able to intervene in openness. In addition to describing the operation of elementary systems of closure an attempt will be made to offer a preliminary outline of the operation of biological systems of closure and the human system of closure in particular. The purpose of such a description is to indicate how in principle a system of closure might be capable of providing experience and language; it is not intended to offer a detailed account of the human system of closure for such a description will require a dialogue between the framework offered here and extensive empirical observation of a kind that is not currently available to us. Moreover, the description offered is itself a linguistic closure or set of closures and is thus itself the outcome of the system it itself describes.
