What exactly is knowledge?
If we take a dictionary definition of the term knowledge then it is the information, skills, and understanding that you have gained through learning or experience.
And if we take definitions of the definition of knowledge then information are the facts or details that tell you something about a situation, person, event etc. A skill is the ability to do something well, especially because you have learned and practised it. To gain is to gradually get more and more of a quality, feeling etc, especially a useful or valuable one. Learning is knowledge gained through reading and study. Experience is knowledge or skill that you gain from doing a job or activity, or the process of doing this.
Definitions are inescapably tautological. Because we cannot avoid the circularity of definitions we take it as a constant and move on.
Perhaps the most important of the definition of the main definition is from the term experience. In short, knowledge is a process. When the process of knowing comes to an end – death – the possession of information ends. It is this point that we must keep in mind (ironically as information) at all times in the pursuit of knowledge and philosophy.
