The study of history provides many benefits. First, we learn from the past. We may repeat
2
U
mistakes, but, at least, we have the opportunity to avoid them. Second, history teaches us what

S E
T
questions to ask about the present. Contrary to some people’s view, the study of history is not the

C IS
S
memorization of names, dates, and places. It is the thoughtful examination of the forces that have
T
shaped the courses of human life. We can examine events from the past and then draw inferences
N
about current events. History teaches us about likely outcomes. Another benefit of the study of
O
M I
history is the broad range of human experience which is covered. War and peace are certainly
S
covered as national and international affairs. However, matters of culture (art, literature, and
IS
D
music) are also included in historical study. Human nature is an important part of history:

emotions like passion, greed, and insecurity have influenced the shaping of world affairs.
