World Philosophy Day

World Philosophy Day is observed around the world on November 17. Philosophy is an essential part of human life and science, making this day the perfect opportunity to reflect, ask questions, and explore deep ideas.

History

World Philosophy Day was first held on November 21, 2002, at the initiative of UNESCO. The UN later adopted the idea and declared it an international event. In 2005, it was decided to celebrate this day annually, encouraging people to study philosophy and apply its principles in their daily lives. Philosophy provides tools for solving problems, understanding society, accepting mistakes and differences, and analyzing concepts.

The roots of philosophy trace back to Ancient Greece in the 6th century BC, with major figures such as Socrates, Pythagoras, and the Sophists.
