Quadrant is an Australian literary and cultural journal. Since 1956 it has defended freedom of expression, high culture and the Western tradition. The magazine takes a conservative position on political and social issues, describing itself as sceptical of 'unthinking Leftism, or political correctness, and its "smelly little orthodoxies"'. Quadrant reviews literature, as well as featuring essays on ideas and topics such as politics, history, universities, and the arts. It also publishes poetry and short stories. It is published ten times per year and its current cover price is A$8.50. Keith Windschuttle was appointed Editor in late 2007.
