Philosophy is the study of the nature of reality and existence, of what is possible to know, and of right and wrong behavior. It comes from the Greek word phílosophía, meaning 'the love of wisdom.' It is one of the most important fields of human thought as it aspires to get at the very meaning of life.

World Philosophy Day was introduced in 2002 by UNESCO (the UN Educational, Scientific and Cultural Organization) with the following objectives:

  1. to renew the national, subregional, regional and international commitment to philosophy;
  2. to foster philosophical analysis, research and studies on major contemporary issues, so as to respond more effectively to the challenges that are confronting humanity today;
  3. to raise public awareness of the importance of philosophy and its critical use in the choices arising for many societies from the effects of globalization or entry into modernity;
  4. to appraise the state of philosophy teaching throughout the world, with special emphasis on unequal access;
  5. to underline the importance of the universalization of philosophy teaching for future generations.

In 2005 the UNESCO General Conference proclaimed PDF document that World Philosophy Day would be celebrated every third Thursday of November.
