Wisdom is a concept of personal gaining of knowledge, understanding, experience, discretion, and intuitive understanding, along with a capacity to apply these qualities well towards finding solutions to problems. It is the judicious and purposeful application of knowledge that is valued in society. To some extent the terms wisdom and intelligence have similar and overlapping meanings. The status of wisdom or prudence as a virtue is recognized in cultural, philosophical and religious sources.
Measurement instruments that use these criteria have acceptable to good internal consistency and low test-retest reliability (r in the range of 0.35 to 0.67).
Many, but not all, studies find that adults' self-ratings of perspective/wisdom do not depend on age. This stands in contrast to the popular notion that wisdom increases with age.
There is an oppositional element in Christian thought between secular wisdom and Godly wisdom. The apostle Paul states that worldly wisdom thinks the claims of Christ to be foolishness. However, to those who are being saved Christ represents the wisdom of God. (1 Corinthians 1:17-31) Also, Wisdom is one of the Seven gifts of the Holy Spirit according to Anglican, Catholic, and Lutheran belief.
In Islam, according to the Qur'an, all of the prophets of the Old Testament, Jesus, as well as the Prophet Muhammad were chosen by God, mostly in times of political or moral crisis, to represent his wisdom. The Prophet Muhammad said that: "Fearing God in your actions and intentions, and knowing that Almighty God is watching you wherever and whenever you are is the head/peak of wisdom". In addition, Islam also mentions that a wise man with the name of Luqman once told his son to: "Sit with the learned men and keep close to them. Allah gives life to the hearts with the light of wisdom as Allah gives life to the dead earth with the abundant rain of the sky"
In Taoism Practical Wisdom may be described as knowing what to say and when to say it.
In Norse mythology, the god Odin is especially known for his wisdom, often acquired through various hardships and ordeals involving pain and self-sacrifice. In one instance he plucked out an eye and offered it to Mímir, guardian of the well of knowledge and wisdom, in return for a drink from the well. In another famous account, Odin hanged himself for nine nights from Yggdrasil, the World Tree that unites all the realms of existence, suffering from hunger and thirst and finally wounding himself with a spear until he gained the knowledge of runes for use in casting powerful magic. He was also able to acquire the mead of poetry from the giants, a drink of which could grant the power of a scholar or poet, for the benefit of gods and mortals alike.
A standard philosophical, (philos-sophia: literally "lover of wisdom"), definition says that wisdom consists of making the best use of available knowledge. As with any decision, a wise decision may be made with incomplete information. The technical philosophical term for the opposite of wisdom is folly.
In his Metaphysics, Aristotle defines wisdom as knowledge of causes: why things exist in a particular fashion.
In addition to experience there are a variety of other avenues to gaining wisdom. For example, Freethinkers and others believe that wisdom may come from pure reason and perhaps experience, while others believe that it comes from intuition or spirituality.
Beginning with the ancient Greeks, European culture associates wisdom with virtue. Metis and Athene are associated with wisdom from earliest times. For example, many philosophers talk about the virtue of wisdom in relation to courage and moderation, and in the Roman Catholic church, wisdom (Prudence) stands with justice, fortitude and moderation as one of the four cardinal virtues. Plato's dialogues mention the virtue of wisdom, as knowledge about the Good and the courage to act accordingly. The Good would be about the right relations between all that exists. The Good, as a Platonic Form, would involve the perfect ideas of good government, love, friendship, community, and a right relation to the Divine. Perhaps the search or love of wisdom is more important than any proven claim. Socrates only claimed to know that he did not know, but this he was very certain of, and he showed the many contradictions in the claims of his fellow citizens.
Holists believe that wise people sense, work with and align themselves and others to life. In this view, wise people help others appreciate the fundamental interconnectedness of life.
Nicholas Maxwell, a modern philosopher, argued that the basic aim of academic inquiry ought to be to seek and promote wisdom — wisdom being construed to be the capacity to realize what is of value in life for oneself and others, wisdom thus including knowledge and technological know-how, but much else besides.
Wisdom is the goal of philosophy. Philosophy attempts to understand reality, and how we should live in the light of reality. Genuine wisdom therefore requires achieving this kind of understanding. Anyone who discusses wisdom without having clear philosophical understanding is the blind leading the blind.
