What are the liberal arts and sciences? They are simply fields in which knowledge is pursued disinterestedly--that is, without regard to political, economic, or practical benefit. Disinterestedness doesn't mean that the professor is equally open to any view. Professors are hired because they have views about their subjects, views that exclude opposing or alternative views. Disinterestedness just means that whatever views a professor does hold, they have been arrived at unconstrained, or as unconstrained as possible, by anything except the requirement of honesty.
