What means to be wise
About wisdom Aristotle wrote in his book Metaphysics: "In the measure that it is the dominant and sovereign science, to which others, as if slaves were, do not replicate, it is fair to apply to the science of the end and the good, because in view of this the other things exist, but insofar as it has been defined as the science of the first causes and of the knowable by excellence, it is just as well that the science of the substance be the wisdom", Book III, Cap. 2.
For Aristotle, wisdom is fundamentally a science about the "know-how", that is, wisdom is practical prudence: for example, the architect is wise in his work, the doctor is wise in healing.
In scholastic philosophy the concept of wisdom is extended, it is not only a practical prudence, but also the most excellent essence and perfect virtue (spiritual gift).
Thomas Aquinas in his work Summa Theologiae defines: "God is the wisdom itself" and explains that the Word of God is "wisdom engendered" by the gift of counsel.
In spirituality we can know something by understanding its main characteristics, in the letter of the apostle James in the New Testament we have a description of the main characteristics of wisdom and, that the good that is a nature, proceeds of wisdom:
"Who is wise and understanding among you? Let them show it by their good life, by deeds done in the humility that comes from wisdom", James 3:13.
"But the wisdom that comes form heaven is first pure, then peace-loving, considerate, full of mercy and good fruit, impartial and sincere", James 3:17
God is the wisest and most understood (gift of science). We can say that wisdom is a gift from God; a gift for St. Thomas is "delivery without duty of return", Question 38, A 2 (Summa Theologiae). The gifts are perfections.
The gift by excellence is love, but since God is the source of the good, "Only God is good", Mark 10:18; this love is the Love for the good, the wisdom and the good come from the love of God. God is the Charity itself: " Who does not love does not know God, because God is Charity", 1 John 4: 8
