knowledge

According to Oxford English Dictionary, the term 'knowledge' is defined variously as "expertise, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject"[1] It is "known in a particular field or in total" [2] Its also " facts and information or awareness or familiarity gained by experience of a fact or situation".[3] Although there has been Philosophical debates in general start with "Plato's formulation of knowledge as 'justified true belief'"[4}. "There's no single agreed definition of knowledge presently, nor any prospect of one, and there remain numerous competing theories” [5].
Knowledge gaining involves complex cognitive processes; these are perception, “learning, communication, association and reasoning. The word knowledge is also used to mean; the confident understanding of a subject with the ability to use it for a particular reason if suitable” [6].
“The definition of knowledge is a matter of on-going debate among philosophers in the field of epistemology. “The classical definition is described, but not ultimately endorsed by the Philosopher ‘Plato’ has it that in order for there to be knowledge at least three criteria must be fulfilled; that in order to count as knowledge, a statement must be justified true, and believed. Some claim that these conditions are not sufficient, as Gettier case examples allegedly demonstrate. There are a number of alternatives proposed, including Robert Nozick’s arguments for a requirement that knowledge 'tracks the truth' and Simons additional requirement that we do not want to say that those who meet any of these conditions 'through a defect, flaw, or failure' have knowledge. Richard Kirkham suggests that our definition of knowledge requires that the believer's evidence is such that it logically necessitates the truth of the belief.” [7]
‘”Plato was a Greek philosopher who together with his teacher, Socrates and students, Aristotle, helped to lay the philosophical foundations of the Western Culture” [8].
“ Robert Nozick was an American Philosopher, Pellegrino University professor at Harvard University, He did additional but less influential work in such subjects as decision theory and Epistemology” [9].
“Simon Blackburn is a British academic atheist philosopher known for his efforts to popularize philosophy” [10]
“Richard Kirkham was an American philosopher, his published works are ‘Theories of Truth’ and ‘Does the Gettier problem Rest on a mistake? ‘” [11]
