theory in public
There are numerous instances of this sense. Here's one. Tom Hayden, in a draft of the document that became The Port Huron Statement, tenets for the founding of SDS and more generally of the political side of 1960s student-led counterculture:
"The house of theory [is] not a monastery. I am proposing that the world is not too complex, our knowledge not too limited, our time not so short, as to prevent the orderly building of a house of theory, or at least its foundation, right out in public, in the middle of the neighborhood."
There are many ways to see this. I like to conceive of it as a pedagogy.
After all, the document was written by students. Weren't they thinking about the way they had been and were being taught? They wanted something different. Mainly two things different: 1) not so pragmatic, contingent; 2) not cloistered, but out there.
