outside the field. (The entire difference between utopianism and realism is to be found here.) In this way. the tendencies to sectarian splits are continually being counterbalanced by the necessities of competition which mean that, in order to triumph in their internal struggles, professionals have to appeal to forces which are not all, and not totally, internal (unlike the situation in the scientific or artistic field, in which appealing to non-professionals discredits you). Avant-garde splinter groups can bring into the political field the logic characteristic of the intellectual field only because they have no base: they thus have no constraints upon them, but they also have no real power. Functioning as

The former group draws the party towards the logic of the intellectual field which, when pushed to the limit, can deprive it of all temporal power; the latter group has on its side the logic of
The political field is thus the site of a competition for power which is carried out by means of a competition for the control of non-prufessionals or, more precisely, for the monopoly of the right to speak and act in the name of some or all of the non-professionals. The spokesperson appropriates not only the words of (he group of non-professionals, that is. most of the time, its silence, but also the very power of that group, which he helps to produce by lending it a voice recognized as legitimate in the political field. The power of the ideas that he proposes is measured not. as in the domain of science, by their truth-value (even if they owe part of their power to his capacity to convince people that he is in possession of the truth), but by the power of mobilization that they contain, in other words, by the power of the group that recognizes them, even if only hy its silence or the absence of any refutation - a power that the group can demonstrate by registering its different voices or assembling them all together in the same space. It is for this reason that the field of politics - in which one would seek in vain for any authority capable of legitimating the chances of legitimacy and any basis of competence other than class interests, properly understood - always swings between two criteria of validation: science and the plebiscite?
