Abstract
Modernity has been accompanied by a regain control of religious power cores by the State that were previously outside it. However, one can show that this break is superimposed another noteworthy discontinuity: the emergence of a new concept of power, dealing with life itself and not with its margins, which would be the biopolitics. It is possible to identify conceptual levers that engage all these changes in one of a key thinkers of this political modernity, Spinoza. While he demonstrates the need for political power of emancipation from religious and resumption, he takes part in a new way of thinking the exercise of power.
