“The possibilities of real or hypothetical agreement or consensus in the world are extremely limited. This does not, of course, imply that it might not be an extremely good idea to conduct as extensive discussions as possible, develop discursive institutions, and so on. We might have all kinds of good reasons for this apart from the excessively cheerful idea that free discussion would give us automatic access to a common good.”
