Is Wiredu’s consensus democracy what Habermas’s discourse principle looks like in a council?
This term I have been reading Wiredu's essays on consensus alongside Habermas with a few older students, and they keep asking a question I want to put to a wider group.
Wiredu argued that traditional Ashanti politics, at least at the level of councils of elders and chiefs, worked by consensus rather than majority rule, and he proposed a "non-party polity" for modern African states built on that principle: representatives chosen without parties, deliberating until agreement. His essays on this are collected in Cultural Universals and Particulars (1996).
Habermas's discourse principle says that the only valid norms are those that could meet with the agreement of everyone affected, as participants in rational discourse.
On the surface they look like cousins: both put agreement among all concerned at the centre of legitimacy.
But I see differences. Wiredu's consensus is practical: agreement on what to do, not necessarily on what is true. A minority can accept a decision without agreeing it was right, because its view was heard and weighed. Habermas's principle is an idealising test; he never expected actual parliaments to reach it, and in practice his democracy runs on majority votes informed by public discussion.
So: are these the same idea at different levels, or genuinely different ideas that happen to share a word? And which is more realistic?
