Green is about periodization as it relates to the worldview and the Western view of history. It is organized into three sections that discuss the history of Western periodization, whether the current practice of Western periodization is functional, and world periodization. Talk about various approaches or methods to periodization. This article also took me quite some time to read, often searching for words to hopefully have a better understanding. For me it was one of the most challenging reads. I like that Green's article is well organized into manageable sections. The article asks whether the periodization designed to study European history can be applied to the study of world history. I think he can't. If that specialized periodization were applied to world history, those who teach, study, and learn world history would likely only see a very European view of world events and how they mattered to the European powers, giving a partial view of history. Through these four articles on periodization, different concepts of what periodization is have been exposed through simple definitions. Additionally, they talk about how important it is to use periodization carefully because it can have a big impact on how information is interpreted. Overall I found the four reads informative and interesting, despite some of them
