Knowledge
Knowledge is a body of understanding and skills that is constructed by people and increased through interaction with other people and with information.[1]
Knowledge is an understanding, or model, about people, objects or events, derived from information about them.[2]
Knowledge provides a structure for interpreting information. Knowledge is the application of expert opinions, skills and experience to data and information for decision making.[3]
Knowledge is one of the hardest thing to define.But we know that Data,Information and Knowledge is different from each other,and data is the lowest level,knowledge is the highest level of meaning,but also data is the most faithful one, knowledge is the least one,because it in some sence twists the truth to meet man's mind to understand.
Theoretically,knowledge must has its context,otherwise,it's meaningless.That's its nature.But as a man,when we use knowledge,in most circumstence,we forget its intact background,so that means,we often use knowledge in a wrong situation,at least,we could say,in a less fidelity.In this way,we could say,any knowledge is a kind of stereotype,we should use it carefully.
Words is used to express our mind,but words are not alway fit our thoughts perfectly.So words just convey our thoughts in some degree,not 100 per cent.
These two intermediary:knowlege and words is set between each two parts of communication.So we could come to a conclusion that:When in serious communicaion case,words is not enough to convey information.Especial when fedelty is needed to convey,words is almost useless.
In this way,we say that knowledge is a barrier of truth.
Knowledge is a tool but also a barrier of truth. We shouldn't take it as truth itself.
