Knowing vs. Perceiving

When you perceive something, you are forming your own personal opinion of a situation. Your perception cannot be "wrong", because everyone is entitled to draw their own conclusions by making connections to prior experiences. One person can swear that their English teacher is the nicest person ever, and another can firmly believe that same teacher is cruel, but neither of these people is necessarily "right." When you perceive, you are not looking for everyone to agree with you, you are simply using your mind to form your own point of view. For example, my brother believes my car is the slowest vehicle ever, and that a hybrid is the worst invention anybody could ever think of. I, on the other hand, could not be any more ecstatic about the car, and I feel that it is perfect. Neither of us has a better reason than the other as to why our opinion is right; which is why there are always (at least) two sides to every story. Some of us feel that having a women as our president is exactly what the United States needs, and then there are those of us who won't even consider the option. We perceive things so that they make sense in our heads, and we don't need others to agree with us to make them sound right. We create our own ideas from events that have happened in the past, and we use the past to help us make sense of the present.
To know something is different, because you can't really "know" anything unless you have proof. I KNOW my hair is brown, but someone else may see it as a different color. I can say my hair is brown as much I want to, but I have no way of really knowing how anybody else sees it. When you know something, it has been established, and there is no way for anyone to prove it wrong. You know two people are married because they have a certificate to prove it. You know who a child's mother is because tests can be taken as a form of evidence. You know 2+2=4 because you have been taught this, and there is no way to prove otherwise. The difference between knowing and perceiving is having proof. You CAN’T prove the color of your hair to someone who is color blind, because they see things differently than you do. You CAN know who your parents are because scientists have ways to prove this.
You can perceive without knowing because you don't need true facts to form an opinion. You can know something because you have been given information, but if you perceive it in your own version, you don't know it until your opinion can be backed up with proof. While I may not agree with something my mother does, my father is entitled to thinking that what she does is right. Both of us can have our own opinion of what we believe is right, because we perceive things differently. To know right from wrong can be taught, but that doesn't necessarily mean that every person agrees with one another. If everyone agreed, there would be no wars, no arguments about politics, and the world would be a lot more peaceful than it is today.
No form of knowledge is superior to another, because knowledge is constantly changing. We may be able to prove something one day, but the next day we could discover something else that completely changes this fact. Both perceiving and knowing require a great amount of thought, but the only way you can actually know something is if there is no way to prove it wrong.
