International Philosophy Day is celebrated on the third Thursday of November each year. It was established by the United Nations Educational, Scientific and Cultural Organization (UNESCO) and was first celebrated on November 21, 2002.
Philosophy is the study of general and fundamental problems, such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument. The word “philosophy” comes from the Greek φιλοσοφία (philosophia), which literally means “love of wisdom”, and was originally a word referring to the special way of life of early Greek philosophers.
