Perspective is based upon the environment one is brought up in. Perspective is based on many different factors. If someone is blind from the day they are born, then they would have a completely different understanding of reality then someone with 20/20 vision. Another factor, is the home someone is brought up in, a christian run household is different then a muslim run household. They beliefs in the two households are different, the food, the culture, and the holidays. These are all elements of different perspective that influence the understanding of reality.
