It is possible to imagine thinking, with its concepts, dictionaries, and organon, as shoring ‘man’ against the forces of chaos and dissolution, but we can also — when we extend this potential — see thinking as a confrontation with chaos, as allowing more of what is not ourselves to transform what we take ourselves to be.
[In addition] to the produced texts and terms, and in addition to the explicit historical presuppositions, there is an unthought or outside — the problem, desire or life of a philosophy. For Deleuze, then, reading as a philosopher requires going beyond his or her produced lexicon to the deeper logic of production from which the relations or sense of the text emerge. This sense itself can never be said; in repeating or recreating the milieu of a philosopher all we can do is produce another sense, another said.
