The major in history exists because of that special environment in which man lives: time. History is a way of understanding the ways men and their societies change over time. Furthermore, history properly understood should focus not just on the events and changes, but also on the reasons for those changes. Thus, history stresses more than just knowledge of places or facts; rather, it stresses analysis and insight. For the Catholic, history assumes a special importance. By the fact of the Incarnation, at a specific place, in a specific time, God Himself has sacralized human life, and, indeed, time itself. The Catholic believes that history begins in God and ends in God.
