People who do not believe in higher powers and God approach life rationally, critically assessing the events taking place in it. Paying tribute to the intelligence and fortitude of everyone who relies on the power of their intellect, humanists and their supporters celebrate the Festival of Human Light on December 23. This worldview system is based on the dignity and value of the individual, his right to happiness and the free search for the meaning of life. The light of reason, and not divine power, as followers of various religious movements believe, can help a person in this.
