Differentiated book- It has a historical context with research of the time-Magic and Fetishism by Alfred C. Haddon.This book contains a historical context, where past events or the study and narration of these events are examined. The historical context refers to the circumstances and incidents surrounding an event. This context is formed by everything that, in some way, influences the event when it happens. A fact is always tied to its time: that is, to its time. Therefore, when analyzing events that took place tens, hundreds or thousands of years ago, it is essential to know the historical context to understand them. Otherwise, we would be analyzing and judging what happened in a totally different era with a current perspective.Alfred Cort Haddon was born on May 24, 1855, near London, the oldest son of John Haddon, head of a firm of founders and printers.
