Critics of the ‘co-operative university’ have questioned our commitment to the idea of the ‘public university’. Indeed, co-operatives are anti-statist, but they also exceed the idea of ‘public ownership’ with that of ‘common ownership’, a social form of property that is the antithesis of the right of free alienability (which distinguishes capitalist private property). In short, co-operative higher education is entirely compatible with the idea of the ‘public’ if we reconceive it as an autonomous, open, democratically governed ‘commons’: An academic commons, democratically controlled by academic and support staff, students, cleaners and others.
