Greatness is a concept of a state of superiority affecting a person or object. Greatness can also be referred to individuals who possess a natural ability to be better than all others. The concept carries the implication that the particular person or object, when compared to others of a similar type, has clear advantage over others. As a descriptive term it is most often applied to a person or their work, and may be qualified or unqualified. An example of an expression of the concept in a qualified sense would be "Stalin was one of the greatest wartime leaders". In the unqualified sense it might be stated "Stalin achieved greatness within his own lifetime", thus implying that "greatness" is a definite and identifiable quality. Application of the terms "great" and "greatness" is dependent on the perspective and subjective judgements of those who apply them. Whereas in some cases the perceived "greatness" of a person, place or object might be agreed upon by many, this is not necessarily the case, and the perception of "greatness" may be both fiercely contested and highly individual.
