Perspective has many definitions, such as the ability to understand what is important and what isn't. And the capacity to view things in their true relations or relative importance.
Consider this excellent example of how differently people view the same subject in this ancient fable.
Four blind men were asked to examine an elephant and to describe its appearance.
The first blind man felt the elephant's leg and declared that the creature was like a tree.
The second blind man felt the elephant's enormous side and said that it was like a wall.
The third man felt the tail and was positive that the elephant was like a rope.
The fourth felt the tusk and likened it to a spear.
