The public sphere is a social entity with an important function and powerful effects in modern, democratic societies. The idea of the public sphere rests on the conviction that people living in a society, regardless of their age, gender, religion, economic or social status, professional position, sexual orientation, ethnicity, race, or nationality, should be able to publicly express their thoughts, ideas, and opinions about issues that matter to them and impact their lives. This expression should be as free as possible in form and function and should operate through means and methods that people themselves deem suitable, so not via channels that are official or state-sanctioned. The classic Habermasian idea of the public sphere is that it is used by private individuals (not officials or politicians) who should be able to converse with each other in a public-spirited way to develop opinions that impact state or public-body decisions and policies. Also contained within this classic idea is the conviction that public sphere conversations should be rational (i.e., logical, evidence-based, and properly motivated and argued using an acceptable set of rhetorical devices) in order to convince others of the usefulness of a position, statement, or opinion. In commonsensical, political, and journalistic understandings, the public sphere is a critical component of a democracy that enables ordinary citizens to act as interlocutors to those who hold power and thereby hold them to account. As such it is one of the elements whereby democracy as a system is able to claim legitimacy as the “rule of the people.” Journalism’s imbrication in the social imaginary of the public sphere dates back to 17th- and 18th-century Europe when venues like coffee houses, clubs, and private homes, and media like newspapers and newsletters were being used by a mixture of gentry, nobility, and an emerging middle class of traders and merchants and other educated thinkers to disseminate information and express ideas. The conviction that journalism was the key vehicle for the conveyance of information and ideas of public import was then imbedded in the foundations of the practice of modern journalism and in the form exported from Western Europe to the rest of the world. Journalism’s role as a key institution within and vehicle of the public sphere was thus born. Allied to this was the conviction that journalism, via this public sphere role and working on behalf of the public interest (roughly understood as the consensus of opinions formed in the public sphere), should hold political, social, and economic powers to account. Journalists are therefore understood to be crucial proxies for the millions of people in a democracy who cannot easily wield on their own the collective voices that journalism with its institutional bases can produce.
