Contemporary philosophy is the present period in the history of Western philosophy beginning at the early 20th century with the increasing professionalization of the discipline and the rise of analytic and continental philosophy. The phrase "contemporary philosophy" is a piece of technical terminology in philosophy that refers to a specific period in the history of Western philosophy (namely the philosophy of the 20th and 21st centuries). However, the phrase is often confused with modern philosophy (which refers to an earlier period in Western philosophy), postmodern philosophy (which refers to some philosophers' criticisms of modern philosophy), and with a non-technical use of the phrase referring to any recent philosophic work. Professionalization Process Professionalization is the social process by which any trade or occupation establishes the group norms of conduct, acceptable qualifications for membership of the profession, a professional body or association to oversee the conduct of members of the profession, and some degree of demarcation of the qualified from unqualified amateurs. The transformation into a profession brings about many subtle changes to a field of inquiry, but one more readily identifiable component of professionalization is the increasing irrelevance of "the book" to the field: "research communiqués will begin to change in ways [...] whose modern end products are obvious to all and oppressive to many. No longer will [a member's] researches usually be embodied in books addressed [...] to anyone who might be interested in the subject matter of the field. Instead they will usually appear as brief articles addressed only to professional colleagues, the men whose knowledge of a shared paradigm can be assumed and who prove to be the only one able to read the papers addressed to them." Philosophy underwent this process toward the end of the 19th century, and it is one of the key distinguishing features of the contemporary philosophy era in Western philosophy. Germany was the first country to professionalize philosophy. At the end of 1817, Hegel was the first philosopher to be appointed professor by the State, namely by the Prussian Minister of Education, as an effect of Napoleonic reform in Prussia. In the United States, the professionalisation grew out of reforms to the American higher-education system largely based on the German model. James Campbell describes the professionalisation of philosophy in America as follows: Professionalization in England was similarly tied to developments in higher-education. In his work on T.H. Green, Denys Leighton discusses these
