"A theory is exactly like a box of tools. It has nothing to do with the signifier. It must be useful. It must function. And not for itself. If no one uses it, beginning with the theoretician himself (who then ceases to be a theoretician), then the theory is worthless or the moment is inappropriate. We don’t revise a theory, but construct new ones; we have no choice but to make others. It is strange that it was [Marcel] Proust, an author thought to be a pure intellectual, who said it so clearly: treat my book as a pair of glasses directed to the outside; if they don’t suit you, find another pair; I leave it to you to find your own instrument, which is necessarily an investment for combat. A theory does not totalise; it is an instrument for multiplication and it also multiplies itself. It is in the nature of power to totalise and it is your position. and one I fully agree with, that theory is by nature opposed to power. As soon as a theory is enmeshed in a particular point, we realise that it will never possess the slightest practical importance unless it can erupt in a totally different area. This is why the notion of reform is so stupid and hypocritical. Either reforms are designed by people who claim to be representative, who make a profession of speaking for others, and they lead to a division of power, to a distribution of this new power which is consequently increased by a double repression; or they arise from the complaints and demands of those concerned. This latter instance is no longer a reform but revolutionary action that questions (expressing the full force of its partiality) the totality of power and the hierarchy that maintains it. This is surely evident in prisons: the smallest and most insignificant of the prisoners’ demands can puncture [Rene] Pleven’s pseudoreform [Pleven was the prime minister of France in the early 1950]. If the protests of children were heard in kindergarten, if their questions were attended to, it would be enough to explode the entire educational system. There is no denying that our social system is totally without tolerance; this accounts for its extreme fragility in all its aspects and also its need for a global form of repression. In my opinion, you [Foucault] were the first-in your books and in the practical sphere-to teach us something absolutely fundamental: the indignity of speaking for others. Pe ridiculed representation and said it was finished, but we failed to draw the consequences of this “theoretical” conversion-to appreciate the theoretical fact that only those directly concerned can speak in a practical way on their own behalf."
