Now I have been trying to make visible the constant articulation I think there is of power on knowledge and of knowledge on power. We should not be content to say that power has a need for such-and-such a discovery, such-and-such a form of knowledge, but we should add that the exercise of power itself creates and causes to emerge new objects of knowledge and accumulates new bodies of information. One can understand nothing about economic science if one does not know how power and economic power are exercised in everyday life. The exercise of power perpetually creates knowledge and, conversely, knowledge constantly induces effects of power. The university hierarchy is only the most visible, the most sclerotic and least dangerous form of this phenomenon. One has to be really naâ€¹ve to imagine that the effects of power linked to knowledge have their culmination in university hierarchies. Diffused, entrenched and dangerous, they operate in other places than in the person of the old professor.
