Public Reason is a concept i just came across. I do not really have a handle on it yet.
I came across it here in a Study of Public Reasoning while reading up on the social science work going into the construction of the Cyberinfrastructure.
And while digging for more i came across this explanation of public reason in a Legal Theory blog.
I also found this abstract which is intriguing - Reconstructing Public Reason.
I think, but not completely sure yet, it can be a useful concept for civicaccess.ca in that public reasoning requires data and also for a way to encourage public debate in the construction of infrastructures as in large technological system need public reason for their construction and public reasoning in how they are constructed. The term also seems to show up in mediations of democracy and pluralism.
I also think it ties in with collectivist understandings of territory and nation, not the essentialist ones, but the fabricated, manufactured and imagined ones.
