The triumph of the human spirit is used throughout literature, art, pop culture and even religion in reference to the incorporeal aspects of man that help him overcome his adversities and reach his goals. It tends to incorporate various faculties that human beings have, such as the intellect, emotions and creativity of a person.
The human spirit also tends to be used in relation to the idea of human beings' sense of will that enables them to do extraordinary things, even under the worst of circumstances. In this way, religions use the idea of the human spirit to represent the source of mankind's sense of free will. The Bible also tends to describe the human spirit in a more metaphysical sense, where the human spirit is the source of a human's being.
The idea is based around the notion that human beings face pain and suffering throughout their lives. However, the human will to succeed, to persevere against all odds, allows people to accomplish their goals or survive in circumstances that would otherwise defeat or kill them. Even today, writers tend to equate the idea of the human spirit being triumphant in times of natural disasters, where people help one another to survive and recover from the devastation caused by overwhelming circumstances.
