Just as people bring to a narrative all the experiences they have in their lives and come away differently from having a text to which they closely or only distantly relate, so too do their perceptions vary. When people have a wealth of experiences, their perceptions are usually clearer and more logical than those who have only been told many things and have little by which to measure what they perceive.

It is true that everyone has his or her own ideas, but those ideas are largely shaped by cultural norms and experiences.  You grow up around certain ideas and types of people, and those are the ideas you will support.  It is true that some people like things others do not, but it is more than just individual personality that affects these choices.  It is really just part of the nature versus nurture debate.  We like certain things and have certain tastes, but they may reflect where we come from more than we realize.

This idea certainly seems true, however, there seems to be no way to truly test whether or not we see the world differently from one another. Of course, the "truth" of the statement is going to depend on what we mean by "see". 

If we are talking about political and social perspectives there is a chance that we may actually have quite a bit in common with one another in these areas as they are mediated heavily by language. 

Fundamentally though, I agree entirely. 

Since no two people think exactly alike, it stands to reason that no two people view the world in exactly the same way. Our life experiences do effect the way we view the world, but it is more than that. Our temperament, our mind, and even our very personalities effect the way we view the world and the way our experiences shape us. 

Of course, literally, everyone sees and perceives the world differently.  There are actual conditions that make people's experiences different, such as color blindness, synaesthesia, and being differently abled.  Besides the literal differences, as #2 and #3 have already mentioned, our personal experiences also inform the way we perceive the world around us.  The way we have been raised, our personalities, and our religious and cultural backgrounds, among other factors, influence our varied reactions to this world.

I agree. Everyone's experiences are unique, and though some people are, as has already been observed, predisposed to having a certain disposition that colors how they see things, ultimately our situation has a great deal to do with it. A person's religion, occupation, family situation, level of education, or nation of origin can help shape their worldview. Because nobody has exactly the same experiences, they can't see things exactly the same.

I completely agree with this statement.  I would add, however, that I think that some of the way we see the world comes from our inborn personalities.  For example, I think that some people are more inclined to be optimistic and others are more inclined to be pessimistic.  This seems to be inborn and yet it impacts the ways in which we see the world.
