Wisdom is one of many human mental capabilities. Mental vitality is stereotypically associated with youth and mental decline with old age. However, also aging is a price of wisdom. The connection between neurological decline (senility, dementias) and wisdom development during aging is referred to as the paradox of wisdom.
Research on wisdom has become popular primarily in the last two decades. There is no generally excepted deﬁnition as yet, but a general consensus exists that wisdom is a concept, which can be studied from various aspects, similarly to information.
