Forcing us to think the break itself

For it is the very principle of the radical break as such, its possibility, which is reinforced by the Utopian form, which insists that its radical difference is possible and that a break is necessary. The Utopian form itself is the answer to the universal ideological conviction that no alternative is possible, that there is no alternative to the system. But it asserts this by forcing us to think the break itself, and not by offering a more traditional picture of what things would be like after the break.
