ABSTRACT: Discussions about freedom of speech and academic freedom today are about the limits to those freedoms. However, these discussions take place mostly in the higher education trade press and do not receive any serious attention from academics and educationalists. In this paper several key arguments for limiting academic freedom are identified, examined and placed in an historical context. That contextualisation shows that with the disappearance of social and political struggles to extend freedom in society there has come a narrowing of academic life and a new and impoverished concept of 'academic freedom' for a diminished idea of the human subject, of humanity and of human potential . 相似文献
