Knowledge is a familiarity with someone or something, which can include facts, information, descriptions or skills acquired through experience or education. It can refer to the theoretical or practical understanding of a subject.
It can be implicit or explicit; it can be more or less formal or systematic. In Philosophy, the study of knowledge is called epistemology; the philosopher Plato famously defined knowledge as justified true belief.
However, no single agreed upon definition of knowledge exists, though there are numerous theories to explain it. The following quote from Benrand Russell’s “The question how knowledge should be defined is perhaps the most important and difficult.
This may seem surprising: at first sight it might be thought that knowledge might be defined as belief which is in agreement with the facts. The trouble is that no one knows what a belief is, no one knows what a fact is, and no one knows what sort of agreement between them would make a belief tree.
Knowledge can help us to know. What is the life? Why we live? Why God create us? And why we try to improve our life? When we understand or get knowledge we are able to answer these questions. In that time we are able to enjoy our life.
At the end knowledge is the best thing and has special value that we always must be getting it than other things in the world.
