Self and world are correlated, and so are individualization and participation. For this is just what participation means: being a part of something from which one is, at the same time, separated. Literally, participation means “taking part.” This can be used in a threefold sense. It can be used in the sense of “sharing,” as, for instance, sharing a room; or in the sense of “having in common,” as Plato speaks of the methexis (“having with”), the participation of the individual in the universal; or it can be used in the sense of “being a part,” for instance of a political movement. In all these cases participation is a partial identity and a partial nonidentity. A part of a whole is not identical with the whole to which it belongs. But the whole is what it is only with the part. The relation of the body and its limbs is the most obvious example. The self is a part of the world which it has as its world. The world would not be what it is without this individual self. One says that somebody is identified with a movement. This participation makes his being and the being of the movement partly the same. To understand the highly dialectical nature of participation it is necessary to think in terms of power instead of in terms of things. The partial identity of definitely separated things cannot be thought of. But the power of being can be shared by different individuals. The power of being of a state can be shared by all its citizens, and in an outstanding way by its rulers. Its power is partly their power, although its power transcends their power and their power transcends its power.
