There are a few passages is Freire’s Pedagogy of the Oppressed where he talks about (or is translated as talking about) libertarian education. For example:
This was troubling me, as I associate libertarianism with the neoliberalism of Reagan and Thatcher (and we Scots really, really do not like Thatcher). But then I realised (see my earlier post from today) that it was also possible to be a left libertarian, and further that this was actually where my political sympathies already lay – and that although I’d always called myself an anarchist, libertarian socialist was a much neater way of describing my political beliefs.
The raison d’etre of libertarian education, on the other hand, lies in its drive towards reconciliation. Education must begin with the solution of the teacher-student contradiction, by reconciling the poles of the contradiction so that both are simultaneously teachers and students.
The term “libertarian” has an idiosyncratic usage in the US and Canada, reflecting, I suppose, the unusual power of business in these societies. In the European tradition, “libertarian socialism” (“socialisme libertaire”) was the anti-state branch of the socialist movement: anarchism (in the European, not the US sense).
