Norberto Bobbio,liberal socialism and the problem of language

Norberto Bobbio's theory of procedural democracy grows out of his refusal of totalising knowledge in favour of a belief that the ‘sparrow's’ view is preferable to that of the ‘eagle’. Only in this way is irreducible human difference protested. History is reduced by Bobbio from both its liberal and its marxist presumptions about its total sense to a realm of partial empirical proof for assertions about the good. It cannot be understood as more than a contested area of facts whose overall laws and telos cannot be known. The good can only be agreed upon in a debate. Thus he sees politics as a place where all voices must be heard and consensus arrived at on contingent and limited goods. Thus practically politics becomes today the practice of more representative democracy in more places. The condition for such a practice is a liberal socialist regime of rights. His valuable theory of procedural democracy as the defender of difference in society finds its limits in an undeveloped theory of communication across difference. What is a common acceptable, undistorted language for the debate?
