Autonomy, as a revolutionary perspective realising itself through self-organisation, is paradoxically inseparable from a stable working class, easily discernable at the very surface of the reproduction of capital, comfortable within its limits and its definition by this reproduction and recognised within it as a legitimate interlocutor. Autonomy is the practice, the theory and the revolutionary project of the epoch of “fordism”. Its subject is the worker and it supposes that the communist revolution is his liberation, i.e. the liberation of productive labour. It supposes that struggles over immediate demands  are stepping stones to the revolution, and that capital reproduces and confirms a workers’ identity within the relation of exploitation. All this has lost any foundation.
In fact it is just the opposite: in each of its struggles, the proletariat sees how its existence as a class is objectified in the reproduction of capital as something foreign to it and which in its struggle it can be led to put into question. In the activity of the proletariat, being a class becomes an exterior constraint objectified in capital. Being a class becomes the obstacle which its struggle as a class has to overcome; this obstacle possesses a reality which is clear and easily identifiable, it is self-organisation and autonomy.
