Lisa's Guide to Historical Thinking

For some people, what's significant about the Titanic was that so few people were rescued. For others, it's the construction of the ship, which might have contributed to the speed of its sinking. Some people could note human error, the mistakes made by the captain and crew. Lastly, one might focus on the fact that there weren't enough lifeboats to hold everyone on board. All these are important. The historian chooses which is most important to his or her interests.
