For the same reason there is nowhere to begin to trace the sheaf or the graphics of differance. For what is put into question is precisely the quest for a rightful beginning, an absolute point of departure, a principal responsibility. The problematic of writing is opened by putting into question the value of the arkhe. What I will propose here will not be elaborated simply as a philosophical discourse, operating according to principles, postulates, axioms, or definitions, and proceeding along the discursive lines of a linear order of reasons. In the delineation of differance everything is strategic and adventurous. Strategic because no transcendent truth present outside the field of writing can govern theologically the totality of the field. Adventurous because this strategy is a not simple strategy in the sense that strategy orients tactics according to a final goal, a telos or theme of domination, a mastery and ultimate reappropriation of the development of the field. Finally, a strategy without finality, what might be called blind tactics, or empirical wandering if the value of empiricism did not itself acquire its entire meaning in opposition to philosophical responsibility. If there is a certain wandering in the tracing of differance, it no more follows the lines of philosophical-logical discourse than that of its symmetrical and integral inverse, empirical-logical discourse. The concept of play keeps itself beyond this opposition, announcing, on the eve of philosophy and beyond it, the unity of chance and necessity in calculations without end.

~ Jacques Derrida

Marx was troubled by the question of why ancient Greek art retained an ‘eternal charm’, even though the social conditions which produced it had long passed; but how do we know that it will remain ‘eternally’ charming, since history has not yet ended? Let us imagine that by dint of some deft archaeological research we discovered a great deal more about what ancient Greek tragedy actually meant to its original audiences, recognized that these concerns were utterly remote from our own, and began to read the plays again in the light of this deepened knowledge. One result might be that we stopped enjoying them. We might come to see that we had enjoyed them previously because we were unwittingly reading them in the light of our own preoccupations; once this became less possible, the drama might cease to speak at all significantly to us.The fact that we always interpret literary works to some extent in the light of our own concerns - indeed that in one sense of ‘our own concerns’ we are incapable of doing anything else - might be one reason why certain works of literature seem to retain their value across the centuries. It may be, of course, that we still share many preoccupations with the work itself; but it may also be that people have not actually been valuing the ‘same’ work at all, even though they may think they have. ‘Our’ Homer is not identical with the Homer of the Middle Ages, nor ‘our’ Shakespeare with that of his contemporaries; it is rather that different historical periods have constructed a ‘different’ Homer and Shakespeare for their own purposes, and found in these texts elements to value or devalue, though not necessarily the same ones. All literary works, in other words, are ‘rewritten’, if only unconsciously, by the societies which read them; indeed there is no reading of a work which is not also a ‘re-writing’. No work, and no current evaluation of it, can simply be extended to new groups of people without being changed, perhaps almost unrecognizably, in the process; and this is one reason why what counts as literature is a notably unstable affair.
