The world is filled with many perspectives. This is a truism.
In light of this, it is probably best to start with the statement that all societies are socially constructed. This is to say that people create culture. When we begin to think about this fact, we will be able to see that there are many perspectives on account of this very fact.
Let me give an example.
If you live in the Middle East, it is probably a foregone conclusion that there is only one God. To think something other than monotheism is odd, to say the least. However, if you move over to Europe, not many people would agree. Their perspective is very different. In fact, most French would probably not even believe in the divine. If you move over the India, you will realize that the differences are even greater, as polytheism is the norm.
All of these differences are differences in prespective. Moreover, all of these are rooted in the fact cultures are socially constructed.
